I have a had the pleasure of having Comfort Specialists take care of my furnace and air conditioning since 2010. I pay for the additional maintenance every year. It is worth it in every way. I love my air, furnace, humidifier and my whole house fan! Thank-you Comfort Specialist. T Bachman

Very good customer service! Spoke to them today regarding getting a quote and they were extremely professional, explained the trip charge / diagnostic fees, and communicated that a manager would be in touch soon. Although I have not yet had work done by these folks, they did come highly recommended - I was told they do excellent work, are always reachable, and Mark (the owner) is a true professional.

Our furnace and a/c were not giving us a problem but opted to get new ones because ours were 24 years old. We got different quotes from different companies and different brands. We decided to go with the Trane because that is what we had and they had worked fine. Mark and Jonathan came and took the old one out and new one in in about 7 hours. We hardly knew they were here. Both were professional and nice. Haven't had to use the air yet but am happy with the furnace so far. It is quieter and keeps the temperature more even throughout the day. Thanks Mark and Jonathon.

I had the pleasure of going with Comfort Specialists, Inc. specifically Mark Sellner, he was very thorough and what I consider customer friendly, he gave me a great estimate and I had my furnace, C. A. unit, and duct work, replaced, including an old flue pipe that needed replaced. Thank you again Mark, really appreciate your professionalism. James

Frequently Asked Questions

How does Comfort Specialists price repairs?

It charges by the job rather than by the hour. The diagnostic charge covers the trip and time needed to identify the problem, and the repair price is provided for approval before work begins.

How long does a new system installation take?

A furnace installation commonly takes one day; installing a furnace and air conditioner commonly takes a day and a half. New system installations also include airflow balancing.

Is emergency service available after hours?

Emergency service is available after hours on weekdays, weekends and holidays. An on-call technician can answer questions and try to get the system running until a service call can be scheduled during normal working hours.

What equipment does Comfort Specialists not service?

It does not service hot water boilers, window or automotive air-conditioning units, or geothermal heat pumps.

What guarantee applies to heating and cooling repairs?

The company says its heating and cooling repairs carry a one-year guarantee.
