3 Tips for Resolving Basic Cooling & Heating System Problems, Exeter, New Hampshire

When your HVAC stops working in the middle of winter, it can be stressful. However, many issues that commonly pop up can often be quickly resolved without making a service call. Below are some normal issues that can arise with a cooling and heating system in the winter and how you can easily fix them.

3 Solutions for Common Cooling & Heating System Problems

1. Checking the Thermostat

It is not uncommon for HVACs to blow cold air when you want them to produce heat, and many times the problem has to do with the thermostat. If you have a programmable thermostat, it might become confusing to tell if the setting has been changed from “cool” to “heat,” so it is always important to double-check. After ensuring you’re on the right setting, you should then turn up the temperature at least five degrees to see if the system kicks on and starts heating your home.

2. Turn on the System

Next to thermostat issues, HVAC technicians often find that the lack of heat can often be traced back to a furnace that has not been turned on. When you make the swap to heating, check for a switch on the wall or somewhere near the furnace and flip it on. You might also want to check your circuit breaker to make sure the fuse has not flipped.

3. Change the Air Filter

Many times, this problem is caused by a dirty air filter clogging up the system with dust and other debris. Unfortunately, if you ignore this simple maintenance, it could become a serious problem, resulting in repairs to your heat exchanger and drastically shortening your system’s life span.
