Martin-Jetco is a family owned and operated, full service heating and air conditioning company. We offer high quality commercial and residential service, and even work with St. Louis’ finest restoration companies to offer relief in the event of a flood, fire, or any other disaster. We have a strong focus on high quality and customer satisfaction — and we have the track record to prove it! We are a York “Premier Dealer”, and have been awarded “Dealer of the Year” an unprecedented 11 times running. In addition to our honors from York, we also carry an A+ rating with the Better Business Bureau, and have been awarded the Angie’s List “Super Service Award” 6 times. Customer feedback is very important to us, and has always been a primary influence on the way we do business. Our commitment even extends to customers who still use old-fashioned oil-fired furnaces. In fact, Martin-Jetco is St. Louis’ oldest and most sought after company for service on oil furnaces and boilers. We take pride in serving St Louis communities heating and cooling needs.  We are proud to offer a wide variety of high quality services to our customers, and pride ourselves on quality workmanship at an affordable price.

Regular maintenance is the single most important aspect in extending the life of your heating and cooling system. Some people believe that an occasional filter change is all that is required, and that they will call a service company when something breaks. This is not at all what is recommended. Heating and air conditioning systems contain hundreds of independent parts, all of which can fail without proper upkeep, and only trained technicians can access these parts. Ignoring your system’s needs not only puts you at a significantly higher risk of having a catastrophic breakdown during a hot summer or bitter cold winter, but also considerably reduce the life of your system. We have been servicing residential customers since 1964. We are located in Fenton, MO, but we offer service all over the greater St. Louis Area communities including St Louis, Kirkwood, Oakville, Kirkwood Missouri and parts of Illinois. We offer service, maintenance, and new installations on all brands, including York, Lennox, Trane, and Goodman. In addition to heating and cooling, we service and install water heaters, zoning systems, and make duct work modifications for room additions and new construction.

​Martin-Jetco not only services your current heating and air conditioning systems, but we also plan, fabricate, and install brand new, top of the line air conditioning systems. We will measure your home, either in person or using blueprints to ensure that we can choose the perfect HVAC system for your home. We work with you to be absolutely certain that you have enough “oomph” to keep your home comfortable, but also be sure that you are not paying too much for too large of a system or by wasting energy. ​We install high-efficiency air conditioning systems made by the best brands, like York, Lennox, Trane, and Goodman, just to name a few. We also use custom fabricated sheet metal duct-work made in-house by our professional installation department. We can also create and install zoning systems, and install convenient hardware like a WiFi communicating thermostat, which allows you to set your home to a comfortable temperature directly from your smartphone or wireless device. Aside from traditional heating and cooling systems, MJ also installs more modern, energy efficient alternatives like mini-split systems, which allow you to set each room to a different temperatures, or choose to turn off heating and cooling to specific rooms, all completely ductless.

Martin-Jetco’s work is approximately 60% residential and 40% commercial. We have worked on small commercial jobs like gas stations and restaurants, and big jobs, like strip malls, the Sullivan Firehouse, and the Lifetime Fitness Center in Ellisville (just to name a few!). We also work with landlords and their tenants to make sure that they get the most practical service or installation work for the best price.

We specialize in fire and water restoration. We are partnered with St. Louis’ best local contractors and restoration companies to assess the damage and repair or replace whatever is deemed necessary by the insurance companies and the owners. Martin-Jetco can provide emergency heating, cooling, or hot water access and then determine the best route to take to get the problem permanently resolved as painlessly and effortlessly as possible for everyone involved. Keep Martin-Jetco in mind should you suffer damage from a flood, fire, storm, or any other disaster!
