"He was not able to perform the service. He told me he did not have the correct parts. That I needed PGE to come back out. I had another professional come the following day and he was able to diagnose and fix both wall heaters with no issue. I was very diappointed and felt cheated."

"Tech said that the Freon leaked out and that the compressor burned out because of it. Quoted $4800 to replace compressor and recharge, or $7,000 for a new AC unit. Got a second opinion and hired a handyman. Turns out the breaker was tripped and needed some fiddling with. AC works great now. Can’t believe they were going to lie about what was wrong to replace the whole AC. Just because it was an old unit. Get a second opinion for them if they tell you something similar."

Homeowners should consider several factors before investing in a geothermal system. If the upfront costs are in your budget and you plan to stay in your home long-term, you’ll likely get a better return on investment. New home construction is also ideal for geothermal heat pumps because these installations often cost less than retrofitting.
The total time it takes to recoup your costs depends on your upfront investment, energy savings, local climate, utility rates, and other factors. Most heat pumps pay for themselves within 10 years, but it can take up to 15 years.
Geothermal installation takes one to six weeks, depending on the system type, site conditions, and installation complexity. This process includes excavation or drilling, connecting piping, and configuring the system, so your contractor may leave heavy machinery and other equipment on site until it’s no longer needed. Assessments for your system may occur several months before the installation.
