Preventive Maintenance

Many people don’t realize the importance of regular HVAC maintenance until it’s too late.

At Sherrell Air, we guarantee to service your system quickly and efficiently. Our maintenance service explores every part of your heating and cooling system in order to restore it to the best possible condition and prepare it for when seasons change.

Why Routine Maintenance is Important
Obtaining annual preventive maintenance services provides many benefits for homeowners, whether it’s for a furnace, heat pump, air conditioner, or any other HVAC unit or product. Just like your car or any other well-oiled machine, your HVAC equipment needs routine tune-ups in order to identify potential problems and continue operating in an efficient, safe, and reliable manner. It doesn’t matter if it’s a new installation or if it already has a few years behind it, when properly cared for, your HVAC unit will have a significantly increased life expectancy, serving you for longer and delaying the need for costly repairs or replacements. Not only that, but it can help you save money on expensive electricity bills by cutting down on energy consumption as well as minimizing the risk of dangerous conditions like gas leaks or fire hazards.
In addition to a longer lifespan, increased energy efficiency, and energy savings, proper maintenance also allows you to catch small problems before they turn into bigger, more expensive problems. Plus, your indoor air quality will be significantly better, as well as the overall comfort level of your home or business.
