"So we have a problem with this installation and this vendor is not cooperating to fix a problem with this brand new install. Not only did he not complete signoff which we needed for maintaining our warranty but the testing they did was designed to make us believe it was working when it was not. When we tried to get him out again he pretended to be super busy and all booked out when in reality he did not want to come out on a job he was not getting paid for because we already paid him! In good faith! Under the impression this was a reputable company that would back up their work knowing full well it was a brand new super expensive installation where most of the work was done by my contractor and all they had to do was connect the handlers, test the system and certify it. They would not certify it and made excuses but never returned. It never worked. We can not get them back out to fix it because they've already received payment. BEWARE OF THIS COMPANY. THEY ARE NOT REPUTABLE."

Heating Oil questions, answered by experts

A geothermal heat pump system will take about 10 years to pay for itself, and it has a life span of anywhere from about 25 to 50 years. Installing a geothermal heat pump will cost about $14,250 upfront, but it can reduce your energy bills by around 65% when compared to a conventional HVAC system.

An evaporator or swamp cooler is a common alternative for small spaces. These coolers blow moist air into a space to help cool it down. They are more affordable than misters and use much less water. However, coolers will not have the same cooling effect as misters, cannot help plants survive the heat, and only reach a small area.

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.

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 HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.
