Questions and answers
Short answers, with links to the guide or service page that covers each topic in depth.
About the call
Who answers when I call the number on this site?
An independent HVAC contractor who serves the Garland area. AC Garland does not answer calls or send anyone out.
Is AC Garland a contractor?
No. It is a referral service and holds no air conditioning license. Whoever picks up runs their own firm, apart from this website.
What should I have ready before calling?
What the system is doing, where the indoor unit sits, roughly how old the outdoor unit is, and whether you own or rent.
Cooling
My AC runs but the house will not cool. Where do I start?
With the filter and the thermostat, then the checks on the AC repair page.
There is ice on the copper line outside. Is that normal?
No. Switch cooling off and run the fan; the frozen coil guide explains why.
Can I still get my old R-22 system fixed?
Yes. Reclaimed R-22 is still sold for service. The repair or replace guide covers when that makes sense.
Permits, rules and licenses
Do AC repairs need a permit in Garland?
Some do, including coil replacement. See Garland permit rules.
Which refrigerant must a new system use?
New split systems installed after January 1, 2026 need one with a GWP below 700. The replacement page explains what that means for a swap.
How do I check a contractor's license?
Use the TDLR license search. The hiring guide lists the other checks.
Heating
The furnace lights and then shuts off. What is that?
Often a dirty flame sensor. Other causes are on the heating repair page.
Who supplies gas to Garland homes?
Atmos Energy. The power and gas guide also covers electric service.
