Appliancezone.com is a leading on-line retailer of appliance parts and accessories for do-it-yourself homeowners. Incorporated in 2008, it was started by CEO, Jim Allen and his wife Paula, who operated an appliance repair business for nearly fourteen years prior to starting the internet company Appliance Zone.

"This is the first online review I've ever written -- my experience with this company was that bad. Three aspects that deserve attention: 1) I placed an order and tried to cancel six minutes later. Turns out they don't accept cancellations. 2) I couldn't find a phone number, so I had to work the return/refund by email. The exchange was painful -- so unhelpful I felt like I was interacting with a bad chatbot. 3) I ended up eating shipping costs (expected) and got hit for a 50% restocking fee (unexpected) because I refused the package instead of paying to ship it back. Didn't matter that it went to the correct address, was clearly labeled, and had prior return authorization. So I ended up with a $21 refund on a $60 order, and a lesson learned about where not to buy appliance parts."

Armstrong is a family owned and operated air duct cleaning and chimney service business. With over 45 years in business, we are one of the oldest, largest, and most experienced air duct cleaning and chimney service companies in the United States. Our customers range from residential, to institutional. We service many large property management firms, housing authorities and cleaning contractors. Our clients include some of the finest and well-known companies and buildings in Northern New England such as Dartmouth College, Phillips Exeter Academy, University of New Hampshire, Harvard Historical Society, U.S. Coast Guard, FedEx, Target, and Walgreens. This level of achievement only comes with years of hard work and an ongoing commitment to create and adopt industry innovations and standards.

"Repeat customer who has been mistreated. Scheduled a pellet stove service appointment and had to wait a couple of months. The pellet stove was installed a few year prior by Armstrong. Stove was fully functional when tech arrived and when work was wrapped up the stove didn’t work. Tech on his way out mentioned the office would reach out to me with next steps. Dealing with single digits temperatures out door any little thing helps and now have a broken stove that doesn’t work. Two days later I hadn’t heard from their office so I sent an email inquiring what the next steps were. The admin responded stating the operations manager had our paperwork on his desk and that I am on the list. A day after that I decided to call for some information and admin gave me more of the same stating “work order is on my bosses desk, he will get back to you in a couple of days”. After persistence on my part I decided to track down the ops manager and he gave me a long story on why they weren’t communicating and basically stated again I wasn’t top priority. As a customer you shouldn’t feel like you are bothering a business that you just spent a ton of money on to get something fixed that now doesn’t work. Armstrong years ago was different and today my experience is very sour. Maybe too much business has impacted their customer service? Maybe new employee vetting is the issue? Maybe it’s the management? It’s sad to see customer service like this. Please beware.. you will reach out for help and you may or may not get it. Pay quoted money now but you’ll be back burnered the moment something else comes along."

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.
