"I had a Trane A/C installed by air systems. Carlos and his crew were on time, worked very efficiently and finished the installation within 1 day despite having to widen the attic opening. They cleaned up carefully and were professional in their communication. Also, their price was about $1000 less than the closest competitor. Would definitely hire them again!"

Heating Oil questions, answered by experts
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.
You can expect a geothermal system to last for years. According to the Department of Energy, the underground infrastructure for the heat pumps lasts about 25 to 50 years, which includes the pipes buried in the soil. The actual heat pump itself has a life span of around 25 years.
Costs depend on system age, type, labor, and whether part replacements are necessary.
There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.
Most maintenance checks take 2-5 hours, though extensive repairs may take longer.
