  • Some time ago we selected Capital City to install a new air conditioner during a heat wave.It was a positive experience, good price, service and quality work. When our old furnace quit on the coldest day of the year, 2 years ago, Jodi and Alex found a new fan and had it installed within a few hours.... Read More
  • I came home on the evening of November 21 to no heat. Called Capital City on Monday morning. They attended promptly Monday, conducted a thorough inspection, red tagged my failed furnace (old, it deserved its retirement), and sent their estimator. By Tuesday evening our brand new Bryant furnace, and ... Read More
  • What a great company. Your installation employees were professional, courteous, honest and knowledgeable. The installation took 11 hours and not once did they complain that they were tired. They had to dismantle the old 50 year old Dinosaur that surprisingly still functioned but was condemned becaus... Read More

  • We had a great experience with Capital City! Evan provided a detailed explanation of our options and ensured our new air conditioner was install very quickly. We are very happy with our product and service provided by Capital City.

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.

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.
