Furnace Installation

Furnace Installation

Modern furnaces have many benefits over older furnaces. First, they are energy efficient, which helps drop the cost of heating your home or business. That cost savings can help the furnace pay for itself over its long life. 

If your home is ready to upgrade to a modern furnace, contact Welsch Heating & Cooling. We offer professional furnace installation that is fast and accurate. Also, check the financing options we offer to help cover furnace and AC installation costs.


Should You Replace Your Furnace?

There comes the point when every furnace will require replacing. Sometimes the constant breakdowns cost more than replacing the furnace. Other times, the energy efficiency of a modern furnace makes more sense. 

St. Louis’ winters are unpredictable and often cold, which means you need a furnace you can rely on throughout the cold season. Finally, replacing an old furnace gives you peace of mind that your home or business will be snug and cozy all winter long. Here are some signs you should replace your furnace.


The Unit is Around 15 Years Old

With regular maintenance, a furnace can last between 15 to 20 years. If your furnace is over 15 years old and starting to require repair calls, it is time to replace it. 


Carbon Monoxide Leak is Present

Carbon monoxide leaks are dangerous. If your current furnace produces CO2 inside the home or business, it needs replacing. Also, if your CO2 monitor has gone off, then CO2 levels are dangerous and you should exit the house and call a professional.


Soaring Heating Costs

When the monthly heating bill starts to rise, it may be a sign that the furnace is burning more gas or using more electricity to heat the home. That level of inefficiency costs homeowners and businesses a lot of money each year. Replacing the furnace with a modern, energy-efficient model is a smart way to save money each month on your heating bills. 


Your Home is Abnormally Dusty

Generally, furnaces do not create dust. However, if your home is abnormally dusty, there could be a problem with the ducting. Poor ducting installation can lead to loss of heated air and infiltration of dust and particulates. 


The Furnace has Suffered a Complete System Breakdown

If the furnace is broken, it may be time to replace it, especially if the unit is over 15 years old or if the number of repair calls rises. Welsch Heating and Cooling offers fast and efficient furnace replacement.


How to Prevent Furnace Breakdowns

Eventually, every furnace will break down, usually because of age or poor maintenance. Maintenance is the key to extending the life of a furnace. You invest in the capital purchase of a new furnace by keeping the unit maintained. 

When furnaces or heating systems are not maintained, that eventual breakdown happens sooner. Not only does the lack of maintenance cause breakdowns to occur, but it also shortens the life cycle of the furnace and can void the warranty. 

To extend the life of your existing furnace, add a yearly maintenance service call through Welsch Heating & Cooling. Doing so will help keep your furnace running smoothly and keep energy bills in their normal range. 


Financing Options for Your New Furnace

Furnaces tend to break at the most inopportune time. To help overcome that hurdle, Welsch Heating & Cooling provides access to consumer lending sources, which can help finance a new furnace and its installation. 

Thanks to our partnership with Synchrony, our customers can apply for Promotional Financing for capital expenditures for their homes. The application process is easy, fast, and secure, with a decision given in a few minutes, and you can apply from the convenience of your home or office.
