Berndt Climate Control LLC provides a full range of HVAC services for homeowners and small businesses in Verona, Wisconsin and throughout Dane County. From emergency furnace repair on the coldest night of winter to new air conditioning installation before the summer heat arrives, our team has the training and experience to handle any heating or cooling need.
All work is performed by Sarah Berndt, EPA 608 certified and licensed as a Wisconsin HVAC contractor. We carry liability insurance and stand behind our work with a one-year labor warranty on all repairs and installations.
We install new central air conditioning systems for homes and light commercial buildings. Our process includes a thorough load calculation to ensure proper sizing, followed by professional installation of the air handler, condenser, refrigerant lines, and all electrical connections. We work with Carrier, Lennox, Trane, Rheem, Goodman, and York equipment.
Ductless mini-split systems are ideal for homes without existing ductwork, room additions, or areas requiring independent temperature control. We install single-zone and multi-zone systems with high-efficiency ratings up to 24 SEER.
We diagnose and repair all makes and models of residential and light commercial air conditioning equipment. Common repairs include refrigerant recharge, compressor replacement, capacitor and contactor replacement, coil cleaning, and thermostat repair.
Annual air conditioning maintenance keeps your system running at peak efficiency and helps prevent unexpected breakdowns during summer. Our spring tune-up includes 15-point inspection of all mechanical and electrical components, coil cleaning, and refrigerant check.
We install high-efficiency gas furnaces with AFUE ratings from 80% to 98%. Our installation process includes proper sizing, ductwork inspection, venting, gas line connections, and full system commissioning. We offer free estimates on all new furnace installations.
Our technicians diagnose and repair all furnace problems including igniter failure, heat exchanger cracks, blower motor issues, gas valve problems, and control board failures. We stock common parts to complete most repairs on the first visit.
Heat pumps provide efficient heating and cooling from a single system. We install and service air-source heat pumps and can advise on whether a heat pump is cost-effective for your Wisconsin home based on your heating load and utility rates.
We service hot water and steam boilers for residential and light commercial applications. Services include annual maintenance, circulator pump replacement, pressure relief valve testing, zone valve repair, and complete system diagnostics.
Prepare your heating system for a Wisconsin winter with our 15-point fall furnace inspection. We check heat exchangers, burners, ignition systems, safety controls, flue venting, and filter condition to ensure reliable performance all season.
Electronic air cleaners and media filtration systems remove dust, pollen, pet dander, mold spores, and other airborne contaminants from your home. These systems integrate with your existing HVAC equipment for whole-home coverage.
Wisconsin winters are extremely dry, which can cause discomfort, static electricity, and damage to wood floors and furniture. Whole-home humidifiers connected to your furnace maintain healthy humidity levels throughout the heating season.
UV light systems installed in your air handler kill bacteria, viruses, and mold that can grow on coils and circulate through your ductwork. These systems provide continuous protection without filters to replace.
Leaky or poorly designed ductwork can waste 20-30% of your conditioned air. We inspect, seal, and repair residential ductwork to improve efficiency and comfort. We also perform duct cleaning for systems with excessive dust or contamination.
Our maintenance agreement includes two visits per year — a spring AC tune-up and a fall furnace tune-up. Agreement holders receive priority scheduling, discounted service rates, and no overtime charges on emergency calls. Annual agreements help extend equipment life and maintain manufacturer warranties.
Scheduled before the cooling season, our AC tune-up includes cleaning condenser coils, checking refrigerant charge, lubricating moving parts, testing electrical components, and verifying thermostat calibration. A properly maintained AC uses significantly less energy.
Scheduled before the heating season, our furnace tune-up includes inspecting the heat exchanger, cleaning burners, testing safety controls, checking flue venting, replacing filters, and verifying thermostat operation. We provide a written report on system condition.
We provide around-the-clock emergency heating and cooling service. If your furnace fails during a Wisconsin winter or your air conditioning stops working on the hottest day of summer, call (608) 556-0324 and a technician will be dispatched promptly.
We serve offices, retail spaces, restaurants, and light industrial facilities with the same quality service we provide to homeowners. Commercial services include rooftop unit maintenance, split system service, and commercial refrigeration support.
