Lack of Maintenance: One of the primary reasons for AC unit failure is a lack of regular maintenance. Over time, dust, debris, and other contaminants can accumulate in the system, leading to reduced efficiency and potential damage. Neglecting routine maintenance like cleaning or replacing filters, checking refrigerant levels, and inspecting components can put a strain on the system, causing it to fail.

Electrical Issues: Electrical problems can also contribute to AC unit failures. Faulty wiring, tripped breakers, or issues with the capacitor, compressor, or fan motor can disrupt the electrical supply to the system. Electrical failures may result from improper installation, power surges, or general wear and tear.

Refrigerant Leaks: Refrigerant is crucial for the cooling process in an air conditioning system. However, leaks can occur over time due to corrosion, vibrations, or physical damage to the refrigerant lines. When the refrigerant levels drop significantly, the AC unit's cooling capacity decreases, causing it to work harder and potentially fail. Low refrigerant levels can also put stress on the compressor, leading to further damage.

These are not the only reasons for AC unit failures, and other factors such as component wear, age of the system, or environmental conditions can also contribute to malfunctions.

The suitability of a heat pump or mini split unit for heating your home in Lake of the Ozarks will depend on several factors, such as the size of your home, insulation levels, and the local climate.

The average low temperature in January is around 21°F, and the average high temperature in July is around 90°F.

A heat pump or mini split unit can provide efficient heating in mild to moderate winter conditions, but they may struggle to keep up with the demand for heat in extremely cold temperatures. In areas where winter temperatures regularly drop below freezing, it's important to have a supplemental heating source, such as a furnace or electric resistance heater, to provide additional heat when needed.

If you have a well-insulated home that is appropriately sized for the system, and the heat pump or mini split unit is properly installed and sized for your needs, then it may be able to heat your home adequately throughout the winter months. However, it's recommended to consult with a licensed HVAC professional to determine the most suitable heating system for your home based on your specific needs and local climate.

Wallin Heating and Cooling is the Lake of the Ozarks' trusted, on-time HVAC contractor. Call today at (573) 745-4821 or schedule service at www.wallinhvac.com.

1. Change or Clean Air Filters Regularly 

Dirty filters restrict airflow, making your air conditioner work harder to cool your space, and leading to increased energy consumption and potentially expensive repairs. To avoid this, it is recommended to clean or replace your air filters every 1-3 months, depending on usage. 

2. Clean the Coils 

The evaporator and condenser coils in your air conditioner can accumulate dirt, dust, and other debris over time. This can reduce the effectiveness of your AC system, increase energy consumption, and even lead to component failure. Cleaning these coils regularly can help ensure efficient cooling and prevent damage to your system. 

3. Keep the Condensate Drain Clear

The condensate drain in your air conditioner removes the moisture that accumulates during the cooling process. Over time, this drain can become clogged with dirt, algae, or other debris, leading to water damage and even mold growth. It is important to regularly check and clean the condensate drain to avoid these issues. 

4. Check the Thermostat Settings

Make sure your thermostat is set to the correct temperature and mode to avoid overworking your AC system. Set the temperature to a comfortable level and switch the fan to auto mode to ensure that the system is only running when necessary. 

5. Schedule Regular Maintenance 

It is a good idea to have a professional HVAC technician inspect and tune-up your air conditioner annually. This can help identify and address any potential issues before they become more serious, ensuring that your AC system runs efficiently and reliably all summer long. 

To ensure your air conditioner is ready for summer on the Lake Call Walling Heating and Cooling!  Best time to get your Air Conditioner Checked and Maintenance completed?  Now before it gets crazy on the lake!  Call 573-745-4821 or request service at www.wallinhvac.com 

1. Thermostat has NO POWER

Nothing appears on the Screen. Normally it should display the room Temperature. Check-change the batteries in the thermostat if you insert new batteries and nothing displays the thermostat itself may be malfunctioning.

2. Furnace or Air Conditioner will not Shut Off

A thermostat that is not working properly may cause your HVAC equipment to run and not shut off. If you notice your HVAC unit has been running for a long period or time or is not shutting off go to your thermostat and shut it to the OFF position if your HVAC unit continues to run you have an issue.

