How often should I service my heating and cooling equipment?
An annual tune-up for your furnace and air conditioning system will be sufficient. Your furnace equipment can be tuned up any time of year and does not have to be done before the start of the heating/cooling season if you keep up with regular maintenance. Air conditioning tune-ups need to be performed when the outside temperature is above 60 degrees.
Which heater is better: a furnace or a boiler?
The right heating system for your home depends on several factors. For starters, the size of your home needs to be taken into an account. And the existing building insulation may affect how well each system works. Ask Donovan & Jorgenson HVAC technicians to find the best heating unit for your house.
