Heating in Older Lewisville Homes

Lewisville is a mix. Homes around Old Town and the older subdivisions date to the 1970s and 1980s, while Castle Hills and newer sections went up in the late 1990s and 2000s. Either way, a big share of the city is at or past the age where systems wear out.

Most older Lewisville homes heat with a gas furnace in the attic or a hall closet, usually paired with a split AC. Oncor delivers power across Lewisville, and Atmos Energy supplies natural gas. We work throughout Lewisville, including Old Town Lewisville, Castle Hills, and the Lake Lewisville area.

Furnace Problems We Fix Every Winter

• No heat at all: failed ignitor, bad flame sensor, pressure switch, control board, or a tripped safety.
• Blowing cold air: flame sensor, high-limit trips from a clogged filter, or a heat pump stuck in defrost.
• Short cycling: the furnace lights, runs a minute, and shuts off.
• Noises and smells: squealing blowers, booming ignition, or a burning smell past the first run of the season.
• Heat pump iced over: defrost board, sensor, or low refrigerant.

Repair or Replace?

We give you both numbers in writing. As a rule, a furnace under 15 years old with a normal part failure is worth repairing. A furnace that is 20 or more years old with a cracked heat exchanger, or an R-22 heat pump with a refrigerant leak, is usually worth replacing. When it makes sense, we size the new system with an independent Manual J so you are not paying for more furnace than the house needs.

Questions We Get in Lewisville

Is it worth repairing an old furnace in Lewisville?
Often, yes. Ignitors, flame sensors, pressure switches, and blower motors are normal repairs on a furnace of any age. A cracked heat exchanger on an older furnace is different: that is a safety problem and usually means replacement.

Why is my furnace blowing cold air?
Common causes are a dirty flame sensor, a failed ignitor, a tripped high-limit switch from a clogged filter, or a heat pump stuck in defrost. We find the cause, show you, and price it before any work.

Do you check for carbon monoxide?
Yes. Every gas furnace call includes a combustion and carbon monoxide safety check. If you smell gas, leave the house and call 911 and Atmos Energy from outside first.

Do you fix heat pumps too?
Yes. We repair heat pumps, defrost controls, reversing valves, and auxiliary heat strips, and we service gas furnaces and electric furnaces.

Do you serve all of Lewisville?
Yes. We work across Lewisville (75057, 75067, and 75077), including Old Town Lewisville, Castle Hills, and the Lake Lewisville area.
