I received a new high efficient furnace from NSB and it runs very quiet. I'm very satisfied with…read morethis company. The price was better than the other companies. I called 12 different companies, big names and small names. Other companies offered either high prices with low warranty OR low priced with low warranties. NSB offered Both, Low price and High warranty! Out of all the companies, I'm glad I chose NSB!!! The service was caring, nice and friendly. They came out to inspect fast. No hidden fees like the other companies. The price I paid was the price I was quoted by NSB. This company was HONEST from the beginning!! So many customers are quick to leave a negative comment but rarely do people leave positive reviews. THANKS NSB !!

Originally went to a different HVAC - after buying and installing a "new" thermostat, I was…read moreinformed I needed a new electric furnace. I am a senior citizen on a very fixed income. The electric furnace I had was 11 years old. I called N. S. B. for a second opinion. I should have called Marvin (N. S. B.) first! After testing gizmos and what-cha-ma-call'ems, he found a widget that did not switch off - or maybe it was stuck on? It cost a TOTAL of $180.00 to have Marvin replace the widget and get a new thermostat (the one that the other company sold me did not work). He came back on Saturday to ensure that the furnace worked without problems - he double checked the other gizmos to make sure nothing else was stuck in the wrong position and that the furnace was truly fixed. It was - and four days later - is still silently providing me with quiet efficiency. Marvin saved me from spending over $3400.00 needlessly with that other HVAC company. Great job, professionally done, reasonably priced. I will keep Marvin's number handy!

This last time around, I sent them a video of the issue (loud sound) and they identified the issue from the video then ordered the part. We scheduled them to show up a few days later - the tech who visited us was very nice. He installed the new part very quickly, made sure it worked and went on his way. Very happy we chose Enright for our HVAC system and will continue to utilize their services going forward!

My water heater went out. The company that "diagnosed" the problem charged me $99 and said that…read morethis did not include the cost to replace it. The company then quoted me $2200 as the cost to replace it and reiterated that this did not include the $99 that they already charged me. So yes, had I gone with that company, it would have cost me $2300. Armed with this information, I posted pictures and exactly what the "diagnosis" said and asked for emailed quotes...to be clear I said EMAIL only. I then got no less than 10 phone calls saying "please give us a call so we can talk about your situation. Some called more than once. Lakeland Heating and Cooling (Jason) was nothing like that... $1270 flat rate to replace the water heater. Yes, thats how he replied in his email.. as I requested. He came in.. with the water heater... replaced it... and went on his way. Other companies, that followed directions, also came in higher than $2000. I am EXTREMELY satisfied with Jason and Lakeland! High Quality, Tremendous VALUE

Not only did they perform the install, but took care of registering our units for warranty and submitted for rebates on our behalf. Initially Brian came over to asses our A/C needs and then a team of 4 skilled technicians performed the job over the course of two days. The superheroes were Chris, Ricardo, Steven and Wilfredo. They worked until 10:30pm on very hot and humid days to complete the job. As a Realtor for over 20+ years I've come across many contractors and service providers in my career, but I have never encountered such polite, skilled and dedicated team of technicians.They had to be very creative during install and crawl through very tight spaces or work in a very hot, unvented attic and they all have done so with a smile on their faces. I am truly impressed with this company in every way. Please don't hesitate reaching out to them for any heating or cooling needs. I promise you won't be disappointed regardless what service you receive from them. It will be A+ for sure. Their maintenance service is top notch too.

Harmonic Heating and Air Conditioning is the BEST!!! Our AC…read moredied and after another company told us that our unit could not be repaired and had to be replaced ($6,000), we contacted Harmonic for a second opinion. Daniel the service technician opened the unit up and tested everything. He took the time to explain what he was doing and why. He discovered a bare wire that had been chewed (possibly by a mouse) and was touching the metal housing which tripped the circuit breaker. Daniel replaced the wire and the unit is working perfectly. The honesty and integrity of this company is refreshing. We will not hesitate to use them again and recommend them to all our friends.

Stay away from this business! My entire cooling and heating system was left in an inoperable state…read more I called for a diagnostic of the air conditioner today because cool air isn't coming from the vents. I was told the diagnostic would cost $149. I asked to be informed of any repairs that had to be done. Technician checked the system and recommended replacing unit. We discussed replacement unit and cost. I was ready to pay deposit. In the next 10 minutes I was told that the model I selected is old and not available. New model costs $1000 more. I asked for a proposal to decide later. Technician told me that the visit costs $396. He said that he fixed air conditioner that was not working. He never told me that he is fixing anything. Through our the visit it looked like he was figuring out the problem. I talked to the owner and we agreed that any repairs that were done will be undone so that I do not have to pay for repairs. Then the technician removed all the wires from the board making both heat and fan unusable. He did not just undo the "repairs", but made entire system unusable including fan and heat which were working before his visit. See the photos to show what was done!
