• My A/C stopped working on one of the hottest days of the season. Mehrdad was very quick to provide recommendation for new A/C and furnace, reasonable quote and came within a couple of days to get the work done. They were very professional and did the work within a day. I’d definitely recommend them! Thank you Mehrdad!

  Jasmina S.★★★★★

• I had HVAC Boss install a new Lennox air conditioner, and I couldn't be happier with the experience. From the initial quote to the final installation, the team was professional, knowledgeable, and punctual. They took the time to explain everything, completed the installation efficiently, and left the work area spotless. The new Lennox system is running perfectly and has made a huge difference in keeping our home comfortable. If you're looking for honest, reliable, and high-quality HVAC service, I highly recommend HVAC Boss. Excellent work from start to finish!

  sepehr T.★★★★★

• I couldn't recommend Mehrdad more! He has worked on several properties for us over the years, and every experience has been exceptional. He's incredibly responsive and easy to schedule with, and when both of our A/C units failed within days of each other during a heatwave, he went above and beyond. He managed to fit us in for an emergency appointment, sourced two new units, and had everything installed within just two days. Mehrdad and his team were efficient, professional, tidy, and an absolute pleasure to have in our home. Their workmanship and customer service are truly top-notch. If you're looking for someone you can trust for HVAC service, repairs, or installations, look no further. And don't forget to book your twice-yearly A/C maintenance—it's well worth it and can help prevent unexpected breakdowns. The best of the best. Highly recommend!

  Sara★★★★★

• Honestly Merdad saved us! Our AC gave up on us earlier today, and within a few hours ON A SUNDAY Merdad came, diagnosed the issue and had it repaired in under 30 minutes. It was 29 degrees in our house and I have never been more grateful!!!! Highly recommend!!

  Joanna C.★★★★★

• I had an excellent experience with Mehdrad! He was extremely thorough when diagnosing the issue with my air conditioner and took the time to explain everything in detail, making sure I understood my options. I was especially impressed that he was able to arrange for a brand-new A/C unit and have it installed the very next day. This happened during a heat wave, so I felt incredibly fortunate to have my home cooled again so quickly. Mehdrad was professional, knowledgeable, efficient, and truly cared about providing great service. I highly recommend him to anyone looking for reliable HVAC service. Thank you again for wonderful service!

  nadeem S.★★★★★

• Excellent service from Merdad. Very professional and thorough. Explained all of the nuances of what caused my problem, and was very transparent in costs depending on what the root cause of the issue was.

  Jimmy★★★★★

• ⭐⭐⭐⭐⭐ I had an excellent experience with Mehrdad as a professional HVAC installer. Mehrdad and his assistant did a really great job converting my hot water tank into a tankless hot water unit. The whole process was smooth, efficient, and done with great attention to detail. They were both very professional, polite, and respectful throughout the entire job. They took the time to explain everything clearly and made sure everything was working perfectly before they left. The quality of their work really shows, and I couldn’t be happier with the results. I highly recommend Mehrdad to anyone looking for reliable and skilled HVAC services!

  Omid S.★★★★★

• Very knowledgeable, well priced and efficient installs!

  Sajna M.★★★★★

• Our experience with Merhdad & his team was excellent from start to finish. The team is professional, and very knowledgeable. They explain the installation process clearly, answered all our questions patiently, and made sure everything was completed safely and efficiently. Strongly recommended! The installation was neat and well-organized, and they left the work area spotless afterward. Our new furnace works perfectly — the house heats up quickly, runs quietly, and is much more energy efficient than our old system. What impressed us most was the team’s honesty, attention to detail, and commitment to customer satisfaction. We truly appreciate their hard work and would highly recommend their furnace installation service to anyone looking for reliable and high-quality HVAC work.

  sophia H.★★★★★

• Can’t recommend HVAC BOSS enough. I’ve worked with him for 2 projects now - one large multi residential and one single family home. The former was a brand new install and the latter was a retrofit split ac addition. For both projects, he exceeded my expectations. Reliable. Trustworthy. Incredible attention to detail and quality of work. I’ve worked with 2 large HVAC companys in the past, before working with HVAC BOSS, and so I know how that not all experiences are as positive as the ones I had with HVAC BOSS. Highly recommend.

  Ben C.★★★★★

• We contacted so many contractors to find the best unit, best service, and best price. HVAC BOSS and Mr. Mehrdad were the only ones who delivered on all three. We got a full back package from them — a new Lennox furnace and AC — at the most competitive price I found. It was actually the lowest quote I received, without sacrificing quality. What really stood out was the process. This wasn’t a simple job because our home is older and we needed new ductwork added. Mr. Mehrdad and the team visited 2-3 times before we even confirmed the order. They did full inspections, calculated the right capacity, and explained every detail. Every visit made me more confident they were the right team. After 2-3 months of planning, they completed the install perfectly. Professional, clean, and no surprises. We’re extremely happy with the results. Highly recommend HVAC BOSS if you want a team that actually cares about doing the job right.

  Matt S.★★★★★

• Mr. Mehrdad delivered top-notch service from start to finish. They installed our AC professionally and left the place spotless when they were done. The whole process was smooth, very professional, and their prices were competitive too. Highly recommend them to anyone looking for quality HVAC work. Great job to the whole team!

  Lee A.★★★★★

• Thank you so much for answering my questions regarding the HVAC trade, I really appreciate it!

  MD R.★★★★★

• Merahad was excellent to work with. Very reliable and fair with his pricing. I would definitely recommend him and his team to everyone.

  yianni D.★★★★★

• Great service, reasonable prices!

  SEAN P.★★★★★

• I recently had HVAC BOSS install a new furnace for me as part of an oil-to-gas conversion, and I couldn’t be happier with the entire experience. From start to finish, their team was professional, knowledgeable, and efficient. They took the time to clearly explain the whole process, answered all my questions, and made sure everything was done safely and up to code. The installation was clean, well-organized, and completed on time with great attention to detail. The new system is running perfectly, and the difference in efficiency and performance is already noticeable. It’s clear they take pride in their work and truly care about customer satisfaction. I highly recommend HVAC BOSS team to anyone looking for reliable and high-quality HVAC services.
