The technician that arrived was VERY professional and RESPONSIVE to our needs. Our A/C had frozen up and stopped working. He diagnosed the problem and corrected it. During his first visit he discovered a part was not installed at the time of construction, he also at this time checked to make sure the drain lines flowed correctly. He ordered the missing part and on his second visit installed the part and again checked that everything was working correctly. With the quality of service I will be keeping Long's phone number handy.

Home AC went out over Memorial Day holiday. Contacted Long Heating and Air. Office staff was pleasant and helpful! Kyle, the Technician, arrived even before appointment, was professional and personable. Walked me through possibilities. Called in to check prices with Jason, who was also professional and personable. Jason kept me up to speed with order of unit and earliest possible install date. I found along Heating and Air to be great to work with and I recommend then to meet your AC / Heating needs.

Long came to my house to diagnose an AC problem. The tech told me I needed a new fan which is located in the furnace. He gave me a quote on the fan replacement and a quote to replace the entire furnace. He told me to contact the office with any questions. I had several questions and called the number on the website and asked to speak to the person the tech referred me to. No answer and his voicemail was a different person.

I called back, explained what I needed and was sent to another number for the same person. Again no answer and the voicemail was a different person. This happened four times until I was told the man I was calling was in meetings all day and to leave a message on the voicemail I was connected to, which I did. That was on Friday, May 20. Today is Friday, May 27 and I still have not been contacted. I assumed earlier in the week that they did not want my business so I had the furnace replaced by a different business. I'm giving them two stars because the tech was good, on time, and helpful. It was the rest of the staff who dropped the ball.

We had Long Heating & Air come out as part of warranty service call for our A/C unit. Technician was great! Extremely thorough - found the issue quickly but continued to check everything else to make sure it was all in good order. Respectful, friendly, and gave some good tips/recommendations. Highly recommend! Service: A/C system repair

First of all, this unit had a new coil put in in December (only 3 years old) and Long was very helpful in getting that done. Of course, the air hadn't been needed since, but was turned on this past weekend, and did not work. Angel came out the day after I called and was great. He found the new problem (more leaks) and explained in detail what he did to fix them. He also explained that the fix might not hold if the part itself is bad (time will tell) and was proactive in calling his boss to see what they could do for me, should that occur. Good people!

Our house got struck by lightning and fried the compositor and a fuse. Technician came out, quickly figured out the issue, fix it and restore the heat. He also recommended a surge protector to help us not have this issue again in the future! He was kind and professional. I am very happy and warm again.

Long previously performed service on my furnace which required the large duct to be removed from the furnace. The duct was reattached, but over time the duct connection came apart. I called Long and they repaired the connection quickly(the next day) after my call. The service tech was knowledgeable, very professional and finished the job quickly. I was very satisfied.
