How Long Do HVAC Units Last?+
The lifespan of your HVAC unit depends on numerous factors, including the type of unit, the manufacturer and how much you use it. A great way to extend your system’s life is with regular maintenance service. At E.A.C. Heating & Air, we provide residential heating and air conditioning maintenance services, as well as commercial maintenance, to keep your systems running in top condition for as long as possible.
How Often Should I Schedule Maintenance for My HVAC System?+
Your HVAC system should receive routine maintenance at least once a year. Regular inspections reduce the risk of costly repairs, help keep your utility bills low, extend the life of your system and make your home safer. We offer a special customer maintenance plan that includes two inspections, cleanings, repair discounts, 24-hour service and numerous other perks.
What Is a SEER Rating?+
A seasonal energy efficiency ratio (SEER) rating indicates how efficient your heating and cooling equipment is. It is calculated by dividing your system’s seasonal cooling output by the energy it uses in watt-hours. The higher the rating your system has, the more efficient it is.
