Commercial HVAC Clinton

When our air conditioner went out this summer with a house full of guests, a friend referred us to Trademark Tek. The dispatcher was very friendly, understood our urgent need, and she was able to get us scheduled for same day service. Justin arrived on time, was very knowledgeable, and had our a/c back up and running much more quickly than I expected, and without breaking the bank! I highly recommend them!

Thank you for fixing our AC today! Both cars and our home were without AC so we had no refuge! You were prompt, courteous and priced right! Even the co that installed our unit on our home wouldn't get back to us! Thank you!

~ Amanda O.

I was actually this wonderful companies first customer. Let me just say, if you want quick service, complete professionalism and top notch prices, this is the best place. It was over 100 degrees for like 2 weeks straight, and I have a 7.5 month old, then he was 6 months. I called in the afternoon and our AC was repaired by 7pm. The best part, it was completely affordable. I am very grateful for this company and highly recommend their quality service.

Greater Boston Heating & Air Saved Us! When our heating system went down at 3:00 in the morning, they were here within minutes to get us back up and running. Fair prices, friendly HVAC technicians. You can't go wrong. Highly-recommend!

Bill from Akian Plumbing was extremely professional, friendly, responsive, and service oriented. He arrived on time in a mask, gloves, and booties. He immediately diagnosed the issue with our toilet, carried out the repair quickly and expertly for a reasonable price, and then checked in on any other issues we might have while he was there. We couldn’t have been happier with Bill’s amazing service and will certainly turn to Akian again in the future for our plumbing needs.

~ Pat Lee

Professional and quick service. I found all the staff to be very helpful and friendly. Appreciated that they were easy to get ahold of and gave me an accurate window of when they would arrive. Followed covid precautions and social distancing well. The staff was very knowledgeable and answered all my questions and made great suggestions for general and quick maintenance that would save me money in the long run. Also found their quotes to be competitive.

~ Mara H.

It was easy to book and I was able to get an appointment quickly. Bill showed up on time and was professional, clearly experienced, did immaculate work and also installed an additional piece that will save me on future maintenance. Cost was totally reasonable and will be using Akian as my plumber going forward.

~ William Stearns

Used them for three projects, one of which was an emergency job. Each time they responded very promptly and professionally. Their work is top notch and I would recommend them in a heart beat.

~ Greg

Akian Plumbing was friendly, efficient, and affordable. I appreciated that they were very straightforward with their pricing and also offered excellent customer service. They replaced my water heater and did an excellent job (they also charged hundreds of dollars less than all the other companies I quoted ahead of time). I absolutely plan to hire them again in the future!

~ Karin

I’ve used Steve and his team across several properties (each with their own nuances), and they do phenomenal work. They are prompt, efficient, flexible, fair, and perhaps most importantly, transparent. They will illustrate what happened, how it happened, provide mitigation strategies, and things to avoid in general.

~ Justin

Metal Masters has taken care of our family for over 22 years and never let us down. Responsive, knowledgable and friendly. Always helpful. I have learned a lot from the various team members to improve our home air quality and reduce our costs. Great team.

I have been doing business with United Service for the past 25 years and have always had a positive experience. They are always responsive and professional and whether the job at hand is small or large, I know I can count on United Service to be there. They go above and beyond to ensure my needs are met, something you don’t always find. I would highly recommend United Service to anyone looking for reliability combined with the highest level of professionalism and customer service!

United Service is an outstanding family owned company, we here at Finz Seafood and Grill and Sea Level Oyster Bar have been using them for 15 plus years. Ron, Nic and Alexi and their team have been great to work with, to calling in issues and getting right out to fix the problems and finding parts quickly.

~ Serie Keezer | Finz Seafood and Grill, Sea Level Oyster Bar

We called United Service Company when our ice machine stopped working on a Friday morning. Our hall was booked for the weekend and buying ice was not an option. The technician, Nate, was there within a couple of hours and had us making ice again and FAST. United Service Co was fast, professional, and courteous. We will DEFINITELY use them again in the future!

