"John was personally referred to me by a friend in the area. Although I do not have the equipment to measure exhaust gas or flue draft, I have always performed my own oil burner maintenance. I hired John this time because I am selling my house and needed to have a qualified professional perform the oil burner service before closing. I left him a phone message on Monday and promptly received a response. We worked together to determine a mutually convenient time for the service. I arrived at the house yesterday and found John and his assistant there waiting for me. They were courteous and immediately began work. I requested that the old parts be left in a bucket and they were fine with that. They were tidy about the cleaning, using a professional soot vacuum that effectively captured all of the dust and odor from the boiler while they were brushing it out. While changing the filter, strainer and nozzle, they captured all of the oil and they attended to some other minor issues with the oil burner and fuel feed assembly that they noticed. They adjusted the draft controller and then used a modern digital exhaust gas monitor to adjust the air supply to the burner to provide proper combustion. They noted to me some possible issues with the quality of the oil I was receiving, but I wasn't terribly alarmed because I knew that I had left the tank nearly empty all summer which is a surefire way to accumulate a good amount of condensate in the bottom. All in all, I feel that John Carragan provided excellent service in a timely fashion, and showed me that he is acting in my best interest. He was not the best price that I received but he made up for it in his responsiveness. The other party beat his price by about $30 but they did not return repeated phone calls requesting an appointment. John was the complete opposite to that, and I am happy that the service was carried out so quickly."

Heating and air conditioning services FAQs
Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an uncertified HVAC pro could lead to poor quality work, costly future expenses, and potential code violations. A certified HVAC technician tackling your home projects protects you as a homeowner.
As you browse our pro listings, take note of the “Angi Certified” badge. Angi Certified 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
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.
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.
