How do Rockwall homeowners choose between HVAC and electrical options?
Heat Pump vs. Gas Furnace in Rockwall, TX
In Rockwall, a heat pump is the better choice for most homes without existing natural gas service, because our winters rarely stay below 35°F long enough for a heat pump to lose its efficiency advantage. If you already have gas at the meter and a working flue, a 80% AFUE furnace paired with a straight AC is usually cheaper to install and cheaper to run on the coldest 15 nights of the year.

A ductless mini-split is better when you're conditioning a space that has no ductwork — a garage, shop, sunroom, converted attic, or an addition. Central AC is better when a home already has ducts in reasonable condition, because a single central system costs less per conditioned square foot and keeps every room on one thermostat.

Upgrade to 200 amps if you are adding a Level 2 EV charger, a heat pump, an electric range, a hot tub, or a shop subpanel — or if your 100-amp panel is already full and relying on tandem breakers. A 100-amp service is still legal and safe for a small all-gas home with no large electric loads, but almost any modern electrification project pushes past it.
Read the comparisonRepair vs. Replace Your AC
Multiply the repair quote by the age of the system. If the result is over $5,000, replace it. A 14-year-old condenser needing a $400 capacitor is worth fixing; the same unit needing a $1,200 compressor is not. Systems still using R-22 refrigerant are almost always replacement candidates because the refrigerant alone can cost more than the repair.

A natural-gas standby generator is the better choice for multi-day Texas grid events, because it runs indefinitely on utility gas and can carry the whole house including central AC. A battery is better for short, frequent outages and for pairing with solar, but a single battery typically carries only critical circuits for 8–12 hours.
