Furnace Replacements & Installations

Keep the heat going when it's needed most.

When it comes to heating your home there are primarily two different ways it is done, through the use of a boiler or through the use of a furnace. The primary different between a furnace and a boiler is a furnace utilizes hot air to provide warmth, where a boiler uses hot water. Pro HVAC provides services for furnace replacements and installations. We have the experienced technicians to ensure your old furnace is removed and new furnace is installed in a timely manner.

Have a boiler, not a furnace? Take a look at our boiler replacement and installation services.

If you need HVAC work done this is your company! We needed emergency work on our furnace. We called a dozen companies and went with HVAC pro. The problem was much more complicated than we anticipated but they fixed it, were gracious, explained the situation and charged a VERY reasonable price. So thankful we went with HVAC Pro!

Jeremiah is an outstanding contractor. I work with a lot of people in the trades and he is by far the best. Working with residential to commercial types of units - he knows it all. Does a great job and finishes promptly. I only recommend Jeremiah when colleagues are looking for HVAC work. I highly recommend Pro HVAC and will use or recommend anyone else.
