AC Repair in Big Bend, WI

When your air conditioner breaks down during a Big Bend summer, you need a technician who can diagnose the problem and get your home cool again — today. Burkhardt Heating, Cooling, Plumbing & Electric has served Big Bend homeowners for more than 60 years, and our NATE-certified technicians are available 24/7 for emergency AC repairs.

Big Bend's older homes in the compact Fox River village core and rural properties on larger parcels in Vernon Township, many with private well water and propane heat present a wide range of AC challenges. Fox river flood plain considerations affect basement mechanical systems, and waukesha county's hard groundwater accelerates scale in water heaters and humidifiers. Whether your system is blowing warm air, short-cycling, or refusing to start, our techs arrive stocked with parts for same-day repairs.

A quiet waukesha county village on a bend in the fox river, within fox river park and vernon township, Burkhardt has built its reputation one repair at a time. We work on all major brands — Lennox, Carrier, Trane, Rheem, and Mitsubishi — and carry parts for current models and older units throughout Big Bend's Fox River village and rural Waukesha County properties. Upfront pricing before we start, always.

Common repairs: refrigerant leaks and recharges, failed capacitors or contactors, frozen evaporator coils, condenser fan motor failures, thermostat faults, and restricted airflow from dirty coils. Rural properties on larger parcels throughout Vernon Township often rely on propane and private well systems — equipment our technicians service throughout Waukesha County.

For systems over 12–15 years old, we provide an honest repair-vs.-replacement comparison. GreenSky financing is available for larger repairs or full replacements. Call 414-206-3049 anytime.

Thermostat and Controls

If your AC isn't cooling properly, the issue may be your thermostat rather than the unit itself. We diagnose and repair all thermostat types — programmable, smart (Nest, Ecobee, Honeywell), and standard models. Incorrect thermostat settings, dead batteries, faulty wiring, or a thermostat placed in direct sunlight can all cause cooling problems. We'll pinpoint the issue and get your system running right.

How quickly can Burkhardt respond to an AC repair call in Big Bend?

We offer 24/7 emergency service and aim for same-day response throughout Big Bend. For non-emergency calls, we typically schedule within 24–48 hours. Our trucks leave from Brown Deer each morning, keeping drive times to Big Bend short.

What are the most common reasons an AC stops cooling properly?

The most frequent causes are low refrigerant due to a leak, a failed capacitor or contactor in the outdoor unit, a dirty evaporator coil restricting airflow, or a faulty thermostat. Our NATE-certified technicians diagnose all of these on the first visit and carry the most common parts for same-day repair.
