Furnace replaced, house still uneven
A new furnace on original ductwork can still leave the lower level cold and the bedrooms warm. Damper adjustments, a better return path and a properly set blower speed often fix it without new ducts.

View details ↗03AC Repair
Central air on the furnace’s ductwork: weak capacitors, low refrigerant from slow leaks and frozen indoor coils on the first hot weekend.
View details ↗04Heat Pumps

What tends to come up in Peterson Park’s mid-century homes.
Ask a pro↗
AC that ices up in July
A frozen line or coil usually means low airflow or low refrigerant. Turn the AC off, let it thaw, check the filter, and call if it freezes again.
Short cycling in mild weather
An oversized replacement furnace heats the house in a few minutes and shuts off, over and over. A two-stage or modulating furnace, or correct sizing, evens that out.
Before you replace anything
Sizing a New Furnace and AC in Peterson Park
The old furnace’s size is not a good guide. Many original units were oversized, and insulation and windows have changed since. A load calculation based on the house gives a better answer and avoids short cycling.
If the AC is close in age to the furnace, ask for both options in the estimate. A matched furnace and coil is easier to get right in one visit than a second project a year later.

Most furnaces last around 15 to 20 years with yearly service. A furnace past that range that needs a major part, like a heat exchanger or blower motor, is often a candidate for replacement.
As a dual-fuel setup, often yes: the heat pump cools in summer and heats in mild weather, and the gas furnace takes over on the coldest days. It’s a practical choice when the AC needs replacing.
Cleaning the burners and flame sensor, checking the igniter, testing safety switches, measuring gas pressure and temperature rise, and checking the venting and for carbon monoxide. It usually takes about an hour.
