Regular maintenance appointments are essential to keep your HVAC system in good, working order. But just what will your HVAC technician do during that appointment? While the answer does somewhat depend on the age of your system and what problems your technician discovers, a basic maintenance appointment should always include the following components.
Changing the Filter
You're meant to be changing your own air filter every few months, but you can skip the month you have your maintenance appointment. Your HVAC technician will change the filter for you. They may also inspect how dirty your filter is and recommend a different changing schedule or a different type of filter based on what they see.
Cleaning the Burner
Your furnace's burner may accumulate soot and debris, especially as the furnace ages. This can cause the furnace to make booming noises as it switches on. Your HVAC technician can safely clean the burner, making your furnace safer and more efficient.
Safety Mechanism Testing
Your furnace contains several safety mechanisms. They are meant to turn the furnace off it an electrical component fails, the gas supply is interrupted, or something overheats. These safety mechanisms can prevent a fire, carbon monoxide poisoning, and other issues. Your HVAC technician will make sure they are working properly.
Carbon monoxide is a poisonous gas that is always produced when gas is burned. It should be shuttled out of your house via your furnace's ventilation system. However, the vent system can become blocked, or the furnace may suffer certain kinds of damage that cause CO to build up in your home. Your HVAC contractor should test for CO to ensure your home is safe.
Check the Ducts
Most people don't need their ducts cleaned every year, so this is not usually a part of the annual maintenance appointment. However, your HVAC technician will take a look inside your ducts to see how dirty they are. If the ducts are dirty, they'll encourage you to make an appointment to have them clean.
Test Your Thermostat
Your HVAC technician will check the wiring on your thermostat and assess its performance to make sure it is accurately keeping the temperature and is communicating effectively with your furnace. If needed, they might recommend replacing your thermostat or moving it to a new location for greater accuracy.
