HVAC FAQ

Why is my system freezing up?

Several factors can cause system freezing. Most need to be corrected by contacting HAMCO.

There are a few things you can do to help prevent your system from freezing up, and also to do if you have found that your system is frozen.

Dirty filter

Check that filter! A clogged air filter will cause lack of airflow. Airflow is necessary to keep cold air moving through your duct work. If your filter is clogged none of the warm air from your home is passing over your refrigerant coil, leaving the refrigerant inside cold for too long, thus ice build up occurs because the moisture on the coil freezes.

After replacing or cleaning, you can speed up the thawing process by turning the system off and turning on the fan. If you have a heat pump system, you can try turning the system to heating mode until the ice has melted. After the ice has melted, switch the system settings back to normal. If the system refreezes, contact Hamco to correct the problem.

Low refrigerant

In some cases, freezing is caused by a leak in the refrigerant lines. Weak solder joints, friction from piping rubbing or vibrating against an object, open valves or loose fittings are all factors that can cause leaks. When determining whether to have the system repaired or replaced, the age of the system and the nature and location of the leak are important considerations.

Dirty evaporator coil

Over time, the evaporator coil will become dirty. When this happens, you will begin to lose airflow, slowly enough that you probably would not realize it until it freezes up or cooling performance is compromised. At this point, you will need to contact Hamco to correct the problem.

Defective blower motor or relay

A blower motor not running at the proper speed or not running at all is another factor that can cause freezing. The motor operation may be intermittent, starting at full speed and slowing down after it heats up. Or, a relay could cause it to start one time and not the next. In either case, you will need to contact Hamco to correct the problem.

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!!!!

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.

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.

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

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. The team is reliable and knowledgeable but the star of the team is Cherryl who was always a delight to work with. Highly recommend.

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

We had our furnace, ventilator and some ducting replaced during a renovation of our condo - a major project. The team did a terrific job of removal and installation. The whole HAMCO experience was excellent, including the "back office": Cherryl in Accounting was super responsive throughout the process and is a really excellent rep for the company. Thanks, Cherryl. Let's hear it for Accounting!!

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.

Well I waited a while to write a review til it got "REAL cold". I have to say the HEAT PUMP/AC PUMP we had installed in the summer did an outstanding job dealing with the entire attic area with ease. It was so comfortable up there (when it was like 40+ degrees outside on those heat wave stretches we had here in old DUNDAS) we just wanted to be up there more often, also noticed the air was very comfortable and clear. Not too dry or humid, kinda just perfect.Our house was built in 1903, pretty typical Edwardian style, long, skinny and REALLY tall. Attic open from front to back of house.NOW that its COLD, prior to this HEAT PUMP install, our attic was an ice box. Tough to enjoy, NOT A PROBLEM NOW THOUGH !!! The heat in there is excellent!! It's just quietly keeping us at 24 degrees or so. The outside unit is so quiet I have to lean into it make sure we are running. Incredible really!! HYDRO bills do not show huge increases. I think we are quite similar in historical billing actually, be being more efficient in other areas. Ii.e. weekend laundry only (OFF PEAK), less fancy lights out back no one really looks at too much.The installer crew were in/out in about 7 hours. Great crew!!"ANDREW" was spectacular from start to finish with his knowledge, confidence and professionalism. I had 3 or 4 discussions with hvac folks, and clearly ANDREW knew the job better then the rest, so we signed with HAMCO!Thx folks, I've recommended you several times.B

Just had a ductless AC installed. Starting from the sales representative Andrew to the technicians who installed the unit, Ainslea, Shemar, Nick and Tony, we couldnt be happier with the service we received from start to finish. Professional, friendly and efficient, it was a pleasure having them in my home. Hard working bunch and will definitely be referring this company in the future. Thank you Hamco for the amazing job!

Cindy Labbé

19:33 09 Jan 24

I would highly recommend Hamco Heating and Cooling Ltd. We had used their services to maintain our old furnace however when we woke up with no heat one morning, we were very worried. The technician came without two hours. Unfortunately, it was time to replaced the very old furnace and Bill came right away to next day to give us a quote on a new furnace. Our installation took place the following day and our installers Justin and Nick did an amazing job and were very professional. Thank you to the whole team for caring and making sure we were not left out in the cold for very long.

