In order to understand the needs and expectations of our customers, we take great care to work and communicate, with every customer in a professional manner.

"TLDR: This is a great plumbing company and Harris is my current go-to trustworthy plumber. I highly recommend you give HG a call for an estimate if you need plumbing work. I really loved all the work, and I'm rather difficult to please. My experience (over last few months in 2024): HG Plumbing installed our new hot SS water storage tank, a new toilet for a 1/2 bath, and a LG steam washer and dryer (GAS) in our new laundry room. Harris also added a new dryer exhaust vent to bring us up to code, which was quite tricky due to the how the old (incorrect) vent was run, and he came up with a great customized solution for us, which none of the other three plumbers I met with suggested. 10/10 on ALL the work. Harris and his team was on time, easy to communicate with (text/phone/email--he responds to everything!), PROFESSIONAL, and cleaned up nicely after themselves. Plumbing on the North Shore feels very expensive and HG prices are actually reasonable for the area, especially considering the excellent quality of the services. Invoices are up front and clear and Harris is extremely knowledgable, personable and easy to talk to (answered all my questions and concerns--and had many). We discussed whole house water filtration and few other upgrades done the line, and Harris is an amazing resource on all things plumbing and local/code issues. For those with MCS or healthy home concerns: I have sensitivities to many home improvement odors/chemicals and Harris was very understanding and respectful of this. Even the caulk he used was low VOC and finished off gassing extremely quickly. Normally I take 3-4 estimates before committing for non-emergency/maintenance work, but from now on I'm just calling HG. Done right is everything in plumbing and much more cost effective in the long run."

Heating and air conditioning services FAQs

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.