~ JF | Lowell, MA

This has been the second large walk-in purchase from United. Both purchases were installed on time and on schedule. United also services our coolers and responds quickly to last minute service calls. I truly enjoy the relationship with United Service.

~ Chris Bandereck | Topsfield Bakeshop Inc., The Whoopie Wagon

Great service! Always available 24/7 for emergencies. Definitely would recommend, they’re worth it.

~ Agave Mexican Bis

I just have to express how wonderful this company is. They are contracted with my property management. My AC went out this past weekend on the extreme heat. They scheduled me the earliest they could, and were very friendly. They were on time and able to quickly fix the problem. I am so grateful for their quick response. I would recommend them to anyone.

~ Rebecca Barney

National Heating and Air is a top notch business! The estimator Rick was thorough and gave me several options, no pressure and really listened to my needs! The installers Dustin, Greg and Tim we so efficient, polite, respectful and did a great job. They left my house neat and tidy with only minor disruption. They were great to work with! My new system works great, quiet and very even heat throughout the house!

~ Gracia Goodriich

I have been a customer of National Heating and Air Conditioning for several years. One of their technicians, Jeff, has done most of my routine maintenance and is always professional, very knowledgeable, personable and usually arrives early! He recently installed a new motor in my Heat pump and did a great job. This was during a period of 100 degree weather. He identified the trouble, ordered the motor, and arranged delivery during the time he was working on the unit the next day. I had not expected to find relief from the heat so quickly. Thanks, Jeff! This is a honest company with qualified technicians. You can count on them to do their best for you.

~ Gran Sweets

From beginning to end this company did an amazing job! They are very professional, yet so kind and friendly. Even let us borrow heaters to help keep our house warm until we could get the new heating system installed. Use excellent products and everyone from repairer, estimator, office staff and the installers were all awesome. Really appreciated when they came to the house they always wore masks without being asked. A huge bonus! I would not hesitate to recommend them.

~ Beverly

I have had National Heating and Air Conditioning technicians out to my home in Ashland, OR twice this summer. First to do an initial inspection and service on my air conditioner. A couple of months later my HVAC fan motor needed replacement. Both times they responded promptly and they were knowledgeable. Each time they understood what I wanted and took care of it quickly. I found their charges for parts & services quite affordable. I am happy to depend on their services again for any of my HVAC needs in the future. I can recommend them highly!

~ PC

The company was efficiently and courteously represented. The installation was well-done.

~ Louis D.

The team at Cooling Unlimited is just that: a team that is well coordinated, solid to work with and highly efficient. 'Can't say enough positive about the firm and it's staff.

~ Ann N.

Wonderful service. From start to finish service was prompt, courteous and thorough.

~ Jane K.

The folks at Cooling Unlimited were great! They always returned our calls/emails immediately and answered all our questions. They were quick and neat and did a wonderful job.

~ Cristina F.

Excellent service. Competitive pricing. This is the second time I've hired Cooling Unlimited for an installation and each time the work has been done right, efficiently and with attention to detail. Highly recommended.

~ Mike R.

Fabulous! Call no one else! Competent professionals with good advice and excellent follow through. On time, tidy installations. Very happy customer.

~ Marta B.

Excellent service. Excellent work for installation of Mitsubishi ductless system, including financing, support for obtaining rebates, and price.

~ Ovidiu A.

Great company. From the office staff to the installers; everyone was prompt, professional, and easy to deal with. I'm very satisfied with my new AC system. I'd recommend Cooling Unlimited to anyone looking for heating or air conditioning work.

~ Chris B.

Excellent service at a great price. Cooling Unlimited as one of three companies I considered for the ductless AC install at my home in Cambrige. I chose them based on price as well as the high degree of skill and thoroughness of their sales technician.

~ Steven H.

Very professional. Their expertise was exceptional, they installed a balanced system in a preexisting summer home that looks like it was installed when the house was constructed. Great Guys!
