Stay Warm This Winter with Heating Services from Welsch

Being without heat in the winter can quickly become a dangerous situation. While you may add on more layers to keep yourself warm, a house without heat can cause pipes to freeze and burst, which can lead to other pricey repairs. When you’re having heating issues, you can turn to the heating professionals at Welsch.

Furnaces are the most common type of system used in St. Charles area homes. Furnace issues don’t go away on their own, and when you notice something is wrong, we recommend having it addressed right away.

To prevent issues from arising, it’s a smart idea to invest in furnace maintenance services. Our technicians will inspect and clean your furnace to make sure it’s running efficiently and effectively through the coldest parts of the year. A regular maintenance schedule will also increase the lifespan of your furnace.

A well-maintained furnace should last 15 to 20 years. If you start to experience problems, and your furnace is past its 15th year, give Welsch a call to talk about our replacement services. We can hook you up with an efficient model that will help you save on heating costs in the long run.

Some homes don’t have furnaces, and instead have energy-efficient heat pumps to heat and cool their homes. The team at Welsch is experienced in all types of heat pump services, too. Since heat pumps work year-round to heat and cool your home, you’ll want to schedule maintenance service twice a year. If your HVAC system does break down, you can count on us for repair services and new installation if needed.

Signs You Need Air Conditioning Services

Your air conditioning system works around the clock to keep your home cool, so it shouldn’t be a surprise when it experiences an issue now and then. If you notice any of the following problems with your central air conditioning system, call Welsch for help.
No Cool Air

Is your air conditioning system not providing cool air from your vents? Have you adjusted your thermostat up and down but your system is still not cooling? Try resetting your air conditioner at the breaker and see if that helps. If it doesn’t, you should call the HVAC professionals at Welsch.

High Energy Bills

When your air conditioner has to work harder to cool your home to the same temperature you’ve set all summer, you’ll see it reflected in your cooling bills. Sudden spikes are not normal, and repairs or maintenance may help restore your bills to a more comfortable price point.

Loud Noises

Loud noises coming from your air conditioner like banging, buzzing, or grinding are often indications of a malfunctioning part. Let an HVAC technician take a look at your system to find the best way to address these issues.

More Air Conditioning Services

To prevent issues like these from developing, you’ll want to invest in annual air conditioning maintenance. We’ll inspect and clean your system every year to keep it running efficiently all summer long.

Welsch can also help you find a new air conditioning unit when yours is on its last legs. Our professional installation services will guarantee that your system will cool your home properly. If you’ve experienced frequent issues with your air conditioner and it’s over 15 years old, you might want to consider replacing it.

Breathe Fresh Air Indoors with Better Indoor Air Quality Equipment

The air we breathe in our homes is often more polluted than the air outside. Newer homes are built to be very tight, which is good for keeping pollutants out but makes it hard to cycle fresh air in. Talk to Welsch about our indoor air quality solutions to make your home air healthy to breathe. We offer a variety of services to help make every room in your home more comfortable.
