Called Hamco yesterday about our thermostat that had died. It was a themostat that we have had for 20 years (not Hamco) and it needed to be replaced. They didn't hesitate and said a technician could come the next day! Andrew showed up this morning and was extremely pleasant. He installed the new one and programmed it for us! He was fast, efficient, and friendly. I've always had excellent service from Hamco and would definitely recommend them!

Cannot beat Hamco for your Hvac needs. Polite, courteous, strait forward and honest, from the office staff I’ve talked to on the phone to the salesman and technicians involved in the installation of our new system and maintenance.

Hamco came highly recommended by one of our neighbours. An efficient and likable young man serviced our fireplace and furnace. We will be contacting Hamco again next year. Many thanks. You have a great employee.

An outstanding company with skilled and friendly technicians. They undertook the complete heating/air/fireplace restoration of my house in 2016/17 and have maintained the equipment since with knowledge and attention to detail. No service can compete with their excellence.
14:36 05 Dec 19
Service was on time, quick, and the service person was respectful and high quality

Hamco installed our Olsen furnace for Union Gas when the natural gas line arrived at our house in 1996. That furnace was replaced in 2013. Hamco had the most reasonable quote for a modulating high efficiency York furnace. Installation and maintenance are very good. I recommended Hamco to my neighbour. They also went with them.
18:37 29 Nov 19
I have had my furnace serviced annually by this Company since 2013 and have found the service representatives to be friendly courteous and punctual. This year I had some questions about a planned renovation that would include the furnace area and the service representative provided some helpful information.
21:50 27 Nov 19
Hamco's service rep Allan came to do a winter tune up on my furnace. The furnace showed a fault which was a single red flashing lite yet the furnace was operating without a problem. He did the winter tune up including cleaning the flame detection sensor. Upon completion of the tune up and testing the furnace the fault was also corrected. Allan was very friendly personable, and efficiently and did a good job of tuning up my furnace. I highly recommend Hamco and their personal for your furnace needs.
01:53 27 Nov 19
Great reliable and well established HVAC company that I have used since I purchased my A/C and furnace from them in 2015. Prompt and courteous service all the time.
19:48 17 Nov 19
We purchased a A/C unit from Hamco about 3 years ago. Excellent service! Our furnace was just serviced by them for the Winter and again, no complaints, would highly recommend this company.

Tech's were very informative, answered all my questions. Did cleaning and inspection efficiently and explained results. Very satisfied.Been a customer since 2011
16:41 13 Nov 19
Quick, tidy, efficient! Answered all my questions. Very helpful.
17:43 12 Nov 19
I have been using HAMCO as my heating and cooling contractor for about 20 years now. Always prompt, courteous, and knowledgeable. Highly recommend them.
15:46 11 Nov 19
I have been dealing with HAMCO since having my furnace installed in 2013 and have never had a complaint about or a problem with the company. The furnace works great and have only needed the annual tune-up. The crew arrives when promised and are quick, efficient and friendly. I would recommend HAMCO to anyone.
15:12 07 Nov 19
Last February our furnace stopped working after 9 good years. The service reps tackled the problem with dogged persistence and skill. After four trips with replacement parts they got it working again just as good as new, and all parts and labour costs were covered by the warranty. Now that's customer satisfaction! The warranty is about to expire so we are purchasing a service contract. The service reps are always courteous and informative. They never leave a mess. I strongly recommend HAMCO for your heating (and a/c) needs.
15:08 05 Nov 19
Hamco maintenance guys are very professional. They maintained my furnace and AC for 13 years and I am very satisfied with their work
22:43 04 Nov 19
Excellent Experience! I had called another company to come fix my furnace. They ended up shutting it down and flagging it at 9pm at night. They tried to get me to buy one at 10pm but I said I wanted a quote from another company and called Hamco.Andrew came out the next day, he arrived on time and I can't say enough good things. He's one of the best sales people I've ever dealt with for any product. I'm not surprised to see so many other reviews here mentioning how great Andrew is to deal with. It's definitely all true. He was thorough and detailed. He gave me several different options in my price range and explained each one. He wasn't pushy or demanding, he listened to what I wanted and my budget and let me choose the best unit for me. I chose one that was a much better price than the other company had quoted. The guys came to install it on time. They were courteous and did a great job. Everything was exactly as Andrew had described. No surprises, no hidden costs. New Furnace is working perfectly now. I'm very satisfied, I will definitely use Hamco again and recommend them to everyone I know.
15:48 01 Nov 19
Prompt and friendly serviceman, Andrew, serviced our furnace, explained a problem and ordered the part for us. Always good service every time we have called.

