WHAT WE FIX
Heating Problems We Repair
Furnace Blowing Cold Air
Usually the burners aren’t lighting, so the fan is moving air that was never heated. Common causes are a worn-out igniter, a dirty flame sensor, or a gas valve problem. It can also happen when the furnace overheats: a safety switch shuts the burners off, but the fan keeps running to cool the furnace down, so you feel cool air.
Lights, Then Shuts Off
Often a dirty flame sensor. This small metal rod tells the furnace the flame is actually burning. When it gets coated with buildup, the furnace can’t confirm the flame and shuts the gas off within seconds as a safety measure, so unburned gas doesn’t build up. It’s one of the most common no-heat calls, and usually a quick repair.
Turns On and Off Constantly
This is called short cycling. A clogged filter, overheating, or a thermostat problem are frequent causes. It matters because starting up is the hardest part of a furnace’s job: every start heats and cools the metal parts and puts extra strain on the igniter and motors, so frequent starts wear the system out faster and waste fuel.
Blower Won’t Run or Won’t Stop
The blower is the fan that pushes warm air through your vents. If it won’t run, the cause can be the motor, the capacitor that helps the motor start, the control board, or the thermostat. If it won’t stop, check that the thermostat fan setting is on “Auto,” not “On”; if it is, a control or relay problem may be keeping it running.
Strange Noises or Smells
Banging, squealing, or a burning smell that doesn’t go away should be checked early. A bang at startup can mean gas is building up before it lights; squealing often points to a worn blower motor. Caught early, these are usually smaller repairs than when the part fails completely.
Not Enough Heat
Some rooms cold, or the house never reaches the set temperature? A dirty filter or closed vents can cut the airflow, leaky or poorly sized ductwork can lose heat before it reaches the room, and an aging system may simply not keep up anymore.
CHOOSING A COMPANY
How to Choose a Heating Repair Company
The best heating repair company for your home is one that’s licensed, upfront about price, and works on homes like yours. Before you hire anyone, ask these questions:
- Are you licensed in Texas? Heating and air conditioning contractors in Texas are licensed by the TDLR (Texas Department of Licensing and Regulation). A license means the contractor has met state requirements and carries required insurance, and it gives you a place to file a complaint if something goes wrong. You can look up any license number on the TDLR website. Ours is TACLB00076800E.
- What does the service call cost, and what does it include? Some companies charge a trip fee and then a separate diagnostic fee. Ours is $29 and includes the trip, the diagnosis, and small fixes.
- Will I get the full price before you start? With hourly billing, the price can grow while the technician works. We give you an exact flat-rate price before any work begins, so the price doesn’t change.
- Do you charge more for evenings or Saturdays? Many companies add overtime fees outside regular hours. We don’t charge overtime.
- Do you work on homes? Home systems and commercial rooftop systems are different equipment. We work on residential homes only.
- Are your reviews recent? Recent reviews show how the company is doing now, with its current technicians. Look for steady, recent reviews, not just a few old ones.

REPAIR OR REPLACE
Repair or Replace Your Furnace?
Most heating problems are repairs, not a reason to buy a new system. Gas furnaces often last around 15 to 20 years. Over time, years of heating up and cooling down wear on the metal parts, and older furnaces are generally less efficient than new ones, so they use more gas for the same heat. If yours is older and breaking down often, our technician will tell you honestly whether a repair still makes sense. When replacement is the better value, we’ll give you a free in-home estimate.
New installations include a 10-year parts warranty, extended labor warranties are available, and financing is available for new equipment and repairs over $500, with approved credit.
SAFETY FIRST
When It’s an Emergency
According to Atmos Energy, if you smell gas, leave the house right away. Once you’re safely away, call 911 and your gas company’s emergency line. For most homes with natural gas in our area, that’s Atmos Energy at 866-322-8667. Don’t flip light switches, use your phone inside, or try to relight the furnace — a tiny spark from a switch or electronics can ignite gas that has built up in the air.
If your carbon monoxide alarm goes off, get everyone outside and call 911. Carbon monoxide has no color or smell, so the alarm is the only warning you’ll get. A gas furnace can release it if the fuel isn’t burning cleanly, the exhaust is blocked, or the part that keeps exhaust separate from your home’s air (the heat exchanger) is cracked.
If you have gas heat and no carbon monoxide alarm, install one near the bedrooms, so it can wake you up at night.

I randomly looked up Texas Discount Air and filled up a form online for a quick diagnosis ( they had unbeatable rates for a service call $29 ).I received a SMS to confirm and schedule. Todd arrived on time, diagnosed and fixed the problem in a flash and even did not charge me coz it was a simple fix. WOW!!! Who does that anymore ?

ACs been running poorly, $500 electric bill was the final straw. Called Todd assuming freon was low. His equipment showed it was still full, so he did an inspection on the unit to find back coil covered in debris (forgot to clean!). At no charge, at the absolute minimum he is an honest man, which is everything today. Will use in future. Thank you, sir.
