AC Repair and Replacement
The Midwest experiences hot summers that match the intensity of the cold winters. Don’t let a declining air conditioner make your home or office feel like a desert. The experts at Baer Heating & Cooling can repair many makes and models of residential and commercial air conditioners. AC units do not always break down during standard business hours, so we offer 24-hour emergency service for those early-morning or late-night HVAC crises. Our goal is to quickly fix your system the first time you call, but if your AC is beyond repair, we offer free estimates on new installations. Count on Baer to keep you cool this summer.
Maintenance Clean and Checks
The clunking of a furnace followed by an abrupt halt of heat blowing through your vents can be a scary experience. Rising temperatures and a broken thermostat can be equally frustrating. One of our goals at Baer Heating & Cooling is to avoid either of these scenarios from occurring. Many of the repairs that bring our technicians to homes and businesses could have been avoided through routine maintenance. By scheduling an annual appointment with one of our specialists, we can catch small glitches to avoid larger and more expensive repairs later. Prolong the life of your HVAC and avoid catastrophe with Baer’s tune-up service:
- A visual inspection of your entire system
- Cleaning the condensate drain
- Removing any debris
- Checking the electrical connections
- Inspecting the thermostat settings
- Assessing your exhaust outlets
- Monitoring the refrigerant levels


Improve Your Air Quality
You might be surprised to learn that many different contaminants are lurking in your indoor air. Because we cannot see them, we feel a false sense of security that the air is clean. Air ducts can trap and circulate mold, bacteria, dust, allergens, and other toxins. These pollutants are not good for anyone, but they may worsen symptoms for people with breathing issues like COPD or asthma. Make the call to Baer Heating & Cooling for air-purifying solutions. Let us install the following products to reduce allergens and contaminants for healthier air quality:
- Humidifiers
- Dehumidifiers
- High-efficiency HVAC filters
- In-duct air purifiers
- Ventilation control systems
- Carbon dioxide sensor
