Complete HVAC Services in Grapevine & DFW
A licensed HVAC contractor serving Grapevine and the Mid-Cities. HVAC repair, installation, heating, maintenance, ductwork, air quality and commercial HVAC — with upfront pricing after diagnostics.
A Licensed HVAC Contractor Based in Grapevine, TX
Too Cool Air is a licensed Texas HVAC contractor (TACLB50985E) operating from 410 E Northwest Hwy #10, Grapevine, TX 76051. Every service on this page is delivered by the same Grapevine-based company that diagnoses the system, so the people who take the measurements are the people who stand behind the work.
We provide HVAC service in Grapevine and throughout the surrounding DFW Mid-Cities, including Grapevine, Southlake, Colleyville, Coppell, Flower Mound, Keller, Haslet, Double Oak, Bartonville, Lantana and the neighboring communities listed on our service areas page.
Heating and cooling services here begin with diagnostic measurements — airflow, static pressure, temperature split, humidity and refrigerant condition — before any repair or replacement is recommended. That is the basis of the Too Cool Air Diagnostic System and the $89 Comfort Audit.
You can schedule HVAC repair, installation and replacement, seasonal maintenance, airflow testing, ductwork correction, indoor air quality and humidity work, or light-commercial HVAC service. Appointments are booked by availability — use the booking link below or call (214) 437-7886.
HVAC Repair & Diagnostics
HVAC repair that starts with measurement — airflow, static pressure, temperature split and refrigerant verification before any part is quoted.
HVAC repair in Grapevine starts with measurement rather than part-swapping. Before anything is quoted, the system is tested under real operating conditions so the repair addresses the cause of the complaint instead of the first symptom that shows up at the thermostat.
What customers describe
- The air conditioner runs constantly but the house never reaches the setpoint
- The system short-cycles, trips a breaker or freezes at the indoor coil
- A previous company recommended a large repair without showing any readings
What Too Cool Air evaluates
- Temperature split, airflow and static pressure across the equipment
- Refrigerant condition, electrical components and safety controls
- Indoor humidity and how the ducts and home are affecting the equipment
HVAC Installation & Replacement
System replacement designed around a Manual J load calculation and your existing ductwork — not square-footage rules of thumb.
Replacement work is designed around a Manual J load calculation and the duct system that already exists in the home. Equipment selection, airflow requirements and cabinet fit are confirmed first, because new equipment installed onto an undersized duct system inherits the same comfort problem.
What customers describe
- Repeated repairs on equipment that is near the end of its service life
- A system that was replaced recently and still leaves rooms uncomfortable
- Uncertainty about sizing after receiving quotes based on square footage alone
What Too Cool Air evaluates
- Room-by-room load calculation, not a rule-of-thumb tonnage estimate
- Existing duct capacity, return air and equipment airflow requirements
- Electrical, drainage, venting and clearance conditions at the install location
Furnace & Heating Services
Furnace replacement, heat pumps and dual-fuel systems sized, vented and verified for North Texas winters.
Heating work in North Texas covers gas furnaces, heat pumps and dual-fuel systems. Combustion, venting and safety testing are part of the evaluation, along with the airflow the heating equipment actually receives once the ducts and filter are accounted for.
What customers describe
- The furnace shuts down on its own or produces uneven heat between floors
- A burning or unusual odor when the heat first runs for the season
- A heat pump that struggles on the coldest mornings of the year
What Too Cool Air evaluates
- Combustion performance, venting condition and safety-control operation
- Temperature rise compared with the manufacturer's published range
- Heat-pump staging, auxiliary heat behavior and control settings
Commercial HVAC
Light-commercial diagnostics, rooftop and split-system service, preventive maintenance and documented readings for offices, retail, restaurants and convenience stores.
Light-commercial HVAC service covers rooftop package units, split systems and mini-splits at offices, retail bays, restaurants and convenience stores. Readings are documented so a property manager or owner has a service record to compare against next season.
What customers describe
- A rooftop unit that cannot keep up during business hours
- Uneven conditions between a dining room, kitchen or sales floor
- No documented maintenance history across multiple units on one roof
What Too Cool Air evaluates
- Unit-by-unit airflow, static pressure and temperature performance
- Economizer, ventilation and control operation where equipped
- Filter condition, coil condition and drainage on each system
Ductwork & Airflow
Most comfort complaints are airflow problems. These services measure and correct static pressure, leakage and duct sizing.
A large share of comfort complaints are airflow problems rather than equipment problems. Duct sizing, leakage, return capacity and filter resistance are measured so the correction is targeted at the restriction instead of the thermostat.
What customers describe
- One room or the upstairs level stays warmer than the rest of the house
- Weak air at the registers even though the blower is running
- Noisy returns, whistling grilles or dust returning quickly after cleaning
What Too Cool Air evaluates
- Total external static pressure and pressure drop across components
- Duct sizing, layout, connections and return-air capacity
- Leakage locations, insulation condition and register delivery
Indoor Air Quality & Humidity
Filtration, humidity control and ventilation recommended only when the measurements show they will help.
Filtration, humidity control and ventilation are recommended only when the measurements show they will help, and only when the equipment and duct system can carry the added resistance. Air quality work is designed as part of the installed system rather than an add-on product.
What customers describe
- The home feels damp or clammy even while the air conditioner is running
- Dust, odors or stuffiness that returns shortly after filters are changed
- Concern about filtration after a high-efficiency filter was installed
What Too Cool Air evaluates
- Indoor humidity, temperature and runtime under normal operation
- Filter pressure drop, filter fit and bypass around the filter rack
- Ventilation, moisture sources and how the duct system is distributing air
HVAC Maintenance & Tune-Ups
Documented preventive service with readings and photos — not a checklist with everything circled “good.”
Preventive service is documented with readings and photos so each visit can be compared with the last one. The purpose is to catch drift in airflow, refrigerant condition or electrical components before it turns into a failure in the middle of a Texas summer.
What customers describe
- No record of what was measured during previous maintenance visits
- Rising utility bills without any obvious change in how the system runs
- Filters that are forgotten between seasons
What Too Cool Air evaluates
- Airflow, static pressure, temperature split and refrigerant condition
- Electrical readings on the components that commonly fail
- Drainage, coil condition, filter fit and control operation
Specialty Systems & Controls
Ductless zoning, thermostats and control strategies for additions, garages and rooms a central system never reached.
Specialty work covers ductless zoning, thermostats and control strategies for spaces a central system was never designed to reach, such as additions, garages, bonus rooms and converted attics. Placement, sizing and control strategy are decided from the load on that space.
What customers describe
- An addition, garage or bonus room that no duct run reaches properly
- A thermostat or zoning setup that fights the equipment it controls
- A mini-split that was installed without a load calculation
What Too Cool Air evaluates
- Load and heat gain for the specific room or zone
- Line-set routing, drainage and indoor unit placement
- Thermostat compatibility, staging and control programming
