What an HVAC upgrade looks like
Drag the slider to compare. These are illustrative stock photos, not jobs completed by contractors in our network.
Worn-out AC → new high-efficiency condenser
Aging units that need constant repair are replaced with a correctly sized, higher-SEER2 system on a matched coil.
AC Replacement & Installation →
Crushed flex duct → sealed, rigid supply duct
Kinked, torn flex runs starve rooms of air. Replacing and sealing them restores airflow to hot bedrooms.
Duct Repair & Sealing →
Basic thermostat → smart thermostat
A smart thermostat, wired with a C-wire and set up for your equipment, adds scheduling and remote control.
Thermostat Installation & Repair →
Old wall unit → ductless mini-split
Noisy, inefficient wall units are replaced by a quiet mini-split head with its own thermostat.
Ductless Mini-Split Installation →
Corroded condenser → new heat pump

Climate matters
HVAC needs change with your climate
Hot-humid
Long cooling seasons and high humidity. Correct sizing, duct sealing and clean condensate drains matter as much as raw cooling power.
Alabama · Florida · Georgia · Louisiana
Hot-dry
Extreme dry heat, attic and rooftop equipment, and dust. Capacitors, coils and evaporative coolers need regular attention.
Arizona · Nevada · New Mexico
Mixed
Real heating and cooling seasons. Heat pumps and dual-fuel systems are popular, and both spring and fall maintenance pay off.
Arkansas · California · Delaware · Kansas
Cold
Heating dominates. Furnace and boiler reliability, combustion safety and clear vents are the priorities, with summer AC still needed.
Colorado · Connecticut · Idaho · Illinois
