Professional HVAC Solutions for Creve Coeur Homes and Businesses

When temperatures soar above 90 degrees in July or plummet below freezing in January, Creve Coeur residents depend on their heating and cooling systems to maintain comfortable indoor environments. At Reliable Heating and Cooling, we understand the unique climate challenges that properties in this area face throughout the year. The humid continental climate of Missouri creates demanding conditions that require robust, properly maintained HVAC systems capable of handling extreme temperature swings and high humidity levels during summer months.

Since Ken and Marilyn Patterson founded our company in 1972, we’ve developed deep expertise in addressing the specific heating and cooling needs of Creve Coeur properties. The residential neighborhoods throughout the area, from the established homes near Bellerive Country Club to newer developments along Olive Boulevard, each present distinct HVAC requirements based on construction styles, insulation levels, and architectural designs. We approach every installation and service call with a commitment to creating a comfortable and healthy living space by providing the highest degree of quality installation and service work in the residential and light commercial marketplace with honesty and integrity.

Comprehensive Heating Services for Missouri Winters

Heating systems in Creve Coeur work overtime during the winter months when temperatures regularly drop into the twenties and occasional Arctic blasts push mercury even lower. Modern furnaces operate through sophisticated heat exchange processes, where natural gas or propane combusts in a sealed chamber while air circulates around the exterior of the heat exchanger, absorbing thermal energy before distribution throughout your property. Electric heat pumps, increasingly popular in our service area, utilize refrigerant compression cycles to extract heat from outdoor air even in cold conditions, offering remarkable efficiency ratings that can reduce heating costs by 30 to 40 percent compared to traditional electric resistance heating.

Our heating services encompass complete system installations, where we calculate precise load requirements using Manual J methodology that factors in square footage, insulation R-values, window efficiency ratings, and air infiltration rates. Regular maintenance involves cleaning burner assemblies, inspecting heat exchangers for microscopic cracks that could lead to carbon monoxide leaks, testing safety controls including flame sensors and limit switches, and verifying proper combustion air supply and exhaust venting. When our company incorporated on March 20, 1980, we made a commitment to staying current with evolving heating technologies, which now includes variable-speed blower motors that adjust airflow incrementally for enhanced comfort and reduced energy consumption.

Advanced Cooling Systems for Hot, Humid Summers

Air conditioning systems face intense demands in Creve Coeur when summer humidity levels routinely exceed 70 percent while temperatures climb into the nineties. The refrigeration cycle that powers modern cooling systems involves precise pressure and temperature relationships as refrigerant transitions between liquid and gas states, absorbing heat from indoor air at the evaporator coil and releasing it outdoors through the condenser unit. Proper sizing proves critical because oversized systems cycle too frequently, failing to run long enough to extract moisture from the air, while undersized units struggle to maintain comfortable temperatures during peak heat periods.

We install high-efficiency systems featuring SEER ratings of 16 and above, incorporating advanced components like two-stage compressors that operate at reduced capacity during mild conditions for improved dehumidification and energy savings. Microchannel condenser coils increase heat transfer efficiency while reducing refrigerant charge requirements by up to 40 percent. Variable refrigerant flow systems provide zoned comfort control, allowing different areas to maintain independent temperature settings while maximizing overall system efficiency.

Essential HVAC Maintenance and Indoor Air Quality Solutions

Regular HVAC maintenance extends equipment lifespan while maintaining peak operating efficiency and preventing unexpected breakdowns during extreme weather events. Our comprehensive maintenance protocols include:

  • Filter inspection and replacement to maintain proper airflow and protect internal components from dust accumulation
  • Refrigerant charge verification using superheat and subcooling calculations to ensure optimal cooling performance
  • Electrical connection testing to identify loose terminals that cause component failure and energy waste
  • Condensate drainage system cleaning to prevent water damage and biological growth
  • Thermostat calibration to ensure accurate temperature control and programming functionality

Indoor air quality concerns have gained prominence as homes become increasingly airtight for energy efficiency. We install and service whole-house air purification systems utilizing MERV-rated filtration, ultraviolet germicidal irradiation, and bipolar ionization technologies to neutralize airborne pathogens, allergens, and volatile organic compounds. Humidity control through whole-house humidifiers and dehumidifiers maintains optimal 40 to 50 percent relative humidity levels year-round, preventing dry air discomfort in winter and moisture-related issues during summer.

At Reliable Heating and Cooling, we remain committed to serving the Creve Coeur community with professional HVAC solutions that prioritize comfort, efficiency, and reliability for every customer we serve.

Customer Reviews
What our customers are saying

We had a emergency water leak problem with our AC unit in the basement of our recently purchased condo. Called Reliable and Derrick was there within a couple of hours. He was polite, knowledgeable, and friendly. Derrick quickly found the problem and repaired it. He also checked the system overall, pointed our some concerns and answered all my questions. I can’t say enough about how satisfied we were with Derrick and Reliable Heating & Cooling! We would definitely recommend them!!! Thanks again!!!!

Terry Mills

We have used Reliable Heating and cooling for all of our heating and cooling needs. We needed some water heater work and Ralph came out and took care of it right away. Ralph was very professional and knowledgeable. He got the job done very quickly and everything is working great! I always recommend Reliable to family and friends. They truly are Reliable!

Chris Lopez

Had a small gas leak for a property I was helping a friend sell and we found out late last night. We reached out to Reliable H&C and Derrick was over first thing in the morning. He was friendly, professional and knowledgeable. He answered my questions with a smile. Derrick was a rock star. Will absolutely call him again. Bravo

Connor Kapp

Have been with them for more than 10 years. They provide exceptional service…from the time they call to remind you about setting an appointment to the actual service day. Derek (and all their other technicians) are knowledgeable, professional, prompt, and open to listening to questions and pay attention to details. Never had a problem with anything. Thank you for a job well done. Good pricing.

Seema Chouhan

I had a system malfunction on Sunday evening December 12, 2022 on my Carrier Infinity ICS purchased in 2008.I am a first time caller to Reliable. Marty called me back and had his Tech dispatched at 8 AM the next day. The unit had failed and was dangerous to use. He had a new system by the next morning. They installed it and I was completely satisfied with their service and response time. I overwhelmingly recommend Reliable and will be using them from now on.

DM

Reliable has installed and maintained our last 2 furnaces and AC. Our experience with them has been great. Just yesterday we had an issue with our AC. I talked to Marty and he said he’d have someone out the next day. They even were able to accommodate us with an afternoon call. Derrick arrived promptly on time and had us up and going again in 15 minutes (bad capacitor on the condenser unit fan motor). With the prediction of high 90 temps, we were so thankful to have AC working again.
