All of the staff are very honest, trustworthy, and reliable. Daryl, Richard and Alex are all great technicians that will make sure the job is done right. Their supporting staff and owners are awesome too. You will not be disappointed if you use this company!

I would highly recommend Sullivan! They were professional, courteous and competitively priced. Daryl and John Mark were great communicators kind to my children and easy to have at my house for the install! Great locally owned company will be using for years to come.

Mr. Richard and his staff were amazing to work with! They are professional, hard working, polite, friendly, and no nonsense! Can’t recommend them enough.

They did a great job friendly fast and very hard working thank you JOHN MARTIN

I was very happy with the service: they showed up the same day I called and were able to see the problem quickly and provide a speedy solution. Plus the technician, Daryl Fox, was both personable and professional. Altogether a pleasant experience!

Daryl was on time and very knowledgeable about my unit.

Great experience! The techs were very knowledgeable and honestly we didn’t even know they were there, they kept so quiet and did the job. And, I will give Koodos to Shad who came out twice and gave us an awesome price for the job- replacing our upstairs dead air conditioner. David and Daryl did a great job! Again, their price was so much better than other quotes we got for this. Recommend 100%

Sullivan has always been honest and forthright with us. We have a very old furnace and they still say it is in good condition and doesnt need to be replaced. Alex came to do maintenance on both of our furnaces and did a great job.

I have used Sullivan Services for a number of years. I have always been very pleased with any type of service provided. This past service, i.e., annual furnace maintenance, was no exception. Alex was very amicable, knowledgeable, and professional. He is definitely an asset to Sullivan Services. I shall definitely plan to continue using Sullivan Services for all of my heating and air-conditioning needs.

Friendly, professional service. The technician was very thorough, explaining all the results of the furnace test. He took the time to answer all of our questions, also. Highly recommend Sullivan!

We have used Sullivan for years and have always had great service. We have gotten same day or next day service several times because of the service plan. I highly recommend Sullivan Service.

They are on time, knowledgeable, and have fair prices! Their customer service is excellent! The technician, Alex, was very friendly and made me feel like family! I highly recommend this company!

Tech came out and let the freon out of my system and informed me I needed a new unit.... Now I need a new unit because my existing A/C is out of service.

Daryl was very knowledgeable, skillful and professional. He repaired my AC in a very efficient manner. I hope he is the one who comes for my winter check-up.

I was disappointed when the tech didnt show up on time. After getting that straight Alex told me what I needed and he came a d replaced my thermostats a d showed my son and I how to operate it. We shared testimonies about the Lord while never missing aa beat working. Hes very knowledgeable a bout what he does. The most important thing is they righted the wrong about the time and I was happy. Bless you Alex on your Christian journey. Walk in your healing knowing God is Healer. Be Blessed!!!

I was so happy with this company and service tech Alex i couldnt help but leave an outstanding review my air had gone out and my house upstairs was had gotten up to 113 degrees i called this company and they had someone out the next day to look at my unit and they said it had several leaks in it. Alex was very thorough in going over everything with me and all the details and how the process would work in replacing my unit. they came back the next day and installed my unit i couldnt be more happy with this company and my service tech Alex

Tech had an exceptionally high level of technical knowledge and skill. Resolved the issue efficiently and communicated the problem and solution very well. Highly recommend!

Alex is a great technician. Company should proactively contact customers for their annual system check ups.

The service techs and office personnel are very knowledgeable and treat you like family they dont try to sell you something you dont need.

Used these gone folks for years. Cannot recommend highly enough. Alex was super.

Please do not use this company they will lie to their customers about a.c. and heating unit to sell new ones. Abuse some of employees. Claim people are doing side work they not doing!
