Recent Project: Furnace Swap in Scottsdale
Wrapped up a full furnace replacement in Scottsdale last week for a homeowner whose 22-year-old system finally called it quits. The old unit was oversized for the home, short-cycled constantly, and had a cracked heat exchanger our tech spotted during the diagnostic. We sized the new furnace properly using a Manual J calculation, upgraded the flue venting to current code, replaced a section of return duct that was leaking into the attic, and set up a smart thermostat the homeowner can control from her phone. Total install time was one day. The homeowner already reported quieter operation and more even heat between rooms. This is what a proper install looks like. If your system is more than 15 years old, let Rush HVAC Services take a look before winter.
