Coldfire Mechanical, LLC is a small business that is known for great service and superior installation at even better prices. We have a reputation for doing Whatever-It-Takes to keep you and your family comfortable and happy. Too often, consumers pay more for their products due to unnecessary overhead costs companies pass on to the consumers themselves. We do things differently. At Coldfire Mechanical, LLC, we focus on minimizing all the expenses that would require higher prices. We pass these savings — usually between 10%-20% — directly to consumers. In turn, consumers receive the highest quality products possible for the lowest price possible. Call us today, and you could save thousands of dollars!

"Great response time and thoroughly explained what we needed, how long it would take and cost of project. System works great and project came in lower than quoted cost and they adjusted cost accordingly. In this day and age it is great to deal with hard working honest technicians."

"Big thumbs up to Ryan and crew! Handled my new install with professionalism and great communication. I took advantage of CT Rebate and Fed Tax Credit and purchased an efficient, 1st model year, high tech system from Carrier. After install there were some minor issues with unit as first year products have. Ryan expedited service of unit and had it operational. And itâ s been running flawlessly ever since. I highly recommend using them and Iâ ve been in the service business for 30+ years and know both good and badâ ¦ they are good! *Side note: Ct rebate program not that good. From what I hear people are not getting appropriate amounts due back to them.. that includes me. You have to keep after them. This is in no way a reflection of Kellyâ s Heating and Cooling"

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.
