We called when our A/C broke during a heat wave over a holiday week, so obviously knew we would be in for a substantial wait, totally understandable. They told us they would call back in two days. When they didn't, we called back and he said he would call us right back in 15 minutes. He didn't. I just don't understand why he didn't tell us off the bat that he didn't have time for us, or wasn't able to take new customers at this time. We luckily booked with another provider who was able to actually schedule an appointment even though it was a week away.

After 2 other plumbers my sisters' called within the past week, to try to figure out, during this extreme cold snap, why the heat in my 84 year old mother's house was not registering above 59 degrees for a week (we bought in space heaters to keep her warm), I went onto Angie's List and found Gassco Inc. Last night, I left a message via Angie's List for Gassco asking if they could help resolve the problem. They responded first thing the next (this) morning (by 7:45am). I talked to them and they said they could send someone out, even in the midst of a cold snap, with MANY people without heat or with other frigid-temp plumbing problems. They called me, as they said they would, when their technician was on the way. The technician arrived right on schedule. He came in, diagnosed and SOLVED the problem right away, within an hour, and charged a reasonable fee for his service. My elderly mother's heat is now on and she is very happy, as am I, that she is no longer cold.

On December 1 we our furnace was not working. Gassco was called and they came out that evening for an after hours call. The young man was courteous but wrong in his diagnosis, not even close. He was able to start the furnace but indicated that major repairs would be needed to fix the issue for the long-term and the issue could not be resolved that evening because of the need for specialty parts, etc.. Thirty minutes after he left, the furnace stopped working and since we believed that there was nothing that we could do that evening we waited until the next morning. The next morning I contacted another company who sent someone out that day. That person looked at it for five minutes and said that it was minor thing. Ten minutes later, he fixed it and did not want payment because it was such minor issue. He further said that the previous technician was incorrect in his assessment and should have known better. I contacted Gassco that day to tell them what happened. The person that I spoke to said that sometimes this can happen. The technician and the person I spoke to the next day were polite but I was disappointed that the offer of even a partial refund was not offered given that they obviously did not do an adequate job and completely misdiagnosed the issue. It has been one month and no issues at all with the furnace.

I am a landlord and have asked my tenants to contact Gassco from time to time with various HVAC issues. Every time I hear good things, communication is sound, replies are quick. I am not local and managing these properties from abroad. The trust is important and I look forward to a long term relationship with Gassco.

Overall very positive experience even though it took a little while to diagnose and get to the root cause (well actually I cannot say this because they were right with their first try but then inadvertently installed a faulty part to fix it). They decided to try the part again after a bit more troubleshooting and fixed it. Very reasonable cost.

There was some minor plumbing work that needed to be done. I called and spoke with Jim from Gassco Inc. I called them around 4:50 pm on November 18, 2015. Wednesday. I spoke with, I believe the owner, Jim. I explained that my toilet wasn?t working. He asked if I could send him pictures of the toilet. I did and never heard back from him. I wouldn?t recommend him because he never bothered to respond. His e-mail was gasscoinc@hotmail.com. I don't have a note, but I believe I also had told him that I would want more work done as the bathroom actually needs to be renovated. I knew that the work I was asking to have done wasn't a big job, but had looked up plumbers on Angie's list and that is why I contacted him. I also knew I was calling late in the work day, and apologized for that. Even if he had told me that he was way too busy, I may not have been happy about that but would have preferred that response to just being ignored.
Description of Work: I called this provider. He asked me to e-mail photos of the toilet that needed repair. After sending the pictures, I never heard back from him.

This job took several trips and some trial and error, including one emergency visit when something didn't work and the heat went out altogether. But in the end Gassco managed to fix the problems I've had for quite a while which were caused by another clueless plumber. They put the time into trying to figure out my system and how to get the job done right, and didn't gouge me on the cost. Nice people.

It was one of the coldest weekends of the year. We were very grateful. Years later, when we went to sell our home, we didn't like the way the system venting they installed knocked against our door when we opened it. We called GASSCO, and they responded taking full responsibility for correcting the situation, and repositioned the pvc so that ran properly, and beyond that, helped me in the process to correct the drainage of that and the nearby water heater to flow directly down into the drain, rather than how originally installed to just drain out over the drain hole. I cannot tell you how grateful I was to have such consideration and over and above responsiveness. Thank you GASSCO. Thank you Bill.
Description of Work: Gassco helped us out by installing a new furnace when ours stopped working on a long weekend, when my husband, son and I were all home sick, and then came back years later to fix an issue pertaining to the install.

Everything seems to be working as it should, given all circumstances (age of system, scope of work, etc.) We've used them once before and like the idea of using the same company as long as we're satisfied, which we are.
Description of Work: Called after hours for a service call. Got a call back within minutes. Service schedule for 10a two days later. They called that morning and asked if they could come early. They could and did. Unit was serviced. Tech showed me the gory details and tested the system before accepting payment.

