A Family Company Working for Your Family

Richard Weis began installing central heat in homes after he returned from World War II. His brother, Raymond Weis, joined the company in the mid-1950s and was instrumental in evolving the company. Weis Comfort Systems opened its doors on Jan. 1, 1975. Raymond’s two sons took over when their dad retired. Tom and Dan still lead the company.

Our family tradition is to keep our Maryland Heights, MO neighbors comfortable by providing professional craftsmanship, warranties, and value.

Importance of Regular HVAC Maintenance in Maryland Heights

You change the oil in your car and rotate the tires. You update the operating software on your computer. Regular maintenance helps your car and computer run more efficiently and can prevent headaches and frustration. The same is true with an HVAC system. Air conditioning and heating systems should be serviced once a year for the best results.

Benefits of annual maintenance include the following:

  • Finds small problems before they become big problems
  • Fewer system breakdowns
  • Improves system efficiency
  • Extends the lifespan of your system
  • Provides better indoor air quality
  • Lowers utility bills

The optimal time of the year to schedule HVAC maintenance is in the fall. During the fall season, we are past the heat of summer but haven’t been hit with the deep cold of winter. Having your system tuned up in the fall means you’ll be less likely to have an emergency heating issue in the winter and you’ll be ready for spring and warmer temperatures.

Extend Your HVAC Lifespan with Expert Repairs

Sometimes things break, and usually at the least convenient time. Fortunately, Weis Comfort Systems is available around the clock, seven days a week for emergency repairs.

Over time, mechanical systems wear down and parts need to be replaced. Sometimes repairs are simple, and other times the fix is more complicated. Either way, our team of certified and trained technicians has the know-how to get the job done.

Our experience covers a wide range of HVAC equipment:

Top-Quality HVAC Installation & Replacement

If your Maryland Heights, MO home or business heating and cooling systems are more than 10 years old and need repairs often, it might be time for a new system. An older furnace or boiler can have an annual fuel utilization efficiency (AFUE) as low as 56. According to the federal Office of Energy Efficiency & Renewable Energy, that means almost half of the energy consumed to operate the system is wasted and does not turn into heat in your home. Similar inefficiencies are found in cooling systems, too.

Newer heating and cooling systems have much higher efficiency, break down less often, and result in lower energy costs.

Age isn’t the only clue that it’s time to consider a new system. Other warnings to replace your HVAC includes the following:

  • The equipment is making loud noises.
  • There are funny smells when the system is on.
  • Some rooms are hotter or colder than others.
  • Your energy costs keep going up.
  • You notice leaks around the equipment.
  • The system continually cycles off and on.

Installing and completely replacing an outdated system is not cheap but has immense value over time. A new system also increases the value of the home. We offer flexible payment and financing options to help your new system become a reality without wrecking your budget.

Breathe Easier with Air Purification

Most of us spend most of our day indoors. Even those who work outside often spend half their day at home.

According to the Environmental Protection Agency, the long-term effects of poor indoor air quality can be quite serious. Studies have linked lung disease and certain cancers to indoor air contaminants. We may not always see the harm, but indoor air pollutants are often two to five times higher than outdoor levels.

Possible indoor air pollutants include the following:

  • Fiberglass
  • Asbestos
  • Formaldehyde
  • Solvents
  • Pesticides
  • Dust Mites
  • Bacteria
  • Perfumes
  • Second-Hand Smoke

Physical symptoms can begin to manifest. Fatigue, headaches, allergies, coughing, dizziness, respiratory problems, and nausea can all be caused by harmful qualities in the air we breathe at home.

Weis Comfort Systems offers several solutions to improve indoor air quality:
