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.

I needed my gas fireplace cleaned and Christian showed up from Hamco! Christian was extremely pleasant, talkative and even loved up my German Sheppard ! Christian worked away doing an excellent job cleaning out the fireplace leaving it sparkling! Christian also gave a great tip on what to use on the glass and where to get it!

We had Hamco supply and install a new residential boiler and indirect water heater at the end of September and could not be more pleased with the result. Jordan, the estimator, patiently explained our equipment options, provided references for work done in our neighbourhood, and responded promptly to further queries. The price he quoted was far below that of other firms. As residential jobs go, this was a large one and a crew of four was here for two long days getting it done. Under crew leader Justin’s management, the job went very well and any questions of ours were addressed immediately. Clean-up at the end of the job was well done and all scrap (two old boilers, a water heater tank, piping) was removed. Our home was left in excellent condition. With this review, we want to thank Hamco for a job well done, and wish to encourage potential customers to hire them. We would use them again without hesitation.

I've dealt with HAMCO for a few years now and I've always found their service to be honest and reliable. I recently had my tankless water heater de-scaled by Najim, one of their techs, and he was fantastic! He took his time, paid attention to detail, was clean and courteous. He even took a look at my furnace and made an adjustment for free! Highly recommend Najim and HAMCO overall. They might be on bit of the expensive side, but you get what you pay for really....

We have an older boiler furnace and I know it's in good hands with Joel and Cam. Joel is so knowledgeable about the furnace and the two of them worked tirelessly at a recent long needed cleaning appointment. Joel and Cam are incredibly respectful and a pleasure to deal with. Hamco definitely has my future business!

I had my furnace and AC units serviced by Christian and Cameron, and the maintenance was thorough and professional. The technicians arrived on time, were friendly, and clearly knew what they were doing. They cleaned and inspected all key components, making sure everything was running efficiently. I appreciated the clear explanations and honest feedback about the condition of my systems. Overall, the service gave me peace of mind heading into the new season.

We had an excellent experience working with HamCo for our new heat pump installation. From the very beginning, Andrew guided us through every step of the process — from choosing the right unit for our home (we went with a Daikin heat pump/furnace combo) to walking us through budget details and keeping everything honest and transparent. When we decided to also add a hot water heat pump, Andrew made that seamless too.He was incredible with the paperwork for the Ontario government rebates, making sure we had everything in order for both the heat pump and water heater. The installation itself was smooth and even finished a full day ahead of schedule. The team removed and returned our rental hot water heater, handled the refund process for us, and kept the house spotless throughout. Every installer we met was polite, professional, and clearly knew their stuff.It’s been about a month since the install, and everything looks fantastic and is working beautifully. We couldn’t be happier with the results and highly recommend HamCo to anyone considering a heat pump.

Veronica and Shamar did a superb job for us installing a Daiken ductless heatpump in our 14th floor condo. They laid out drop sheets and were in and out in less time than we anticipated. We had two issues with the installation as they were working and Veronica made on the fly adjustments which made things perfect for us. Best of all the unit runs quietly and is keeping us c-o-o-l. Thanks. Shelly and Ray

I have dealt with Hamco for many years now and have always been very happy with the service I received both from the office staff and the service men. I had a call on Friday from Steve and Stefan and they both were very professional and experienced. I will definitely be getting them to come back for my annual furnace and air conditioning maintenance check up.
