The Energy-Efficiency Of Your HVAC System Depends On Annual Service Checkups

November 1, 2011 | Blog

High-efficiency heating and cooling systems pay considerable dividends in improved fuel usage and savings on energy costs. The longer a system runs, however, the more efficient it will lose. A neglected system can become so inefficient that it cancels out the savings that it originally provided.

Annual service checkups and preventative maintenance are key to maintaining your HVAC system’s efficiency. You and your HVAC technician can cooperate on maintenance tasks that keep your heating and cooling equipment running well.


Clean and change air filters
Filters may seem like trivial parts of your HVAC system, but they are extremely important to the system’s function. Dirty filters constrict needed air flow and can lead to major breakdowns. Check, change and clean filters often – once a month if possible.


Check and calibrate the thermostat
This ensures that the system runs reliably at the temperature level you select and doesn’t waste energy because of incorrect settings.

Inspect and tighten electrical connections
Loose or faulty electrical connections can make your HVAC system unsafe and can lead to early failure of motors and other electric components.

Lubricate motors, fans, and moving parts
Oiling these components keeps the system functioning smoothly.

Check and adjust controls
Your technician will verify proper operation in general and will make sure your heating or cooling system starts, runs and shuts off when it’s supposed to.

Check and clean condensate drain
A clogged drain can lead to water damage and contribute to increased humidity levels in the house.

In your heating system, the technician will check, adjust or repair all components involved with combustion of fuel. He will check fuel connections, gas pressure, burner operation and heat exchanger function.

In cooling systems, he will clean evaporator and condenser coils, check refrigerant levels, and clean and adjust blowers and fans.

Great Company

Great company. Contacted my current AC company to check on my warranty before charging me anything. Saved me a bunch of money and headache if dealing with anything. Would definitely recommend them and use them again.