I called to make an appointment for a tune up on our central air system and was given a time of 3-4pm on 5/29/14. The tech called me at 2:15pm and asked if he could come then, but I had no one to meet him until 3pm so he waited. My partner arrived to let him in, he did the tune up, and left out the back door without telling anyone he was leaving. I was not in the house, so I called him to ask if it went OK. He said the system was getting old (it was installed 8 years ago - doesn't seem old to me) and I should replace a bunch of parts soon but it was OK for the season. A few days later I received a bill for $169.95. I felt this was a lot of money for a seasonal tune up - my mistake for not asking what the price would be. I felt they were reasonable in the past when I've used them. I called to express my concerns for such a high bill for what seemed like little work, and I was told I could take off $25 as if I had one of their coupons.

In two emergencies, they were here in a flash and got me up and running without delay and with a fair price. Annually, they ahve taken care of routine maintenance, are fairly priced, always professional, delightful to have in my home, respectful of my property, etc. I highly recommend all of the Gassco employees. The only thing preventing me from updating my 30+ year old a/c system is that I won't need Gassco.

Response from Gassco Inc.
We are sorry that we did not return the call sooner. Our company policy is to take care of existing customers first. This was a very, very busy time for us because many homeowners were trying to get heating equipment installed before the really cold weather came, and also make some deadlines for rebates. I wish we had called her back to tell her we so busy. Sorry.

I was very hopeful about using GASSCO to help with an oil burner issue in my home. They got great reviews on this site and are located very close to my home. About 24 hours after leaving a message on their answering machine (during business hours), I got a call back from one of their service reps. We scheduled a time for him to come out the next day and he arrive right at the appointed time. He look over by furnace systems and I was impressed by his quick diagnosis of the issues. He promised he'd get right back to me with an estimate. After a week I texted him to see when I could expect something from him. He said it was almost ready. A week later, still nothing. I text again asking if they we still interested in doing the job. Again, he promised he'd have something to me right away. Another week goes by and nothing... As a small business owner myself, I understand about supply and demand. Sometimes you just don't have the capacity to get to all the work. All I ask for in that case is the straight story. It saves a lot of time and aggregation on both ends!

Response from Gassco Inc.
We and our techs got out of servicing oil fired equipment for all new customers some time ago. We had been turning the calls over to a trusted friend who was still working in oil. Because this customer had such a bad response, we now simply tell callers that we do not service or install oil equipment anymore. Sorry we could not help.

Very professional and affable. Same day service on first visit. Appeared to be very thorough. Not cheap, but that may be the market price. First visit came and checked AC for malfunction, found it working property but low in coolant and refilled. Then tested temperature coming out of vents inside. Second visit was to check and fix a coolant leak. Spent several hours onsite and appeared to do a great job since the AC has been working great after their visit. The coolant leak test/fix was $500 which seems a bit pricey, but I know labor is expensive. All the technicians were pleasant and seemed very knowledgeable. I had a terrible experience with a prior AC/HVAC repairman and this was like night and day.

We needed a new gas furnace before our very old one died. We called 3 companies for bids, including Gassco, which we have called twice before for an annual service on the old furnace (which was always a good experience). Gassco let us know several options,and also about the MassSave program and encouraged us to check into that for rebates and financing if available. They also advised us about an upcoming EPA deadline after which the lower efficiency furnace were considering would not be okay to install (which we then read about in the Angie's List magazine). We talked with several guys at Gassco at various times, and each person seemed knowledgeable and part of a well connected team. From the fist visit to give a proposal, to the day before installation to confirm measurements, to the day of installation, the Gassco crew was on time and worked efficiently. There was one follow-up visit to take care of the filter access door, which had been overlooked, but that visit also went well. All very nice guys, and reasonable. It's never easy to have to spend money on things like this, but this experience seemed as painless as possible.

Argh! One of the hottest days of the year- and a saturday- and our central a/c 's condensor burned out*. They were out within 45 minutes and the a/c was back on in less than 20. This is a man who LOVES his job. How often do you get THAT experience?Prior to this call- they were also out in the spring to do the spring maintenance on the unit.Someday, we'll need to replace this old unit, but we want to keep her working for as long as we can- Gassco was all about helping us do just that- even though they could have TRIED to sell us a new system. * Note to self- don't turn an a/c on and off repeatedly to get the unit to turn on at just the right degree setting (I have since replaced the old thermostat with a new digital one and all's well. Lesson learned.

During a winter prep for our gas furnace Gassco staff indicated that our furnace and duct work was not to code. After discussion with them and informing ourselves about the situation Gassco removed the unit and prepared to install the new one. Their staff discovered asbestos in the ducts, left by the previous company. Through their contacts we were able to very quickly have the asbestos removed. They completed the work within the time allotted and we are enjoying our new system. Their staff is knowledgeable, respectful, friendly and competent. We are so pleased to have found them.
