AC Repair in Colleyville for Big Homes and Big Attics

Colleyville's homes are big. Brook Meadows houses average around 4,200 square feet, and many in Montclair Parc and Oakbrook Hills top 5,000 or even 6,000. Homes that size usually rely on two or more air conditioners and long runs of attic ductwork, so AC repair in Colleyville often means sorting out which system is failing and why one floor runs warmer than another.

HAT Plumbing, Heating & Air is based on Pebble Drive in northeast Fort Worth not far from Colleyville. We diagnose, maintain and replace cooling and heating equipment throughout the city.

Upstairs too warm? Get in touch or call (817) 405-4575 and we will send a licensed HVAC technician.

AC Repair, Heating & HVAC Services in Colleyville

Here is how our services match Colleyville homes:

  • AC repair: troubleshooting each system in multi-unit homes when one zone stops keeping up.
  • AC replacement: installs that follow the city's HVAC Replacement Guidelines, with virtual inspection available.
  • AC maintenance: spring tune-ups for every unit on the property, not just the downstairs one.
  • Ductless mini-splits: cooling for bonus rooms, pool houses and garage workshops on large lots.
  • Heating repair: gas furnace and heat pump fixes when temperatures drop.
  • Furnace installation: Atmos Energy gas furnaces matched to the home's layout.
  • Heating maintenance: flue, burner and safety checks before winter.

With several systems per house, small problems multiply, so we look at the whole setup on each visit. Also need a plumber? Visit our Colleyville plumber page or see all HVAC services.

Colleyville Climate, Utilities and Permits

  • Oncor or Tri-County Electric: the city's utilities page lists both Oncor and Tri-County Electric Cooperative, so your electric service depends on your address. In Oncor areas you shop for a retail provider; co-op members buy from Tri-County directly.
  • Atmos Energy for gas heat: Atmos supplies natural gas in Colleyville, and gas furnaces paired with central AC are a common setup in homes from the 1980s and 1990s.
  • HVAC Replacement Guidelines: Colleyville's Building Inspections Department publishes replacement guidelines and offers virtual inspections for HVAC change-outs. Its checklist calls for duct and plenum connections sealed with approved mastic or tape, which we follow on every install.
  • Registered contractors only: the city requires contractors to register before permits are issued, so ask any HVAC company whether it is registered in Colleyville.
  • February 2021 outages: many residents went days without power during the February 15 to 19 storm, and the city ran a warming center at City Hall and the Library until power returned. A furnace and heat pump checked each fall stands a better chance in the next deep freeze.

Older houses built as the city grew from the 1970s through the 1990s often still have original ductwork in hot attics, even when the equipment has been swapped. Leaky or poorly sealed ducts waste cooling, so we inspect them whenever we replace a unit.

Heating and Cooling in Colleyville Neighborhoods

We serve homes on both sides of Colleyville Blvd, near City Park on Bransford Rd, Bransford Park and the Cotton Belt Trail:

  • Montclair Parc: guard-gated homes of 5,000 to 6,500 square feet or more, typically running multiple systems that benefit from coordinated maintenance.
  • Oakbrook Hills: large two-story custom homes from 1997 to 1999 in northwest Colleyville, where upstairs zones often work hardest in summer.
  • Brook Meadows: homes finished by 1994, many now on replacement equipment and ready for duct evaluation.
  • Tara Plantation: 1980s colonial homes on half-acre lots, where furnace and AC age make replacement planning worthwhile.
  • Saddlebrook Addition: late 1980s single-family homes whose attic ductwork may date to original construction.
  • Oak Alley: custom infill homes from around 2020, where maintenance protects newer high efficiency equipment.
  • Ross Downs Estates: roughly 320 custom executive homes off Pool Rd, many 1990s houses on mature lots where shade trees drop debris onto outdoor units.

Across these subdivisions, the pattern repeats: plenty of square footage, several systems per home and ductwork that has been in the attic for decades. Planning replacements one unit at a time, with the oldest first, keeps costs manageable and avoids surprise failures in August.

“I’ve been pleased with HAT’s service. Most recently we had a thermostat go bad and turns out it was no longer made. We thought it was going to be an expensive fix — it took an extra day but HAT found a solution that wasn’t going to cost an arm and leg. Thank you! No pressure — just a solution.”

Frequently Asked Questions

Does Colleyville require a permit to replace an air conditioner?
Yes. Colleyville publishes HVAC Replacement Guidelines, and replacements must be permitted by a contractor registered with the city. The Building Inspections Department offers virtual inspections for HVAC change-outs, and its checklist requires duct and plenum connections sealed with approved mastic or tape. We handle the permit, the install and the inspection so everything is documented.
Why is my upstairs hotter than downstairs in my Colleyville home?
Many Colleyville homes are large two-story houses with separate systems for each floor. Heat rises, the upstairs unit fights a hot attic, and long duct runs lose cooling along the way. A weak upstairs system, leaky ducts or poor return airflow are common causes. We test each system and the ductwork to find which one is responsible.
Who provides electricity in Colleyville, Oncor or Tri-County?
Both serve parts of Colleyville, according to the city's utilities page, so it depends on where you live. Check your electric bill to see which applies. Oncor customers choose a retail electric provider, while Tri-County Electric Cooperative members buy power from the co-op. Either way, more efficient equipment lowers the power used to cool a large home.
How can I protect my Colleyville heating system before a hard freeze?
February 2021 left many Colleyville residents without power for days. Schedule heating maintenance in the fall so burners, flues, igniters and heat pump defrost controls are checked before cold weather. Replace filters, keep outdoor heat pump units clear, and know where your gas shutoff is. A system in good shape is more likely to run when power comes back.
