Blesener Heating & Air Conditioning - Duluth's Certified HVAC Services

If you suspect carbon monoxide, leave your home immediately and call 911. For inspection and repair, our Duluth-based technicians are trained to identify and resolve the sources of carbon monoxide leaks, such as cracked heat exchangers or improper venting, which are critical safety checks, especially during our harsh winters when furnaces run constantly.

We recommend scheduling maintenance twice a year—ideally in the spring for your cooling system and in the fall for your heating system. This routine service helps prevent common local issues like dirty condenser coils from summer pollen and debris, ensures efficient operation during extreme temperatures, and can extend the lifespan of your equipment.

Signs include frequent repairs, uneven heating or cooling, a significant increase in energy bills, and the system being over 15 years old. Given Duluth's climate, an aging system struggles to maintain efficiency. We provide a straightforward assessment to help you decide if a replacement is a more cost-effective and reliable long-term solution for your home.
