We had new AC/Heating (Split) system installed. No more lugging up & down AC's every yr. The crew - professional, prompt, patient with our questions & concerns. I appreciated their kindness toward my husband's cookies & very dry humor. Looking forward to Simmons returning to install heating driveway. Thank you for job well done Service: Installation

I have used Simmons plumbing for a few years now, no matter how big or small the issue is at my home they always come right out and repair the problem. They are extremely polite and respectful in my home and the wonderful ladies in the office are just simply the best! Service: Plumbing pipe repair

We replaced our furnace in our Salisbury Beach Condo Unit. There was a total teamwork of players at Simmons that made the installation project perfect. The team of Craig, Nick & Marvin (?) (hope I got his name correct), did a great job. They had to cut out and remove the old furnace then install the new one. They did a very clean and efficient job.

Many thanks to those behind the scenes from the initial proposal to procuring the new furnace to scheduling, etc. I highly recommend Simmons Plumbing & HVAC with any of those needs for your home. Thank you - Charlie

Be very careful with this company. They are more readily available than others and make their very-high labor rates known upfront. What you don't know is the exorbitant fees they charge for parts. Expansion Tank: Over $150 charged which can be purchased for under $40 at Lowes; a more than 3x markup. Water feeder valve: Over $200 charged which can be purchased for $80 at Lowes.

That's for the entire unit where they only replaced the top half of the unit, not the entire valve. I have no issue with them replacing just the top half, but don't charge 2.5x the cost of the entire valve. Relief valve: Over $150 charged which can be purchased at Lowes for $35; a more than 4x markup. Their crew seemed proficient, but the parts (and labor) prices are extremely high.

We had a plugged kitchen drain - I called Simmons. They sent two techs to our house within a few hours. It was a tough job, but they did an excellent job. The techs were very polite, knowledgeable and made recommendations for alternatives. They left the area very clean. Thank you Service: Plumbing pipe repair

Simmons Plumbing team competitively quoted and installed a replacement high efficiency gas boiler and dual unit ductless AC system at my house in early January 2021. The installers were punctual, organized, effieicnt and did quality work. It was a big project done with minimal interuption to my home working schedule and lots of care for the property. One month on, the systems are working very well. I'm pleased with all aspects of the Simmons team process. I'm happy to have chosen Simmons for this work.

Wanted to say how pleased I am with Simmons. My wife and I started to have a puddle of water in our basement which over time became more like a lake. Once I contacted Simmons, they sent a crew out first thing next morning and fixed the problem very quickly and efficiently. I didn't meet the crew as I'm in bed recovering from a broken leg, however my wife said the 2 young men were very polite and explained exactly what had happened. The fee was very reasonable. I would certainly recommend Simmons unreservedly for a/c work and can assurme they are as good with boiler

Had Simmons come out for a water heater issue and later for a leak under our sink. We ended up having them replace our sink, faucet and garbage disposal. They were great with communication, as I had to email a few times to ask questions about sinks. We were very pleased with both jobs that they did.

My wife and I woke up Saturday morning with no hot water. we left a message with Simmons plumbing to see if they could come by and within minutes I got a call back! The gentleman was very polite and patient and was able to walk me through fixing my problem! He even called back the next day to see if we were still ok! I highly recommend using them again! They are very friendly, very fast and he didn't even charge me for his time on the phone. Jeremy F Merrimac, Ma

Simmons saved the day. and my frozen pipes! It's never a good thing to discover that you have no water due to frozen pipes at 11:00 at night. And it's really not a good thing when your "regular" plumber doesn't return your emergency call. I searched online and got recommendations from friends and called Simmons Plumbing located not far from my home on Railroad Avenue in Seabrook.

I had to leave a message because I am not a regular customer, but they returned my call first thing the next morning. I explained my situation and they told me they would have someone come to my house within the hour. They arrived about 15 minutes later! Dave and his helper went to work right away with a large heater and managed to thaw out the frozen blockage quickly, with no damage to the pipes.

They discovered that it was my water meter that froze. It has a break plate that is designed to crack if the meter freezes so they told me it would have to be replaced. We had to coordinate a visit by the town water department to replace the damaged meter. Fortunately, they were not far away and were able to stop by with a new water meter within an hour. Dave and his helper left to help another customer with frozen pipes while the water department was here.

