Heating & Cooling FAQ

Life expectancy

A standard life expectancy of your cooling unit is 12-15 years, depending on several factors such as proper designing, right sizing, tactful installation and most importantly, periodic maintenance. Neglecting any one or more of these factors, you can end up with exorbitant repairs or early replacement of the unit

What is a heat pump

In a nutshell, an HVAC equipment that gives you both heating and cooling is called a Heat Pump. They transfer heat energy from one area to another by using its refrigerant cycle, thus making your house cooler in the summer and warmer on the winter giving you a year-round comfort.

Do I need HVAC maintenance

Just like any other mechanical system our HVAC system also comprises Of multiple components and connectors. A periodical maintenance service of these sensitive component is an unavoidable task. A regular and preventive maintenance of our heating and cooling units can not only increase the lifespan of the system but also saves tons of money on our energy bills. For the residential HVAC system, it is recommended to get tune up service for atleast twice a year. On the other hand, for the commercial units should have atleast four times maintenance service in a year.
