Common repairsWhy is my AC running but not cooling the houseA running AC that doesn't cool usually means a refrigerant leak, blocked condenser, or dirty evaporator coil, all requiring professional diagnosis.
EmergenciesHow do I know if my furnace heat exchanger is crackedA cracked heat exchanger cannot be safely repaired and means you need a new furnace because carbon monoxide can enter your home.
CostsWhat should I budget for an HVAC system replacement in 2026A complete HVAC replacement typically costs between five thousand and twelve thousand dollars depending on system size, efficiency level, and your location.
Common repairsCan I replace just my AC condenser without replacing the indoor coilReplacing only the outdoor condenser without the indoor coil is possible but risky because mismatched equipment causes poor efficiency and can shorten both component lifespans.
Common repairsWhy does my thermostat show one temperature but feel different in different roomsUneven room temperatures mean your thermostat sensor is in a poor location, your ductwork is blocked, or your system lacks zoning and cannot balance air to different areas.
MaintenanceHow often should I replace my furnace or AC air filterReplace your HVAC filter every one to three months depending on filter thickness, whether you have pets, and how dusty your home environment is.
