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, Missouri and parts of Illinois. We offer service, maintenance, and new installations on all brands, including York, Lennox, Trane, and Bryant. 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 Bryant, 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 temperature, 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.

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.
