When Should I Do Air Conditioning Maintenance?

You wouldn’t drive your car without changing the oil. The same logic holds true for your ac system. Regular HVAC preventative maintenance is the best way to ensure trouble-free operation and peak performance all year long. Pre-summer maintenance is also important in Florida.

It can help to avoid a system failure in peak summer months when you need it most, and it can also keep your energy bill from getting out of control too.

HVAC Preventative Maintenance Tips

Below you’ll find HVAC preventative maintenance tips to keep your home in constant comfort.

  • For a system that heats and cools: perform maintenance in the spring and fall
  • For cooling system maintenance only: perform maintenance at least once a year, before the cooling season
