HVAC Services FAQs
These are some of the questions customers ask about our comprehensive HVAC services in Denton, MD.
How Long Should an Average HVAC System Last?
On average, HVAC systems should last between 15 and 20 years with proper maintenance. Heat pumps usually last between 10 and 15 years, while many furnaces can last up to 30 years.
How Often Should I Replace My HVAC System’s Air Filter?
You should replace your HVAC system’s air filter every 30 to 90 days. Also, keep the register and the vents in your home clear of obstructions at all times.
What Do SEER Ratings Mean?
SEER (Seasonal Energy Efficiency Ratio) ratings measure the energy efficiency of your cooling system. Higher SEER ratings indicate better energy efficiency and lower energy costs.
How Often Should I Have My HVAC System Inspected and Maintained?
We recommend that you have your HVAC system inspected and maintained twice each year — once in the spring before the cooling season and again in the fall before the heating season. Our maintenance HVAC services in Denton, MD, help prevent system breakdowns while maximizing energy efficiency.