21:46 21 Oct 19
We are very pleased with our new quiet and efficient DAIKIN furnace and AC unit. Andrew clearly presented all options and associated costs to us and we chose DAIKIN due to its quality, reputation and stainless steel lifetime warrantied heat exchanger. Installation was professional in every way and very neatly done. We have been satisfied HAMCO customers for years because of the value of their products and professional service. I would highly recommend HAMCO to anyone considering an HVAC upgrade or replacement.
14:25 19 Oct 19
Friendly and competent service from Andrew yesterday on our annual furnace maintenance. This is consistent with our experience with Hamco over the 15 years since they installed our gear. Highly recommended.

Hamco has been our ‘Go To’ HVAC provider since 2009. The techs are always punctual and efficient, and although there is a very reputable HVAC company within a few kilometres of us, we continue to use Hamco since we know we will always be well serviced.
19:29 01 Oct 19
Thanks to Mike Kawa of Hamco for his ingenuity for a tricky fix of a leaking hot water heater pipe which involved carefully removing and restoring surrounding ductwork. He also replaced the cold water inlet with a more robust ball valve and corrected a couple minor furnace issues including readjusting our blower speed. All working fine now!We live in Burlington and have used Hamco services for 15 years including the installation of a York High Efficiency Modulating Furnace and humidifier, redesigning ductwork layout and dampers for better air flow, relocating and replacing hot water tank, and servicing A/C and gas fireplaces. We have found the Hamco team to be consistently friendly, responsive, and skilled in addressing all of our HVAC needs and highly recommend.
21:04 30 Sep 19
Bought a York furnace from Hamco 15 years ago, have had it serviced under warranty and now past warranty by Hamco and have been very happy with furnace performance and with the service provided. Staff in the office and on service calls are very efficient, friendly and knowledgeable. Thanks everyone!

Excellent service all the time from Hamco. Thanks.
14:49 30 Sep 19
Have been with HAMCO for five years now and have had nothing but excellent service. We found the salespeople friendly, informative and not at all pushy. So glad we went with them. We get yearly preventative maintenance and the service people are always polite, tidy and full of good tips to keep the furnace running well! Can't recommend them enough.
14:10 30 Sep 19

Hamco has serviced our furnace and air conditioner for the past 10 years since they did the installation. We are very happy with the service we received and the polite and professional service technicians.All the staff are great to work with. We recommend Hamco highly.
15:44 26 Sep 19
Contacted Hamco for an annual check up of A/C & Furnace; "Andrew" was on time, courteous and considerate about keeping working area clean.Will use their service again in future.....
17:06 19 Sep 19
We had our furnace and A/C installed 10 years ago and serviced by Hamco each year. The annual service has been consistently great. Every representative has been friendly, respectful and always on time. At my request a new filter has been provided and installed, saving me the trip of visiting the office to purchase. The details on the invoice are thoroughly explained and any questions answered. I would recommend Hamco to anyone looking to purchase a new furnace.
14:41 17 Sep 19
Locally owned Hamilton business that is honest, delivers great service and provides quality advice for keeping our heating and cooling systems running efficiently. When it is time for regular maintenance or there is an issue with my heating and cooling, I only call HAMCO.
15:33 13 Sep 19

