Hi Walter 

First off, we appreciate that you stored the unit for us over the summer until it we had reasonable weather to do the exchange.  We also appreciated that you could get the removal and install done in a day.  Mark says the crew was very professional and were able to overcome the issues that arose over the course of the day.  All in all – positive experience.

Compliments to the two `Matts’ who replaced our electric furnace and heat pump this week.

They explained the work plan along the way and patiently answered our questions. At the  end of the last day here they ensured we were familiar with some specifics of the installation and the operation of the replacement thermostat and so on.

They demonstrated professionalism, and were courteous and diligent.

In our view they are fine representatives of your company indeed.

I just want to tell you how pleased I have been with Andrew that has been working very hard to eliminate a very disturbing noise from our A/C units at 1335 Jefferson Avenue. He has spent a great deal of time trouble shooting, tightening and running up and down from the roof on a couple of occasions.

This noise was non stop directly above my desk. The last visit he needed to disconnect some power to the motor till parts could be found and explained everything he was about to do to be sure I would be ok with it. He found the problem and came up with a solution I have been very happy with, until parts can be replaced. He provided the best customer service I have had in a very long time. Please pass on my appreciation and know he should be recognized for his efforts.

Thank you so much for getting the job done in UCN! It was great working with you and the team on this project, and the end result is very good, the pressure tank and the backflow preventer are doing their job, and we can touch improvement on the loop.

Happy New Year Walter, Thank you and your staff for all the work they did to put in a new geo thermal unit in our house. What a pleasure it was to do business with a company that practices superior customer service. Once the work was completed, “Thomas” explained how everything worked and what to do if a problem occurred > Call him day or night! We have dealt with frontier for 20 some odd years and would recommend them to anyone.

The startup on Sat could not have gone any better which is a indication of the work your guys performed. (Also Walter and I did a  pretty good job on the engineering as well)

Hey Wally/Walter,

Pat gave great feedback on your repairs/customer care you provided at her residence last week.

Keep up the great work buddy !!!!


Thanks Walter, nice to hear from you. Your guys have been providing excellent service


Larry and Dave,
It is always good news when you do not receive calls after recent services.The freeze dryer has been working good for the last week, and yesterday we initiated another run. The unit, so far, is performing just fine. Thank you for your dedication, perseverance and knowledge.



Walter, We have had Geo-thermal for 20 years. The system is the closed loop. The first furnace was installed and then replaced with a second unit which has now been in for 12 years and we have had no problems. Frontier has looked after us with great service.  The heating system is great and very efficient.  We are very pleased with the company. Thanks.

Walter & Walter Jr.: I want to thank you both for the fast service in diagnosing the problem with my heat pump.  Then Walter finding me a new fan motor.  Then the work that Walter Jr. did with the installation, modification in the fan motor logic.  The job was done as quickly as possible and the work site was left clean. Thank you

“We had an hvac unit installed in our church building and I can say that Walter and the team at frontier are very professional. Frontier went out of their way for us and made this experience a great one! They are friendly, knowledgeable and honest about what they do. You will definitely be making the right choice by using frontier refrigeration and mechanical systems!”

Ken F. – Today’s Church

German dedication and quality of workmanship. I like that.

Wanted to say a HUGE Thank you to your company, Frontier Refrigeration & Mechanical Services. In January our Fan Motor on our Geothermal Furnace failed and we called a competitor to come and fix the issue. We were left a week and a half without heat during the coldest time of the year (-45c at its coldest), multiple dangerous ongoing wiring & mechanical issues, unnecessary part replacement and a huge bill!

We were at the end of our rope and discouraged.

Two months into the process our hot water tank needed replacing and knew the right thing to do was call Frontier to replace the hot water tank and take a look at the Geothermal furnace to see if your team could diagnose and fix the issues the competitor had caused.

Your team was not only professional, clean and courteous while replacing the hot water tank, but managed to diagnose the furnace issues quickly as well. Your guys saved us from cold nights and likely saved us from having our house burning down due to bad wiring on the electrical panel. We can’t thank you all enough! You should be very proud of your team and the quality of service you provide! I would recommend you guys in a heartbeat and advise anyone to wait until your team can get there before calling anyone else!

I would highly recommend Frontier Mechanical for any work that might need to be done.  The quality of the product and their staff has been outstanding.   About 20 years ago I had them put a ground source heating system when I built my home.   In that entire time I had no problems with my system.   It is also attached to my main hot water tank and we never ran out of hot water while raising three sons and all that was needed to keep them clean.  We just had an issue with the furnace after all this time.   I called Frontier about it and they were here the next day  ( I couldn’t be home the day I called )

The service man ( Wally )  Was quick and we are very happy that our system is now fully working.  THANK YOU ALL AT Frontier for your service.  

