What Customers Say

Rated 5.0 on Google.

26 Google reviews, 5.0 average, every one from a real DFW job. Here is a recent one, unedited.

“Henry helped me today, and I couldn’t be happier with the service! He was quick to respond, professional, and took the time to explain the root cause of the issue. What I really appreciated was that he educated me on how to prevent the problem in the future rather than simply trying to sell me products or an annual membership. It’s refreshing to come across someone who genuinely focuses on helping the customer. I would highly recommend Henry to anyone looking for a reliable, honest, and professional technician.”

New GREE FLEXX Ultra inverter outdoor unit installed on a leveled pad in Burleson, TX
Recent Install

Six companies couldn't fix it. A Manual J did.

A 4-year-old oversized system that never cooled the house. We had an independent company run Manual J, S, and D, then installed a right-sized GREE FLEXX Ultra inverter system and cleaned up the previous install in one day.

"I went through 6 and all were wrong... Without doing a Manual J, you wont get the right answers. Henry is the only one to recommend that."

Recent Commercial Project

Fuel Station Data Hut HVAC, Built for a GC

LG ductless condenser wall-mounted on a new fuel station data hut in Texas, with the fuel canopy behind it

New fuel station for a national retailer. The data hut runs the tank monitoring, pump controllers, and emergency panels, so it needs cooling every hour the pumps are open. We installed an LG ductless heat pump with a wall-mounted outdoor unit and a 4-way ceiling cassette, coordinated with the GC on an active site.

HVAC stands for heating, ventilation, and air conditioning, the equipment that heats, cools, and moves the air through your home or building. Whether you need a one-time repair, a full system replacement, or a maintenance plan, the sections below explain what we do, where we work, and how to decide your next step.

Every Comfort Mechanical Solutions client gets the data, documentation, and reporting that traditional HVAC contractors do not provide. That is the difference.

HVAC Questions, Answered

Frequently Asked Questions About HVAC Service in North Dallas.

Straight answers for homeowners, property managers, and light-commercial owners across North DFW.

How much does AC repair cost in North Dallas?

Short answer: it depends on the failed part, refrigerant type, and system age, and you get a firm quote before any work begins. The biggest cost factors are the component involved (a capacitor costs far less than a compressor), whether your system uses phased-out R-22 refrigerant, how accessible the equipment is, and after-hours timing. We diagnose first, explain your options in plain language, and never start repairs without your approval.

Should I repair or replace my AC unit?

Short answer: repair is usually right for systems under 10 years old with a single failed component; replacement usually wins for systems 12-15+ years old with major failures. Replacement makes sense when:

  • The compressor or heat exchanger has failed and the unit is out of warranty
  • Your system uses R-22 refrigerant, which is no longer produced
  • Repair costs approach half the price of a new system
  • Energy bills keep climbing despite regular maintenance

Repair makes sense when the system is under about 10 years old, the failure is a common part (capacitor, contactor, fan motor, thermostat), and the rest of the system checks out during diagnostics. We show you the readings from your own equipment and walk through both options, the decision is always yours.

How fast can you get to my home or property?

Short answer: we offer 24/7 emergency HVAC service across North DFW, and most residential calls are scheduled same-day or next-day. Call (469) 213-8450 any time, nights, weekends, and holidays included.

What is included in an HVAC maintenance visit?

Short answer: a full inspection, cleaning, and documented performance readings for your system. A typical visit includes:

  1. Refrigerant pressure and temperature-split readings
  2. Electrical testing of capacitors, contactors, and motors
  3. Coil and drain-line inspection and cleaning
  4. Airflow and ductwork check
  5. Thermostat calibration
  6. A written report with photos and measurements, documentation most contractors do not provide

How do I verify an HVAC contractor is licensed in Texas?

Short answer: look up their license number on the Texas Department of Licensing and Regulation (TDLR) license search. Every legitimate Texas HVAC contractor holds a TACL license, ours is #TACLA00165496E. Always confirm licensing and insurance before letting anyone work on your system.

Do you service commercial and multifamily properties?

Short answer: yes, light commercial and multifamily HVAC is a core part of our business, including rooftop units, make-up air, PTAC and vertical stack units, and scheduled maintenance programs with per-unit documentation for property managers.
