HVAC Maintenance and AC Tune-Ups in Houston, TX

Tune-ups that catch the weak capacitor or clogged drain before August finds it.

HVAC Maintenance in Houston, TX

HVAC Maintenance built for Houston weather.

Most air conditioners in Houston do not fail at random. They fail on the hottest week of the year, because that is when a part that has been weakening for months finally gives out. A run capacitor drifting out of spec, a contactor with burned points, a clogged condensate drain, a dirty coil, or a refrigerant charge that has been slowly leaking will all show up in a maintenance visit long before they turn into a no-cool call.

Our maintenance visit covers the whole system. We test capacitors and contactors, measure refrigerant pressures and the temperature split, clean the outdoor coil, clear the condensate drain, check the blower, belts and electrical connections, and look at the filter and thermostat. In the fall we check the heating side, including burners, ignition and safety controls on gas furnaces.

Residential and commercial systems get the same visit, scheduled around the building. Twice a year, spring for cooling and fall for heating, is the schedule that makes sense here.

Four steps, no surprises

How a hvac maintenance call works

The same process on a single mini split or a commercial rooftop.

  1. Thermal Solutions trailer with new equipment parked outside a home
    STEP 01

    Tell us what is happening

    Call or send the quote form with the problem, the address and the kind of system. Emergencies go straight to the phone.

  2. Technician testing an outdoor condenser with a meter
    STEP 02

    We measure before we touch it

    A technician tests the system on site. Temperatures, pressures, airflow and electrical, so the repair fixes the cause and not the symptom.

  3. Failed capacitor next to the new replacement part
    STEP 03

    You get the number first

    The estimate is free. You hear what we found and what it costs before any work starts.

  4. Finished ductless condenser install with a clean line set
    STEP 04

    We fix it and prove it

    The work gets done, the system gets tested again, and we do not leave until it is running right.

HVAC Maintenance FAQ

HVAC Maintenance questions, answered.

How often should I service my AC in Houston?

Twice a year is ideal: in spring before the cooling season and in fall before the first cold front. At minimum, once a year before summer.

What does an HVAC maintenance visit include?

Capacitor and contactor tests, refrigerant pressures, temperature split, outdoor coil cleaning, condensate drain clearing, electrical and blower checks, and a filter and thermostat check. Fall visits add a heating safety check.

Do you maintain commercial systems?

Yes. Commercial rooftop units and split systems get the same visit, scheduled around your business.

Is maintenance worth it on a newer system?

Yes. Most manufacturers expect regular maintenance, and a clean, correctly charged system uses less power and lasts longer.