3. Furnace or Air Conditioner will not Turn On 

If you turn your thermostat on and increase the temperature your furnace should turn on, if it does not come on then you have bad wiring or other issues that are causing your thermostat and Furnace to not communicate.

4. Thermostat and Room Temperature do not Match

When a thermostat is working properly, it should display an accurate temperature of what it feels like inside your home. But if the room feels much hotter or colder than the display temperature, that means your thermostat can’t accurately measure the room’s temperature.

Wallin Heating and Cooling offers Thermostat Replacement Services

Your thermostat is critical in making your home comfortable by communicating the desired temperature to your HVAC system. If your thermostat is damaged or unreliable it could lead to bigger problems in the future. Call Walling Heating and Cooling to diagnose your Thermostat and make sure it is working properly.

What should you do to get your furnace working well before the cold sets in?  

Some of these will appear very simple but a checklist of 3 things you will want to do before winter is in full swing. 

1. Change your thermostat from Cool to Heat. 

Set the temperature a couple of degrees higher than the current room temperature. If you don’t hear the furnace kick on within a minute or two double check the connections and batteries of your thermostat if that does not work may want to check other power sources to your furnace or you may want to call a Heating Contractor to check out your system. 

2.  Test Run your Furnace.

Test run your furnace before cold weather sets in.  While your heating unit is running listen for strange or abnormal sounds (banging – rattling, etc) Walk around to your vents and make sure warm are is flowing freely.  

3. Change the air filters.

Change your furnace filters every few months. Or, if you have a permanent electrostatic filter, you can wash and reuse it. Cleaning or replacing your filters regularly keeps debris out of your HVAC system and can prolong its life.  You can easily tell if your filter needs to be changed with a visual inspection.

SEER Rating 

Seasonal Energy Efficiency Ratio or Rating – Benefits of a higher SEER rating or ratio is that the HVAC system greater efficiency in certain conditions and greater indoor comfort in the summer months especially in regions like Lake of the Ozarks. 

Get the appropriate Size of HVAC System 

Make sure you buy the appropriate size system.  Too much heating and cooling capacity can make you HVAC system start and stop which causes added wear on components and having too little means you may sacrifice comfort because your system simply can not keep up. 

A certified and well-trained HVAC Tech will be able to fit your home or business with the appropriate size and seer rating based upon several factors in your home.

Cost matters

Do not mistake picking a HVAC based only on PRICE.  Some HVAC systems will be more efficient, some systems may have lesser warranties and their warranties cover less parts or labor, Less usually means a lesser SEER rating which means more wear and tear and more possible problems.  

Consult with a Heating and Cooling Professional they should be able to provide you with a couple of options and explain the pro’s of each.

Call Wallin Heating and Cooling Today for a Free Consultation and Estimate 573-745-4821 

• If your system is more than 12 years old, it's likely much less efficient than a new system.
• Musty or dry air often indicates a poorly operating HVAC system.
• The cost of a new system can be balanced by energy savings and reduced repair costs.

• On average, new HVAC systems provide up to 7% greater energy efficiency than the prior year's models.
• Newer systems typically require fewer repairs.
• Advances in indoor air quality (IAQ) technology mean newer systems make your home even more comfortable.

Step 1: Find the right contractor.

A good HVAC contractor will have the knowledge, skills, and training necessary to calculate the type and size of system you will need based upon the layout, size, and type of home you have. Getting the right unit for your home means you will have the most efficient and effective system to heat and cool your home all year long. 

Step 2: Review and discuss system sizing, installation plans, timing, and warranties.

A certified HVAC technician will be able to walk you through all the HVAC system information and give you specifics as to why they recommend the size and system they do, explain what the installation process will entail, and detail your system's warranties. This is also the best time to ask any and all questions you have.

Step 3: Decide on the system and contractor you trust.

You have the information you need; you have asked all the appropriate questions; you have your answers. Time to decide on the company you trust to do the best job and offer the best service.

Step 4: Maintain your air conditioner and furnace.

