    Excellent. The work was completed on time and to our satisfaction. The following month (which was colder than all previous months), our utility bill decreased by approx. $125. That was a very pleasant outcome. The sales personnel and installers were courteous and professional. I would recommend them to friends.

    This company and it's "family" {staff} are awesome. They go above and beyond to attain exceptional full service with a genuine caring attitude. While the cost may be somewhat higher {not at all bad either all things considered} you can be assured that it is still "the best bang for the buck" because you get quality products, absolutely no hassles, excellent thorough service from the office and the workers, and just in case of problems they are there for you Johnny on the spot....no questions asked, no hemming and hawing, no excuses. Absolutely friendly professionals. They are respectful as well. I'm telling you that you will find NO BETTER.Just so you know, this review is freely given with no compensation whatsoever. In fact, I will be forthright about this. I paid not one red cent to have all the work Halco put into my home. Why? I was referred/ selected by Empower New York to have this work done as I'm disabled and on an extremely limited income. The work and products that Halco put forth were exactly what any paying customer would have received. Now that's what I call work ethics AND morals. I am so grateful to them and Empower New York for making sure that I have what I needed despite being poor.

    By Susan P.

    Halco performs annual maintenance on our boiler and split ductless ac - both of which they installed several years ago. Although their price was somewhat higher than others, they offer a 10 year "bumper to bumper" warranty. We actually benefited from that when the boiler had issues and was out of the manufacturers warranty. What would have cost us over a thousand $ in parts and labor was at no charge. They are punctual, professional and clean up after themselves.

    Customer Review

    By Joan K.
    Ithaca, NY

    Halco is absolutely amazing! We pay $12 for plumbing and $15 a month for heating and at the end of the year you get 2 free hours of any labor you need and they will go around and do what ever needs to be fixed at that time. They are very A typical people so they want to come in and they want to do a good job and to teach you. I had a lot of electrical work done by them and when the New York state Inspector came in he looked at the electrician and said this man is excellent and I've never seen any problems with his work he is wonderful. Everything was up to code and done perfect A through Z. They did a job that normally would take a week to do in 3 days because they stayed so long every day to make sure the work got finished. They are always very prompt to arrive and always on time and if they can't make it they notify you in plenty of time. We had a plumbing emergency come up in the middle of the night. There was no water. I called at 12 AM and they had a plumber to my house by 4 AM and had the problem fixed. I can't say enough good things about this company. They are excellent and I've always been so happy with them. I would recommend them to everyone .

    Customer Review

    By Casondra C.
    Cortland, NY

    Spray foam basement walls and rim joist, install new high efficiency furnace, air seal and blow approx. 12" cellulose in attic, install new kitchen door, install 18 new windows with aluminum trim.  Starting with the energy audit, Matt performed a blower door test and gave some recommendations for how to make our old brick house more energy efficient. Throughout the process, Matt was professional and knowledgeable with his recommendations. The work was split into three separate groups that came to our house, [1] the insulation and air sealing crew, [2] the furnace crew, and [3] the window crew.  The two guys that came and did the insulation arrived on time, were very friendly, and did an excellent job with the work. Knowing that house house was especially leaky, they were meticulous in the attic, being sure to seal every possible source of air infiltration.  The next group that came were the furnace crew. Again, they arrived on time and were very professional with the installation of our furnace.  Where I was really blown away with Halco though was their window crew. We had previously had three windows replaced with another company, and were hesitant to have Halco do our windows as we knew their reputation as an energy company, but hadn't heard much about them doing windows. I couldn't be happier with our choice to use them. They offer Sunrise windows, which have an excellent R-Value for the price. Every day, Larry and the window crew arrived on time and were some of the most professional people we have had to work on our house. Taking a few extra days because of the difficulty of the trim work, Larry made sure to take his time on every single window until they were perfect. He even was able to reinstall a 120 year old stained glass window we had in our barn in a way that would preserve the window and keep the house energy efficient.  Overall, I really couldn't be happier with our decision to use Halco. Their customer service is absolutely excellent and they offer service at a top-level quality.

