Looking for top-notch cooling & heating service in Boston? Look no further than Joyce Cooling & Heating Inc. With financing options available and a team of experts ready to assist you, we're here to make your home projects a breeze. Contact us today at sales@joycecool.com.

"This is my second experience with Joyce Plumbing and Heating. The first time was a new hot water tank. When you have your local city inspector tell you during inspection of the tank installation that "oh, Joyce did it? Then I don't even need to look at the installation...". That was a ringing endorsement!! We then moved to a mini-split heating/cooling system for our house. These guys were just terrific. We had 3 units put into our house and the team worked flawlessly. From Will (our super human sales guy) to Tina in the Joyce P&H office (customer care) to Calvin and his team, we were very well treated, on time and under budget. I highly recommend Joyce Plumbing and Heating and we will be using them again. You should to!!"

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.
