Furnace and Heating Energy Saving Tips
The heating and air system of a home uses more than half of the energy. However, in order to save money this large expense there a number of things that don’t cost much or any money to reduce this monthly expense. The biggest thing to realize is that the homeowner is the one in control of the thermostat settings! Just by changing a few habits can save some initial money too. You may be cooling your home, but the fossil fuels you’re burning in the process are only making your summers hotter. Also, in the big picture of cooling the inside of ones home consists of keeping the cool air in and the hot sun out.

"Back in the beginning of the summer of 2013 my original AC in my house after 18 years finally lost its compressor. When I called the service company they indicated that it would be difficult to replace, cost almost as much as a new AC unit, and take a long time to order it. At the time I only had one system in my house, and it never really did an adequate job of cooling both the upstairs and the downstairs. As a result we usually ran up to 3-4 additional fans to help circulate the air. I decided after much debate to replace this system with two new ones and began to solicit quotes for the job. Over the course of 4 days I received bids from 5 different companies, one of which was from Rodney of Gene May HVAC. He was recommended to me through  a relative. By the time I completed all negotiations back and forth with each company, Rodney offered me the most competitive cost, highest rated equipment, and fastest installation. Keep in mind this started on a Saturday, and now it was Thursday. My wife was threatening to leave if I did not do something soon. So in order to finalize the deal, Rodney agreed to have the entire job completed by the following Monday. He said his crew would work through the weekend beginning Friday morning to get this done. He lived up to all expectations. All the demolition was completed by Friday, and both new AC systems were running by Saturday afternoon. The furnace install and all new ductwork were then completed on Monday and the quality of the entire installation was top notch all the way. The system worked as advertised. We have never had air circulation and temperature control like this since we built the house. If you are looking for an HVAC company you can depend on and deliver on their promise call Gene May."
