Why is it important to have regular maintenance on my home comfort system? You probably wouldn't buy a brand-new car and plan to never have to inflate the tires, change the oil and check out any unusual noises. Your home comfort system is like 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 have difficulties and become less 'fuel' efficient over time.
