Is your HVAC unit failing? Is it not running as cool as you expect it to run? It’s better to know ahead of time if you’re going to be looking at a hefty repair or replacement bill. There are some critical signs to determine whether your HVAC system is heading toward a critical failure and needs service.

Perform some of these quick checks to determine if your unit is close to the end of its life or needs to be serviced. You can do these on your own, though feel free to reach out to us at 707 526 5709 and have us help you if you’re not comfortable doing them all. You should also make sure to stay on top of routine maintenance calls to have your unit checked out and serviced. This is the best way to catch problems before they become larger ones.

These are the biggest signs an HVAC unit is failing:

  • Warm, low-pressure airflow: if the unit is producing air well above expected temperatures, and the pressure is dramatically lower, this could be a sign of a bigger problem. However, it could also be a sign of a very dirty filter blocking airflow. Start by checking your filter, but this could be indicative of something bigger.
  • Unusual odors: this is a telltale sign something is wrong, and the unit needs to be looked at. Either some foreign contaminant has entered the system, or a potentially hazardous electrical situation could mean burnt wires or connections. Either way, have a pro look at it as soon as possible.
  • Inconsistent operation: pay attention to the way your unit is operating. HVAC units are designed to kick on for a period until the temperature reads slightly below the set temperature, and then kick off for a while. Units running constantly without kicking off, or units with short-cycle operations, need to be looked at by a technician.
  • Frozen evaporator: If your unit is blowing warm air and not getting cold as expected, check the evaporator coil in your main unit. If it is frozen, you may need to recharge your system. It could also mean a clogged filter further down the chain as well, so always check with your air filter first. Most systems will need to be recharged and refilled by a professional.
