A broken furnace can leave your home cold fast. Our furnace repair services in St. Louis help diagnose the issue, explain your options clearly, and get your system back up and running quickly. Whether you need a minor repair or a full furnace replacement, we help you choose the right solution for your budget and complete the work with care and professionalism.
Our heating system installation in St. Louis, MO covers everything from picking the right unit to running connections, sealing tight, and testing before we leave. A correct install means even warmth, better efficiency, and lower bills from day one.
Regular winter furnace maintenance helps prevent mid-season breakdowns. We clean burners, check heat exchangers, and test safety controls so small issues get caught early. A well-tuned system runs more efficiently and lasts longer.
Plumbing Masters handles three core heating services: furnace repair and replacement, new heating system installation, and seasonal maintenance and tune-ups. Whether your heat stopped working, your system is near the end of its life, or you want to keep a healthy furnace running well, our licensed technicians can diagnose the issue, explain your options in plain terms, and complete the work.
If your system is running but something feels off, like uneven rooms, strange noises or short cycling, a repair visit is usually the right start. If it is aging and needing frequent fixes, replacement may make more sense. If it works fine and you just want it ready for winter, book a tune-up. Not sure? Plumbing Masters will inspect it and recommend the right next step.
Watch for rooms that never warm up, a furnace that turns on and off constantly, rising energy bills without a clear reason, unusual banging or squealing noises, a burning smell that lingers, or a yellow burner flame instead of blue. Any of these can point to worn parts, airflow problems or ignition trouble. Catching them early usually means a simpler fix and fewer cold surprises.
Uneven heating usually comes from airflow problems, such as a clogged filter, closed or blocked vents, or leaky ductwork. It can also point to a thermostat in a poor location, rooms with less insulation, or a system that is not sized correctly for the house. Our technicians track down the cause and recommend the fix, whether that is a simple adjustment, a repair or a better fitting system.
Many furnaces last around 15 to 20 years, depending on how well they are maintained, how hard they work each winter and the quality of the original installation. Once a system reaches that range, repairs tend to become more frequent and efficiency drops. Yearly tune-ups help you get the most life from your equipment, and when replacement time comes, we help you plan it before a breakdown forces the decision.

Had an issue with my new dryer. I smelled gas when opening the dryer door. Rick came out and determined there was a faulty gas line. He replaced it with a new flexible line. Everything is working fine now.Posted on Google![]()

Needed to have the kitchen drain line cleared for the first time after 30 years in the house. Was able to schedule service promptly, which was handled professionally and competently. I think the price for the drain cleaning was reasonable, though it is a bit higher than what is seen sometimes in online advertising from other companies. Have been using plumbing master’s for many years and things are always handled competently by respectful and knowledgeable professionals.Posted on Google![]()

Yesterday I reached out to get on schedule to replace my outdoor spigot. Lucy was able to fit me in today for repair. Lorenzo was amazing! He got me fixed up in no time & walked me through steps to prevent line from busting/freezing next season! Shout out to Jared & Brian from previous repairs! Every experience I’ve had with Plumbing Masters has been great! Highly recommend!
