Our electrical system is wonky in our bedroom.  We asked G&S Heating to help us out.  Two guys showed up and kind of fixed the problem.  When they left we noticed that they burned out a brand new timer switch for a fan we had installed in another bathroom. We had no way of turning off that bathroom fan.  So it stayed on until we could get them to come back to the house.  They came out a few days later to resolve the issue and put in a temporary switch until we could buy a new one to replace the nice one we  had installed.  We scheduled the appointment for Thursday (Christmas Eve) as that was their earliest appointment.  No one showed up.  I tried contacting the office and they were gone for the holidays. Basically, we waited around for nothing.  The person who scheduled the appointment did apologize and offered to have the guy come out today but with such a bad taste in my mouth I don't want them in our house.  We spent good money and I feel like we got poor service and even poorer quality of work.

Inspection went very well.  Gary was very informative and provide candid feedback.  Based on the inspection I scheduled several follow up appointments for additional work.  Cost was on the higher end, but overall the work is great!

Great. I was awakened at 2:30 in the morning with he detecters sounding off LOUDLY, again many times. We had replaced many of them 10 months ago. The loud warnings (along with EVACUATE! EVACUATE!) were horrible and my pets had a rough time, as did I. 
After taking the alarms down, I thought they wouldn't go off again, but they did. I called G&S at 1:30 Friday afternoon and SOMEHOW, Gary and his crew came after finishing a job earlier than expected. Thank goodness. He was very professional, sympathetic and got to work quickly. He found the wiring in a couple of the alarms was wrong, had to replace two faulty ones, reset the electrical box, showing me which ones would shut them up in case they ever went off again. 
I really appreciated their quick response, knowledge of their task and caring they didn't leave a mess behind.  Thanks guys! I will certainly recommend them again.
Oh yes, I got a $30 Angies List discount!

G&S was my second ductless system bid. My townhouse neighbors use the roll around portable A/C units to cool isolated sections of their homes but I wanted a system that did it all. Initial consult with Jesse was thorough and professional. Follow up scheduling, payment planning and customer care by Dawn was equally professional and accommodating. Workers got here promptly on appointed day. Immediately assessed the workload and called backup. They got it all done between 8:30 and 4:30 which even amazed them. I had one refrigerant leak after 3 weeks. Technician was out here during 4-hour scheduled window and repaired leak. All is well and I'm freezing happily ever after.

We called Saturday when our hot water heater went out. A nice, professional technician came out promptly, said he thought he could fix it but had to make sure he could find a part. He said he'd be in touch Monday and gave us his cell number.
Monday morning we texted for an update, "Any news?" Got a text back, "Not yet." 
Tuesday morning we texted for an update. No answer.
Wednesday morning we texted for an update. No answer. At noon I called the company to find out what was going on. A nice young woman sent me to someone's voicemail, saying that she was "out on a job" but would get back to us promptly. Wednesday evening, and nobody has gotten back to us. 
Now we have to pay another company to come out and do the diagnostic before we can get it fixed, so $230 down the drain. And I haven't had anything but cold showers since Saturday.


Update: It's now Friday evening, and we've heard absolutely nothing.

GS Heating replaced my furnace with a Lennox energy efficient system.  With the exception of the install techs not showing up when they were supposed to, the work was done well and went off without a hitch. 

Additionally, I had a cracked cooling pan in my a/c unit which the installation tech (Ryan) inspected to let me know if I would need to replace the entire a/c or just the cooling pan.  He found out that they would be able to obtain a cooling pan from the manufacturer to replace just the pan and that I wouldn't need to replace the entire a/c unit.  He decided at the time to calk the two areas where the unit was leaking in the garage and asked me to wait until summer time to see if that fixed the issue or not.  Summer is here and I noticed that his solution didn't work so I called the office to have them come out to replace the cooling pan.  At this point, the office manager/receptionist (Diane) indicated that Ryan had not put anything into their system as a note and that she would have to charge me for a tech to come out to do an evaluation.  I told her what Ryan had shared with me but she said, "Well, there are no notes in the system, so we have to charge you to do an assessment of the system."  What's unfortunate is that I had a great experience with them for the installation of the furnace but now I feel like they don't care that I'm a potential repeat customer.  She told me that since I opted to not have the a/c fixed in the winter (which Ryan told me to wait until summer to see if the calking of the leak might fix the issue) I have to pay for another tech to come out an confirm what Ryan told me they could do - replace the cooling pan. 

She went on to say that since it's summer they've got a lot of people who need/want installs and essentially the gist of what I was getting from her was, "we don't really need to do anything to win your business again". I guess when it's winter time, I'd get better customer service for the a/c than now in the summer????  I'm disappointed to say the least. I don't want to pay what I consider a redundant fee for what has already been diagnosed needs to be done. The owner, who I spoke with back in November was the main reason I went with GS Heating because he was upfront and seemed truly interested in winning my business.

I called Diane back and asked her to have the owner call me to see if he's able to resolve this situation.  Since the install tech didn't put notes in their system about my a/c issue back in November, I feel I'm having to pay for someone to come out and re-diagnose what he found in November.  My rational for giving GS Heating a C on Professionalism and indicating that I wouldn't use them in the future is due to a lack of follow through and attention to detail by the tech in entering notes into their system about the potential business they could have in replacing my cooling pan.

He was able to confirm some of my issues with outdated electrical wiring and the need for a panel upgrade.  He checked all outlets to determine if they were grounded and took a visual look around.  I did expect a bit more of an in depth inspection and a more detailed report. However, I should have taken the time to ask details on what a whole house inspection would involve.  Overall, the inspector was nice, punctual, and knowledgeable. He provided a quote for the upgrading the panel in a timely fashion.

We got quotes from 3 different service providers and although they were similar in price, G &S explained more about the different types of furnaces available and seemed more knowledgeable than the other two providers.  They were very professional, arrived on time, and completed the job in less time than was originally estimated.  The owner also came back a week or two later to check on the system to make sure it was operating properly.  This is the second time we have used them, the first time was for electrical work and we will most definitely use them again.

First, we called the company about our old furnace, that was doing a weird noise. The attendant told me that the visit would cost $85.
Then they sent the diagnostic expert to see what was going on. After around 2,5 hours of service, the specialist said that we needed to replace the furnace, as the 28 years old one was condemned.
At the end of the visit, they charged $85 for the visit + $(*) for every 15min of service. *I don't remember exactly how much was every 15 min, but the total was around $450. I was not told about the extra cost for every 15 min of service. They have a deal was that if you replace the furnace with G & S, they won't charge you for the diagnostic. 
In a first moment, I didn't want to continue the service by G & S, as I didn't like the surprise of having to pay 5 times the price I was told. I cancelled the next visit and was already looking for another company to have the job done. However, this got to the knowledge of the owner Roger Thompson, who promptely called us to understand what was going on. His attention with the case made us changed our mind. He investigated, and admitted the there was a mistake from their side. He offered to charge us only the $85 that I was told. 
After seeing his care about the case and honesty, we decided to give them a second chance. And We're happy we did it.
Than the schedule a visit of a salesperson, who presented to us all our options.
After we decided which one we wanted, things happened really fast: on Monday they sent a guy to take the measures (sorry, i don't know how this profession is called). On Wednesday, the guys came early and and got the job done. At night, my house was warm and nice again.
On the week that followed, they sent the same salesperson again, for a quality follow up. Everything was perfect. Very nice job. Trustful company.
