Why LewisvilleHomeowners Choose Frosty's
Lewisville sits at the crossroads of I-35E and 121, making it one of the most connected cities in the area — and Frosty's HVAC takes advantage of that proximity to deliver fast, reliable service throughout Castle Hills, Highlands, Orchard Hill, and Valley Oaks. Lewisville's housing mix is incredibly diverse: luxury homes in Castle Hills, established families in Highlands, starter homes in Valley Oaks, and everything in between. Each neighborhood has different HVAC needs based on home size, age, and construction quality.
Lewisville homeowners choose Frosty's because we understand that HVAC service isn't one-size-fits-all. A 1,200 sq ft starter home in Valley Oaks has completely different cooling requirements than a 4,000 sq ft home in Castle Hills. We size our recommendations to your actual home — not to our bottom line. Omar Jacobo has personally serviced hundreds of Lewisville homes since 2018 and knows which neighborhoods have common ductwork issues, which developments used specific equipment brands, and which areas are prone to electrical problems. That local knowledge saves you time and money on every service call.
Common HVAC Problems in Lewisville
Refrigerant Leaks in Heat-Stressed Systems
Lewisville's position in the Texas heat island means outdoor temperatures regularly exceed 100°F for weeks at a time in summer. This thermal stress causes refrigerant line connections to expand and contract, leading to slow leaks that gradually reduce cooling capacity. Homeowners notice their AC running longer and longer without reaching the set temperature. We locate leaks using electronic detection, repair the connection, and recharge the system to manufacturer specifications.
Inconsistent Heating in Slab-on-Grade Homes
Many Lewisville homes, especially in Highlands and Orchard Hill, are built on concrete slabs without basements. During cold snaps, the slab radiates cold upward, making ground-floor rooms uncomfortable even when the furnace is running. We address this with proper return air balancing, thermostat relocation from exterior walls, and in some cases, supplemental heating solutions for the most affected rooms.
Capacitor and Contactor Failures
The electrical components in outdoor condenser units — particularly capacitors and contactors — take a beating in Texas heat and fail more frequently than in milder climates. A failed capacitor causes the compressor or fan motor to stop working, usually on the hottest day of the year. We carry all common capacitor sizes and contactors in our vans for same-day replacement, typically completing the repair in under an hour.
