When it comes to home comfort, nothing offers you a better return on your investment than a great HVAC system. That’s particularly true in regions like Greater Orlando where summers are long, hot and humid. Keeping the AC and heating equipment in good condition is the key to reaping the full rewards of its comfort. While there’s no substitute for professional maintenance plans, there are several tasks you can easily tackle on your own. Other jobs are best left in the hands of an experienced HVAC technician.
