HVAC Maintenance Plans & Tune-Ups
Regular inspections and cleanings that prevent costly breakdowns and keep your system at its peak — spring for cooling, fall for heating.

What we do
Most breakdowns we see start as small problems that a tune-up would have caught. A maintenance plan puts your system on a schedule, so you don’t have to remember — and you’re far less likely to need emergency AC repair on the hottest week of the year.

How often should my HVAC system be serviced?
Twice a year is best: the AC in spring before the Texas heat, and the heating in fall before the first cold snap. Regular service prevents breakdowns and keeps energy bills down.
What is included in a tune-up or maintenance plan?
A full inspection and cleaning of the system, checking refrigerant levels, electrical parts, the thermostat, drain lines and airflow, plus a filter check. Ask us about a maintenance plan so you never miss a visit.
Do you provide same-day AC repair?
Whenever possible, yes. Call 214-382-8601 early in the day and we will do our best to get a technician to you the same day — including weekends during the Texas heat.
