Common HVAC Problems We Address in Hazelwood

Hazelwood’s location near Lambert Airport and the busy I-270 corridor means homes experience unique comfort challenges throughout the year. Summers are hot and humid, winters bring bitter cold, and older neighborhoods often face added strain on their systems. Stay Cool Climate Control provides HVAC services in Hazelwood, MO that solve the problems local families deal with most.

  • High Summer Humidity: The heavy St. Louis County air makes cooling less effective and harder on AC units. We provide dehumidifiers and AC tune-ups to keep homes cool and efficient.
  • Cold Winter Nights: Hazelwood furnaces often run nonstop in January and February, which can lead to breakdowns. Seasonal maintenance ensures systems stay dependable when temperatures drop.
  • Air Quality Concerns: Homes near major roads like Lindbergh Boulevard and I-270 deal with more dust and pollutants. Advanced filters and UV sanitizers help improve indoor air quality.
  • Older HVAC Systems: Many Hazelwood houses built in the mid-20th century still rely on outdated equipment. We offer replacements and upgrades that improve efficiency and comfort.
  • Uneven Heating and Cooling: Split-level and two-story homes often have hot and cold spots. Zoning systems and ductwork improvements bring balanced comfort to every room.

Hear from Our Satisfied Customers

Cole is very knowledgeable alot of information came my way. Almost a tad to much, but I am glad it came. As opposed to not enough information, in regards to what. He was seeing in our system, compared to other homes. He explained all my options on how to maintain our system. Or a complete new system with the issue with ours. No scare tactics,or trying to sell the biggest system. We ended up buying right in the middle range of systems, glad Cole explained all of our options. Update we purchased new HVAC system, along with a humidifier. Brandon and Carter were top notch, texted to let us know they were on their way. Originally told us about 8 hours to install, got it done in just over 6 I think. They didn't rush the install to get down quicker, they just are experienced. Professional from start to finish, Brandon explained every step he did. From the the new equipment how it flows,to new materials used to get it all completed. Carter was great showing me the thermostat and the Ac unit rundown outside. Great job boy's keep on doing.

I highly recommend Stay Cool Climate Control. They are a local and family-owned company. Cole came out and did a service check, he went over and explained what was wrong with my unit and went over some options. Eric came out and went over all my options. They both were very informative. Brandon did a great job installing my new system. He explained everything after the install was done. Being such a large purchase/investment, you want to go with someone you can trust. These guys are great!!

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.

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.
