Every homeowner depends on their HVAC system to keep their household warm in winter and cool in summer. A failing heating or cooling unit can lead to uncomfortable—and even dangerous—conditions inside your home. Keep your appliances in optimal working order by scheduling prompt repairs when you notice any of these signs.

How to Tell If You Need HVAC Repairs

1. Inadequate Heating or Cooling

A furnace could be emitting cold air for any number of causes, from a clogged air filter and leaky ductwork to an overheated system. An air conditioner blowing warm air usually means that coolant levels are low, which is often the result of a leak somewhere in the refrigerant line. In either of these situations, you won't be able to maintain your preferred temperature inside the home. If the system does produce the desired amount of air, it may not do so evenly, resulting in noticeably warmer or cooler spots around the house.

2. Broken Thermostat

The thermostat is essentially the control center of the entire HVAC system. If it breaks down, you won't be able to manage the heating or cooling of your home. The fix could be something as simple and straightforward as checking and replacing the unit's batteries. However, if that doesn't do the trick, and the thermostat is still unresponsive, a professional should take a look at it. There may be a wiring issue, or the device may have simply reached the end of its life and needs to be replaced.

3. Scraping or Grinding

Scraping or grinding noises are most often the sound of a loose belt or metal part. The jostling component is making contact with other internal parts and creating annoying sounds. If left unattended, the issue—and the noise—will almost certainly worsen until it affects the system's ability to produce cool or warm air.
