Your Satisfaction is Our Goal

A Sample of our Real Customer Reviews

"I had a query about a sound I heard with my furnace and David was SO friendly and SO kind! He walked me through a few things I could try and look into myself - learned some things I never knew! He also gave me great information about other products and services available. If you want to work with a great human, call David!"

Sandra McQueen

"I was having problems with the heater in my garage (It wasn't working!) and called on David. He came out within a few days, was on time, and did a great job. He not only fixed the problem but also identified a couple of others and suggested I call the appropriate services so as to prevent future damage to my garage/roof. He did a great job, went above and beyond, and was professional and helpful! I would definitely call on him again for future needs!"

Lorna Stuber

"I used David with Lancelot Furnace for a second on a few of my installs and have had great luck with his quality of work as well as his professional behavior. Would definitely use him again."

How Quickly Will You Be Here After I Book an Appointment?

We provide an accurate time estimate at the time of booking. If booking for a future date, we will confirm the appointment the day prior.

Why Do You Exclusively Install Bryant Air Conditioners?

Like a new furnace, an investment in a new air conditioner is not insignificant. Homeowners should feel good about the HVAC appliances we install.

We have installed literally hundreds of Bryant furnaces and AC’s and rarely have problems. We have found Bryant to be reliable, feature-rich relative to their price, and a good value. We feel good about installing Bryant air conditioners, and not just because we rarely have to honour the warranty 😉

What Types of Air Conditioners Can You Service?

We’re familiar with most of the makes and models of residential air conditioners found in Alberta. Having performed hundreds of repairs over the years, we’re familiar with how the environment affects air conditioners and are generally able to fix the problem pretty quickly.

What Are Your Warranties On Air Conditioner Repairs & New Air Conditioners That You Install?

We want you to feel good about choosing Lancelot Heating and Cooling, and so we protect your investment in us with warranties on parts and labour.

Air Conditioner Repairs

Not all AC repairs are performed equally! We use OEM or OEM-equivalent parts (where OEM isn’t possible for some reason) and provide a 1-year warranty on parts and labour. If our repair fails, we’ll be back to get it sorted at no-charge.

New Air Conditioner Installation

Your investment in a new air conditioner is backed by a 10-year parts and labour warranty. This is a smart addition to your home that you can depend on!

How Much Does it Cost to Run an Efficient Air Conditioner?

Modern air conditioners, such as the Bryant air conditioners that we install, are much more efficient than central air conditioners from 15 or more years ago.

There are many circumstances that influence both cooling performance and overall air conditioner efficiency, not to mention the price of electricity.

Considering the above, it is not unreasonable to expect an air conditioner to consume anywhere from $0.25/hr to $0.40/hr of electricity when it is running.
