BTUs (British Thermal Units):

AC units are rated in BTUs, which indicate their cooling capacity. Higher BTUs mean more cooling power. You’ll need to calculate the required BTU capacity for your space.

The ac unit problems to check before air conditioner replacement

Before you decide to replace your air conditioner, or choose the best time to replace ac unit, it’s wise to troubleshoot some common problems. Here are some AC unit issues you can check to see if a repair might be a more cost-effective solution than a full replacement:

Basic Checks:

  • Thermostat: Make sure your thermostat is set to “cool” and the desired temperature is lower than the room’s current temperature.
  • Power: Ensure the AC unit is turned on at the thermostat and the breaker controlling the unit hasn’t tripped.

Airflow Issues:

  • Air Filter: Ensure that there is no clogged air filter restricts airflow, or reducing cooling efficiency.
  • Blocked Vents: Ensure furniture, curtains, or other objects are not blocking vents and return air grilles.
  • Dirty Indoor Unit: Remove dust on the evaporator coil which can reduce airflow.

Refrigerant Issues:

Low Refrigerant Levels: Refrigerant leaks can lead to decreased cooling performance. Refrigerant handling requires a certified professional.
