Gas vs. Electric Furnaces

When choosing the right heating system for your home, it’s vital to consider the differences between gas and electric furnaces to select the best option. Both are excellent home heat sources and require similar annual maintenance to ensure efficiency. The difference is primarily in their source of energy. A gas furnace utilizes fossil fuels to use combustion to create heat, whereas electric furnaces use electricity through heating coils. The difference in cost to install and run these two systems is often negligible as both are excellent and energy-efficient choices.

Jake came and did my spring service yesterday. Their service is very professional, they are always out to get the best deals for anything I may need. I purchased new units from them a couple years ago, and the savings has been so noticeable.
