"I signed up for a service plan, as I’m not much of a handyman myself. They had a variety of payment options with the service plan, so I was able to start monthly payments, which works best for me. Our service person was polite, and he explained everything in terms I had no problems understanding. I had an additional issue with an attic duct being chewed through. He got up there and got pictures right away so they could put together an estimate. Same visit, no hassle. And because of the service plan, there was no charge for the system check. I just let him in, showed him around, and he worked his magic. No regrets here. There’s a very good chance I’ll just keep up this service plan for the entire time I own my home."

While geothermal heat pumps are an energy-efficient option for heating and cooling your home, you may find that after a period of time, things don't work as well as they did when the geothermal heat pump was first installed. There are some common issues that you can look for before you call in a professional, and some things you shouldn't try to handle yourself.
If you're in need of a new heating system for your Northeast Indiana home, consider a hybrid heat dual fuel system. These combine the efficiency advantages of heat pumps with supplemental heat from a combustible fuel, typically natural gas. Air-source 
Duct sealing is one of the easiest and most effective ways to improve your HVAC system's efficiency. In the average Indiana home, around 20 percent of conditioned air is wasted due to leaky ducts.
