 Trustindex verifies that the original source of the review is Google. The tech who came out to clear drip line from ac unit was great and very efficient. Would use their service again if needed.  3 text messages for this survey in a week seems a little heavy. Doing this to stop the text messages.

 Trustindex verifies that the original source of the review is Google. What a great company this is. I called at 3:00 on a Friday afternoon and they had a tech in my area who was there at 6. He quickly diagnosed the problem and got us up and running again. Very friendly and professional all around. I highly recommend and will definitely use them in the future.

Still Have Questions? Let Us Help

What is a dual fuel HVAC system?

A dual fuel system combines an electric heat pump with a gas furnace. The heat pump handles heating efficiently in mild and moderately cold weather, and the furnace automatically takes over when temperatures drop to the coldest extremes. You get the efficiency of a heat pump with the power and reliability of gas heat.

How does a dual fuel system save money?

The system automatically runs whichever heat source is most economical at any given temperature. For most of the season, the efficient heat pump does the work, and the gas furnace only runs when it's truly cold. This balance typically delivers the lowest possible heating bills for homes with gas available.

Is a dual fuel system right for my home?

Dual fuel is an excellent fit for homes that already have gas heating and want lower bills without giving up cold-weather reliability. It's ideal for Maryland's mix of mild and freezing days. We'll assess your home and existing equipment and give you an honest recommendation.

Does the system switch between heat pump and furnace automatically?

Yes. A dual fuel system uses smart controls to monitor the outdoor temperature and automatically switch to whichever heat source is most efficient. You don't have to do anything — it manages the balance for you to keep your home comfortable and your bills low.
