When a furnace stops producing heat or runs but never reaches the set temperature, our technicians test the igniter, flame sensor, gas valve, and control board to find the exact fault. We carry common replacement parts on every truck so our furnace repair service can handle most jobs in a single visit.
Gas furnaces require precise attention to the burner assembly, heat exchanger, and gas pressure. Every gas furnace repair service call includes a full inspection of the combustion and venting system to make sure the job is safe, complete, and tested under full load before we leave.
Electric furnaces rely on heating elements, sequencers, and high-voltage connections. Our technicians test element resistance, check sequencer operation, and verify wiring to identify the exact failure. Most homeowners who schedule an electric furnace repair service with us have the problem solved the same day.
Heat pumps operate in both heating and cooling modes, so a failure can affect year-round comfort. A heat pump repair service call with our team covers the reversing valve, defrost cycle, refrigerant charge, and both indoor and outdoor coils to find and fix the problem in one trip.
When the heat goes out during a cold snap, waiting is not an option. We offer same-day dispatch across Houston, and every emergency heating repair service call is treated as a priority. Our team arrives with the parts and tools needed to diagnose and fix the most common heating failures on the spot.

When you need heating repair and maintenance in Houston, 75 Degree AC brings the right experience to every call.
Our contractors are fully licensed and insured. We have been working on Houston heating systems for years, and every repair is backed by full insurance coverage and a quality workmanship guarantee.
Urgent heating calls get same-day dispatch across Houston. Common parts like igniters, flame sensors, and gas valves are stocked on our trucks. Most repairs are completed in a single visit without needing to order parts and return.
The cause is found and explained before any repair starts. The price is locked before work begins and does not change once the job is underway. When replacement makes more financial sense than a repair, that is explained clearly with the reasoning behind it.
Our contractors work on gas furnaces, electric furnaces, heat pumps, and air handlers. That full range means a faster, more accurate diagnosis on any heating system in any Houston home, regardless of brand or age.
Call (713) 598-2737 to schedule heating repair and maintenance with 75 Degree AC. Same-day appointments are available across the Houston metro. Free estimates are provided for replacement recommendations.
75 Degree AC follows the same diagnostic and repair process on every heating repair and maintenance call, from the first phone call to the final performance check.
Book online or give us a call to schedule service. Same-day availability is offered for urgent heating failures. Let us know what the system is doing and when the problem started. That information helps get the right parts on the truck before arrival.
On arrival, our contractors check voltage, test motor current draw, measure gas pressure, inspect the heat exchanger for cracks, and run a carbon monoxide check. On heat pump systems, both heating and cooling modes are tested. The goal is a complete picture of the system before any repair recommendation is made.
The cause of the failure is explained in plain terms. The full repair price is given before any work starts, and it does not change once the job is underway. No work begins without the homeowner agreeing to the cost first.
The failed component is replaced with a part matched to the system. Our trucks carry inventory that covers the major brands we service across Houston for most common parts. Less common components are sourced quickly to keep delays short.
After the repair, the system runs through a full heating cycle under load. Temperature rise across the heat exchanger is measured and the system is left running until it reaches the set temperature. The repair is confirmed working before the contractor leaves.
A gas furnace heats your home by burning fuel in a burner assembly and using a blower motor to push air across the heat exchanger. The heat exchanger transfers heat from the combustion gases to the air moving through the duct system. Supply vents push hot air into each room while return vents pull cooler air back to be reheated. Safety switches, the control board, and the thermostat work together to run and stop each cycle. When a component in that chain fails, 75 Degree AC diagnoses the heating repair by testing each part in sequence.
A heat pump moves heat instead of generating it. In heating mode, the reversing valve directs refrigerant so the outdoor coil absorbs heat from the air and the indoor coil releases it into the home. Houston’s mild winters make heat pumps an efficient choice for most of the heating season. When outdoor temperatures drop below freezing, the system runs a defrost cycle to keep the outdoor coil operating.
75 Degree AC provides premium HVAC services across Houston, TX, supporting residential and light commercial properties throughout the city. Our service coverage reflects how HVAC demand actually works in Houston, from central neighborhoods to outer city districts. Customers rely on us for consistent service standards, clear communication, and dependable system support city-wide.
Houston, TX is not known for severe winters, but the cold events that do hit the city cause a spike in heating failures every season. The winter storm that dropped overnight lows into single digits knocked out heating in thousands of homes across the metro. Even in a typical year, a few cold snaps drive overnight temperatures well below comfortable levels, and systems that sat idle for most of the year face heavy demand for the first time all season. That shift from months of inactivity to full-load heating is when aging components fail most often.
Humidity plays a role too. Houston’s hot and humid climate speeds up corrosion on heat exchangers, flue pipes, and ductwork. Homeowners in Midtown, Montrose, The Heights, and other older neighborhoods often have systems and ductwork that have been in service for well over a decade. That age, combined with Houston’s climate conditions, means heating maintenance is not optional for those homes. Homeowners in Sugar Land, Katy, and the suburbs tend to have newer equipment but face the same short, intense heating seasons. Regular inspection before cold weather arrives is the best way to keep any heating system ready when it is needed most.
