Air Conditioning Installation, Repair, and Maintenance in Farmers Branch
Quigley Heating & Air diagnoses, repairs, and replaces central air conditioning systems for Farmers Branch homes, and handles seasonal maintenance to catch small problems before they turn into breakdowns. We look at the whole system, including the outdoor unit, indoor coil, refrigerant lines, thermostat, and ductwork, then explain whether a repair or a replacement makes more sense.
The first long stretch of Texas heat is a bad time to learn a unit is on its last season. If your system is older and the repairs are stacking up, we walk through both paths before you decide.
Air Duct Repair, Sealing, and Installation in Farmers Branch
Your ductwork carries the air your system works to heat or cool, so leaky or damaged ducts and loose connections waste that effort. Quigley Heating & Air repairs, seals, replaces, and installs air ducts for Farmers Branch properties.
Many Farmers Branch homes sit on mature, tree-lined streets and have been renovated or added onto over the years. When a room has been added or a layout has changed, we check the duct system against how the house is used today.
Commercial HVAC Services in Farmers Branch
Farmers Branch is a business city, with offices, warehouses, and retail along I-35E, I-635, and the Dallas North Tollway. Quigley Heating & Air provides commercial HVAC installation, replacement, repair, and maintenance for those properties and for the light commercial buildings between them.
A rooftop unit that fails on a workday affects employees, tenants, and customers at the same time. We plan service around the building and the schedule, not just the equipment.
Duct Cleaning in Farmers Branch
Quigley Heating & Air offers professional duct cleaning that clears accumulated dust and debris from supply and return ducts and vents.
It is worth considering after a renovation, after moving into a previously owned home, or when you can see buildup around your registers.
Ductless Mini Split Systems in Farmers Branch
A ductless mini split heats and cools a single room or zone without ductwork. Quigley Heating & Air installs, repairs, replaces, and maintains these systems for finished garages, room additions, sunrooms, and offices where extending ducts is not practical.
If you are finishing a garage or adding a room in Farmers Branch, a mini split is often simpler than stretching the home’s existing ductwork.
Furnace Installation, Repair, and Maintenance in Farmers Branch
Quigley Heating & Air repairs, maintains, and installs gas furnaces for Farmers Branch homes. A visit covers the ignition, blower, heat exchanger, and safety controls, and we explain what we find in plain language.
Cold snaps in North Texas tend to arrive with little warning. A fall check on the furnace is easier than a repair call on the coldest night of the week.
Heat Pump Installation, Repair, and Maintenance in Farmers Branch
A heat pump heats and cools from one system, which makes it a common option when an older air conditioner and furnace are both near the end of their lives.

HVAC Maintenance Plans in Farmers Branch
The Q Club Preventative Maintenance Program includes regular inspections and tune-ups for your heating and cooling equipment, so problems are more likely to be found on a planned visit than in the middle of a heat wave. Ask us what the current plan includes and how it fits your system.

Farmers Branch HVAC FAQs
Does Quigley Heating & Air provide HVAC service in Farmers Branch, TX?
Yes. Quigley Heating & Air is headquartered at 13720 Diplomat Drive in Farmers Branch and provides heating, cooling, duct, and indoor air quality services for homes and businesses throughout the city.
Should I repair or replace my air conditioner?
Repair usually makes sense when one part has failed on a system that has otherwise been reliable. Replacement is worth discussing when the system is older, repairs are frequent, or a major component such as the compressor fails. A technician can inspect the unit and explain both options for your home before you commit to either.
Why does my Farmers Branch home feel humid or stuffy even when the AC is running?
Several things can cause it, including airflow problems, duct leaks, a system that is the wrong size for the space, or a coil or refrigerant issue. They look alike from the thermostat, so a technician needs to inspect the system to find the real cause. A whole-house dehumidifier is one option if humidity stays high after the basics are checked.
Is a heat pump or a gas furnace better for my home?
Neither is better for every home. A heat pump heats and cools from one system, while a gas furnace paired with an air conditioner uses separate equipment for each season. A dual-fuel system combines a heat pump with a gas furnace. Quigley Heating & Air can compare the options based on your home’s layout, current equipment, and budget.
How long has Quigley Heating & Air served Farmers Branch, and who owns it?
Quigley Heating & Air has been family-owned since 1945, when World War II veteran Sheldon F. Quigley started the company. Three generations have run it since, and Brandon Quigley leads it today from our headquarters at 13720 Diplomat Drive in Farmers Branch.
Is Quigley Heating & Air a licensed HVAC contractor in Texas?
Yes. The company holds Texas HVAC license TACLA23686E, which is also displayed on our website, and our technicians are NATE-certified.

What does an HVAC maintenance visit cover?
A maintenance visit generally includes inspecting the equipment, checking electrical connections and controls, cleaning key components, and testing that the system heats or cools as it should. The exact checklist depends on the type of system, so ask Quigley Heating & Air what is included for your equipment.