The key to any HVAC system’s long life and efficiency is ongoing maintenance. Many maintenance tasks can be performed by a homeowner. Your service tech should be able to explain a DIY maintenance schedule for you if you are a DIY type of person. If you wish to have your contractor do ongoing maintenance, ask them what type of plans they have and what they cost.

Step 5: Enjoy your comfort and peace of mind!

1. How large should the air conditioner be?

Your technician or air conditioning contractor should do a J load calculation. This HVAC industry standard calculation takes into account a long list of measurements and characteristics, including your home’s size and layout, your home’s orientation, the amount of shade around your home, the number and location of windows, and much more.

2. How efficient is the new system and what are the warranties?

When deciding on an air conditioning system, look for the ENERGY STAR Rating — these systems meet and exceed the requirements of the EPA. Your system will have a SEER rating (Seasonal Energy Efficiency Ratio). The higher the SEER rating, the better. Higher ratings are more efficient and help you get better energy savings.

3. What are the total costs to install an air conditioner?

When deciding on your new air conditioning system, look at all costs associated with it. 

• How much will it cost to install the new air conditioner?
• How much to remove the old air conditioner?
• What will the air conditioner cost to operate?
• What are the labor costs and are they included in the installation costs?
• Does the cost include all the little extras (thermostats, air quality components, etc.)? 

4. Who will do the work when installing your new air conditioner? 

When researching HVAC contractors to buy from and have install your air conditioner, make sure they have a licensed and certified professional to do the job right the first time. It is best to have the system installed by the same company you buy it from.

5. How much time will it take to install a new air conditioner?

Most air conditioner replacements can be completed the same day. This includes taking out the old air conditioning unit and installing the new air conditioning unit. When meeting with your contractor, make sure you ask because every job and job site is different. Your contractor (if experienced) should give you accurate timelines.

6. Should you purchase a preventative maintenance plan?

The best way to answer this question is simply. You know you. Will you properly maintain your HVAC system on a routine schedule? Will you remember to do it?

Much of the basic maintenance (such as changing filters and performing end-of-season cleaning) and troubleshooting can be done effectively the homeowner, but having a preventative maintenance program can give you peace of mind when you know you have a trained professional who will do a deep diagnostic dive into your system a couple of times a year.

Ask your contractor how much their maintenance plans cost, how often maintenance is completed, and what they do each visit. Many contractors offer plans with other benefits, so make sure you know all the perks.

Air Conditioning equipment, no matter what kind you have, should be inspected, cleaned, and serviced at least once a year.  This will ensure that your Air Conditioner is running in the most effective & efficient manner.  Benjamin Franklin was correct “An ounce of Prevention is worth a Pound of Cure”  

The best scenario is to have the heating system checked in the Fall and the air conditioning checked in the Spring.

Unfortunately, AC Freezing happens and is not that uncommon.

The first thing to do is Turn the AC off and let it defrost, this may take 1 to 3 Hours, turn on just the fan for 30 to 60 minutes this will help circulate air through the coils and help dry them, after this is completed then turn your AC back on, check and make sure it is blowing cold air, if not you should probably call a Professional Service Tech to do a diagnostic check. 

Top 3 Causes of AC Freezing up:

1. Dirty Air Filter 

2. Dirty Evaporator Coils 

3. Refrigerant Leak

1. Filter Problems – Dirty or Plugged Filters

One of the most common AC unit problems is a dirty filter. Dirty filters reduce airflow and can cause parts of the AC to freeze. Make sure to follow your air conditioner manufacturer's recommended filter maintenance. 

2. Fan-Related Issues

Fans blow indoor air over the evaporator to cool it. Another fan blows through the outdoor condenser to expel heat outside. Fans enable the movement of air through the system, and they are an integral part of the AC. A bad motor, wear and tear damage, dirt & debris can all lead to reduced airflow, decreased efficiency, and sometimes, compressor failure. 

3. Coils Require Replacement

Evaporator coils push cool air into the house from the inside, while condenser coils operate outside with the compressor. Both can become corroded or dirty. Clean outside coils with a hose every so often.

4. Insufficient Refrigerant

Refrigerant removes heat and humidity from the air. Leaks in the refrigerant delivery system decrease the efficiency of the cooler, and the temperature may fluctuate as a result. Fixing this issue often requires an HVAC technician to repair the leaks. This process can be time-consuming and expensive.

