Why Lewisville Homeowners Choose Frosty's for Heating Repair
Lewisville's mix of established neighborhoods and new construction means we see every type of heating system — from 20-year-old gas furnaces in Highlands to modern heat pumps in Castle Hills. Frosty's HVAC has been providing heating repair throughout Lewisville since 2018, and our technicians carry parts for all common heating repairs, enabling same-visit fixes for most issues.
The humidity near Lewisville Lake can affect heating system components too. Moisture accelerates corrosion on electrical connections and can cause premature failure of ignitors and flame sensors. During heating season, we see more flame sensor failures in Lewisville than in drier areas — the sensor corrodes faster and can't detect the pilot flame properly, causing the furnace to shut down as a safety precaution. A flame sensor replacement is $400 ($340 for members) and takes about 30 minutes.
When temperatures drop during Texas cold fronts, demand for heating repair spikes. Frosty Club members in Lewisville get priority scheduling — while non-members may wait 1-2 days during peak demand, our members get same-day service. That's the peace of mind that makes the $99/year Basic membership worth every penny.
