 Trustindex verifies that the original source of the review is Google. Comfort Zone is awesome. I live out in Western Loudoun, they’ve serviced my units for over three years now. They’ve never tried to deadline equipment too early to make a sale, and they’ve always extended the life of my equipment, taking great care and understanding my budget.

I love that they took the time to understand my budget and what I could afford. So they did extend the life of a 17 year unit for me while I saved up the extra that I needed. And when they made a recommendation for repair and I told them I needed to save money, they worked on helping me save the money and did what they could until I could have the funds in place. Of course that was because my unit could be extended. Nice to not have someone push something on you to scare you into a unit earlier than you need when you’re right in money.

As for the service and the units, the quality has been great, the service has been awesome. The installers are knowledgeable and respectful of your home.

I would highly recommend them for any HVAC needs you may have.

 Trustindex verifies that the original source of the review is Google. I was dealing with another AC company at first because they were given to me by my product warranty company and they were completely incompetent. They took several weeks and were completely unhelpful in working with my warranty company. Sean, from Comfort, immediately asks for the information for my warranty company and within days my AC was installed. He was professional, timely with his responses, and installed my AC unit without a problem. I highly recommend working with him if you want reliable and valued service.
