Inspecting the HVAC System

Falling leaves and budding trees are semi-annual signals to inspect HVAC systems to make sure heating and air conditioning flow freely and efficiently. Some mechanical components, like the flue pipe that expels carbon monoxide, should only be checked by a professional. But you can eyeball other HVAC parts and save money on house calls and fuel bills.


Air filters, which clean the air returning to your HVAC system, are the easiest and most obvious components to check. Yours should be dust and dirt-free because you have cleaned or replaced them once a month. If you’ve fallen behind on air filter maintenance, vacuum or rinse them under a hose or faucet, or replace disposables. You can also contact us and we can inspect the filter for you.


Exposed ductwork in your basement, attic, or loft is easy to inspect. Make sure you look for signs of peeling duct tape and loose fittings around seams, dirt streaks that indicate escaping air, dents in metal, or a collapsed or torn section of flex ducts. If you notice any of these issues, make sure to contact us as soon as possible, so we can inspect the HVAC system for you.


Inspect air return grills and HVAC registers for dust, dirt, and pet hair that impeded airflow. Open and shut registers to ensure they work. Make sure furniture is not covering or blocking the vents.


Be sure outside compressors are unobstructed by vines, shrubs, and leaves. Check that condenser unit fins are straight and undamaged. Place a level on top of units to detect a tilt, which hurts efficiency. If not level, slip a shim under the unit. Remove the top panel and inspect the fan blades for damage, but don’t repair a bent blade yourself, it is recommended to contact us to replace the blade.
