AC Replacement in Lewisville, TX

Bottom line: Half of the homes in Lewisville were built before 1992. That means a large share of Lewisville homes are running original or second-generation AC systems, many on R-22 refrigerant that is no longer made. We replace them with right-sized equipment chosen from an independent Manual J load calculation, installed in one day, with a written commissioning report. Call (469) 213-8450.

Why Lewisville Is Replacement Country

Lewisville is a mix. Homes around Old Town and the older subdivisions date to the 1970s and 1980s, while Castle Hills and newer sections went up in the late 1990s and 2000s. Either way, a big share of the city is at or past the age where systems wear out.

We work throughout Lewisville in Denton County, including Old Town Lewisville, Castle Hills, and the Lake Lewisville area. Oncor delivers power across Lewisville, and Atmos Energy supplies natural gas.

Signs Your Lewisville System Is Done

• The outdoor unit is 15 years old or more, or it is the system the house was built with.
• It runs on R-22. R-22 production and import ended January 1, 2020, so every recharge gets more expensive.
• A compressor, coil, or refrigerant leak repair quote approaches half the cost of a new system.
• Upstairs rooms run 5 or more degrees hotter than downstairs, or the house feels damp and clammy in summer.
• Summer electric bills keep climbing on the same thermostat setting.

How We Replace a System

Size it first. An independent company runs Manual J, S, and D on your home so the size is based on your actual house, windows, and insulation, not the tonnage of the old unit. Older homes are often oversized because insulation and windows were upgraded after the original install.

Check the ducts. We inspect returns, supply runs, and connections and tell you what is worth fixing. A new system on choked ductwork never performs the way it should.

Install and commission. New pad, disconnect, line set or properly flushed existing lines, drain, and thermostat. We record startup pressures, temperatures, and airflow and give you the report.

See a real example: a homeowner who went through six companies before we sized it right.

Questions We Get in Lewisville

How do I know if my Lewisville system is original?
Check the data plate on the outdoor unit for the manufacture date, or send us a photo of it. If the date is close to the year the house was built, it is the original system.

Can my R-22 system still be repaired?
It can be serviced with recovered or stockpiled R-22, but R-22 has not been produced or imported since January 1, 2020, so every recharge costs more. On an older system with a leak, replacement is usually the better money.

Do you replace the ductwork too?
Only if it needs it. We inspect and test the ducts on every replacement and tell you what we find. Many Lewisville homes need sealing or a few resized runs, not a full duct replacement.

How long does a replacement take?
Most homes are done in one day. Jobs that add duct work or a new furnace can take two.

Do you serve all of Lewisville?
Yes. We work across Lewisville (75057, 75067, and 75077), including Old Town Lewisville, Castle Hills, and the Lake Lewisville area.
