Hi Jodie and Evan,

Just a short note to let you both know that it was a pleasure to deal with both of you cncerning the replacement of our Lifebreath HRV.. 

Most of the time Management only gets calls of complaints but I want to assure you both that i was very impressed with both of your personal and business approach to our purchase.

Thank you for restoring my belief that there are still companies who believe in Customer service .

Thank you both for your time.

As well I was quite impressed with the two service reps who came to nstall the unit. Kudos to them both.

Hi Jodie,

We want to let you know that all went well yesterday. Your installers were very professional and thorough, and a pleasure to deal with. We really appreciated the careful explanation they gave of our new furnace, thermostat, humidifier and hot water tank. Please let them know!

Also, thanks again for your help getting the Reliance HWT rental off our hands.

Thanks and cheers,

Gillian Sullivan and Chuck O’Dale at 382 Statewood

We’re very pleased with how the installation process went yesterday. Instead of simply doing a ‘satisfactory’ installation they took the time and care required to perform an ‘outstanding’ installation. It’s refreshing to see such high quality workmanship and attention to detail. They obviously take pride in their work and this reflects well on your company.

Thanks Evan, for your efforts in our decision and purchasing process. The wealth of information that you provided and your quick responses to my questions in emails were much appreciated.

We would like to get a cover for the air conditioner. Can you please let me know about price and availability?

Thursday evening my furnace was red tagged.  I called Capital City Heating and Cooling who responded immediately.  The technician confirmed the red tag.  The installers were at my house on Friday at 8:30 a.m. installing my new furnace.  They were friendly, polite and professional.  I would definitely recommend Capital City Heating & Cooling. 10 ++

I thought I would leave a review on your web site, but don’t see a spot to do so.

My air conditioner failed during the hot spell this week and I phoned on Thursday morning. I found your receptionist to be very helpful, and she indicated that she would be sure that someone came out the same day. I had a couple of other appointments to work around, and Kerry had to call back a couple of times to try to find a convenient time. I was very happy to be kept informed and with the flexibility shown. Ultimately, the appointment had to be scheduled for “after 5”. When it was getting close to 6 p.m. I was sure I was out of luck, but I received a phone call informing me that Alec would be there before 7. He arrived as indicated, and was able to diagnose the problem and provide me with an estimate, noting that my older air conditioner was reaching the end of its life. I chose to have him repair the air conditioner which he did very efficiently, and for the price indicated.

In summary, I was very pleased with all aspects of the service that I received, and would highly recommend Capital City.

Thank you for your most excellent service in replacing my old furnace and air conditioner last week. First your sales rep, Even, evaluated my requirements and explained my options in a concise and professional manner. Capital City was fast in securing the right equipment and arranging an acceptable installation date.

I was exceptionally impressed with your installation team Shawn, Taylor, and Tyson who worked together in a very efficient and pleasant manner. Their good natured banter while they worked made the job go smoothly.

The bottom line I am very satisfied with the installation.
I rate this experience 5 stars. Thank you.

I like to provide some feedback on an installation of a new furnace done this week. I had the good luck and pleasure to meet Shawn and Rusty. Two “keepers”.
I had all my preinstall questions answered and they provided me additional information on what was going to happen. It turns out my floor is significantly tilted towards the floor drain. This was probably a contributor to my other unit’s failure. The guys took the time to shim and align the new furnace. They also checked the AC unit and made sure it was correctly aligned.
After the install they took time to make sure that I was familiar with the new plumbing and operation. I was told that the furnace and AC where matched to provide most effective operation. All the new tubing and wiring was neat and secured in place. They left the work area cleaner than they found it!
Thanks for providing great service.
