Why is it important to have regular maintenance on my home comfort system? You probably wouldn't get a brand-new car and plan to not ever have to put air in the tires, change the oil and check out any atypical noises. Your home comfort system is the same as your car’s engine; it’s a mechanical device with a motor, electrical components... and even fuel. So it is essential to have routine maintenance of your home comfort system by a qualified technician. If not properly and routinely maintained, even the best heating and air conditioning equipment could cause problems and become less 'fuel' efficient over time.
