    Keeping your air conditioner working properly through the summer doesn’t happen on its own. While there’s no magic formula to keep cool, comfortable air flowing, it all comes down to preventative maintenance. Getting these services doesn’t mean you’ll never need your HVAC system repaired or replaced, but it does help to extend its lifespan as much as possible while keeping unnecessary repairs at bay. Your best bet for reliable performance from your cooling system is to sign up for a program of regular and preventative maintenance. There are also some things you can do yourself, including changing your air filters every 30 to 90 days. It’s also essential to keep your HVAC unit free of leaves, grass, and pollen. The trained and experienced HVAC professionals at First Class Heating and A/C will cover the following items as part of a routine inspection and cleaning service:

    • Performing a comprehensive safety inspection

    • Cost Savings – Keeping your HVAC system clean and free of debris can save you money by avoiding unnecessary repair bills. Catching problems before they get worse is a great way to reduce costs while keeping your system working efficiently. Common problems with HVAC systems include failing to turn on, temperature fluctuations, not cooling the home evenly, leaks, and strange noises. Alert us at the first sign of any of these issues, so we can catch them before they get worse.
    • Efficiency – A dirty or clogged HVAC unit must work harder to achieve the same levels of results clean systems do. The harder your system works, the more electricity it uses, resulting in higher monthly energy bills.
    • Cleaner Air – Regular HVAC maintenance can promote cleaner airflow and reduce allergens, which irritate allergies and asthma. Your family might feel better as a positive side effect of preventative maintenance from First Class Heating and A/C in Millsboro, DE.
