One Hour Heating & Air Conditioning is the nation's first heating and air conditioning service company to promise that we're Always On Time...Or You Don't Pay A Dime! Everyone at One Hour -- from our schedulers to our service technicians -- respects the value of your time and your home as your castle. That's why if our technician doesn't show up on time...doesn't use floor savers in your home...doesn't wear Floor Savers to protect your floors...and doesn't clean up after he's solved your problem...your One Hour service is free. We mean it when we say your satisfaction is 100% guaranteed. One Hour Heating & Air Conditioning is unlike any other HVAC service company you've ever used.