I would recommend them to anyone.

John P.

Walter it is us who should be thanking you for your patience, and the hard work you completed to make the customer happy. Thank you.

Ron V. – Rheem Canada Ltd  

We have used Frontier Mechanical on two separate occasions for commercial and residential. Dealing with Walter was a pleasure, when he quoted on the commercial refrigeration he came with many options and price points. When we decided to go with Frontier for the HVAC for the cooler, the job was done on time and on budget. I then decided to use Frontier again for a residential job on my house. The job was a difficult retrofit and they were very flexible on listening to my opinions as to hide the new piping. I would use Frontier again and would not hesitate to recommend the company to anyone.

Jonathon G.,  – CEO

Hi Walter, I was just at my Springfield location and everything looked good. Your guys did an excellent job! Thanks.

Greg W. – IT Manager STAR

The Ice machine is running well –  the installation and service were great! It was a pleasure to meet Wally and Steve. Thanks Walter.

Molly P. – UOM Biochemistry

Just to quickly touch base with you to let you know that the job that Rick and Scott completed on our water chiller system is working perfectly.
In a very professional way they searched for the problem, found the solution and we did not have any issues since then. Thanks.

Isaac C., P.Eng

Walter, I have attached the Oct 15 and Jan 16 data of our new Ecosmart Geosmart GT that was installed last March, as you can see the performance has made me extremely happy. The efficiency and operation of the heat pump seems to be well above our old Cantherm that was removed, we keep the house temperature 1 degree C warmer (I don’t move the set temp at all set at 22 C) our auxiliary base board heaters in the sun room very seldom come on (Dimplex LRC with wall mount thermostat set at 20C).

“Thanks for your service. You are proud of your son and staff for good reason. I am glad that Sharon recommended you.”

Gentlemen, Please consider adding Frontier Mechanical to our list of pre-qualified mechanical contractors. Walter Lehman is a locally recognized refrigeration expert. We call Walter for advice whenever we have a problem that we cannot solve. I am confident that his new company will provide us with excellent service! Thanks for your consideration.”-Mike, University of Manitoba-“Hi Walter, I’m writing this to inform you and the guys that did the install how pleased I am with your work and the performance of my new updated heat pump (GEOSMART ) at my home. The performance compared to the old heat pump is beyond my expectations, the operating time and power consumption is at least 30-40% less than the old system which I thought was good. I’m anxious to see how the system performs in the dead of a Winnipeg winter, judging up to now (March to date) it should also exceed my expectations.I must also add I am very pleased with quietness of the operation compared to my old Cantherm system. I’ll keep you informed as our winter progresses. Thanks again.”



“Well, I was freezing my butt off in there the other day! Our Tree Freezer seems to work fine, thanks for the good work.”

Dave – Pineland Forest Nursery

 “Frontier definitely has the best crew. All their guys are very knowledgable and friendly. Mostly important, they know what they are doing. They fix everything right at the first time. Furthermore, they understand the urgency of the fast food industry very well, they do everything possible to eliminate/minimize my downtime. Highly recommended to any restaurants or anyone who need cooling o/a heating services.”

Tim – DQ

“Hi Steve, everything is working 100% I have not touched anything at all with any part of the system . I think that because everything is working so well, management has forgotten there’s still work to be done! But I have sent in the request have more t-stats to be replaced and the hrv s to be placed on timers. Still waiting for new budget. I have to say , that asking for more to be done is hard when this is the best that the heat has worked in the 7 years , I highly recommend frontier mechanical to anybody. We will be in touch as soon as I get the green light.”


Glenn – O&M Nnec Siouxlookout

“Over the past 5 years we’ve worked closely with Frontier Refrigeration on numerous mechanical projects including steam boiler retrofitting, installation of new condensing boiler hot water heating and geothermal cooling systems, and maintenance of our existing mechanical refrigeration systems. Working with Walter and the crews from Frontier has always been professional, flexible, and straightforward even when challenges arise. I would certainly recommend them for any HVAC project.”


Peregrin, P.Eng. Project Manager / Building Partner SO-X Building

“I have confidence in you Walter. A company is just a company. I did just that, built a company around good people. Thanks for your help.”

Brian – COO Entegra

“Frontier Refrigeration removed our geothermal heat pump and installed the new heat pump and thermostat over the last couple of days. They did a fantastic job!”
