Wylie requires a permit for AC and heating replacements and for ductwork, pulled by a City-registered contractor. Here’s how a replacement goes in Wylie.
Replacing an AC in Wylie: start here
- Registration. Your contractor must be registered with the City.
- Refrigerant on the data plate.
- Is it the original system? In a 2000s Wylie home, it often is.
- Ductwork. Wylie requires a permit for ductwork replacement too, so plan it with the equipment.
We go over each of these before you decide.
What we install in Wylie
- Heat pumps
- Ductwork replacement where needed

Wylie homes and what their age means for your system
Wylie is one of the younger cities in this area. The Census puts the median home at 2006, and three-quarters of homes were built in 2000 or later, most of them single-family houses.
The Census counts about 19,511 homes in Wylie. Here’s how they break down by decade built:
| Built | Share of homes | What we often find |
|---|---|---|
| Before 1990 | About 15% | Older homes near downtown Wylie, often with equipment and ducts replaced over the years. |
| 1990s | About 10% | About 30 years old; usually on a second system. |
| 2000s | About 40% | Wylie’s biggest decade. Original systems are 15 to 25 years old, and some still use R-22. |
| 2010 and later | About 35% | Newer homes, mostly on R-410A or newer refrigerants. |
The house’s age doesn’t tell you the system’s age. The data plate on the outdoor unit does, and it’s the first thing we read.
Because so many Wylie homes were built in the 2000s, a lot of original systems are reaching the point where the first big repair, such as a coil or compressor, raises the question of replacement. We give you both options in writing. Wylie’s permit list also includes gas line repairs and electrical service panel upgrades. Those can come up with an HVAC change, such as switching from a gas furnace to a heat pump or adding a larger system, and we’ll tell you up front if your project needs them.
Wylie permits for HVAC work
- The City has a Mechanical Affidavit form for homeowners doing their own work.
- Building Inspection: 972-516-6420, permits@wylietexas.gov.
- The City of Wylie lists air conditioning and heating system installs and replacements, and ductwork installs and replacements, among the work that requires a permit.
- Mechanical contractors must register with the City before they can receive a permit. Registration runs for the calendar year.
Dallas Heating and Air Conditioning is registered with the City of Wylie as a mechanical contractor. For a replacement, we pull the permit and schedule the inspection.
Because Wylie requires a permit for both HVAC equipment and ductwork replacements, if your replacement includes new ducts, we include both in the permit and the written proposal.
Refrigerant and efficiency rules that affect your decision
R-22. The EPA ended the manufacture of new R-22 equipment in 2010 and the production and import of R-22 itself on January 1, 2020. An R-22 system can keep running, but it can only be recharged with recovered or reclaimed R-22. A large leak on an R-22 unit is often the point where replacement makes more sense than repair.
SEER2. Since January 1, 2023, Department of Energy rules require new split-system central air conditioners installed in the Southeast region, which includes Texas, to meet at least 14.3 SEER2 under 45,000 Btu/h and 13.8 SEER2 at 45,000 Btu/h and up. New split heat pumps nationwide must meet 14.3 SEER2. See SEER vs. SEER2.
New refrigerants. Under the EPA’s AIM Act rules, new home air conditioners and heat pumps are moving to refrigerants with lower global warming potential, such as R-454B and R-32. Read what the R-410A phase-out means.
How a Wylie installation works
- Home visit. We check the equipment, ducts, electrical, attic access and the refrigerant type on the data plate.
- Sizing. We size the system for the house, its insulation, windows and ducts, not by copying the old label.
- Written options. Upfront written pricing for each option before any work starts. Financing available.
- Permit. We pull the Wylie permit.
- Installation. Outdoor unit, matched coil or air handler, refrigerant lines, drains, electrical and thermostat as needed.
- Startup and inspection. We charge and test the system, then the City inspects it.
When it makes sense to replace
- The house never gets comfortable even after repairs
- You’re adding or remodeling space and the old system can’t keep up
- Your current system has failed and repair isn’t worth it
- An R-22 system has a large leak
Upfront written pricing before any work starts
Every replacement starts with a written proposal. Here’s what goes in it:
- Each equipment option is priced on its own.
- Financing available.
- What the written proposal covers: the equipment, matched indoor coil or air handler, refrigerant lines, drain, electrical connections, thermostat, permit and inspection.
- Any duct, attic access or electrical work the City will check is listed separately.
