Your HVAC system should be serviced at the start of the cooling season and again at the beginning of the heating season. When you take good care of your HVAC system, it is less likely to break down in an emergency. There are signs that indicate your system is not working correctly. High energy costs can indicate your system is running too hard to keep you comfortable. A system that turns on and off without changing the temperature may have a number of causes for the short-cycling. When your HVAC system is not able to keep up with your heating or cooling demands, it's time to call an HVAC contractor for help.
When Your Heating System Short Cycles
Short cycling occurs when your system turns on and off without impacting the temperature in your home. This can occur when your system is overheating, and it shuts off to avoid burning out. Your thermostat could be broken or set to fan incorrectly. When you hear your heating or cooling system turn on, but the temperature doesn't improve, it's time to investigate further.
You Aren't Getting Any Heat
Your heating system can turn on, but it is blowing cold air. This can occur when the heat exchanger is no longer working properly. If your system turns on and the blower works, the issue isn't with your electrical system or the fan. You might have a dirty air filter that needs to be cleaned, your fuel supply could be low, or there might be an issue with your pilot light.
When Your System Makes Loud Noises
You may hear squealing or banging noises coming from your HVAC system. If the loud banging noise is in your furnace, this is likely caused by a delay in ignition. You might hear belts squealing that need to be lubricated or have a problem with a blower that needs to be replaced. Any new noises coming from your heating or cooling system should be investigated immediately to make sure your system is safe to run.
Heating contractors understand that you might need small repairs to your HVAC system over the heating season. Even when you get your system serviced at the start of the year, problems can crop up that need to be dealt with. Change out your air filter, and pay attention to blocking any vents in your home. If your system is not working properly, it's time to call for help.
