What customers say about furnace repair
…Even offered for someone to call and set up an emergency service that night. Not necessary yet. Got a call first thing Thursday morning that someone could be to my house by 10am that morning look at it. Mekonnen Taddese showed up right on time. Within no time he identified my 30yrs old furnace had a bad circuit board and would be 1/2 the cost of a new unit if they could even source the board. Now remember that a huge arctic front is coming and will be here Friday night and I have no heat in my house. I said “Let’s do it if you have it in stock”…

What customers say about furnace repair
Samm's has been servicing my HVAC for years and, since they've started working on it, it has been performing perfectly. I found Samms after several other companies couldn't seem to figure out an issue with the furnace. I now have a maintenance plan with them and while my older system has needed a few tiny repairs and tweaks - nothing major - over the years and their pricing is fair and the techs are friendly and seem very honest. Have recommended them to several friends and they've all had the same experience.

What customers say about furnace repair
Our HVAC technician came out late at night when our family had no heat, and we are so grateful for his help. He quickly diagnosed the issue, explained everything clearly, and gave us solid recommendations for the next steps. Most importantly, he made sure we had temporary heat so we could stay warm and safe overnight. His professionalism, kindness, and dedication to his customers truly stand out. Great service and a great business. I would absolutely recommend them to anyone!

What Every Plano Resident Should Know Before Scheduling Service
- 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.
- What are the mandatory HVAC licensing requirements for contractors in Plano, TX?
- All HVAC contractors operating in Plano must hold a valid license issued by the Texas Department of Licensing and Regulation (TDLR). This state-mandated certification ensures that technicians have completed required training and adhere to safety protocols. When hiring, you should always request the technician's license number to verify their standing through the official TDLR database before allowing any work on your property.
- How can I find a reliable 24/7 emergency HVAC service in Plano?
- Look for providers who explicitly advertise 24/7 emergency support and maintain a local presence in neighborhoods like Willow Bend or Legacy. Reliable companies typically provide clear communication regarding their after-hours dispatch process and response time expectations. Checking recent customer feedback for mentions of timely weekend or late-night repairs can help identify which local firms prioritize urgent service calls during extreme weather events.
- Typical HVAC pricing in Plano, TX: what should I budget?
