Hybrid Heating Systems in Bellevue, WA

We think heat pumps are one of the best ways to enjoy comfort in a home in Bellevue, WA. With a heat pump working in your home, you have your indoor climate needs taken care of for any season. A heat pump delivers energy-efficient heating for winter, and then switches over to work as a powerful air conditioner during summer.

But the way a heat pump operates can sometimes make it lose efficiency in winter. There’s a way around this problem, which is to install a hybrid heating system, a type of heat pump that uses dual sources of fuel. S&L Mechanical Heating and Cooling works with these dual fuel hybrid heat pumps: installations, repairs, replacements, and maintenance.

How Does a Hybrid Heating System Work?

It isn’t much different from a standard heat pump. A heat pump circulates refrigerant to move heat from either inside the home to the outside, or outside the home to the inside. Under most circumstances in the winter, a heat pump has no problem drawing sufficient thermal energy from the outdoor air (there’s always some heat in the air, no matter how low the outside temperature). But a heat pump may run into an especially chilly day when it must work harder to draw sufficient heat into the house.

A hybrid heat pump simply adds a backup heater—usually a gas or propane furnace—to the heat pump that can leap in when it’s needed. The second heater will only run for as long as necessary to maintain heat pump energy efficiency, then automatically turn off.

Is a Hybrid Heating Installation Right for My Home?

This is the Big Question—and it’s one of the reasons to always work with a professional HVAC contractor if you’re debating installing a heat pump. Current heat pump technology makes the units effective in extremely cold temperatures, so going with a dual fuel heat pump may not be necessary. But every home has different requirements for comfort, and we recommend you consult with our heating professionals about whether you should have a standard heat pump installed or a hybrid one.

Dual Fuel System Repairs and Maintenance

A hybrid heat pump may need occasional repairs. Because they combine a furnace with a heat pump, it’s crucial to have trained HVAC technicians for any repair work. The balance between the heat pump and the backup system is vital for you to get the most from the system. Our technicians are available 24 hours a day to help you with any dual fuel heat pump problems you run into. Make sure that you sign up for our regular maintenance program so your hybrid heat pump receives its twice–annual inspection and tune–up.
