AC Repair in Port Washington, WI

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

Port Washington's 1890s–1930s historic housing on Franklin Street and Van Buren Street bluffs, plus lakefront homes along the working marina and Wisconsin Avenue historic downtown present a wide range of AC challenges. Lake michigan's lake-effect climate and salt air accelerate condenser and coil corrosion, especially on blufftop homes that face prevailing northeast winds. Whether your system is blowing warm air, short-cycling, or refusing to start, our techs arrive stocked with parts for same-day repairs.

A historic lake michigan harbor city with a working marina, lighthouse, and distinctive bluff-top neighborhoods, 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 Port Washington's blufftop and lakefront neighborhoods. 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. Bluff-top homes from the 1890s–1930s on Franklin and Van Buren Streets often carry aging steam or gravity-furnace systems that require full HVAC redesigns.

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 Port Washington?

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