Q: Why should I purchase a new heating or air conditioning system?

A: At D.C.V Proulx, we realize that purchasing a heating or air conditioning system is no small matter. However, if your existing system is old, in need of repair or simply inefficient, purchasing a new unit, one which can be as much as 60% more efficient than a system purchased just 10 years ago, can turn into a long term benefit. Rather than continuing to pay for ongoing maintenance and costly monthly bills, invest in a new system today that will save you money for years to come.

Q: How long will my system last?

A: Maintenance and service play a key role in the lifecycle of a heating or air conditioning system. If all recommended maintenance and service actions are taken, it is believed that an air conditioner should last 12-15 years and a gas furnace should last from 20 to 25 years.

Q: What can I do before calling someone to service my system?
A:
  • Disconnect your indoor and outdoor switches.
  • Make sure your circuit breakers are in the ON position.
  • Make sure your filters are clean.
  • Open supply and return vents and make sure they are unobstructed.
  • Double check both indoor and outdoor disconnects switches.
  • Check the settings on your thermostat.
  • Make sure the system switch is on the appropriate COOL or HEAT setting.
  • Have the FAN switch on for a continuous vent.
Q: What happens when I replace my old system?

A: To install the most efficient HVAC system in your household, a detailed inspection should first be performed by your installation contractor. The inspection by your contractor should include, as a minimum, the inspection of your home’s ductwork, insulation, refrigerant piping, electrical service, wiring, thermostat, condensate piping, flue piping, flue terminations, chimney liner, slabs, filter, driers, registers, grills, drain pans and evaporator coil.