Technician was very professional. Always great service for the last 5years.
23:54 09 Sep 19
These guys did a great job on the install of our furnace and AC in June 2018. Before the install we met with Andrew and he walked us through everything. Our house is over 100 years old, so he even helped us put in a new air return and move the AC to a better location where the lines didn't get in the way like they did before as they travelled through the basement. The final job was super clean, and even the exhaust and intake vents were done nice and neat on the exterior brick. They showed up when they said they would, on time, and left everything very clean. Andrew also helped us get quite a substantial rebate as well. I would definitely recommend Hamco if you're thinking about a new furnace or AC install.
22:58 09 Sep 19
Hamco installed a new furnace and air conditioning unit into our house in 2017 and the sales person (Andrew) did a fabulous job explaining the needs of our house and helping us select something that was appropriate. The installers did an amazing job. They even placed our new unit in a different area of our property so that it would interfere less with our day to day life. They were also fast and thorough.This year's maintenance call is my only questionable experience. The technician had BO and before he left, he offered me 10% off for a review on Google. I received 10$ off of the maintenance only which feels like a bait and switch. Also, I'm pretty sure you can't offer a discount for a review.Hamco is 100% the best experience our family has had with ANY HVAC company we've ever had to work with and I LOVE that you purchase your own furnace and AC unit. The industry seems to have become VERY predatory nowadays with revolving fees that you can't get out from under. Thanks Hamco for maintaining high standards.
17:12 09 Sep 19
Great on time service. I've put in a ductless a/c unit as well as a humidifier and each time the tech's are professional and clean up afterwards. Sales Rep Andrew is great to deal with, will email me back with any answers I may be looking for. Highly recommended!!!
17:40 06 Sep 19
Andrew came this morning to check out the furnace and fireplace for winter use. He was very friendly, efficient, and offered good feedback about both appliances. Excellent Service!(How do I post this review!!!)
14:23 06 Sep 19
Always have a very pleasant experience with all employees. Your service is outstanding and always dependable. Thank you Hamco. Your the best.
15:03 04 Sep 19
Andrew came to do the maintenance on my heating and cooling and fireplace. He was quick and polite and friendly.
20:50 29 Aug 19

I have been a loyal customer of Hamco for 9 years, when i purchased my air conditioning unit and furnace, i have not add a problem yet, great customer service and awesome service from their technicians.
00:25 28 Aug 19
This is a family owned business that delivers top notch service. Right from the time they updated our heating, cooling and hot water systems 10 years ago we have enjoyed prompt, reliable and professional service. We experienced more of the same with the latest service and repair just provided by Nolan.
15:41 26 Aug 19
We just had a new Daikin 2 stage furnace installed in our home and are very pleased. Their technicians were very skilled and they left our home neat and clean after the install.The whole experience from sales to install was very professional.Thank you to the folks at HAMCO

We just had the annual maintenance done on our AC unit. We've been doing so for the last 3 years. They are always great at fitting us in and have always provided service in the designated time frame. They offer 3 to 4 hour windows so you don't have to waste your whole day waiting for them. Great service!
16:52 16 Aug 19

