Common HVAC Issues We Fix in Lake St. Louis

Homes in Lake St. Louis face unique challenges thanks to Missouri’s shifting seasons and the area’s lakeside climate. From older properties near the water to newer builds in family neighborhoods, HVAC systems here work hard year-round and often show signs of wear. High summer humidity around the lake forces AC units to run longer and harder, making dehumidifiers and tune-ups essential for comfort and efficiency. Cold winter temperatures push furnaces to their limits, creating a greater need for seasonal maintenance to prevent breakdowns. Multi-level homes frequently deal with uneven heating and cooling, which zoning systems and ductwork improvements can resolve. Pollen and dust from the surrounding area also affect indoor air quality, but advanced filters and UV sanitizers keep the air cleaner and healthier.

I had Stay Cool come out for my furnace that quit working while I had just had surgery. Cindy was able to get someone out right away, I had signed up for the membership club that saved me on my repairs, and felt very confident in the technician. He made me feel at ease and comfortable in my decision . Very friendly company that does the job right the first time!

Nathan and Trey came out to do an installation on the exterior, but stuck around to help test my system and give guidance on improving house heating. We found an issue with a fan not being connected to an exhaust pipe and they went out, got materials, and came back and fixed it that day!
