"Excellent service from my first call to Hope and then Linda who explained in complete detail what would be required to service my air conditioner and the cost. The servicemen, Branden and Jose, were very professional and went over my HVAC unit completely. The only access to the unit’s condenser coil is from the outside which needed to be cleaned/hosed down. I’m in a 3rd floor condo which requires an extension ladder to reach. Most HVAC service will not go any higher than 25 feet but the Shavitz servicemen had no problem reaching my unit which is approximately 35 feet up. Price for the service was a little higher than I expected but I fully understand after observing the work done. I will highly recommend Shavitz to others in my condo building including our building manager and also anyone who is in need of HVAC service. Great service from my initial call thru service completion."

"Vinny came over to my home the same day to give an estimate as I needed to replace my exisiting humidifier. I already knew it wasn’t working and super old so best to replace it. He explained everything to me when looking at my furnace room. Explained the different size and efficiency of the various models I could use with the size of my home. Quick to schedule installation as well :) I will definitely use this company for future HVAC needs!"

"They came early in the morning for a new HVAC install. Everything went well. They were neat and clean. The price was well below a comparable system from another company. They provided several options to replace out ageing HVAC system"

"The Besco team (sales, service, customer service) was a breath of fresh air for us. We purchased an older home and have had a series of mechanical issues (AC / Furnace) and recently had to replace our hot water heaters. The sales team was very helpful in outlining our various options in a low-pressure approach. The install team was exceptional in that they guys were willing to modify their placement of the unit so that we could use the (now) unused space for other (read: storage) purposes. This took add’l time and also required them to do a little additional work to make it work best for us. THEY DID THIS WILLINGLY BECAUSE IT MADE SENSE FOR US!! If you require anything HVAC / mechanical work for your home, please do not hesitate to engage Besco - you will not be sorry!"

"I had a great experience with their HVAC services. They repaired my electrical baseboard heater quickly and made sure everything was working perfectly before leaving. The team was professional, punctual, and very knowledgeable. They also installed our new central A/C system smoothly with no issues at all. Communication was clear throughout the process, and the pricing was fair. Highly satisfied with the quality of work and customer service. I would definitely recommend them for any heating or cooling needs."

"In May of 2021, CR Mechanical replaced our HVAC equipment (furnace and AC), and installed a new air scrubber and an ecobee thermostat. We were very satisfied with their work (exceeded expectations), and Craig is an excellent installer (that was most important to us). The ecobee was defective out of the box, and he reinstalled our old thermostat and was back the next day (as promised) to install a replacement ecobee. Everything works great."

Heating and Air Conditioning FAQs, answered by experts

The cost to install a ductless mini-split AC system ranges from $2,000 to $14,000, depending on the type of unit, the number of zones or rooms, and the complexity of the installation. On the low end, a system for one or two zones in a single room costs around $2,000. Covering two zones for more rooms can cost between $6,000 and $8,000. For a larger multi-zone system to cover an entire home, costs can be $14,000. If you don’t already have an AC system in place, you may need to add the cost of permits, an electrician, and a concrete pad.

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.

To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Some units have a dedicated "reset" button; if yours does, press and hold it for three to five seconds. If your air conditioner doesn't have a reset button, or if you are resetting it after a power outage, leave the circuit breaker off for at least 30 minutes to allow the system to reset itself. Afterward, turn the power back on at the breaker, turn on the AC from the thermostat, and set it to "cool" to test the system.

When your HVAC system is loud, a few different causes are possible. If you have loose connections or bolts in the hardware, they can rattle as the system runs and vibrates. If you have an extremely dirty furnace filter, it could cause the system to generate noise. More commonly, an excessively loud HVAC system indicates a malfunction in the system. You may have a blower motor that is close to failing or a compressor that is breaking down. These issues require an immediate inspection.

No. Your furnace does not run your air conditioner. Both units use the same system of ductwork to move conditioned air throughout your home, but you can have a furnace without having an air conditioner and vice versa. Furnaces are only for heating your home. You can buy a system that does both, however, like a split system or a heat pump (yes, heat pumps cool, too).