We have been working with HAMCO in Hamilton, ON for over 15 years, to install a high efficiency boiler and a water heater. They have always provided top quality, reliable service. Recently we installed a heat pump in our house (which is almost 100 years old and has hot water heating). We installed 4 heating/cooling units, one on each floor operated by one large condenser to reduce our carbon footprint and hopefully reduce our gas bill. The installation team of 4 eneregtic young technicians (Veronika, Najim, Josh and Nick) were a delight to work with. They were effciient, fast and completely dedicated. They made sure everything was done to a perfection despite cold weather outside. Thanks very much to them and we recommend them higly to anyone who is considering a heat pump installation.

Conor Bell

Two technicians ( Najum and Shamar) installed a new gas furnace and hot water tank on a rush basis since my old one failed. They worked well and solved a few install issues quickly. They tidied up afterwards and explained any questions I had thoughtfully and politely. Easy for me to recommend these gents and Hamco.

Very positive experience working with Hamco for our Daikin ductless system. Andrew was very informative and detailed in explaining the best heating solution for our sun room. Murray and the team were fantastic and consulted with us during every step of the installation process. The job was unique and challenging, but it was completed professionally and on time. Couldn't be happier with the results!

Recently had our Furnace replaced after it was deemed too expensive to replace a fan whose cost was the equivalent of 50% of a furnace. Veronika and Rick installed our new furnace updating specs that had changed. Excellent job all round our second furnace from Hamco

Lori Gamble

14:48 18 Sep 23

Today Christian came out to do the yearly maintenance on my furnace and a/c. He was friendly and very efficient. I’m always pleased with the service received from Hamco and from my Daikon heating and cooling system. I appreciate an honest company, one that doesn’t have to ask permission to up sell you on equipment you don’t need.

Bruce Watson

Christian came out on the long weekend to help us when our air conditioner broke down. He was efficient and went above and beyond to find the parts and get us cool again!

Kathryn Lee

15:23 01 Sep 23

We've been dealing with Hamco for years and it seems like they've always gotten something wrong. Our hot water went out recently and I actually called a few places but they were all busy so I went back to Hamco. Today they sent Nolan and I couldn't be happier. He was great. Fixed everything, did a few extra things and made sure everything was right. I so appreciate his hard work and will ask for him specifically in the future.

John Vengris

18:45 22 Aug 23

After years of putting up with a sometimes functioning thermostat it was successfully replaced today. Jonathan was here as planned and was courteous and professional in resolving my issue. Have had Hamco as my furnace and air conditioning go to for years without a glitch. Highly recommend! John

Kathryn Johnson

14:09 14 Aug 23

Jonathon, the technician, was very efficient, thorough and respectful.

Ivan Q

18:40 02 Aug 23

We had a good experience with HamCo for our AC replacement, that we contacted them again regarding our furnace! We thought we could get a couple more years from the furnace but it too needed to be replaced. Again it was another quick turn around from our initial call to Laura, quotes with Bill, and to install with a great team of technicians.

j morris

20:13 28 Jul 23

Our experience using Hamco to install our air source heat pump last year was great. Andrew is very consistent in his messaging about the pros and cons of the new system and the quote that he put into place at the beginning of the process remained unchanged, despite some changes in the overall plan. From our experience, Hamco seems to be running an honest operation that cares about customer satisfaction. We are happy customers.

Jessica Simpson

19:38 27 Jul 23

In the past 2 years we've had Hamco install or replace a few things at our home and they always do an outstanding job. Their entire team is excellent - friendly, professional, and extremely knowledgeable. Thanks Hamco!

Had a 1T ductless Daikin Heat Pump installed to help heating & cooling in our Durand 1890's brownstone. They've attended to the needs of this house through a number of owners and many many years.From the professional (and free) sales call from Andrew to the great install team of Veronica, Josh and Corey I can highly recommend this local company to you.

My Parents have been using Hamco since the late 80’s. We are completely satisfied with the on going excellence with all the service. The techs are professional and persistent in solving our heating and cooling issues.So much so we purchased a hot water heater we had no idea they did that but the tech advised us on the type and size we needed. That was also an excellent install. I’m not really a google review type but when it’s good you need to tell others.Give Hamco a try I know you will not be disappointed.

Always responsive, on time and great service. We have recommended their service and installation to numerous friends, and will continue to do so.
