Lowe's Air Duct Cleaning is an honest and reputable company, specializing in air duct cleaning business. We always stand behind the jobs we do and guarantee the best quality results for each project. Additional phone numbers - (800) 699-0955, (781) 205-2474 & (978) 965-3474.

"After Lowe's came to clean the dyer vents at my condo building, my dryer was no longer venting. I contacted them and initially they said they would send someone to check the vent. They then called back and said my vent was never clean because it was disconnected and they could not help me. This was strange because the dryer was working fine before they came. Also, in my trash there was foil tape that you would wrap around the vent. This made me think that they did try to clean the vent despite saying they did nothing. I contacted my management company who said there were never any previous issues with my vent. I called Lowe's back and told them this and they still insisted that they never touched it but would check with the technician. I looked into it my self and found that in the section of the vent between the dryer and the ceiling there was a mass of lint the size of a small animal (see the picture). It was so large that moisture from the dryer had also built up and flooded the bottom of the vent hose. The building manager was then able to clear another mass of lint from the section of the vent in the ceiling and the dryer then started venting to the outside. It was never disconnected like Lowe's said. It seems they started cleaning it and just jammed the dust all the way back to the dryer. Why they didn't finish removing it is a mystery. If they ever service my building again, I will refuse."

"My chest freezer broke down and I did not want to buy a new one since I could not afford the same size. I reached out to appliance parts pro and they were confident that what I ordered would fix my problem. $200 in parts later and I now have a broken freezer on my porch and am still paying the loan to this terrible company. They just want you to order parts and try them because they know you can't return them. I hate this company with every fiber of my being and will make sure that anyone that has a broken appliance will not use them. To top it off, their site is so screwed up that it give you an error trying to log back in. I ended up having to create THREE different accounts because every time I went to place a new order, it would not let me login and it would not send a password reset email. DON'T GET RIPPED OFF."

WE INSTALL BOILERS. And we do it well! Commercial & Residential services available for: Plumbing, Heating & Gasfitting, BOILERS, Radiant Heating, Water Heaters, Solar Heating, Kitchens & Bathrooms. We've been providing these services for a VERY LONG TIME and would love to provide our expertise and attention to detail with your next project. Give us a call today! P.S. I always return emails

"Ray quoted a replacement natural gas steam boiler at a price well under what both Boston Standard and Sila quoted me. Well under meaning close to 20% less. Ray is very responsive by phone and he shows up when he says is going to. Ray had done maintenance on our old boiler prior to this complete replacement. He actually performed maintenance on our old steam boiler, unlike when Boston Standard and Sila did maintenance they would simply turn it on and made sure it fired up. When Ray came and did maintenance after the 4 years we had both Boston Standard and Sila maintain our boiler he disassembled and cleaned out the incoming piping, replaced the glass water tube level, added a skimming drain, skimmed the boiler, etc. The prior 2 companies never did that level of work and it was in bad shape. In addition, not many technicians have knowledge of steam boilers these days even though they are still quite common in New England homes. Back to the new replacement boiler that we just had completed. Ray did a fantastic job on the installation. I really couldn't ask for better service. He was timely and efficient (we had our heat back on the same day), explained everything thoroughly (usually multiple times for my benefit) and has called and come back to check on everything a couple times since the installation. He's really gone above and beyond. We have 1-pipe steam radiators and he understands the intricacy of steam quite well. Ray also did all the plumbing when we had our kitchen renovated. He was our contractor's choice for a plumber (which is how we found Ray) which gave him that extra credibility knowing other professionals use his services. I would not hesitate to use Ray again in the future and recommend him to everyone."

Heating Oil questions, answered by experts

Your HVAC manufacturer will give you instructions on how often you should service your system. Have your unit professionally serviced at least once a year when in doubt. 

Heat pump systems are different because they provide heating and cooling solutions for your home. In this case, you should have it serviced at least twice a year.

Yes, including optimizing settings and suggesting upgrades if needed.

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

Costs depend on system age, type, labor, and whether part replacements are necessary.

The homeowners guide to home care is here

From average costs to expert advice, get all the answers you need to get your job done.