14:36 12 Aug 19
Great job on the service today - annual inspection completed quickly, guys were nice and professional. THanks!
16:21 09 Aug 19
HAMCO, the best Gas/ AC installation and service company in Hamilton. They have fixed un-even flow of air in different rooms in 2017 to my satisfaction. Today their tech was here for service. He did his job very nicely and timely. I will definitely recommend to my friends for the service of AC/furnace units.
14:43 09 Aug 19
Great service, friendly demeanor. Arrived when they said they would and completed the maintenance fast and efficiently.
11:15 26 Jul 19
On July 23rd we had a new Daikin gas furnace installed , oil was our previous furnace which was paired up to our existing Daikin A/C that was installed a couple of years ago by Mike at Hamco'Mike was back with Greg and Anthony to install the furnace and all the accessories that we ordered with it.It was a long day for them which ended about 7:00 PM and the guys did a phenomenal job.I would highly recommend Hamco and the crew that we had, great guys.And a thank you to John V. for putting this package together for us. Carole and Doug
22:30 04 Jun 19
I called Hamco to rent a water tank last Friday. I was told they could be at my home Saturday morning but I asked for Monday. On Monday, Murray and his helper Reese arrived on time and were the most professional techs we left to get groceries. When we arrived back at our home Murray and Reese told us we would have got water in a half hour. If you weren't looking you wouldn't know they were working in the home.Thanks Hamco from Josie and Taylor.Great looking job from start to finish.
20:30 31 Jan 19
New HE furnace February 2018 and new tankless May 2018.
22:49 10 Dec 18
Very pleased with HAMCO. A wonderful company with a knowledgeable team that are fast, efficient and professional. We had our furnace replaced with a combi system and are very happy with the upgraded results. Service from start to finish was stress free from HAMCO. I couldn't recommend them more, especially if you have an older Hamilton home.
23:37 06 Dec 18
These people are the real deal. I had a new furnace installed and everything from the quote with Craig to the installation with Murray was genuine and clear. No nonsense, no rush job, no cut corners. The work was perfect and the furnace has been functioning trouble free. This was simply a painless experience. I will be using them again! Support Hamilton Businesses!
19:38 25 Sep 18
Great customer service and products
20:39 20 Sep 18
Call these guys first!!! I had 2 other techs out to diagnose and both said they couldnt help with the type of condo unit I have amd that the whole system needed an overhaul... one visit fr9m HAMCO and all is sorted without any replacement parts required!!! I cant say enough on how thankful I am.
18:16 27 Aug 18
Great company. Great warranty. Fantastic people. Have already recommended HAMCO to friends! Thanks you!
19:19 02 Aug 18
I'm very well satisfied with HAMCO. In a day in age where you are unsure whom to call for service, HAMCO has been reliably in the business for so many years, I can't even remember. The people who come to my home are always more than polite, and very helpful. The staff have been in the office for a long time, and its a very nice friendly reliable company to deal with. They installed my new air conditioner 5 years ago, and service it every spring. You won't regret having your service or installation by them.
19:28 27 Jul 18
Hamco responded quickly when my air conditioning broke down and got the problem fixed within hours of my call to them. The service men were friendly and professional. The repairs were done quickly and efficiently. I wouldn't call anyone else to maintain my A/C and heating and would have no hesitation in recommending Hamco to others.
12:48 09 Jul 18
Recently we needed a new AC, furnace and water heater. So we called Hamco again as we had them install equipment in our first home. Again the service Craig and the installation team at Hamco performed was top notch. Another great job! I won’t hesitate to call them again for our next property.
19:27 18 Jun 18
Absolutely exceptional service on my AC installation right from the quote to the end product. Would highly recommend them to anyone needing AC or Furnace work. Cheers.
01:26 15 Jun 18
Had a great experience. Quick, efficient and friendly service. Will book again without hesitation. 2 thumbs up
15:54 13 Jun 18
I had a tech do a annual inspection and it was first class !!
19:03 23 May 18
Hamco's technicians are so nice! They are knowledgeable and patient, highly recommended.
22:03 24 Nov 17
I recently needed to upgrade my air conditioning at my place of business and John and his team were amazing. He was the only guy out of 5 or 6 quoted who actually said he enjoyed doing the job I was looking to have done. I needed a 3 ton ductless unit and he really delivered. First of all his price was great! Less than half of his competitors. I don't usually go with the lowest quote but John and his team came 3 times to inspect what needed to be done and I was confident he was the right company to go with. He even tried to save me money by not making a hole in my roof but my landlord insisted we had to make a hole in the end. The installation was done quickly and his installers were true professionals. I liked them so much I had them come on another day and install a new water heater. John and his team care about their customers and they take pride in doing a great job at a fair price. This is not easy to come by in today's world.
21:56 24 Nov 17
We were first introduced to Hamco Heating and Cooling when we needed a quote for a large ductless air conditioner to be installed in our tanning salon. We already had several quotes and the range in pricing from one to the next was vast. John from Hamco was very helpful and had some great ideas for our unique application. His quote was very reasonable. They did the work right away and they did an excellent job. Very professional and efficient! He just so happened to be around when our hot water tank broke so within days he had a new one of those installed for us as well. I can't say enough good things about John and his team. 5 Stars.
15:05 31 Oct 17
HAMCO has an excellent customer service, work ethic and Response time on any service call. Highly recommended!

