When your heater needs a closer look

Understand the issue before making a decision.

  • No heat
  • Uneven heating
  • Frequent starting and stopping
  • Unusual sounds
  • Unexpected shutdowns
  • Air that never reaches the temperature you selected

Heating problems can involve controls, airflow, electrical components, or other equipment issues. A proper evaluation helps determine the cause and the appropriate repair or replacement considerations.

Some heating concerns need immediate attention.

If you smell gas, suspect carbon monoxide, or have an activated carbon monoxide alarm, leave the affected area and contact the appropriate gas utility or emergency service. Please don’t use the website form as your response to an immediate safety emergency.

Common Heating Problems We Can Diagnose

Heater Not Heating

Your system runs, but the air coming out isn’t warm.

Heater Won’t Turn On

Your system isn’t starting or responding normally.

Weak Airflow

Air from the vents feels weaker than expected.

Unusual Noises

Rattling, banging, or other unfamiliar sounds.

You may also notice a system that cycles on and off too often, uneven heat from room to room, a pilot or ignition that won’t stay lit, a thermostat that doesn’t seem to control the equipment, or a heating bill that jumps without a change in how you use your home.

Gas Furnaces, Heat Pumps and Electric Heat

Different systems fail in different ways. A gas furnace relies on ignition, burners, a flue and a heat exchanger, so safety checks are a core part of any visit. A heat pump moves heat using refrigerant and has a defrost cycle and emergency heat function that need to work properly. Electric heat depends on heating elements, sequencers and electrical connections. We diagnose the type of system you actually have rather than applying a one-size-fits-all fix.

Frequently Asked Questions

What kinds of heaters do you repair?

We diagnose and repair residential heating systems, including gas furnaces, heat pumps and electric heat, depending on the equipment and the problem.

Why is my heater blowing cold air?

Possible causes include a thermostat setting or problem, a dirty filter or restricted airflow, an ignition or control issue on a gas furnace, or a heat pump that is in a defrost or fault condition. A technician can test the system to find out which it is.

My furnace is making strange noises. Is that serious?

Banging, squealing, rattling or grinding can point to anything from a loose panel to a worn blower motor or ignition problems. It is best to have it inspected rather than keep running it and hope.

What should I do if I smell gas or suspect carbon monoxide?

Leave the affected area immediately and contact emergency services or your gas utility from a safe location. Do not wait for an online service request.

Do I need heater maintenance before winter?

Seasonal maintenance can help identify worn parts before the first cold snap, when heating systems are asked to work again after months of rest. See our maintenance plans for details.

Do you repair heaters in Buda and nearby communities?

Yes. We serve Kyle and across Hays County, Texas.
