Thermostat and control diagnostics for central air
An AC that won't cool or a furnace that won't heat is uncomfortable any time of year in Orange County. Alpha & Omega repairs and maintains residential heating and cooling systems, from simple tune-ups to full diagnostics.
A handful of checks are safe for any homeowner to do. Refrigerant and electrical work inside the system is not, that's EPA-certified-technician territory, and for good reason.
Common HVAC Repair & Maintenance Problems We Fix
AC not cooling
Low refrigerant, a failing compressor, or a dirty condenser coil are the most common causes.
Furnace not heating or short-cycling
A dirty filter restricting airflow is the single most common cause, check that first.
Thermostat not responding
Dead batteries or a wiring issue are common, low-cost fixes before assuming the system itself has failed.
Strange noises or odors
Grinding often means a motor bearing; a musty smell usually points to mold in the ductwork or drain pan.
Uneven temperatures room to room
Often a duct balancing issue or a failing zone damper, not a problem with the unit itself.
System running constantly
Usually low refrigerant or a unit that's undersized for the space, worth a full diagnostic.

Quick Checks You Can Try First
Check and, if needed, replace the air filter, a clogged filter is the single most common cause of weak airflow and should be checked monthly.
Make sure the thermostat has fresh batteries and is set to the correct mode and schedule.
Check the outdoor condenser unit isn't blocked by plants, debris, or storage items.
Confirm the breaker for the HVAC system hasn't tripped.