An exceptionally great company that pays attention to all the details and offers top of the line products for home heating, air conditioning, fireplace needs. The company through Jordan and his team, completely updated my 100 year restored home installing a new gas boiler (removing the old oil system), central and ductless air, water heater, gas heater for the garage, and BBQ lines for the outside. All the products were fully explained, and when in doubt, were readily available to assist with any of the questions. They ensured that all the new equipment was in proper and safe working condition. Without a doubt, I would recommend the company to any person who inquires about the changes I have made to the house. Those who have seen the changes were amazed at the installation of central air in the main part of the house that did not destroy the historical character of the home. An absolutely super team to meet all your household heat and air needs. You can have confidence when you use HAMCO.
14:53 15 Aug 17
Just had HAMCO do a furnace and an A/C install. Old units were over 30 years old. Andrew gave me a complete quote on two different brands and I chose the Daikin. Pricing was fair and the install crew took only 6 hrs to remove the old units and install the new ones. Disruption was minimal and the crew was very professional. Totally pleased and would recommend to anyone that needed this type of service.
20:42 19 Jul 17
Best in the city! Highly recommend this team of outstanding professionals 🙂 thank you Hamco
12:33 06 Jun 17
Very professional. Great communication.
15:53 18 May 17
HAMCO has been our preferred installer of out heating and cooling equipment for over 35 years. They installed our first high efficiency furnace 35 years ago when we first built our home and then installed out latest new furnace and air conditioning system almost 9 years ago. They also service our equipment regularly. All their personel are prompt, efficient and professional.
23:03 17 May 17

20:01 05 Apr 17
Great company, great work, fair prices. Super happy with all the work done in my house. New high efficiency boiler installed and had a rad run to the kitchen where we had no heat. I got lots of quotes Hamco came the next day prepared with information to suit our needs discussed over the phone. They didn't try to upsell us or push things we didn't need or want like other companies who came to quote. Highly recommend them!
18:17 08 Sep 16

01:29 05 May 16
We had them supply and install a furnace and ac system. They had to start fresh on this system. They did a GREAT JOB. It was for a rental prerperty. It's worked great for the last year and is by fat the best furnace we have. They recommended a Baxi boiler. It hardly uses any fuel. I cannot believe how weel it works. It is a combo boiler and domestic hot water unit. It is truly a great boiler. I also had Hamco do furnace replacement on a old furnace. It was done fast with no problems. I had 4 quotes before I went with Hanco. They were right around the same price but they did the job great and faster than everyone else said it could be done. Everyone told us it would be 2 or 3 days but Hanco came in with a bunch of guys and got it all done in 13 hours. That is true great service. Getting the job done fast and has worked perfect all winter. They do a great job at a fair price. I cannot ask for anything else.Thanks for the great service
11:53 22 Jul 15
We had used Hamco a few years back for our home . The furnace and hot water tank were replaced by them .We were very satisfied with every step of the way .Started with Andrew giving us a quote and lots of options .The follow up service after the installation was superb. A true sign of a great service company .But the duct work and house was only 43 years old ! My business has duct work that is 75 years old and I wasn't sure how well they could handle the task of replacing the old oil furnace with a new gas one.This very challenging job was handled Very smoothly .Hamco stuck to the original quote even though the installation required customized duct work for the hook up .They advised me of the proper furnace and AC . Both are perfect for my custom needs .Well done Hamco . Thanks kindly ,Ron