1 - Check Your Thermostat to make sure it's ON

It may sound simple, but check the thermostat to ensure it is set on  HEAT and that it is programmed at least five degrees above room temperature, then wait to make sure it kicks in and starts. You might be surprised how many service calls are made without checking this! 

Step 1: Check the battery on the thermostat. You may need to change the batteries on your thermostat. If your home's thermostat unit runs on batteries, be sure you are changing them at least once a year, or as needed. “May want to change yearly when you change the fire alarms”

If your thermostat is hard wired and not working it may be best to call a professional and have them trouble shoot your issue.

Step 2: Open the thermostat and gently blow any dust or dirt particles that may be interfering with some connection points

Step 3: Make sure the date and time is correct on electronic or programmable models – Look to see if it is programmed to start at a specific time

Step 4: Check the breaker. If on, turn off the breaker and check the fuse for the furnace.

2 - Furnace is Not Producing Heat

After confirming the thermostat is working - Try to Reset furnace Circuit Breaker

How to Test/check Home Breakers:

Go to your breaker panel and look for the circuit that controls the furnace. Look to see if it’s thrown to the “Off” position, or whether it’s in the middle, if so, manually test the breaker. Flip it back and forth. Make sure it is staying in the "On" position.  This will reset the breaker. If this does not do the trick you will want to call a HVAC Service tech to run some tests.

3 - Furnace is Not Producing Enough Heat

Check and Change Your Clogged Filter

If the furnace doesn't heat the home sufficiently, first ensure that the air filter is clean and in good condition.  This is a simple and essential part of furnace maintenance. One of the most common reasons to have a furnace not working is a clogged filter.  Replacing your furnace filter should be done regularly and goes a long way in protecting your system and improving air quality.

Change your filters as instructed with your systems specs.  Hold it up to the light and if you can not see light it is time to change, if your vents are blowing dusty, dirty smelling air you need to change your filter.

Clean filters can help with seasonal allergies.

4. Safety Switch on Furnace Door

If your furnace is not operating, one of the first things you should do is check the safety switch on the furnace door. A safety switch prevents the fan and burner from coming on while the access panel is removed.  Furnaces have a safety switch that pops out when the door is removed. The door must be in place for the switch to be activated and for the furnace to operate.

If placing the panel or door into the correct placement does not fix the problem you may want to call a Service Tech to trouble shoot the issue.

5 - Keep the Area Around Your Furnace Clean and Unobstructed

This may seem like an obvious tip, but sometimes homeowners with busy lives forget to pay attention to areas of their home like the basement.

Avoid storing flammable substances or materials near your furnace. 

6 - Look at the Burner Flames

Look at the Burner Flames one of the most common failures associated with your burners can come from contamination. You will want to inspect your burners to make sure they are free from debris. When looking if they are burning blue and even they are likely in good shape.  If the flames are yellow and the burners look dirty they more than likely are.  Dust and dirt can accumulate in the summer when your furnace is not running. 

A combination of condensation and soot can cause burners to function improperly, and may cause other furnace problems as well. The burner assembly should be cleaned annually or replaced if the existing one is in poor condition.

We only run our heating systems about half the year, in that time of sitting idle your furnace, mini split or heating unit could become damaged without you knowing.

When a problem or issue arises with your furnace, it’s important to schedule furnace repairs as soon as possible.  Below are some of the signs you may need to contact Wallin Heating and Cooling www.wallinhvac.com or call 573-745-4821.

1. Difficulty Starting your Furnace or It will not Stay Running

If you have a furnace that struggles starting and then shuts off or will not keep running there could be multiple problems to address, wiring, circuit boards, thermostat, or many other internal parts.  Replacing the part or parts should resolve the issue.

2. Bad Smells

Have you noticed a burning smell coming from your furnace? 

• This could be the result of a soot buildup in the heat exchanger or on other parts that are near the flame or heat source.
• If you smell a musty smell, it could be that there is moisture collecting somewhere and potentially creating mold or mildew in your system.
• If you smell Fuel when you first start your unit it should dissipate as the furnace runs but if not you need to call a HVAC Tech immediately to make sure you are safe.

