HVAC Installation in St. Louis
Serving St. Louis Since 1964, Without Unnecessary Upsells
As a family-owned, licensed heating and cooling company, we recommend equipment based on what your home or business actually needs. Our technicians hold North American Technician Excellence certification, commonly called NATE certification, and carefully evaluate each property before discussing options.
We’re certified dealers for York, Goodman, Daikin, Carrier, and Trane. That access lets us compare systems from five major brands instead of limiting you to a single product line. We focus on finding a suitable system and installing it correctly, not selling unnecessary products or services.

What Professional HVAC Installation Involves
The process begins with evaluating the property and determining the appropriate system size. Building layout, equipment placement, existing components, and required capacity all influence system selection. A unit that’s too large or too small can compromise comfort, efficiency, and long-term performance.
Our approach includes:
- Evaluating the home or commercial property before recommending equipment.
- Comparing suitable systems from our available manufacturers.
- Tailoring the installation to the building’s heating and cooling requirements.
- Checking the system for correct setup and operation.
We offer financing options, including a 0% financing plan, for eligible customers managing installation costs. Once the work is complete, our Home Comfort Agreement maintenance plan can protect the system through routine professional care.
When Repair Gives Way to HVAC Replacement
Replacement may be worth considering when equipment is more than 10 to 15 years old or requires increasingly frequent, costly repairs. The right choice depends on the system’s condition, repair history, current performance, and the expense of keeping it in service.
Newer energy-efficient HVAC systems generally provide better efficiency and more advanced controls than older equipment. Proper sizing is particularly important in St. Louis, where hot, humid summers and cold winters keep heating and cooling systems working throughout the year.
Heating & Cooling Systems We Install
We install new and replacement equipment for homes and commercial properties, including:
- Central Air Conditioners: Whole-building cooling connected to a compatible duct system.
- Furnaces: Central heating equipment sized for the property’s needs.
- Heat Pumps: Efficient systems that provide heating and cooling from one unit.
- Ductless Mini-Split Systems: Zoned comfort for buildings without conventional ductwork or spaces requiring targeted temperature control.
Before recommending any system, we assess the property, discuss your priorities, and identify options that fit the building rather than relying on a one-size-fits-all package.

We love Martin-Jetco! We had an issue with needing a new heat pump and AC only a year and a half after buying our house. and they walked through all our options and had a new system ready to install in matter of days! (In the middle of summer last year!) Then whenever we have user issues (In our case forgetting to change our filter promptly, which had minor repercussions!) they are always willing and able to help as soon as possible!
