Thermostat Problems

The Thermostat device is what controls and balances the heat produced for comfort by turning the system on and off. When a thermostat malfunctions, your system doesn’t properly regulate itself by turning on and off. It may produce too much heat or not enough both of which are equally bad. 

Lack of Routine Maintenance

As mentioned earlier, lack of maintenance can lead to a number of problems which causes more damage in your HVAC system. If you neglect proper maintenance, you might increase the risk of sudden breakdowns, increased costs, and other issues due to dysfunctional HVAC systems.

Wear & Tear of Mechanical Parts

A furnace is made up of many mechanical parts that need to be maintained and in working order to fully operate the furnace properly and bring comfort to you. Proper maintenance prevents excessive wear and tear on parts and in the long run reduces the lifetime cost of the system and extends the life of the unit.

Clogged & Dirty Filters

Filters are designed to keep dust and debris out of the system and by design the filters catch the vast majority of the dust that builds up. Because of the build-ups, the airflow won’t go through as much as necessary and as efficient enough to produce quality airflow. This may also cause more damage if filters are not replaced.
