Replacing Heat in an Older Tempe House

A lot of Tempe heating equipment sits in homes built in the 1950s and 1960s, when the city’s postwar subdivisions spread south and east of downtown. Furnace replacement in Tempe often involves more than swapping a box: older venting, small closets and original gas lines all need checking before new equipment goes in.

Options for Tempe Homes

  • Gas furnace replacement where gas is already in place, with the flue and venting brought up to current code.
  • Heat pump to replace both an old furnace and an old air conditioner with one system.
  • Packaged rooftop unit replacement for homes with all-in-one equipment on a flat roof.

Checks Before We Quote

  1. Venting: older flues may not suit a new furnace, and condensing furnaces need different venting.
  2. Gas line size and condition.
  3. Closet or attic space for safe access and clearances.
  4. The age of the air conditioner, since replacing both together is often cheaper.

Permits

Heating replacements are permitted through the City of Tempe Permit Center. We file the permit, test for carbon monoxide at startup and leave you with the equipment paperwork.

Install Day

For a like-for-like gas furnace, we shut off gas and power, remove the old unit and set the new one. Next we reconnect the gas line, flue and wiring, and fit a new filter rack if the old one is a poor fit. We run the furnace through full heating cycles and check gas pressure and temperature rise. Then we test for carbon monoxide around the furnace and in the living space. Rooftop packaged units need a crane or lift on some homes, and we schedule that in advance.

Common Questions

Is a heat pump a good fit for an older Tempe home?

Often, yes, especially if the AC is also due. We check the electrical service and ductwork first.

How long does a furnace replacement take?

Usually one day for a like-for-like swap. Venting or gas line work can add time.
