HVAC Repair in Wisconsin — 24/7 Heating & Air Conditioning Service

Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in Wisconsin with pets, ongoing construction nearby, or a high-MERV filter in an undersized return should move to monthly changes. A loaded filter is the single most common cause of frozen coils and failed blower motors.

All of them. Our technicians are trained on Carrier, Trane, Lennox, Rheem and essentially every other residential brand sold in Wisconsin, including discontinued lines. We keep a broad parts catalogue on the trucks for exactly that reason.

Refrigerant does not get "used up" the way fuel does. If your charge is low, there is a leak somewhere — usually at a flare connection, a schrader core or the evaporator coil. We locate and repair the leak rather than simply topping up the charge, because a top-up alone will fail again.

Almost always a blocked condensate drain line, a failed drain pan float switch, or a frozen coil melting faster than the pan can handle. In Wisconsin we see algae and dust clogging drain lines constantly during June through August. It is a fast fix but ignoring it ends in ceiling damage.

We can give you realistic ranges — and this page lists the ones homeowners in Wisconsin see most often — but a firm price needs eyes on the equipment. Any company that quotes a final number without seeing the unit is usually quoting low to get through the door.