Once the water department was finished, Dave and his helper returned to finish up their part of the job. They also replaced my old heat tape and re-wrapped the entire water meter and the pipes coming from the ground with new insulation. What a nice neat job they did! They were knowledgeable, hard-working and super friendly. They managed to turn a most stressful situation into a very satisfactory experience.

And amazingly, I was able to be at work at 1:00 PM so not much lost time, either! I was not a regular customer when I called Simmons, but I told them they can consider me a regular customer now! Thank you for the great job!

My water heater let go and flooded my basement. I called Simmons Plumbing and they had a truck there right away. My water heater was replaced immediately and my venting was repaired. They were quick, clean and professional. I highly recommend them.

Furnace died on one of the coldest days of the year. My previous plumber had retired. Simmons came to the rescue. Dave was on time, courteous and fixed the furnace quickly. Even offered suggestions on how to clean and maintain the furnace. Price was reasonable and Simmons has gained a permanent customer!

During one of the coldest spells I had mistakenly wired a humidifier to my furnace and lost heat for the night. Spent hours debugging different parts of the heating system. The tech at Simmons was so incredibly helpful and despite being busy with regular customers guided me (over the phone) through the diagnosis. I had some basic electrical knowledge but really the help was incredible. I wanted to post a review to let others know and that I am definitely going to be calling Simmons back to install my humidifier once i warm up

Everyone at Simmons was very helpful in diagnosing and repairing our furnace. Response time was prompt, office personnel and technicians were polite and knowledgeable, and we were very happy with our end result. We have also used Simmons for service and repairs to our air conditioning system and sump pumps and always been pleased with their response times and service.

We have used Simmons on many occasions. They have diagnosed, repaired and serviced our furnace, air conditioning system and sump pumps. Always a quick response time with courteous and knowledgeable staff. Very pleased with their work and customer service. Will use them again and again for our service and repairs.

We have a very elaborate beachfront property. We're very used to contractors going high on their estimates. A minor emergency requires me to find a local HVAC/Plumber quickly. They came at the specified time. The work was above and beyond what I expected and the bill was less than half what I expected.needless to say I will never call another company for our climate and plumbing needs.

Make that 6 different tags, plus the stickers. I found two more hanging from other pipes in the basement. They must have really bought them in bulk LOL!

Since I purchased my condo in 2014, I have been experiencing problems with my boiler not maintaining the temperature set on the thermostat, when we would experience a prolonged cold snap with temperatures below 20F outside. I tried making adjustments such as changing the thermostat or turning the heat up beyond my normal house temp in an effort to "ride out" cold temperatures, but the indoor temperature, even if set as high as 75F would still drop ever so slowly to 60F and sometimes 58F.

No upward adjustment of the thermostat would remedy the situation. When these issues would occur, the temperatures outside would be very low, causing the service reps to make emergency calls for issues such as leaks from frozen pipes, so by the time a service rep could make a house call for me, the outside temperatures would have rose above 20F and the boiler would seem to be operating correctly.

It wasn't until I got the service repair man Craig (last name unknown) that my luck turned around. Instead of dismissing my concerns or my historical knowledge of the situation he listened and continued to troubleshoot the system. After trying several things he opened up the front panel and noticed that the aquastat temperature dial had been turned down to 140 F.

I have a Boiler with forced hot water for my heat. These systems should be set at about 180 F, and typically they are left at 180F and no further adjustments are made. We hypothesized that the previous owner had turned the aquastat down in and effort to save money when the condo was on the market. Craig made the adjustment and replaced a reducer valve as well.

My system was not originally set up properly as there is no air scoop, so the system must be purged of air at least on an annual basis or the air buildup in the lines will lower the efficiency of the system. Craig took the time to show me how to bleed the lines properly, waiting patiently while I took notes. He also explained how my system worked, the limitations, and what could be done to improve the system.

