Heating & Cooling FAQ

What is the life expectancy of my HVAC system?

How often you run your system, the system’s age, its make and model, and whether or not it was serviced regularly over the course of its life can all play a significant role in how long your system will last you.d/or air conditioner to last approximately 15 years.

What is a Heat Pump?

A heat pump is part of a home heating and cooling system and is installed outside your home. Like an air conditioner such as central air, it can cool your home, but it’s also capable of providing heat. In cooler months, a heat pump pulls heat from the cold outdoor air and transfers it indoors, and in warmer months, it pulls heat out of indoor air to cool your home. They are powered by electricity and transfer heat using refrigerant to provide comfort all year round. Because they handle both cooling and heating, homeowners may not need to install separate systems to heat their homes. In colder climates, an electric heat strip can be added to the indoor fan coil for additional capabilities. Heat pumps do not burn fossil fuel like furnaces do, making them more environmentally friendly.

Why are Heat Pumps more Efficient?

Heat pumps are one of the most energy efficient HVAC systems available on the market because they don’t burn fuel to provide heat. In addition to their high efficiency, they can operate as both a heating and cooling system, thus reducing the number of systems that require maintenance, repairs, and replacements.

Do I need HVAC maintenance?

Regular maintenance is incredibly important for a well-working, energy efficient heating, ventilation, and air conditioning (HVAC) system. An annual tune-up conducted twice a year, once for heating and once for cooling, can help you enjoy better indoor comfort all year long.
