Positive: Professionalism Had a terrific experience with my service technician, Harry Yan. First off I was able to make an appointment the same day and Harry came to my house within the time frame. I had originally had another technician come last week and they informed me that I had to replace my entire furnace due to the malfunction of the heat exchange. On top of that they were going to red tag my furnace and shut it off unless i got someone to replace it. When Harry came he asked me what the issue was in which I told him and then he performed a diagnostic on my furnace. Long story short he tested my carbon monoxide and the actual unit and told me everything is fine. He did suggest if I really wanted to I can replace that specific part if it bothers me but he recommended that i just let the furnace run its course and them replace the entire thing down the road. Harry was fantastic. He was really trying to help me save a few $$$$ and not try to sell me something which I appreciated. I will be going back down the road for any heater/AC needs

Positive: Professionalism, Punctuality, Quality, Responsiveness, Value I recently used High Efficiency cooling and heating to install a new furnace, tankless water heater, and A/C unit. Karnik is very knowledgeable and explained everything. He also took care of all the paperwork for the Government rebates. He was always in contact and kept me in the loop when the installers were coming. I would recommend Karnik and plan to work with him again on another project. Services: Install AC, Thermostat installation, Heating system installation

I was desperately looking for a qualified, trustworthy and knowledgeable person to assist me with an issue I was having with my condo Havc. I had made a few calls and research in advance. After a warm welcome from my call to High Efficiency Cooling & Heating inc. i was connected with Serguie. Sergiue arrived and was exactly what I needed. My condo unit is tenanted so it was extremely important I had someone who would be sensitive and understanding to them and acted quickly and efficiently, Serguei did just that. He successfully repaired a leak at had that ended up saving my a lot of money! He stayed committed to address every issue and concern I had. I had to address further issues with my condo and Serguei walked me through that. I don’t review often, but when I have an A++++experience I feel it’s important. Hands down the best Havc technician out there. I highly recommend this company.

Positive: Professionalism, Punctuality, Quality, Responsiveness, Value Prompt service, very knowledgeable! Took the time to diagnose and fix when another company was ready to replace without doing due diligence. Really happy with the communication, turn around time, and advice for what to expect and look out for!

Positive: Professionalism, Punctuality, Quality, Responsiveness, Value I had the pleasure to speak with the technician as well as Charton. Both were extremely professional and helpful. I reached out to Charton during an emergency situation and he came home within an hour. There was no sales pressure from him but at the same he was very transparent about the whole process and very pleasant to deal with. I got a really competitive pricing from them. I recommended this company to my friends and even they have been really happy with the service. Overall I am happy that I have identified a reliable company. Service: Install heating system

We got our AC, furnace, and central humidifier from this company. The people here are very professional and know their products very well. They have completed a thorough assessment of what we needed for our home and we have been very happy with the professionalism and work they have done. When they schedule an appointment, they are on time (which is very important to us). I would totally recommend to my friends and family. Charton was amazing and he helped with everything that we needed. He goes above and beyond.

Pirabaharan was very competent and knowledgeable. He asked about the problem, inspected the cleaner components and got inside to look at the chassis components and then fixed the problem. He also responded to my questions about the furnace and checked out my concerns. Very satisfied

I called this company to fix the AC problem last December, and the technician clearly identified the problem and made the replacement of the necessary part only. This week I had furnace not blowing hot air. I called the company and the same technician came. Again, he went through the system and didn’t have to replace any parts, and the furnace returned to normal operation. I appreciated the knowledge and the honesty of the technician.
