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."

"Topic is a home water supply Shallow Well which operates with a shallow well jet pump + pressure tank installed in the basement. I had been collecting parts over the summer, as I knew the original to house jet pump would go out soon some day and with covid parts are hard to get quick, so started collecting ahead of time. Glad I did as the pump started leaking, from the housing. Replacement needed. Not an emergency but time to get it replaced. Was a ticking clock as it also looked like the pump was twisting putting stress on piping as original owner did not mount it and other fittings had large amounts of corrosion on them. I supplied these parts for the job: new 1hp jet pump, 44 Gal. pressure tank with T package, water filter housing, brass fittings, brass check valve, brass ball valves, 1" copper pipe and some copper fitting, and 2x10 pressure treated board to mount the pump/board to the floor with concrete anchors. Called up Sila on 10/14, master plumber Dave was available on 10/16 to come quote the job of installing what I supplied and misc. parts still needed. Talked with me and received my requests for specific design wants and he supplied his opinions & additional ideas and other options like wall mounting of water filter, sensor shutoff option and different water filter all together and we worked out the plan, did not do the different filter or sensor though. Talked about brass pipe and fittings at the pump up to the pressure tank and we agreed what I had purchased was good and would last a lifetime, vs copper all the way which would still last a long time. Quoted $2800 with water filter bypassing and $2600 without the water filter bypassing. Job was scheduled for 10/22. Quote was high level line item as listed here. Came a bit late on 10/14, due to an emergency call, no big deal Dave called to let me know. Was on time for installation on 10/22, 7:30am. Two workers on Job (Dave + 1, sorry I’m horrible with names +1 was an electrician and was helping Dave) Job took ~ 8 hours to finish. What was not able to be completed: Was not able to replace old original check valve. Well started to suck air when old was started to be removed, confirming there is no foot valve on the line or a broken one, so old check valve was kept. Concern was not being able to recover from air going down the well pipe causing priming issues. At this point the job would require a well expert and was not able to be replaced by Sila. What part of job was mis-understood: Mounting of jet pump to board/floor. Ended up missing the concrete anchors to start and installing after the fact with a different method. Made it more difficult to mount the pump and did scratch the rust proof paint. But it got done. Nice and sturdy. What was complicated on the job: Something that should have not been an issue at all went wrong. I had purchased 1” brass unions. There were two unions installed. One was found to be causing leaks during the initial job installation. This caused extra rework during the initial job. After job completion and area dried with a fan, it was found that both unions were leaking. The original one that had issues in the initial job and the 2nd one. One is pre pump and one is post pump. Called Sila office on 10/23 and told them what was happening, Dave’s earliest availability to come back was was 10/26. He was on time on 10/26. Dave stated that 1 union was giving trouble and replaced it with one spare that I had also purchased. When looking at the 2nd union again he was not able to get it to seal and he made the call and changed the design to direct copper connection and no union, I did not object as at this point just wanted the job done. No More leaks on that location, but also no ability to easily break the connection for future maintenance. When left no leaks. However, after using water for a while the 1st union started leaking again. Texted Dave direct with a picture and said he could return on 10/28 and I requested him to bring a union from his supply. Arrived when he could with ~ 1hr notice and replaced the union with one of his. When looking closer at the issue unions that I had purchased it was found they were cracking. Summary: I’m a novice in pluming, reason for calling Sila. I wish Dave would have noticed the poor part / crack issue and replaced unions from his stock on day 1. I was trying to save time by collecting parts over time and ended up causing issues. Dave knew he was working with brass and seems like he did not have backup stock on site incase of issues. Wish he did as I’d have two unions… and he would not have had to come back twice to repair the leaks. The call was made to not use the brass ball valves I purchased so it was clear that my parts were recommended to use but not absolute. Overall Dave and team did a great job, it’s clean, organized, valves and drain spickets installed nice and logically, filter is at good height, job completed like I asked and planned with Dave, except for the above jet pump mounting, union issue and check valve replacement discussion above here. Dave and team was professional and focused to get the job done. Thanks Dave for your hard work. Reason for Rating: I am giving this job an A rating based on the end result, Sila stood by the workmanship and resolved the issues that arose. That is a sign of a great company. If I would not have supplied the couplers that issue would not have happened ultimately and the check valve & well priming issue was just out of reach and would have required a well specialist to complete. The pump mounting was probably just lost in the large amount of details we had discussed, again it is mounted sturdy."

"David did a great job clearing out clogged drains on mini splits and servicing all 7 units and 2 condensers. The amount of time he spent and thoroughness was clearly a step above the prior maintenance. Now we know what really needs to be done to keep the units working well, and recommend Forest Hills HVAC for any mini split system. Only drawback was that we got bumped a few times for emergency calls. We were not an emergency because we did have some functional units, so it is fair that we had to wait. If it was an emergency, I could have paid the emergency fee and gotten work done more quickly."

"Installed two heavy window air conditioners, lugging them up from garage under to first floor. Appt was scheduled for 9:30 am, called them at 10:15 and unfortunately the owner had had a very bad night with his mother in hospice care. Finally came at 11:20. They were willing to wear masks inside our house. Installation went very quickly and smoothly. They knocked $25 off their usual minimum hourly rate because of the delay. Very friendly, would definitely hire them again (and probably will for A/C removal in the Fall). Would have been 5 stars except for the arrival delay."

Heating and Air Conditioning questions, answered by experts

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.

A new air conditioner capacitor will cost less than replacing the entire air conditioner system. While a capacitor itself will cost between $8 and $25, paying a professional to replace an AC capacitor will cost $180 on average. It’s not safe to replace an air conditioner capacitor on your own. 

Yes, you can run an attic fan with the AC on. In fact, you don’t have a choice with a passive attic fan. Plus, when an attic fan draws out hot air from the attic, it helps regulate the temperature of your whole home, so your AC doesn't have to work as hard.

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.
