"This company preys on the unassuming. Their reps propose outrageous services (and prices to match) that ultimately may not be needed. We were told over $1,200 absolutely had to be completed. I asked for a service manager to call and explain. No call ever came. A second opinion completely refuted Total HVAC's claim. In turn, we saved $1,200 from 5 minutes of additional due diligence. The real kicker is their silly $16.90 per month fee for the "service plan". This is an absolute annoyance and frivolous bill that only adds subscription based income to their bottom line - no real value! Their accounting department threatens with outlandish finance charges and fees. So glad we are no longer reliant on the foolishness of their predatory practices. Stay away!"

Heating Oil questions, answered by experts

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.

For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement.

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.

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.

HVAC systems usually last between 10 and 30 years, with most having a lifespan of around 20 years. Factors that impact a unit’s life expectancy include which brand you choose, how often you use it, and how well you maintain it. To make sure yours lasts as long as possible, make sure to keep it clean and schedule an annual service with an HVAC technician.
