Irving requires a permit for every HVAC installation, pulled by a licensed contractor and closed with a final inspection. Here’s how a replacement works in Irving, from sizing to the inspection, and what the federal efficiency and refrigerant rules mean for the system you choose.
Thinking about a new AC in Irving?
Most people replace an air conditioner after a major failure such as a compressor or a large leak, because an old R-22 system is getting expensive to keep running, or because rooms never get comfortable. Before you decide, check these:
- The data plate. The label on the outdoor unit shows the refrigerant type, and the serial number encodes the manufacture date.
- Repair history. Repeat refrigerant top-offs point to a leak that will keep coming back.
- Comfort. Rooms that never cool can mean ducts, not equipment. A bigger unit won’t fix a duct problem.
- The indoor side. The outdoor unit and indoor coil have to match. Replacing only half is a common cause of poor performance.
Still deciding? Read should I repair or replace my air conditioner.
What we install
- Central air conditioners with matched indoor coils
- Heat pumps, if you want one system for heating and cooling. See heat pump installation.
- Furnaces and air handlers paired with the new system
- Thermostats, including smart thermostats. See are smart thermostats worth it.
We install and service all major brands, including Carrier, Trane, Lennox, Rheem, American Standard, York, Daikin, Mitsubishi, Fujitsu, Amana, Bryant and Goodman.
Irving homes and what their age means for your system
Irving’s homes span seven decades, from postwar neighborhoods to new construction. The Census puts the median Irving home at 1986, so many houses have attic ductwork 35 years old or more under a much newer outdoor unit.
The Census counts about 102,512 homes in Irving. Here’s how they break down by decade built:
| Built | Share of homes | What we often find |
|---|---|---|
| 1950s–1960s | About 21% | 60 years or older. Many were built before central air was common, so the ducts and equipment location were added or reworked later. |
| 1970s | About 12% | About 50 years old. Original attic ductwork is common unless it has been replaced. |
| 1980s | About 23% | Irving’s biggest decade. Most have replaced the outdoor unit at least once; the indoor coil, furnace and ducts may be older. |
| 1990s–2000s | About 27% | Many systems from this period were installed with R-22 and have since been replaced or are due. |
| 2010 and later | About 14% | Newer homes and the many apartments and townhomes built in recent years, usually on R-410A equipment. |
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.
Irving’s HVAC rules put a lot of weight on the attic. The City requires that equipment be reachable for service without removing permanent construction, a catwalk with continuous solid flooring to an attic unit, and a switched light and a receptacle at or near the equipment. Older Irving attics often fall short on those, and we tell you up front if a replacement will need them.
Irving permits for HVAC work
- The City of Irving requires a permit for all HVAC installations, which must meet the International Residential Code, the International Mechanical Code and the City’s adopted ordinances.
- A licensed HVAC contractor must get the permit and do the work. A homeowner can install a system in a house they own, live in and have homesteaded, but if refrigerant is being recovered, a licensed contractor has to be on the job. On rental property, a licensed contractor must do all the work.
- Permits are handled through the City’s MGO online portal. When the work is done, the contractor requests a final inspection there.
- Condensate has to drain to an approved location. It can’t discharge into a street or alley.
- Irving’s advice to homeowners: don’t take out a permit for a contractor, and ask to see the permit before work starts. Inspections are at 825 W. Irving Blvd., 972-721-2371.
Dallas Heating and Air Conditioning is registered with the City of Irving as a mechanical contractor. For a replacement, we pull the permit and schedule the inspection.
Because Irving requires the equipment to be reachable for service and an attic unit to have a solid-floored catwalk, a switched light and a receptacle, a replacement in an older Irving attic sometimes includes that work too. We look at the attic on the first visit, so it shows up in your written price instead of as a surprise.
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 Irving 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 Irving 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
- Your current system has failed and repair isn’t worth it
- An R-22 system has a large leak
- The house never gets comfortable even after repairs
- You’re adding or remodeling space and the old system can’t keep up
