Heat pump or furnace? That is the first thing that matters when the heat quits in Conroe, TX, because the two fail in completely different ways. Heat pumps tend to ice over when defrost stops working, get stuck in cooling when a reversing valve fails, or quietly lean on the electric backup strips, at several times the normal operating cost, when the outdoor unit dies. Gas furnaces usually come down to the flame sensor: once oxide coats it, the burners light but the flame cannot be proven, so the board cuts the gas and locks out after three tries. After that, we most often find cracked hot surface igniters, stuck pressure switches, clogged condensate traps on high-efficiency models, and blower motors at the end of their life.
Fault codes are where our diagnosis starts, not where it ends. On every no-heat call, Conroe HVAC confirms the board's story with measurements: flame signal read in microamps, igniter resistance checked, the pressure switch tested against real inducer draft, capacitors and motors metered, and, on heat pumps, refrigerant charge and defrost operation verified. Any visit that touches the gas side also covers the safety basics. We leak-test the connections, look over the heat exchanger, and confirm the flue is drafting, since a repair that has not been proven safe is not a finished repair.
We service gas and electric furnaces, heat pumps, air handlers, boilers, and ductless systems across all major brands, with igniters, flame sensors, capacitors, inducer motors, and blower motors stocked on the truck, so the majority of repairs finish in one trip. If your equipment is at the end of the road, we say so honestly and walk you through the options with real numbers.

Warning Signs for Heating Repair
The sooner you notice these red flags, the easier and cheaper the problem is to resolve. These are the signals our technicians see most often when a problem is underway:
- Higher heating bills with less comfort to show for them
- Thick ice or frost covering the heat pump outside
- The system starting and stopping every few minutes without warming the house
- A rotten-egg, burning, or musty smell once the heat kicks on
- A furnace that tries to light, clicks, and then quits
- Cold rooms in one part of the house while others are comfortable
- Banging at startup caused by burners lighting late
- No warm air at the registers even with the heat turned up
Don't Wait for a Total Failure
Left unchecked, even a small fault or temperature swing often signals a system working its way toward a breakdown. At the first hint of a problem, reach out to Conroe HVAC at (936) 209-8779 for a fast inspection.

Why Hire a Professional for Heating Repair?
Combustion is what makes heating repair different from the rest of home comfort work. A late light-off booms unburned gas inside the heat exchanger and stresses the metal each time it happens. A cracked exchanger can leak combustion gases into the air your family breathes, and a flue that stops drafting pushes carbon monoxide into the living space instead of outdoors. None of these problems make themselves obvious to someone without training and instruments. Diagnosis has its own traps as well. Short cycling can point to a failing limit switch or to a furnace protecting itself from a clogged filter, and a flame sensor cleaned without finding out why it fouled simply sets up the next lockout.
Instruments and judgment are what our experienced technicians bring to both sides of that problem. We measure the flame signal instead of assuming it, inspect the heat exchanger, verify draft at the flue, and check temperature rise against the data plate so blower speed and burner output are matched. With heat pumps, the defrost board, sensors, and reversing valve get tested before anyone condemns a compressor, and we look at whether the backup strips have been quietly inflating your bill for weeks. Each repair we complete is proven safe and correct over a full heating cycle, which is the standard you should expect from anyone working on the equipment that keeps your family warm.
Our Heating Repair Process
Every visit follows a step-by-step method refined over years of hands-on experience. Here's what you can expect when you choose Conroe HVAC:
Diagnosis & Safety Inspection
We pull the fault codes, then verify: flame signal, igniter resistance, pressure switch operation, motor and capacitor health, and charge and defrost on heat pumps, with gas connections leak-tested as standard.
Clear Findings & Upfront Quote
We show you what failed and why, and give a firm price before work begins. If a cracked heat exchanger or dead compressor changes the math toward replacement, we say so plainly.
Expert Repair
Igniters, flame sensors, pressure switches, capacitors, and motors ride on our trucks, so most heating repairs are completed the same visit and the house starts warming before we leave.
Final Testing
Before we leave, the system runs through full heating cycles while we measure temperature rise against the data plate, confirm safe combustion and venting on fuel-burning equipment, and check each safety control.
Maintenance Tips for Heating Repair
Taking preventive measures can help you avoid costly heating and cooling problems down the road. Follow these tips from our experienced technicians:
- Do not ignore a boom at ignition or a new rattle, since early repairs cost far less
- Keep chlorine products, paints, and solvents away from the furnace, because their fumes corrode burners
- Leave open space around the furnace so the burners can draw enough combustion air
- Install a CO detector on each floor and test them every month
- Book a fall tune-up so worn parts are caught before the first cold night
- Change the filter monthly in heating season; starved airflow trips limit switches and cracks exchangers early
- Clear snow, leaves, and overgrown shrubs from around the heat pump so defrost works properly
Should You DIY or Call a Pro?
A homeowner can swap a filter with ease, but diagnosing capacitors, refrigerant charge, control boards, and error codes calls for the equipment and know-how only a pro brings. Consider the following comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| CO Safety | No way to detect a CO problem | Exchanger inspected, flue draft confirmed |
| Troubleshooting | Error code guessing games | Readings taken before parts are replaced |
| Gas Safety | A loose fitting goes unnoticed | Every joint checked with a leak detector |
| Heat Pumps | Defrost problems misread as total failure | Each defrost component checked in turn |
| Root Cause | Sensor cleaned, cause ignored | The fault behind the fault diagnosed |
| Verification | It lit once, good enough | Temperature rise measured over full cycles |
