Keller sits in IECC Climate Zone 3A, and your HVAC system works hard here in two directions. Cooling season runs from late May through early October, with stretches above 100 for weeks and brutal sun pulling the latent heat right out of the building envelope. Winters bring 25-degree mornings, the occasional ice storm pushing down from the panhandle, and the rare February deep freeze that wipes out unprepared heat pumps. Hailstorms across north Tarrant County beat up outdoor coils most years, so your equipment sees wear most months out of the year.
Most Keller homes run gas furnaces paired with central air conditioners. That has been the standard setup across Tarrant County for decades, and it handles the temperature range well. Heat pumps are turning up more often in newer construction, especially in Marshall Ridge townhomes and the recent Estancia builds. Ductless mini-splits are popular in home additions, finished garages, and bonus rooms above garages across Hidden Lakes, Old Town Keller, and the older sections off Florence Road.
We work on all of it. Gas furnaces, heat pumps, central air conditioners, and ductless mini-splits. If it heats or cools your Keller home, we can fix it. Call (817) 945-6320 and tell us what is happening. We get a tech to your home for AC repair or heating repair the same day.
Gas furnaces in Keller run more often than most homeowners realize because of the cold north Texas mornings from December through February. A failed igniter, a cracked heat exchanger, or a dirty flame sensor are the top causes of no heat. When a January cold front drops the lows into the 20s for a week, a furnace that will not fire makes the house feel miserable. We carry igniters, flame sensors, and control boards on every truck. Most furnace repairs across Keller run $150 to $500 and we wrap them up the same day you call.
Heat pumps work well in Keller most of the year, but they take a beating during the rare deep-freeze events like the February 2021 storm. Hail dents the reversing valve cover and outdoor coil. A failed defrost board or a stuck reversing valve blocks the system from switching between heating and cooling modes. Low refrigerant hits both modes. If your heat pump is blowing lukewarm air either way, call us before the compressor takes damage.
One room is freezing, the next is sweltering. In most Keller homes that comes back to ductwork. Flex duct in unconditioned attics, common in older homes around Old Town Keller, along Bates Street, and in the older tracts of Bear Creek, breaks down over 8 to 12 years in attic temps that hit 140 in summer. Connections come loose, insulation flattens, and dampers seize. We look at the ductwork, find the splits or restrictions, and fix them so every room gets the airflow it was designed for.
Before you toss the thermostat, check the batteries. We get this call all the time. Beyond batteries, thermostat problems include loose wiring from temperature swings, gaps between newer smart thermostats and older HVAC gear, and bad settings that block startup. If the screen is lit but nothing happens when you change the temp, call us at (817) 945-6320. Usually a quick fix.
