HVAC Maintenance & Tune-Ups Across Contra Costa
Spring AC and fall furnace tune-ups
A tune-up is a scheduled check-up for your heating and cooling equipment, done before the season it has to work hardest. We do AC tune-ups in spring and furnace or heat pump tune-ups in fall for homes, apartment complexes and commercial buildings. The goal is to catch the worn capacitor, clogged drain or dirty burner before it fails on a 105-degree afternoon or the first cold night of the year.
Why choose Blue Star
Our tune-ups are hands-on. We clean what needs cleaning, test electrical parts under load, measure refrigerant and airflow, and check gas pressure, flame and venting on furnaces. Then we give you a short summary of what we found. If something needs repair, we quote it and you decide; nothing extra happens without your OK. Want your visits handled on a schedule? Our maintenance plan books both tune-ups for you each year.
- Condenser coil cleaning
- Capacitor and contactor tests
- Refrigerant and airflow check
- Condensate drain flush
- Burner, flame and venting
- Filter and thermostat check
Where we work
Maintenance matters most where equipment works hardest. In Antioch, Oakley, Brentwood and Discovery Bay, summer heat and Delta wind pack condenser coils with dust and farm debris, so a spring cleaning makes a real difference. 55+ communities like Summerset in Brentwood and Trilogy at Rio Vista have many systems from the late 1990s and 2000s. Pittsburg and Bay Point rentals benefit from checks between tenants. In Central County, fall furnace checks catch heat exchanger and venting problems in older homes.

Questions we hear
What is included in an AC tune-up?
We shut off power and clean the outdoor condenser coil, check the capacitor, contactor and wiring, measure refrigerant pressures and the temperature split, check blower operation and airflow, flush the condensate drain, and look at the filter and thermostat. We also check the outdoor disconnect and the insulation on the refrigerant lines. You get a summary of what we found and anything that needs attention.
What is checked during a furnace tune-up?
We inspect and clean the burners and flame sensor, test the igniter and safety switches, check gas pressure and the flame, look over the heat exchanger and venting, and check for carbon monoxide at the furnace. We also check the blower, wiring and filter, and run the system through full heating cycles. Heat pumps get a defrost and reversing valve check instead of the burner work.
When should I schedule HVAC maintenance?
Book the AC tune-up in March, April or May, before East County's first 100-degree stretch, and the heating tune-up from September through November, before the first cold snap. Booking early also gets you ahead of the busy season, when repair calls fill the schedule. If you only do one visit a year, put it before the season your system works hardest here: summer.
Is HVAC maintenance worth it?
Usually, yes. Many summer breakdowns trace back to a weak capacitor, dirty coil or clogged drain that a tune-up would have caught. A clean, correctly charged system also uses less electricity and runs quieter, and most equipment warranties expect reasonable maintenance. A tune-up won't make an old system new, but it cuts surprise failures and gives you time to plan a replacement.
How often should I change my air filter?
Check it monthly and change it when it looks gray, or at least every three months for a standard 1-inch filter. Change it more often in summer heat, during wildfire smoke or if you have pets. Thicker 4- or 5-inch media filters can last six months or more. A clogged filter cuts airflow, which can freeze an AC coil and overheat a furnace.
