HVAC Services Duluth MN | Call Letourneau Heating & Refrigeration

Our local HVAC maintenance includes a thorough inspection and cleaning of your condensate drain line and pan. This is especially important in Duluth's humid climate, where algae and mold can quickly cause clogs. By scheduling regular tune-ups with us, we proactively clear this system to prevent water damage and system shutdowns.

While some frost is normal during a defrost cycle, a thick ice coating indicates a problem. Turn the system to 'off' (not just the thermostat) and call us. Letourneau's technicians are experienced with the freeze-thaw cycles here and will diagnose issues like low refrigerant or failing defrost components to prevent costly compressor damage.

For new installations, we recommend systems with robust defrost cycles and high-efficiency components that reduce runtime strain. We also install secondary condensate drain pans and safety switches as a standard precaution against overflow. Letourneau will ensure your new system is properly sized and configured for our cold winters and humid summers.
