HVAC SERVICES, CARROLLTON, TX | KOALA-T HEATING & AIR

Yes, the City of Carrollton requires a mechanical permit for any HVAC work that replaces major components: compressor, furnace, air handler, or evaporator coil. At Koala-T, our HVAC technicians pull every permit that's required and schedule the city inspection ourselves. Our Texas HVAC license (TACLA00153892E) covers us across Carrollton and every city in our service area. Unpermitted work can void your manufacturer's warranty and create problems at resale, so it's a corner we'll never cut.

The average cost of a full-system HVAC replacement in Carrollton typically ranges from $9,000 to $18,000, depending on the size of your home and the system configuration, as well as its efficiency level and the condition of your ductwork. If your home is based in 75006 and 75007 and has older ductwork, we may need to make additional duct modifications at an extra fee. We provide a free, no-obligation in-home estimate for all our Carrollton customers, and we're more than happy to walk you through every option before you decide.

Yes, if your Carrollton home is served by Oncor Electric Delivery (as the vast majority are), you’re eligible for the 2026 Home Energy Efficiency rebate program. Qualifying high-SEER2 heat pumps can earn rebates up to $3,400 per system. We handle the entire application and apply the rebate as an instant discount on your invoice.

In the DFW climate, the realistic AC unit lifespan is 12–15 years; shorter than the 15–20 year national average. Systems in Texas run approximately 2,200 hours per year versus 1,000–1,400 nationally, and this extra usage shortens their lifespan. If you live in an older Carrollton home (75006/75007) with degraded ductwork or undersized returns, your AC is likely to fail sooner because it's working harder than it should be.

Yes, if another HVAC company has told you that your furnace or air conditioning system needs to be replaced and you’re not sure, call us. Our expert team will come out and diagnose the system independently, then give you our honest assessment. That means we'll always tell it how it is, even if the answer is “the other company was right.” We never charge for second opinions, and there's no obligation for you to choose us.
