You probably wouldn't get a brand-new car and assume to never have to inflate the tires, change the oil and examine any atypical 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 maintained properly and routinely, even the best heating and air conditioning equipment could experience complications and become less 'fuel' efficient over time.
