G & S Heating installed our furance in 2010 since then we have had them inspect yearly our furnace and no problems ever with it.  They have kept our furnace in good repair and we have had no problems until the thermostat quit working.
We bought one and installed it.  It ws very complicated and we had to call for help from the company who made the thermostat.  We got a foreigner and could not understand them.  we did get the thermostat to work but not efficiently. 
We had it for less than a year and it quit working so we called for emergency to G& S Heating.  They came immediately checked the furnace to be sure it was working properly and then found that it ws definitely the thermostat.  They recommended one of their thermostat that was much simpler to work and we had that installed that day. 
We had heat immediately and were warm and comfortable due to their quick response to us.

The whole experience was great - Willie was my repairman and he was prompt, courteous, and explained the problem and what he had to do to fix it - the repairs took two service calls but I was only charged for one service call - Willie expedited the second call as he knew I was without heat - I will not hesitate to use G&S Heating the next time I have a problem

The technician arrived on time and was professional and courteous. He answered all my questions and did his work quickly and efficiently.  I asked for additional service to be done and he was able to provide it without an additional service call.  
Great experience. We will use them again in the future.

We were very pleased with the service we received from G&S Heating and Cooling.  When we needed to replace part of our heating unit we decided to go with a complete new product since all other parts had been installed at the same time and are likely to fail soon.  We are happy with our new heat pump and with the ease of installation.  The folks at G&S are wonderful to work with.  They are very competent at their jobs and I highly recommend this company for any heating, cooling, and electrical work.

Overall I was very happy with their service.  There was a little issue with appointment time,( some communication issues between scheduler and service people but after that all got worked out it went great.  The gentlemen were very helpful with teaching us about our heater, we thought there was something wrong but we had changed the thermostat setting without realizing it  :)
This was the 3rd time we have had them out to service our house ( we have only owned it for a few yrs). The previous owners had used them and were very happy with them also. They have always been very professional.  I highly recommend them.
Was also introduced to their Pre-paid Program,  which for our family works out well.

We had such a great experience the first time we used them that we decided to sign up for a pre-paid annual service where they check everything periodically to make sure it is ok.  For both the furnace and the thermostat, they did a beautiful job, and they even gave us a discount for signing up with their prepaid service.  They are very pleasant and always right on time every time they come.  I would recommend them to anyone.

I want to write a review for GS Heating, Cooling & Electric Inc in Monroe, Washington. They are GREAT!!!!
In the past year we?ve needed a heating company to come out to our home twice. First, due to a fire in the electric box of our 2nd floor furnace & most recently for a no heat in one section of our home.
With the first event the fire in our furnace electrical box, the fire started around 330 am, thank goodness we were able to get the fire out on our own before it possibly burned down our home.
Since we run a B&B out of our home & it was November we needed our furnace to work. We called GS Heating in Monroe & they sent out a guy right away to assess our problem. Although they couldn?t fix it that day due to the fire damage they got us on their schedule right away & had us back up & running within a few days. Lots of sheetrock removal & electrical work repair needed.
Now almost a year later we had another problem with the same furnace (we have separate furnaces on each floor). It?s late in the day & this time with B&B guests to arrive within hours, I discovered that no heat was coming out of vents in the guest?s room. My immediate thought was oh no its 40* outside I need heat in this room! So I called GS Heating, the pleasant lady on the other end of the phone did all she could to fit me in as soon as possible. GS heating arrived the next morning & began to assess the problem. The technician (Keith) began troubleshooting & found nothing wrong with the furnace, it was running properly. This then began a seek & find mission to see why NO air/heat was coming from the vent. The technician began to figure out where all of the duct work for our 2nd floor was at but without being able to find the ductwork for the end of our home that is past our 2nd floor bridge. That told him it must be in the crawlspace, so down into the crawlspace he went & sure enough he found all the ductwork for that end of our house no longer attached to the floor joist but laying on the ground. He then picked up a portion the ductwork only to find it full of water. Now to figure out where the water came from.
The technician was able to figure that out it was from our heat pump coolant coil overflow which was blocked by years of dust most likely & the water had nowhere else to go but into the duct work. With this discovery, he knew that the GS ductwork crew would need to come out to fix it so he called the dispatch & set them up to come out the next morning. The tech then made sure that the overflow was cleaned out & he showed me how to clean it each year going forward, which no one had told us we?d need to do in our newly built home that we?ve lived in for 7yrs.
The next morning another very nice guy GS technician (Carlos) showed up to fix our ductwork. He took all the precautions I appreciated to make sure he didn?t make a mess of our home & he had our ductwork replaced & heat pouring into the guest room within a short time.
I would recommend GS Heating, Cooling & Electric Inc in Monroe, Washington, to everyone who wants a company that cares about their customer?s needs & who do all they can to get you fixed quickly.  Call GS Heating, Cooling & Electric Inc in Monroe, Washington today if you have a need for their services.  They care about their customers needs.

Each and every time I have had work done or maintenance done by G & S Heating, they have responded quickly, working around my schedule, which I appreciate.  I think they now know that I only have Friday's open, as I work Sunday through Thursday.  And they are very cooperative.  After the work is done the office always calls me to make sure everything was done to my satisfaction.  That is great customer service.  I recommend G & S Heating to anyone in the Puget Sound area.

They did the job start to finish including  the geothermal system,electrical work and grading.
All the employees involved were very professional and careful in doing their job. 
The system is very quiet and has greatly reduced our power bill over the years.
We have had G&S doing maintenance on the system ever since and it has run trouble free all this time.
We would recommend G&S to anyone who needs to have work done in their home.

