Frequently asked — preventive maintenance in Costa Mesa

How much does HVAC maintenance cost in Costa Mesa?

Annual single-system tune-up: $99-$149. Semiannual plan (cooling + heating): $199-$279 with 10% off any repair + priority dispatch.

When should I schedule maintenance?

AC in spring (March-April). Furnace in fall (September-October). Doing both on the same visit is fine if your system type supports it.

What does maintenance actually do?

Restores system to design spec: clean coils bring SEER back up, new capacitors prevent motor failures, refrigerant-charge verification prevents compressor damage. Most gains come from cleanliness, not parts.

Should I repair or replace my AC unit?

As a rule of thumb, if repair costs exceed 50% of a new unit's price, or your system is over 10 years old and needs a major repair, replacement is usually the better investment. {company}'s technicians will give you an honest assessment.

What SEER2 rating should I buy in Costa Mesa?

14.3 SEER2 (the 2023 federal minimum) saves vs. a 10+ year old unit. Going to 17 SEER2 pays back in 6-8 years on Costa Mesa's cooling hours. Above 20 SEER2 only pays back if you stay in the home 12+ years.

What is the best thermostat setting for energy savings?

Set your thermostat to 68°F in winter and 78°F in summer when home. A programmable or smart thermostat can automatically adjust temperatures when you're away or sleeping, saving 10–15% on energy costs. {company} installs and configures smart thermostats.
