He told me exactly how much the new valve would cost before leaving to get the new one. The price seemed reasonable and I agreed to it. I assumed that was the price of the part with no labor.

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.

"I delayed writing this review to give Anderson A/C ample time to deliver the high-quality work I expected.
A brand new system was installed, but a series of issues followed upon completion of the project. First, the dehumidifier didn?t work due to an improper wire connection. Then, the A/C unit began dripping water into the emergency drain pan because of a misconnected drain pipe. Later, the P-trap started leaking water into the attic.
The quality of Anderson A/C?s workmanship declined quickly?and unfortunately, so did their reputation in my eyes.
The staff were friendly, which is why I?m giving them 3 stars instead of just one."

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.
Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.
Yes, geothermal heat pumps are worth the money. You can save about 70% on heating costs in the winter and around 50% on cooling costs in the summer with a geothermal heat pump compared to a traditional HVAC system. Over time, your savings on monthly utilities will pay for the cost of the geothermal heat pump installation. If you have an incredibly small yard, however, you may not have enough space for this type of system.
If a geothermal heat pump is installed correctly, then you shouldn’t have to worry about having a backup heat source such as a furnace or oil boiler. However, there are geothermal systems installed that include a backup in case the heat pump fails due to extreme cold. This is simply a backup heat pump you’ll likely never need and not an alternative heat source.
Geothermal systems provide energy efficiency, lower utility bills, and long-term sustainability with minimal environmental impact.
