Pleasant and Professional Installation


“Hello Mark,


Just a quick line to thank you for your initial inspection of our situation for installation in our home of a new gas furnace using current ductwork! We appreciated your expertise and the manner in which you dealt with us.


And thank you for sending the “A-team” to do the installation! Adam could not be a more pleasant and professional installer, and Xavier was an excellent assistant making many trips up and downstairs for parts; and the two worked quietly and efficiently on the job. They were respectful of the nature of our home, and left things looking very good at the end of each busy day. There is not a minute of downtime with these two!


Thank you, too, for allowing Adam time to install a second thermostat even though this was not part of the original order.


And our understanding would be that since the air conditioner can’t be tested adequately now, the contract price you have given us will cover a spring inspection to make sure the system is fully operational.


Many thanks again, Mark.


Warmest Seasons Greetings,

(We thought this complimentary close to appropriate for a heating firm!)”

Valued Advice and Service


“Hello, dear Zed-Air Heating & Air Conditioning folks!


On record Ontario heat, this old lady started off a Facebook message today with, “I am lucky that Zed-Air Heating & Air Conditioning and Blair already rhyme – now I just need 12 more lines to create a love sonnet to the company and the tech who came out on Wednesday to rescue me from heat prostration on Westdel Bourne.”


I am home alone, looking after two aged pets – and in the hottest week of the year, my A/C stopped blowing cooling air. Husband was up north, and the installer of our HVAC system nine years ago was impossible to find. On the advice of my adult son (Zed-Air Heating & Air Conditioning installed the heating and cooling in his first marital home on Thistlewood), I called YOU.


On Wednesday morning, you said no guarantee of arrival time could be made – but by noon, I received a call from Blair that he would arrive within the half-hour. He did – and with courtesy, kindness and patience, he tested the main outdoor unit and the area around the heat exchanger, and decided that a plugged filter and lack of maintenance had resulted in a major freeze-up of my system. His patient explanations of how the system works, why a fan in “on” position works best with our two-storey house and why deflectors should be removed from the registers during the summer made sense. I followed his suggestions – and today, the house is cool, dry and comfortable.


The bill was MORE than reasonable, his advice was valued and his gracious manner was a credit to your company. I am so very glad that word-of-mouth from my son led me to Zed-Air Heating & Air Conditioning and your skilled staff. Should any kind of HVAC service be needed in the future, you will be my very first call!” 


- Daina J.

Very Pleased


“I’m very pleased with the service I received. The technician looked after my Tempstar® furnace and my Valor® fireplace. This is the first time I’ve used Zed-Air Heating & Air Conditioning, but it won’t be the last. Thank you!”


- Margaret P.

#1 Referral for HVAC

“I am a residential and commercial building inspector, owner of ThermoPhoto Inc. Building Inspections. I had the pleasure of working for one of your employees some time ago, Blair Surette. I was very impressed by his attitude, knowledge and zest for the profession. I have taken the liberty to make your company my number-one referral for HVAC. Blair has supplied me with a number of cards, but I will be in touch when I run out. Have a great day!”

- Trevor P.

A Job Well Done

“Thank you for the installation on March 27. Your installers were top-notch, courteous, and they answered all my questions. They explained the whole installation and running procedures for our new equipment. They also were well-aware of keeping our home clean during the process and after they were finished. A job WELL DONE! On another note, what is the warranty on this unit? I forgot to ask you during our initial contact. Once again, thanks.”

- Robert and Linda C.

Thank You for Saving the Day


“Dear Zed-Air Heating & Air Conditioning,


Thank you for saving the day! It seems that we had taken a central heating system for granted until we took late-season possession of a converted schoolhouse from 1865 with no heat but an open fireplace. We had researched five or six companies before we happened to stumble upon Zed-Air Heating & Air Conditioning, who agreed to put in a forced-air gas furnace in our unconventional dwelling.


Due to our small crawl space for the venting system and our loft on second storey, the heating installation job at our house posed some real challenges, as we did not want the original elements of the house disturbed. However, Richard from Zed-Air Heating & Air Conditioning worked successfully with our contractor, and they were able to complete the installation with hardly a change to the original house. We were thrilled, as no other company had even been willing to take on the job.


In fact, all the staff at Zed-Air Heating & Air Conditioning was fantastic from Richard, the foreman, who filled us with reassurance with his calm approach and problem-solving ability, to the installers, Jim, Brandon, Xavier and Mike. Even the secretary was extremely helpful in negotiating a change in hot water heater rental companies and giving useful tips. In fact, it was a pleasure having the team in our house, as they were always friendly, kept us up-to-date daily about the timeline and were clear in conveying information about the new heating system. Jim, who headed up the installation, and his assistant, Brandon, were particularly a pleasure while maintaining, at all times, a professional demeanor. Not only do we have the utmost respect for their expertise, but we also grew to become fond of them and truly felt that if our own sons turned out like these two young men, we would be proud.


Once again, thanks to Zed-Air Heating & Air Conditioning for taking on the impossible with a job refused by every other company in the area and completed in a timely fashion with excellent results and at a reasonable price point. We honestly feel that Zed-Air Heating & Air Conditioning performed a small miracle and truly saved the day bringing us our new forced-air gas furnace before the snow! We are thrilled and would recommend Zed-Air Heating & Air Conditioning to any customer looking for top-quality workmanship.”