It was wonderful. We love G&S! We decided to use them again because we were so pleased with the previous work they did for us. We remembered that they don't just do heating and cooling, but also do all kinds of electrical projects. We figured that we already had a great relationship with G&S, so why not use them again? We will continue to call them anytime we have any heating, cooling, or electrical needs.

GS Heating AC Electric was referred to me by a friend that had used them several times before. I needed to several circuits to my
computer office at my home. I also wanted them to wire in a generator box. Their estimate was quick and precise. I am always apprehensive at getting work done because I am always waiting for the other shoe to drop and have more charges added to my bill.
Not here, they say what they do and did what they said. They talked me thru the entire job so that I would be completely happy with their work.
The work GS performed was pretty straight forward and their serviceman went straight to work after our talk. He installed the circuits and electrical lines neatly and cleanly.
I am very pleased with how they left their work area and very happy with the quality of their work.
They even called days later asking how things were working and if I had any questions. Very Impressed!

This review has been long overdue to a company that is well deserving of accolades. We worked with G & S to install our Geothermal
Heating System and Emergency Backup Generator. After spending our first winter in our new home with Propane Heat, we discovered that spending close to a $1,000.00 a month in propane was not a sustainable expense for us. After doing some research on Geothermal Heating systems, we settled on WaterFurnance as the unit we wanted. As luck would have it, G & S was the company that sold, serviced and installed WaterFurnace. Roger was able to line up financing for us and we started the installation  process.Installing a Geothermal system requires a significant effort and we were fortunate that G & S chose to document this installation to create a video detailing the process that is now posted on their website. At the end the process, G &S left us with a system that has saved us thousands of dollars a year and less than a 48 month return on our investment. The first December in our new 3700 sqft home, I received a propane bill for $1100.00 for the propane forced air heating system. The following December, after G & S installed our Geothermal System, with the thermostat set at a constant 76 degrees,our heating bill for the month of December totaled $127.00. When we've needed service or any adjustments, G & S has been there for us with a level of service that has been unsurpassed by any vendor we've dealt with over the past few years. We were so happy with the work that G & S did with our  Geothermal System that we purchased a Emergency Backup Generator. The Kohler system that G & S recommended has performed beyond our expectations. We had a long list of requirements regarding which appliances and rooms that we wanted the back up generator to to service in the event of a power failure and it was a challenge for G & S to design this system. However, they not only met our expectations, they have exceeded them in every way possible with this system. Their electricians are as talented as they come and the electrical inspector who came out to do the inspection confirmed this.Anyone who is considering hiring a Heating and Air Conditioning or Electrical contractor would be wise to hire G & S for their project. Each and every contact we've had with G & S has been an absolute pleasure. The quality of their customer service is something that is lost with most companies today. My only
complaint is that they don't have more products that we can buy from them. I can't say enough good about this company.

The quoted price was about $2,400 and the estimating experience was great. They were professional and it took two or three days to get the written estimate, which was a little longer than I thought it should be. They did not get the estimate to me when they told me they would. I would use them again if their prices are competitive.

Roger and each of the workers he sent out, as well as the outside contractors he used to dig the trenches, are all smart, professional, exceptionally courteous people. We had zero complaints and were in fact astonished by several on-beyond-expectations moments: one occurred during the final walk through when Roger opened the door to a small bathroom in the back of the house. He pointed out that we had failed to plan for a vent and ducting for that space. Mind you, we had not considered adding this room to the system as it was an orphan addition to the house that had not been integrated into the previous system either. The next day the new vent and additional 9 feet of ducting was installed, AT NO EXTRA CHARGE! He couldn't bear to see an imperfect system--even though we had not expected or asked for that particular detail. (I can't count the number of times we have each commented on how glad we are that the room now has heat and air conditioning. That bathroom is now the primary bathroom in the house!)

Another exceptional moment included the extra work the company did to reroute the wiring of the entire house to a new panel. The previous panel had been located improperly above a toilet in the same homeowner-renovated back bathroom mentioned earlier. I feel much safer with the new panel tucked under our eaves. I also appreciated Rogers's suggestion that we add a plug-in for the generator we plan to buy so that we have light, heat, and refrigeration should the power go out.

Finally, in addition to the exceptional quality of the company's work, I have to say that the best part of the experience was that it was all rendered exciting and fun. We quickly realized our pocketbook was being respected which meant we could simply enjoy watching our new system take shape. Our kids were treated with good humor too--even brought on over to be shown how each part of the project was being created. They are on first name basis with Roger as well as two of the guys who were here every day for a while.

I can't praise G&E enough. Every one of the employees we had contact with feels privileged to work for Roger, who clearly feels great respect for them as well. This is definitely a company I would recommend to my dearest friend.

     G&S has always been price competetive. The final bill has never exceeded the initial estimate.  Their staff is very courteous, friendly and very professional.   They are always on time, and when they show up, they work steady to get the job done as fast as possible, while still doing an excellent job.   The technition always takes the time to insure I understand the work that was done, as well as the detailed billing.  They always do an excellent job of cleaning up before they leave. 
   When the circumstances require it, they have always worked well in cordinating work and job functions with other contractors on the job site.          Other companies that I have used in the past, have sent out inexperienced personel to do the maintenance that were little more than "filter changers".   The maintenance technitions at G&S are very experienced and extremely knowlegable, with up to date training on the equipment they service.   They do a very thorough  job of checking everything to insure are components are in proper working order before they leave.
    I am very confident in recomending G&S Heating.  No matter how big or small a project, they have always done an excellent job!
