"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."

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."

"Joe, the AirCo sales representative, was very professional. He actually asked for my feedback on priorities for a new boiler. This was important to me because the boiler sits below our family room, and the noise level of the boiler was as issue. His proposals listed several boiler options, based on heating efficiency, which were competitively priced. The installation was run by Steve, who was able to fit in the installation the next week. Steve, and his crews, were punctual and courteous, and the installation went smoothly.

Heating and Air Conditioning questions, answered by experts

The $5,000 rule for HVAC systems helps homeowners decide whether to repair or replace an AC or furnace. Take the quote for the HVAC repair cost and multiply that by the age of the HVAC system. If the total is higher than $5,000, it’s more cost-effective to replace the system. If the total is lower than $5,000, consider repairing the system.

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.

Yes, unfortunately, scorpions do come up through air vents on occasion if they’re not properly sealed. These pests are excellent at finding small openings and may use vents as a pathway to cooler areas inside, especially during hot weather. To prevent this, inspect your vents, seal any gaps, and install fine mesh screens where necessary.

While spending money once or twice a year to tuneup your AC and furnace might seem like a waste of money, think again. The cost of HVAC maintenance is far less than the cost of replacing your furnace or AC unit, regardless of the type of HVAC system you have. Paying this smaller fee now will help you avoid paying much more significant costs in the future. Not to mention, having a serviced AC and heating system will help keep your home comfortable, no matter the season.
