Heating Installation Starts with a Load Calculation

Most heater replacement projects require two appointments: a consultation to evaluate your needs and the actual installation date. These appointments can be made within a few days of each other if we have the unit you need on-hand, allowing you to enjoy your new heating system without having to wait.

During the consultation, our service technicians will conduct load calculations to see what size unit you need. This ensures that you choose a unit that is large enough to heat your home but small enough to heat it efficiently. Our calculation takes your house size into consideration while also factoring in your insulation, placement toward the sun, and use of windows.

We Recommend Units of all Makes and Models

At Three Rivers Services, LLC, we pride ourselves on our knowledge of different HVAC brands. We learn about every new model on the market and know what sets it apart from the rest. This allows us to make informed, unbiased product recommendations to our customers. We will always encourage you to do your own research and choose the make and model system that is best for you, but we will also provide our recommendations and explain why we made them.
