Very proffesional and fast. He even called me back two days after the repair to make sure it was running correctly. Best service I have ever hired. I will only use A &D Heating and Air Conditioning for now on.
Started with two water heaters and changed to one due to cost. Never heard from them again.

They were on time for the estimates and the installations. I was told what they would do and they did it. Cleaned up after themselves. This is the second house they installed a new heating/AC unit for me. I've used them twice and will use them again.
Went above and beyond what I expected. Performed the water heater service and did a visual inspection of the whole house plumbing system. Made some very good suggestions for improving and optimizing my system. Would hire him again, if needed.

Costs depend on system age, type, labor, and whether part replacements are necessary.
The most obvious downside is the high upfront cost of buying and installing one of these systems. Additionally, sometimes the system can take a longer time to heat than alternatives like a boiler. Also, if something goes wrong with the geothermal pump, repairs are often significantly more expensive than repairing traditional, above-ground heat pumps.
Service costs range from $200 to $1,500, depending on maintenance needs, system age, and labor.
There are three main types of heat pumps. An air-source heat pump system is the most common and has two parts—an indoor air handler unit and an outdoor heat pump unit. A ductless heat pump system functions similarly to an air-source heat pump system but doesn’t need ductwork to distribute the air. A geothermal heat pump system pulls heat from the ground to help heat your home.
Geothermal systems provide energy efficiency, lower utility bills, and long-term sustainability with minimal environmental impact.
