Shawn is the most professional serviceman I've had. My dryer vent needed cleaning and he took before and after pics to show me and explained the process and gave tips on how to prevent such build up. It was raining out and he wore booties in the house that I really appreciate. Nice young man - he will be successful in all he does.

I didn't actually get the service because of the cost and the hard upsell from Mike, who was nice, but too aggressive. I have cleaned the dryer duct many times and was just looking for a break due to some ill health and because two years had passed since I had done it. I spent more time talking to him than it took me to do the job myself after he left including pulling the back off the dryer and vacuuming it out, including ensuring the heating element wasn't dirty (which they don't do, per their site they just vacuum out the lint trap).

He quoted $99 for the first four feet then $10/foot after. For the ~20 feet that came to $400 which is just ridiculous for the provided service...running a rotating brush down a duct and only vacuuming out the lint trap. He was pushing hard that my UL listed flexible foil duct that is less than half the 10' was going to burn my house down (it's been in place for a dozen years at least) and quoted $1400 to add 8' of galvanized 4" duct. I agreed that it was an improvement that I had planned but I told him would be less than $100 and take me maybe fifteen minutes to install (I priced it out afterwards. It was $45 for two 4' x 4" lengths and $15 for a 45-degree elbow). A good rule of thumb is that anytime a job is more than 3X the parts you should question the quote and this came in at 30X! Really? And he wanted a $1000 deposit! NEVER pay a deposit for an essentially labor only job. NEVER.

Cleaning was double what was suggested when I googled it and all the pressure was more stress than it was worth. I don't know whether there was some sort of creative upcharge because he came out on a snowy Sunday? In any case, I can't recommend Delta. I have flipped houses and managed projects for decades. I refused to do business with him and he kept pushing all the way out the door. I can't imagine recommending Delta to a neophyte or the elderly. Just awful.

Although I initially had friction working with Delta Clean Air, their management worked to rectify the situation at a pace and with a candor that I simply didn’t expect.

The quality of the work they did was good, availability of appointments was great, and their follow up to resolve the issue after seeing my review is rare. I will work with them again in the future.

This company is a total scam; stay far away! I had hired them to come out and clean our vents ahead of the winter season. The technician came out, walked around the house, and quoted me on the spot - it seemed expensive (well over $1K), but I was in the middle of work meetings and just said to go with it. However, unlike what Massachusetts law requires, the technician never actually had me view or sign the quote ahead of time. (Actually, when I called to book the appointment, the woman who answered said that they do the work same-day - further proving they don't send quotes ahead of work being completed, regardless of price). After the technician left and I had time to digest the breakdown of costs (which he sent after the fact), I asked for more information on the antimicrobial solution used, and I asked for photos of before and after pictures of my vents and the HVAC entry they claimed they did for further cleaning. None of that was provided, aside from a few bogus screenshots of random dirty vents (that were not mine). Finally, the technician and I had talked on-site about not needing to clean the return vents, but the receipt thereafter showed he did a "deep clean" of all of them. When I called the company phone number (on their website) to ask for a refund, it was only the technician who called me back to tell me "I forgot" everything we had talked about. This company does not deserve your business.

Delta Clean Air was the greatest investment I’ve made so far, very professional in their work, they put your satisfaction first and the price was very affordable.

They did a good job with the dryer vent cleaning. This was an easy first-floor job. They charged $300 for a 20-minute job, added $14 to pay with credit card, and then asked for a tip on top of it. You can get better value elsewhere.

It seems they contract out the jobs to others. You probably need to negotiate with the guy who shows up or state your price when you schedule the appointment.

Very quick to diagnose and fast to repair. Highly recommend. came next day at 8am and were done in few hours. oil company told me it will take 2 weeks and more than a day to repair

Alborz was referred to me from a friend. HVAC was down. I called. They came out the next day. Diagnosed the problem. Ordered a part. Came back and fixed unit. Good and reliable. I would recommend.

We've used Alborz Corp to maintain our home's gas furnace for 5 years and are very satisfied. Sam and his team respond quickly, and their workmanship is excellent. We recently had them install a new furnace & smart thermostat -- the furnace installation is rock solid, and they took the time to guide us through installing and using the thermostat phone app. And their pricing is very fair -- strongly recommend!

Incredibly customer service oriented, my AC stopped working and the team came same-day taking advantage of being close by on another job! He had all equipment ready and fixed in an hour while also explaining maintenance as a first time home owner!

Great service- speedy and thorough. Sam was able to accommodate me while servicing my neighbor's AC unit. He fit me in, repaired my AC unit when Silas told me it was dead. So glad an angel was sent to save the day. I would recommend this company to anyone needing HVAC service