3. Inadequate Heat

One of the most obvious signs that a furnace needs repairs is that the unit is not doing its job. If your furnace is producing no heat or only a low level of heat regardless of your thermostat settings, schedule repairs.

4. Persistent Noises - Strange Noises - Clunking

No furnace or heating unit is silent but any loud clunking, strange, loud noises can indicate that you have a problem or will soon have a problem.  Record the sounds on your phone or do you best to describe them for your HVAC Tech, this will help them hopefully locate the problem area quickly and get you up and running.

Now is the time to check and make sure your furnace is ready to go, frozen or burst pipes are not fun so make sure your furnace is in good running shape before Mother Nature decides to bring on winter. These tips will help you be prepared and save you time and money.

Schedule Preventive Maintenance

A great option to ensure your equipment is running efficiently you should have preventive maintenance performed on your HVAC system by a licensed technician. We recommend in the fall before you turn on your furnace & in the spring before you turn your air conditioner on.

Furnace maintenance for rust and corrosion, cleaning the burners and especially looking for any cracks in the heat exchanger. Even tiny cracks in the heat exchanger can allow poisonous carbon monoxide gas to leak into your home, endangering your family.

Change Your Furnace Filter

Change your existing furnace filter before turning it on for the first time. The filter keeps your air quality high and reduces how hard your furnace needs to work to draw and move the air. If you don’t know the size remove the old one, the size will be marked on the side and then replace it with a new one.

Clear Vent Obstructions

Before turning on your furnace, take the covers off your vents and make sure there is nothing obstructing your vents. Grab your vacuum or shop vac using the hose reach in as far as you can and remove all the dust and nasty stuff that has accumulated.

Seal Drafts – Inspect Insulation 

Look and feel around all your windows and doors for drafts. One of the biggest energy wasters is drafts in your home. Prepare your home for winter by sealing any problem areas. Most all hardware stores will have all the materials you need to cover windows and fill cracks etc. Updating and or making sure your home is properly insulated can cut heating costs significantly.

Start Your Furnace Listen and Look for Any Concerns

Prior to cold weather slowly turn up the temperature of your furnace until it begins to run “Kicks In” soon as it does listen for any unfamiliar sounds, smells etc. If anything seems out of the ordinary call a Certified HVAC Tech to do Preventative Maintenance check. 

Check Your Carbon Monoxide Alarm

Carbon monoxide is an odorless and lethal gas that can be dangerous to your family. Since your heating system will run for an extended period, it's essential to have a working carbon monoxide alarm in your home. They can detect any abnormalities in the air if your furnace releases toxic fumes.

Turn on the alarm to see if it’s functioning correctly. If there’s no response, you may need to get a new one. Another issue could be the batteries, so you’ll need to replace them if necessary.

Maintaining your AC unit is important to ensure it functions efficiently and lasts longer. Here are some DIY steps you can take to maintain your AC:

• Clean or replace the air filter: A dirty air filter can cause your AC to work harder and consume more energy. Check your air filter monthly and clean or replace it as needed.
• Clean the condenser coils: The condenser coils are responsible for releasing heat from your AC. Over time, they can accumulate dirt and debris, which can reduce the AC's efficiency. Use a soft brush to gently clean the coils or hire a professional to do it.
• Check the coolant levels: Low coolant levels can cause your AC to work harder and not cool as efficiently. Check the levels periodically and add more if needed.
• Clear the area around the unit: Make sure there is no obstruction around the outdoor unit. Keep the area around the unit clear of plants, debris, or other objects.
• Inspect the ductwork: Leaks or holes in the ductwork can cause your AC to work harder to cool your home. Inspect the ductwork for any leaks and seal them using duct tape or other appropriate materials.
• Program your thermostat: Setting a programmable thermostat can help you save energy and money by automatically adjusting the temperature when you are not home or asleep.
• Schedule regular maintenance: Consider scheduling an annual maintenance visit with a professional HVAC technician to ensure your AC unit is running efficiently and catch any potential issues early on.

By following these DIY steps, you can keep your AC running smoothly and save money on your energy bills.
