"Overcharged by WAY too much. The hydrostat charge was $862.90, and they installed a different brand than was on the invoice. The cost on Amazon for that unit is $188. Taco Zone Valve charged $745.56: valve on Amazon: $134.00 Same with other charges $3609.80 total. Less than 3 hours labor x 2 guys... who showed up late in the day when they scheduled for the morning."

Heating Oil questions, answered by experts

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.

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.

Your HVAC manufacturer will give you instructions on how often you should service your system. Have your unit professionally serviced at least once a year when in doubt. 

Heat pump systems are different because they provide heating and cooling solutions for your home. In this case, you should have it serviced at least twice a year.

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.

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.
