Welsch Provides a Variety of Heating Services

Homes all over Maryland Heights rely on a variety of different heating systems to keep warm. Just because you don’t have a furnace, doesn’t mean you can’t find a quality technician to provide service to your heating system. Welsch can help with a variety of services, such as:

Furnace Installation

Furnaces tend to last 15-20 years. If your furnace is approaching this age and you’ve experienced frequent issues, its a good idea to start thinking about replacing it. Talk to Welsch to learn more about new furnace models and how they can heat your home more efficiently.

Furnace Maintenance

Call Welsch before the heating season begins to schedule your annual furnace maintenance service. Furnace maintenance can save you lots of money on repair costs and energy bills.

Furnace Repairs

It’s not uncommon for your furnace to need repairs, and not every repair signals the end of your furnace’s life. Oftentimes, a quick repair can be inexpensive and can restore your home to a comfortable state. If you ignore furnace issues, the more likely they are to cause worse issues within your furnace, which could result in a heftier repair bill.

Heat Pump Installation

Many homes in Maryland Heights use heat pumps for year-round comfort. These systems are incredibly energy efficient and don’t use natural gas to heat your home. When paired with ductless mini splits, your home can be divided into zones, allowing your family members to have more control over the temperatures in their area without raising your heating bills.

Heat Pump Maintenance

Since heat pumps work throughout the year, they need to be maintained twice a year. Schedule your maintenance for the summer season by calling for cooling maintenance in the spring, and then again in the fall before you turn on your heat for the first time.

Heat Pump Repairs

Needing the occasional heat pump repair is not abnormal. Heat pumps are often under a lot of stress because they work so hard to make your home comfortable. When you notice issues with your heat pump, schedule service with Welsch right away.

Call Welsch to Improve Your Home’s Indoor Air Quality

Improving your home’s indoor air quality makes your air healthier and your home much more comfortable. Thermostats are the brains of your HVAC system. If your home seems stuffy, has uneven temperatures, or it doesn’t feel like the setting on the thermostat, your thermostat could be experiencing issues. We can help with repair or replacement thermostat services to keep your home consistently comfortable.

In the winter, you might notice your family members sneezing and coughing more. You might also be annoyed by static electricity shocking you with every surface you touch. These issues are caused by dry air. A humidifier can add moisture to the air in your entire home which can elevate these issues. Portable humidifiers need to be changed and refilled frequently. A whole house humidifier needs very little maintenance and is plumbed directly to your water line so you don’t have to worry about refilling a tank.

Every HVAC system has an air filter that removes particulate matter from the air. This only does so much to help with your indoor air quality. By upgrading your HVAC system with an air cleaner, you’ll have more powerful filters working around the clock to keep the air you breathe clean and free of bacteria, allergens, and pathogens that make your family sick.

Welsch did a great job installing our outdoor a/c unit and replacing the coil. Quick, professional, polite and treated my fiancé with respect. Really appreciate the work they did.

Thanks so much for taking care of our urgent heating needs.

I had other bids for an A/C and furnace, and Welsh was not the lowest bid, but it was the professionalism and knowledge of Rick (estimator), and the Lennox product that caused me to choose Welsh (for the 2nd time) to install the new system. I was just as impressed...


Our family tried 4 other company’s in St. Louis to replace old boiler and three AC units for a 4,500 sq. ft. , 100 year old home. It was a VERY complex project involving a lot of thought and creativity. The project was also completed a week before its expected...


Enclosed is payment for my new A/C and furnace. Your workmen were exceptional. Ilene O.
