Specialized solutions

Gordon R. Williams Corporation offers cost-effective specialized HVAC solutions for both retrofit and new construction. We have an extensive range of new and replacement HVAC products available for commercial, institutional and industrial buildings. Through our contractor customers, we offer homeowners leading technologies in home comfort conditioning, especially our line of air conditioners that can be installed in homes that don’t or can’t have forced air duct systems.

What do we look for in a climate conditioning product?


Above all, we believe people want clean, environmentally friendly, energy-efficient, good-looking equipment. We will not distribute a product if it does not meet these requirements. In addition, we believe that comfortable environments should be available, even where there are difficult conditions, such as older multi-unit buildings, buildings without duct work, and even open-air or temporary locations like movie shoots.


Not just equipment. We provide total project management and turnkey solutions, no matter how complex your requirements are. Our experienced team can provide project coordination, start-up analysis as well as service and maintenance plans.

Frequently asked questions

Do all new PTACs provide the same cost savings?

No, just because you purchase a new PTAC does not mean that it will save you money. Ask us about how a GE heat pump unit pays for itself and saves you money in future. Your ROI is extremely short meaning you will be keeping dollars in your pocket that much quicker. Imagine not paying your utility company large sums of operating expense dollars within such a short period of time. This is based on the efficiency of the GE unit in comparison to ALL other heat-pumps in the market place! PTAC efficiencies are all different. We challenge you to compare the facts that each manufacturer must document.

Do I need remote PTAC control using an on-the-wall thermostat?

No, but to ensure proper measurement of temperature within your living space it is highly recommended that an on the wall thermostat is used with all PTAC units. This will help the overall feel of temperature within your living space.

Do I need to clean my PTAC air filters?

Yes. Filters require a regular cleaning in order to maintain a high level of air quality and extend the life of the unit.

Do you ship internationally?

Gordon R. Williams Corporation is located just outside of Toronto, Ontario, Canada and ships within Canada only.

All orders containing in-stock items will ship from our location within 1-2 business days. Out of stock items can take 1-3 business weeks to ship from the item’s order date. Shipping via UPS, the order is guaranteed to arrive within 5-7 business days from the date it leaves our warehouse. Whether or not your item is in stock, you will be provided with a UPS tracking number once your order has shipped.

I need my order quickly. Do you offer next day shipping?

At this time, we only offer Standard UPS Shipping (5-7 business days) through our online store. If you need the order to ship/arrive on a specific date, please contact us to place the order with a representative. We will do our best to accommodate your requirements.

My tracking number indicates the order has been delivered but I have not received my item(s).

If your UPS tracking number indicates the parcel has been delivered but you’ve yet to receive anything, please check the following prior to contacting us:

1) It is highly possible that the driver has marked your package “delivered” prior to dropping it off at your location. Please wait until 8:00 PM of the day of delivery noted within the tracking information to determine if the package is still with the driver.

2) If applicable, check with other residents to make sure nobody else has accepted the parcel on your behalf.

3) If nobody was available to accept the delivery at the door, UPS may safe drop the order in a discreet location around your front door/porch. Please check around your front door, behind bushes, under porch furniture, etc.

4) If you have not received your order or a UPS notice card indicating where it can be picked up, please contact UPS and reference your tracking number to confirm whether or not the order is available for pick-up at a nearby depot.

What are the key elements in deciding which PTAC to purchase?

Everyone has their own specific reasons as to why one PTAC is best for you versus another, but we believe that the total cost of ownership for that unit includes elements that must be well thought out before you buy. Some of these issues that you must address include – the cost of repair post purchase, parts availability if you can even source parts easily or at all, serviceability of that unit, ability to tie that unit onto energy management solutions if that is something that you may be interested in doing in future. Above all – energy consumption, noise level and expected life span of that unit is what will provide you with ultimate content with your decision. A poor choice will provide you with years of regret. Just because the unit fits in the hole in the wall is not enough reason to go with the least priced unit.

What will happen to my order if I am not home at the time of delivery?

UPS will always first try to deliver the order to someone within the residence. If nobody is available to accept the package, UPS will leave a notice card indicating a nearby depot address where the order can be picked up. Hours of operation may vary depending on the depot location.
