HVAC FAQ

Why is ventilation important for proper indoor air quality?

At one time, it was possible to achieve natural ventilation in our homes by simply opening a window. However, with growing concerns about rising energy costs, we have been busy making homes “tighter” from an efficiency standpoint. Armed with weather stripping and caulk guns, we have eliminated air leaks from our homes. Unfortunately, that means contaminants have no way to escape.

Pollutants in your home’s air can cause poor indoor air quality, which may cause dizziness and headaches, plus aggravate allergies and asthma. That’s why Daikin offers ventilation systems that help remove contaminants by exchanging stale, recirculated indoor air with fresh, filtered outside air.

Najim was very knowledgable and he quickly diagnosed a serious problem with our furnace. He reinstalled the venting, put in a new motor and thermostat. He was very efficient, polite and our furnace is working perfectly again! I highly recommend HAMCO and technician Najim and will definitely call them for future service needs. Thanks!

We've received good service from Hamco for many years. Today a new service person named Najim arrived to do the regular maintenance on our furnace. He was thorough, friendly, answered our questions clearly and made sure we understood how everything had been updated. I have no difficulty recommending this company.

I recently needed some help and the technician who came was great. He explained everything that he was doing, even gave me some tips to be more efficient. These kinds of calls always make me anxious, worrying about how much the bill will be? Will I get a good technician who is honest and knows what he/she is doing? All went well and I want to thank Nolan T. for his professionalism and easy-going manner. Thanks Nolan and thanks Hamco!

I recently had Mike from Hamco perform my annual maintenance and I’m extremely satisfied with the experience. From the moment he arrived, he was friendly, professional, and clearly very knowledgeable about heating systems. Mike took the time to explain everything he was doing and offered useful tips to help me maintain the furnace through the colder months. His thorough work gave me confidence that my furnace is in great shape for the winter. Mike is definitely a valuable member of the Hamco team, and I’ll be requesting him for future service!

We had Hamco come in and service my father's furnace. The technician that showed up, Mike, was extremely professional, knowledgable and talked through the issue with myself and my father.

I have already recommended Hamco to all my friends and family.

Christian from Hamco came by to do an annual maintenance on my furnace. It is a brand new furnace that I bought from them last year, but doing the yearly maintenance increases my labour warranty. Christian was efficient, very kind and punctual. I will be a longtime Ho customer

Joan French

18:37 13 Sep 24

After replacing our furnace and installing a central air unit with Hamco we've had nothing but excellent, attentive service that is reasonably priced and achieved both on time and with great courtesy. Christian just performed the yearly maintenance on both units, and thanks to him we're all set for winter! There was an issue with a part he quickly and efficiently replaced, and I'm certainly happy to know it now instead of during the first cold snap.

Mary Smith

17:58 13 Sep 24

Air conditioner service required due to non-cooling. Called Hamco first thing in the morning and fixed early afternoon. Exceptional courteous service beginning at reception who booked the service and by Najim, the onsite technician. Najim was amazing, very professional and knowledgeable and he looked after a few extra items while he was here - cleaning, taping gaps in duct work, etc. Thank-you Najim!

connie marshall

19:06 24 Jul 24

Excellent service! Called them for a 2nd opinion, and boy did they deliver. They followed up with manufacturers of our heat exchange and found out it was under warranty. Going the extra step, saving us over $2400 based on quote from the other guys to replace. We know who we will be buying our new system from when needed. Thanks Najim for going the extra mile!

I should have called HAMCO right from the beginning! Me and my family suffered with no AC for a week during the hottest days yet this summer! Corey from HAMCO came bright and early this morning and solved the problem. Very professional, knowledgeable and respectful, he got the job done in no time. Thank you Corey and HAMCO!!!!

Peggy French

15:21 09 Jul 24

Fearing an exorbitant bill, I reached out to HAMCO for a Saturday service call during another heat wave. Christian from HAMCO promptly returned my email and explained the charges, both 'real' and potential. He arrived when he said he would (rarer than it should be!) and immediately set to work. He efficiently and effectively diagnosed the issues and had a well-stocked truck that allowed him to fix both issues and restore my air conditioning. Thank you, Christian! The price was very reasonable and below what I expected to pay under the circumstances. I will continue to recommend HAMCO! Strangely, my two neighbours to the north have both had their air conditioning fail over the last 10 days and neither received timely nor exemplary service from their providers, who were NOT HAMCO.

We have used Hamco for our pharmacy business for many years. They are the reason our customers and staff are always kept comfortable in the store. This year, they even helped solve a tricky problem with our compounding cleanroom airflow and pressure balance. Just awesome guys. Wish I could give more than 5 stars.

Faisal Khawaja

23:33 04 Jul 24

My AC went out last week, in the hottest days of the year. The Hamco tech showed up on schedule, fixed my AC quickly and professionally. And the price was right. This is why small, family-owned businesses are the best! They have a customer for life.

