What customers say about furnace repair
I can’t say enough great things about DallasHVAC. I needed a control board for my York furnace, and of course the issue happened on a Sunday when most places were closed. Glen and Adam went above and beyond to make sure I got the correct part quickly and without any hassle. When I later ran into issues with technicians trying to diagnose the problem, Adam didn’t just sell me a part and move on—he referred me to a technician who was able to figure out what four other technicians couldn’t. That level of support and partnership is rare…
We bought absolutely nothing! During a big storm, our heat stopped working. He could of sold us a part we thought we needed but did not. He chose a path of honesty and helpfulness instead. Our heat is back on, no part needed ! But if we ever have a challenge again, their honestly and customer service will make them our first call.

What Every Garland Resident Should Ask Before Booking an HVAC Dispatch
- When is a furnace problem an actual emergency vs. a next-day call?
- Carbon-monoxide alarm, smell of gas, or visible cracks in the heat exchanger → emergency. No-heat in sub-freezing weather is urgent but rarely safety-critical. Most no-heat calls are igniter, flame sensor, or gas valve — same-day fixable.
- What's the difference between a flame-sensor clean ($120) and heat-exchanger replacement ($1,500+)?
- Flame sensors clog with combustion residue and stop signaling the gas valve — quick clean or swap. Cracked heat exchangers leak CO into your home airflow and require exchanger replacement (often impractical) or full furnace replacement. The tech's CO meter reading decides which one you're facing.
- Is a city-issued permit required for HVAC system replacements in Garland?
- Yes, the city requires a mechanical permit for most major HVAC system replacements to ensure the work meets current safety standards. Texas Department of Licensing and Regulation (TDLR) rules mandate that only state-licensed technicians perform this work. Homeowners should verify that their chosen contractor handles the permit application process and subsequent inspections, as this is a standard requirement for all residential cooling and heating installations within Garland city limits.
- When does HVAC service demand peak in Garland?
- Demand for HVAC services in Garland typically spikes during the intense summer months when temperatures consistently exceed 95 degrees. During these peak periods, scheduling routine maintenance becomes more difficult, and response times for non-emergency repairs may increase. Many residents in neighborhoods like Oakridge or Duck Creek choose to schedule their system tune-ups in early spring to ensure their units are operational before the extreme heat arrives.
- How do I verify an HVAC contractor's credentials in Texas?
- You should confirm that the contractor holds a current Texas HVAC license, which is required by the Texas Occupations Code. You can verify this status through the Texas Department of Licensing and Regulation (TDLR) online portal using the company’s license number. Additionally, ensure the provider is properly bonded and insured, as these protections are essential for safeguarding your property during complex installations or major system repairs in Garland homes.
- What does HVAC service typically run in Garland, TX?
- Furnace repair typically runs $135–$775, and heat exchanger replacement runs $1,350–$3,200 in Garland, Texas. See the HVAC pricing table on this page for the full per-service breakdown.
