What’s Wrong with Your HVAC Unit? | Tips from Your Chattanooga, TN Heating and AC Service Provider

Let’s face it – a home or business’s heating and ac unit is among its most important features. More than a luxury, heat and air conditioning is a necessity in today’s South. With the extreme temperatures in Chattanooga, TN, your HVAC unit is necessary year-round, for your health as well as your comfort.

When your HVAC is acting up, most homeowners want to know what part is malfunctioning. That way, you will have more information to give your repair technician. And it can also help you get an idea about how much the repair will cost.

Make certain that you choose a licensed, insured, reliable and trusted Chattanooga, TN company for your heating and ac repairs. This is the only way you can be assured that the work is guaranteed. That kind of peace of mind is important.

So, when your HVAC system is malfunctioning, pay attention to what it is doing differently. Any changes you see, smell, feel, or hear could be a clue to where the problem lies.

Your Heater Isn’t Heating at All

If there’s nothing happening when you turn on your heat, you likely have a problem at the power source. If you have checked the pilot light or circuit breaker and found nothing amiss, the problem may be with your power company.

Your Heater Isn’t Heating the House Enough

When you can tell your heater is on, but it isn’t heating the house to a comfortable level, the first place to start is your filter. Though it may seem like a small thing, a lot of problems are caused by a clogged filter.

When your filter gets clogged, the airflow in your HVAC unit is reduced significantly. So, how often should you change the filter in your HVAC system?

The truth is, the answer is different for different households. If you run your heater continuously, you should change the filter every month. Factors that could cause your filter to get clogged quicker include the presence of pets with fur in the house.

Your heating and ac technician can help you determine a maintenance schedule that includes routine filter changes.

Your Heater Clicks from Off to On Continually

Theoretically, when your house reaches the desired temperature, your heater will switch off to maintain the temperature. The part that regulates this is the thermostat.

If your heater switches on just as soon as it kicks off throughout the day, your thermostat is the likely culprit. Try changing your temperature settings. If this doesn’t change the situation, you could have a problem with airflow or your filter may be clogged.

Your Heater Makes a Lot More Noise

HVAC systems can make noise while they are operating. But if yours has started to make a lot of noise, or starts making different noises, you may need to have a HVAC tech take a look at it.

Your Heater’s Blower Won’t Stop Running

When your blower keeps running continuously, the part that is supposed to cut it off is not working. That means you most likely have a problem with the limit switch.

Your Air Conditioner Doesn’t Blow Cold Air Out

If your air conditioner is blowing, but the air isn’t cold, there could be several things causing it. One of the first things you should check is the filter. A clogged filter can hinder airflow and block the cold air. Change the filter if it is dirty.

The problem could lie with the thermostat. The thermostat on your heating and ac system regulates the temperature of your house. Try setting your thermostat on its lowest temperature setting. If you don’t notice a difference, you may need a new thermostat.

Inspecting the HVAC unit outside can let you in on a few problems. Make sure that the area around the system is free of leaves, weeds, and debris. Don’t plant bushes or trees close to the unit. You should plant them at least two feet away. Be sure to remove any leaves that gather on the top.

Look for coolant leaks around the air conditioner. Your HVAC needs a certain amount of refrigerant to keep your home cool. Too little can keep your air conditioner from cooling properly. However, too much can damage your system. Only a Chattanooga, TN heating and ac repair specialist will be able to put the proper amount in your unit.

Your Air Conditioner Doesn’t Blow Out Any Air

If you don’t feel any air at all coming from your air conditioner, something is not getting the power to do its job. There are a couple of simple things you can check. First is the thermostat.

Your thermostat requires batteries. If the batteries are dead, replace them. If they are still working, make sure the HVAC unit is set on the proper mode. Ensure the temperature is set where you want it.

If none of this works, make sure the circuit breaker hasn’t tripped. Flip the switch on, if it has.

An air conditioner that still doesn’t work after this has a problem beyond your help, you will need to contact a Chattanooga, TN heating and ac professional for assistance.

Your Air Conditioner Is Dripping

The problem could be with your condensate line. This is the pipe that comes out of your air conditioner. If it is clogged, your heating and ac tech can flush it out with compressed air.

If you have a refrigerant leak, ice could form on the condenser coils and cause a drip. Frozen coils could also be a sign of debris surrounding the unit and cutting off the airflow. This could also indicate a dirty air filter or an obstruction in the duct work.

Your Air Conditioner Doesn’t Cool the House Evenly

The summers in Chattanooga, TN can put even the best heating and ac units to the test. But if your air conditioner is giving an uneven performance, it might be caused by leaks in your duct work, improper insulation, or vents and registered that are blocked.

If the rooms that are hotter face the south, you may find that blackout curtains keep the sun coming through the windows from overheating the room.