Michael S

21:47 27 Jun 24

Christian came to my place today and he was very friendly, professional, and helpful. He listened carefully to my concerns. He was patient and not condescending while he explained how the AC worked. He was able to find an important adjustment that was necessary and now it's blowing twice as cold!

There I was… with an rv hot water tank that needed to be replaced and some propane lines that were beyond sketchy. I didn’t know how to resolve these issues and who would take on such a project. I reached out to Hamco and although rv trailers are not something they usually tackle, they cared enough to listen. They understood I needed help and they took this job on. Right away, Nolan was out to do an on-site inspection to get a better understanding of what was involved and what needed to be done. He was so professional, personable and knowledgeable. He got right to the task at hand and understood quickly what needed to be addressed. A date was easily booked through the helpful and courteous office team. On June 12, 2024 Nolan returned and again, wasted no time diving in and getting the old hot water tank out and installing the new. Repairing the propane lines and testing and checking all the new system. I can’t thank Nolan, Jordan, Veronika and the rest of the team at Hamco enough for caring, going the extra mile and helping me out of a real jam. It’s not always easy for a service company to achieve the highest level of service that it’s customers expect… but Hamco sure did reach it here.

I have used Hamco service for 25+ years and have a Hamco installed furnace & air. I use their service for both spring & fall maintenance. They have been very helpful to the point of helping to keep my very old heating system as long as possible. Recently I had the spring maintenance service & there were a couple of problems after it was completed. I spoke to Tara who was very helpful & patient with my explanation of what was happening. A couple of days later Mike came to investigate the problems & quickly solved the problems & explained what was happening. They were both very helpful and considerate.

Gail Bauer

19:06 26 May 24

A great company to deal with!!! Tara helped direct me to the right person for ordering a hot water heater which was installed by Adam and Veronika. I have been a long time, happy customer.

It feels like Summer is already here and so thankful that we purchased our new York A/C from Hamco a few months ago. It’s running great and keeping our house nice and comfortable. We have been a customer for many years and can’t be more pleased with Sales (Andrew) Service (Shane) and Customer Service (Tara). All so friendly and knowledgeable.Quick story: Two winters ago my wife and I were visiting my daughter and her family in Switzerland. We were there for 2 months and while away we had a good friend checking the house on a regular basis. A month into the visit I received a text that there was an issue with the furnace. The condensate drain line was leaking and had to be fixed/replaced asap. A 6-hour time change made phoning a challenge however, after talking with Tara and Shane we were relieved and the repair was made the next day. Where do you get Service like that!Thanks again to the HAMCO Family!Regards,Charles D. Shields

As a House Manager for a larger private residence with an extensive HVAC system we relied on the Hamco team to service our system seasonally, as well as assist when there was an issue.

April 2024: Just a quick post to thank the accounting lady at Hamco (Cherryl) – the one who asks for money. I want to acknowledge her pleasant and friendly attitude. Last year, when I had requested an invoice for a recent service call – through a miscommunication, she pulled out our last 10 years of past invoices, and sent them all to me. Now who else would do that – and still be smiling? Only Cherryl. Thank you!Jonathan at Hamco just completed our annual (June 2023) York A/C maintenance. He went above and beyond - which is always the case with Hamco and their technicians. My thanks go to Shane and his crew.Hamco just finished this year's (2021) annual maintenance on 2 furnaces. Technician (Eric) did a bang-up job - knowledgeable, efficient and courteous - thank you !!Once again Hamco earns its stripes. Had them in for regular furnace maintenance. Andrew M. was everything you would want in a technician - skilled, professional and pleasant. Been using them for many years and highly recommend them. Two thumbs up!We had a noise problem with 1 year old York AC. Shane addressed the problem promptly. Within a day, technician Andrew was on site, diagnosed and fixed the problem within minutes. Thanks to both

Earlier this week Hamco replaced my gas furnace and air conditioner with a new multi stage furnace and heat pump. The team was led by Shemar assisted by Nick, Veronika and Tony. They were courteous and efficient, and the work of removal and installation of the new system went smoothly. They did a great job of cleanup in the work area, and outside where the hear pump unit is located. Thanks to the installation team, and to Andrew who did the upfront work of finding the right solution for us.

Our old rental hot water heater burst, which left us with a bit of a flood and no hot water. We phoned around to the big box retailers to purchase and install a new hot water tank. The install dates were anything from 7 to 14 days wait. I phone Hamco, and they sent a rep that afternoon to estimate the job. The install was completed next day in 2 hours. Excellent service and competitive price. Highly recommend.

Elisabeth Gedge

12:45 15 Mar 24

Yesterday the Hamco team replaced my furnace and air conditioner, and did a wonderful job! Led by Shemar, they were courteous and efficient, and the work went smoothly. Shemar added some unexpected touches - a handle for easily removing the filter, and a pouch for storing the manuals - very helpful for a forgetful and arthritic senior! He helped me set my thermostat and talked me through all decisions made. Thank you to a great team: Tony, Jonathan, and Shemar, and to Steve, who did the diagnostic work on the old furnace and a/c. Congratulations.
