"I have been using duct kings to clean my dryer vent for several years. They always arrive on time and thoroughly clean out the dryer vent. I used them again this year and they provided the same great service! It was great to have the same technician who was familiar with my home to provide the service several years in a row."

For emergency services, please call 781-933-6387. N.E.T.R., Inc. is here to help homeowners install the best heating and cooling systems that fits their needs. Since 1989, we’ve installed heating and cooling systems in Boston and its surrounding areas, tackling tough problems that our clients face. Our goal is to ensure our clients have energy efficient, quiet, reliable systems so they can live their lives to the fullest both at home and at work. Our dedication to our customers’ needs is what drives us each and every day. Our approach to temperature control and comfort has helped us become one of the most respected names in heating, cooling, and refrigeration in New England

"Before installing a mini-split, the sales person told me that I'd need to cut down an interior shelf to a specific height. I paid a handyman $400 to do exactly what the sales person instructed. Later on, N.E.T.R. came and did the installation; however, AFTER the installation, a technician told me that they hadn't accounted for the vent opening and closing and that the shelf would need to be further cut down. As you can imagine, this type of service is rather ridiculous. If they knew that the shelf would need further cutting, they should have NOT installed the unit. I have called N.E.T.R. six (6) times in three weeks, and no one has called me back about this issue. After paying for the unit and for a handyman, it's ridiculous that I have AC that is compromised because no one with the company thought to properly measure the space so that the work by the handyman could be done once. At this point, I'd like for N.E.T.R. to take care of this for me."

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."

Heating and Air Conditioning questions, answered by experts

Most HVAC surge protectors last about three to five years, depending on how often your home experiences blackouts or brownouts. If your unit is susceptible to more frequent electrical surges, consider replacing your surge protector every two years. Consult your HVAC professional to determine when and how often to replace your HVAC surge protectors.

It's recommended to change HVAC air filters every one to three months. The frequency depends on factors such as filter type, indoor air quality, and whether there are pets or people with allergies in the household. Regular filter changes maintain proper airflow, improve indoor air quality, and ensure efficient HVAC system operation.

If an air conditioner is younger than 10 years, it’s worth trying to repair it in most cases. Some basic maintenance or a cleaning might bring it back to working condition. However, many HVAC pros swear by the “5,000 rule.” If the estimated cost of your repair multiplied by the unit’s age is more than $5,000, it’s time to replace it.

Evaporator coils in HVAC systems typically last around 10 to 15 years. However, their life span can be longer or shorter based on factors like the frequency of your HVAC system usage, whether regular maintenance is performed, and environmental conditions. Regular maintenance, such as HVAC system cleaning and coil inspection, can extend the durability and efficiency of your evaporator coil.

HVAC maintenance is crucial for the longevity of your unit. Without proper care, your HVAC unit can break down frequently. In addition, a system that is dirty and not cleaned correctly will not heat or cool as efficiently and will increase your energy bills due to the increase in energy consumption. Additionally, you will probably have to replace your unit sooner than you would if it were properly maintained, which will cost you more money.
