"First I would say setting the appointments was easy. I called on Monday, they had times available on Tuesday. It was very easy. In addition, I was sent an e-mail and called when each guy was on his way. The e-mail contained a picture of the repairman with a bio. I thought that was a great touch. The HVAC guy was great. He was on time, looked at what I was asking, quoted me a price ($120) and completed the work. It took him less than an hour. I thought the price was fair. I would rate the HVAC an A. The Plumber is really why they received an overall grade of a C. The Plumber was a very nice guy, there were no issues there. He arrived within the allotted time. He arrived and I showed him the dishwasher and disposal. Our dishwasher backs up from time to time where there is water sitting in the bottom of the dishwasher after the cycle is done. We explained it doesn't happen often. We also had concerns with garbage disposal. He explained this happens from time to time with all dishwashers and that the disposal was fine (he said it was a top of the line disposal so very quiet - we didn't install the disposal - was there when we bought the house). I then asked him to tighten down a loose shower/bathtub knob. He said he fixed it the best he could, it was still a little loose. Then, after the "work" was complete - he said it was $220. Thank goodness there was a $30 Angie's List coupon! I was shocked, I didn't really know what to say. He never quoted me a price before any "work" was done, he was there for maybe 40 minutes (half of which he was chatting). He basically did nothing to the dishwasher/disposal and he didn't even fully fix the bathtub/shower. Looking back I wish I would have objected more to the price, shame on me! I guess I was in disbelief about the price? I would recommend B & D for HVAC but definitely NOT for plumbing. They are incredibly expensive. FYI, the person that booked the appointment said there was a $50 service fee but that would be a credit for any work done. The repair person was supposed to give a quote before any work was done. I feel somewhat taken advantage of."

"Excellent!! We were so impressed by Cory and amazed he and his team could perform work the same day. Husband and I relocated to Wisconsin from Alaska in June 2018. Hot water heater in house we bought brand new 9/2017. It broke and warranty didn’t transfer to new owners. Cory commented install in old unit not done by professionals. When work completed on new unit, it was like comparing a duct taped wreck to a sleek sports-car ! Excellent Plus job!! Cannot say enough thanks for kindness to us, Husband and I of 48 years feel Blessed Cory was our Professional. ?"

"Dean's removed a large nonfunctioning halogen ceiling fixture with a small simple LED fixture that I provided. More importantly, Dean's replaced my electrical breaker box and all of the breakers and added a main shut off in the box so I don't have to run downstairs to the electric meter room to completely shut off my electricity. It wasn't cheap but well worth it. They also added a separate circuit and breaker for my bidet which was tripping the breaker hallway through the cycle, leaving me fumbling in the dark looking for my flashlight. I highly recommend Dean's!"

FAQs for heating and air conditioning service projects in Buffalo, MN

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.
