Signs You Need Heating Repair
- Your furnace is blowing cold or lukewarm air — this could be a pilot light issue, a failed ignitor, a bad gas valve, or a malfunctioning heat exchanger.
- You smell gas, rotten eggs, or a burning odor when your heater runs — turn off the system immediately and call for emergency service, as this could indicate a gas leak or electrical problem.
- Your heater makes loud banging, popping, or rattling sounds on startup — delayed ignition, loose components, or a cracked heat exchanger can cause these alarming noises.
- The system cycles on and off every few minutes without warming the house — short cycling wastes energy and often indicates a clogged filter, faulty flame sensor, or overheating issue.
- Your carbon monoxide detector has gone off while the heater is running — this is an emergency. Evacuate and call us immediately, as a cracked heat exchanger can leak deadly CO into your home.
Our Heating Repair Process
Call (469) 254-0548 — for safety-related heating issues (gas smell, CO alarm), we prioritize same-day emergency dispatch.
Our technician performs a comprehensive heating system inspection: checking the ignition system, heat exchanger integrity, gas connections, blower motor operation, and thermostat communication.
We identify the issue and explain it clearly. For safety-critical problems like heat exchanger cracks, we show you the evidence and explain the implications so you understand the urgency.
With your approval, we repair the system using quality parts. Most heating repairs are completed in a single visit within 1–3 hours.
After repair, we test the complete heating cycle: ignition, flame sensing, heat output, blower activation, thermostat response, and safety shutdown — ensuring your system is safe and effective.

Why Choose Frosty's for Heating Repair
Heating repair is not just about comfort — it's about safety. Gas furnaces involve combustion, gas lines, and the potential for carbon monoxide exposure if something goes wrong. Frosty's HVAC takes heating safety seriously. Our technicians are trained to inspect heat exchangers for cracks, test gas connections for leaks, and verify carbon monoxide levels in your home after every repair. We don't cut corners on safety inspections, even if you called for a simple thermostat issue.
Texas winters are unpredictable. One week it's 70°F, the next it's 25°F with ice on the roads. Your heater needs to work reliably when those cold fronts hit, and that means having a trusted technician who knows your system. Many of our heating repair customers are Frosty Club members who get priority scheduling — when temperatures drop and everyone is calling for heat, our members go to the front of the line.
We service all residential heating systems: gas furnaces, electric furnaces, and heat pumps. Our technicians carry common heating repair parts including ignitors, flame sensors, capacitors, and blower motors, so most repairs are completed on the first visit. All heating repairs include a 90-day warranty on parts and labor, and we follow up to make sure everything is still running when the next cold front arrives.
