What Customers Say About Our Service
How 75 Degree AC Handles Heating Repair Differently in Houston
When you need heating repair and maintenance in Houston, 75 Degree AC brings the right experience to every call.
Same-Day Service
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.
Honest Diagnosis First
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.
All Systems Covered
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.

How We Handle Your Heating Repair in Houston
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.
Schedule Your Visit
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.
Full System Check
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.
Diagnosis and Price Lock
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.
Repair With Right Parts
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.
Test and Confirm Heat
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.

How Gas Furnaces and Heat Pumps Heat Your Houston Home
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.

Frequently Asked Questions FAQ's
Why Is My Furnace Running But Not Producing Any Heat in My Houston Home?
The most common causes are a failed hot surface igniter, a dirty flame sensor, or a burner not lighting consistently. The furnace turns on and the blower runs, but no heat comes through the vents. Our contractors test each component in order to find the exact cause before replacing anything.
How Often Should a Houston Home Heating System Be Inspected and Serviced?
Once per year is the standard recommendation, with fall being the ideal time before cold weather arrives. Systems in older Houston homes or those with prior repair history benefit from service twice per year. Regular service catches worn igniters, dirty sensors, and low gas pressure before they cause a no-heat failure.
What Are the Most Common Signs a Gas Furnace Needs Professional Repair?
Short cycling, a yellow or orange burner flame, banging sounds on startup, and energy bills rising with no change in usage are the signs our contractors see most often on Houston service calls. Any one of these points to a specific fault that needs to be tested and confirmed, not just monitored.
Can a Heating System Be Diagnosed and Repaired on the Same Day in Houston?
Yes, for most common failures. Our contractors carry igniters, flame sensors, capacitors, and gas valves on the truck. Diagnosis takes less than an hour, and most repairs are completed in the same visit. Parts that are not stocked are sourced quickly to keep downtime short.
What Does a Professional Heating Maintenance Visit in Houston Actually Include?
A maintenance visit covers filter replacement, burner inspection, igniter testing, flame sensor cleaning, heat exchanger check for cracks, motor current draw test, gas pressure test, and a carbon monoxide check. The goal is to catch worn parts before they cause a cold-weather failure.
When Should a Houston Homeowner Repair a Heating System Instead of Replacing It?
When a system is relatively new and the repair cost is well under the cost of a new unit, repair is almost always the right call. For older systems with repeated repairs and rising energy bills, replacement often makes more financial sense. Our contractors give both options with clear pricing so the homeowner can decide.
About Houston, TX
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.