I was left feeling much more knowledge about my boiler and had the confidence to do minor troubleshooting. Unfortunately, we weren't out of he woods yet. The pressure release valve blew hours after the aquastat had been turned up. I called Simmons emergency line and the gentleman on the phone was able to talk me through what to do. The success of that call was mostly due to the knowledge I had gained from the service call with Craig.

I was able to turn the aquastat down and bleed the lines to reduce the pressure. Simmons sent Craig back out the next day where he replaced the reducer valve which was under warranty, and installed a larger expansion tank. Ever since that day my heat has been working properly. The expansion tank I had previously was not sized to fit the system and it was installed upside down. Craig corrected those issues explaining each step along the way.

I have Simmons clean and service my unit ever year and will continue to do so thanks to the excellent service I received this year from Craig. On my own I insulated all the hot water piping that was visible in the closet where the boiler was and in the attic, as well as installing heat trapping curtains on the bedroom windows. Each day we now turn down the thermostat when we leave the house to reduce the energy consumption.

This was not possible before the repairs as the heat, if cold enough outside, would not rebound if left too low. With the changes that Craig made along with the additional insulation my heating bill went down by $30-40 as compared to the same month in prior years! I am a satisfied customer and want to give full credit to the excellent service Craig provided.

I have just installed a new furnace with Simmons. They provided many options when quoting and were on time for installation. They worked diligently to correct an electrical issue with my old thermostat, and when they had to schedule again for the next day they apologized for the inconvenience. The technician worked through the issue successfully. The work was completed neatly and successfully as quoted. The techs were polite and tried to be as unobtrusive as possible. I am very happy with Simmons!

Look elsewhere for a plumber. Let me preface this by saying that we should have looked at Yelp first. had we seen the one star rating, we would have kept looking for someone to replace the filter. We have come to respect Yelp! Ratings. 1st issue: We had a leaking sediment filter and purchased a brand new housing and called Simmons to install it. While installing, The young man melted the new housing and then charged us to buy a new one! (He admitted to us he was new and was afraid he'd lose his job, true or not we bought the story and paid for it! SHAME ON US) 2nd issue: we decide to replace the sediment filter with a carbon/sediment filter and learn that we didn't get the correct tool to unscrew the filter housing (2nd new housing the plumber put in was different from the one he melted.) So we call to get the tool, at 3:30 on a Friday. Gal says that she will find out what we need and get back to me.

At 4:30 I call her back.she hasn't been able to get in touch with the technician to find out what filter he used. she tells me she won't be able to get back to me until Monday and to have a nice weekend. Really? ( this is laughable.would he really have my file from three months ago with him in his truck? Wouldn't you think it's filed away in the office?) 3rd issue: The receptionist just left me hanging. I had to call her back.amazing. UPDATE: we never heard back from Simmons Plumbing. No call Monday, Tuesday, Wednesday.nothing. Poor Customer Service

We were in a difficult situation; our 10 year old heating/hot water system failed and found out it couldn't be repaired and needed to be replaced. We were recommended Simmons Heating Plumbing and gave them a call. Within 3 hours they were at my house going thru the options that I had available. John spent over an hour with me going over my concerns and explaining the components of the new system I was looking to purchase.

We decided to go with Simmons Heating Plumbing and within 3 days we had our new system installed. My wife and I were delighted with the crew that installed the system. It was obvious that they were well trained, skilled and professional. Any questions my wife or I had they were happy to answer and provided a complete explanation. The install itself is so nice, its well organized and neat! We had an unplanned and very frustrating situation and Simmons Plumbing was able to correct our situation by providing excellent customer service!

My wife and I got a quote for a furnace on a house we ended up not purchasing, but working with John from Simmons was great - He provided a great quote and price for the job. Now that we purchased a new home, we needed a plumber to hook up our gas dryer and connect our water line to the fridge. I called Simmons based on the good experience I had with them in the past, and Chris came the next day.

He was very friendly and did great work. I will admit the job was pricey, but the quality of the work and Chris' personable and helpful nature makes it totally worth it. Lastly, I knew Chris was a good guy when our exploring cat "trapped himself" in the bathroom behind the washer/dryer being installed - Chris picked up the cat and handed him to me with a smile, not the least bit bothered - It's that type of small stuff that will have me calling Simmons anytime I need a plumber. Many thanks!