    By Hector S.

    I called them to help my diagnose and fix my furnace because the previous owners had maintenance plan with them. They came out and I was not satisfied with how things went however they have a 100% satisfaction guarantee which I was not aware of and so the residential manager came out the second time with another tech and they made sure everything need was done correctly. I will say that I am happy to learn that they will stand by they guarantee of 100% satisfaction and will do business with them in the future. The work to fix my furnace was not a big job and they completed the work at no charge to me and refund me my initial payment event though I insisted that I paid for the service they performed.

    We had work on our home almost 2 years ago. This February being as bad as it was, we had terrible ice dam issues that went beyond what we should have had considering we spent a small fortune and had all our walks, crawl spaces and roof insulated.(blown in) HALCO came immediately and saw damage, took pictures and corrected areas of concern. I would not hesitate to recommend them based on response. A bad experience turned out good.

    We have used them for years- they come out and perform maintenance on our air conditioner. We pay a monthly fee for maintenance. They are really good- they put the air conditioning in when we replaced it about three years ago. We got a really great unit- it is better than the one we had before and the price was right and they maintain it. They are very friendly and very knowledgeable.

    By Stephen R.

    It went great from start to finish.  They did what they said they were going to do when they promised it.  I didn't plan on the water heater change but they noticed a real problem and fixed it. I was skeptical at first that it was an issue but after researching the issue, they were correct in pointing it out. It was a safety issue.An after service quality check was nice to see.  While they weren't the cheapest, they were price competitive (I had 3 quotes).  I also felt that they were completely professional. I would do business with them again and recommend them to others.

    Customer Review

    By Shirley E.
    New Hartford, NY

    I wasn’t as sold on this project as my husband, but we were using propane to heat our home in upstate NY & the cost had tripled in 10 years. We have a large home & we had to find a way to get the utilities under control or think about downsizing. (Heaven forbid 2 people  live in something smaller!!!) My husband is good with figures and was able to convince me that the payments would at least be fixed and we would have it paid off in a reasonable amount of time. It would be hard to compare it to your payoff time because we had solar panels installed at the same time so we are pretty energy independent now. (In fact, the utility company paid us over $600 last year when all was totaled on the electric use. ) We’ve gone through two winters now with the geothermal heat and we haven’t had to use the back-up propane in either year. The only negative that I can express is that when it’s below zero outside my floors don’t warm up as nicely as they did with the propane in-floor heat. Halco warned us of that because the geo heats to 120° instead of the higher temperature that the propane heated. Halco system & service before, during and after has been exceptional. The entire system, including the solar, could have been such a mess, but they were careful. They came back twice to regrade where the geo was drilled. I ordered beautiful cast bronze grates because I said if I was going to have holes in my floors again they would be good-looking. I told the project manager what I wasted and he handled ordering and installing them. (Because they were not in the original estimate, I had to pay for those out of pocket.) The lead installer has been to the house a few times because we have had problems with the upstairs heat. Part of that is because we didn't really understand the way the system works. We keep the upstairs heat down most of the winter because it is unused now that the kids are moved out. But when we do want to heat it we have to bump it up a few degrees at a time or else it turns on the boiler. He installed the newest & best thermostats to help us use the system more easily and there was no extra charge for them or his labor.One thing I do like is that the air-conditioning is gentle. I always hated the way air-conditioning is icy cold; tis isn’t. We seldom use it but when we do, it’s great.

    Customer Review

    By Barbara D.

    They have been extremely thorough, very professional, and very nice to work with. I feel like I can trust them. They gave me a whole list of previous customers and said I could contact any of them, which I did and got 100% positive feedback. So, I felt like I was in very good hands. They have been so good that I have decided to use them to insulate the house and put in a geothermal heating and cooling unit.
