Heating Services

St. Louis winters can be challenging and freezing cold. Without a heating system you can trust for the entire winter, you are at risk of being displaced or worse. If your heating system needs attention during the winter, call the pros at Welsch Heating & Cooling. With 125 years of serving the St. Louis community, we have the experience, tools, and professionals to keep your furnace running all winter long.

We also help with full remodels where you change from a boiler to a furnace or heat pump. 

Heating Repair Services

If your furnace or heating system is not performing as expected, give Welch Heating & Cooling a call. We provide exceptional heating repair services, no matter the system. Some of the common signs that your heating system is not functioning include: 

  • Poor heat distribution. Larger rooms are not warming like they used to. 
  • Cold spots throughout the home. The indoor ambient temperature is not equal. 
  • Short cycling. The furnace is turning on and off more often than it used to do. 
  • The system won’t turn on. There is no power to the system and, therefore, no heat. 

Welsch Heating & Cooling recommends that you call for service as soon as you begin to notice changes in how your heating system performs. Catching some issues early before they become permanent damage can save homeowners a lot of money. 

Heating Maintenance Services

Furnaces and heating systems should be maintained by a professional once per year. However, if your home has an older system, consider calling for maintenance twice per year. 

A heat pump needs servicing twice per year, once before winter hits and once before the heat of summer begins. 

Heating system maintenance keeps your heating system operating at its most efficient levels. Efficiency in a heating system is a measurement of how well the unit does its job compared to how much energy it uses. As units age, they require more energy to do the same amount of heating. 

When you call Welsch Heating & Cooling, we maintain your heating system so that it is:

  • Clean
  • The burner or heating element is free of debris or corrosion
  • Safe to use without fumes or gas buildup
  • Functioning at peak efficiency 
  • Free of loose or broken parts

A well-maintained heating system will see you through the worst of winter weather. Our heating and cooling technicians are highly trained and work quickly to maintain your heating system. Some common signs your heating system needs servicing include:

  • The heating system is slow to start
  • The unit is not heating the home or business thoroughly 
  • You can smell funny odors
  • The CO2 monitor goes off
  • The unit is loud
  • The heating system cycles often

Any one of these symptoms can be a severe issue. Please call for service immediately before the issues become severe.
