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.

Hear from Our Satisfied Customers

I highly recommend Stay Cool Climate Control. Everyone from the office to the technician is extremely professional, courteous and a pleasure to work with. Our technician today was Cole. He notified us when he was on his way. While here, he patiently walked us through the current state of our HVAC and recommended having the blower motor cleaned. There was no high pressure sales pitch, just facts.

Cole W was out not only to do bi/yearly check and maintenance, but we also had issues with the heat coming on. He was very professional and the nicest person I have encountered in a while. Every time we have had this company out including installation they have been so nice. I would give them a 10 out of 10 each visit!

Jacob was very professional and courteous. Let us know the return air to the blower was undersized. Recommended we replace the blower in the future if necessary rather than replace expensive ductwork now.
