"One Hour Heating & Air has been servicing my HVAC system since I moved to Fort Collins four years ago. Greg Nieves is excellent. He took time to answer all questions and went out of his way to offer suggestions and make sure I understood everything.. This company is totally competent although their prices seem a bit high. However, their service is great and worth the price since I've never had to call them back with a complaint."

"Behold Heating &Cooling diagnosed by furnace issue and correctly recommended a new furnace due to rust and leaks. Their bid was the most competitive and the customer service was outstanding. They were extremely courteous and followed up on all issues. We ended up with a fantastic new high efficiency furnace and new AC units with state of the art controller/thermostat controls. We are very pleased with Gilles and his crew."

"I would suggest you drop all other services and go with this one only. This service man is far beyond the skills and service of all others. I had one show up in car and a back pack. He looked at and said he would send a quote ?????? My furnace is out , its late and the temp outside is 0. Tony Bertolini repaired it less then a hour with no parts. This is a man that knows his S!!! and is more than worth his charges.When the weather starts to warm up I will call him to install a new one . [ I will call no one else .}"
Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.
While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.
The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.
Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
