Why is it important to have regular maintenance on my home comfort system? You probably wouldn't purchase a brand-new car and plan to never have to add air to the tires, change the oil and examine any unusual noises. Your home comfort system is similar to 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.
