Sunn Corporation

This company is the worse. They NEVER answer their phone. A company that is suppose to handle issues ²⁴⁄₇ never are available. It goes to a voicemail then says the mailbox is full. The do not return phone calls and just have overall bad customer service. Run don’t walk away from this business. Terrible!

I can’t tell you how frustrated I am with this company. We have been without heat for a week now and they can’t get to us for another week, even though their website says that they have 24 hour emergency service. I have a sick kid at home and she’s shivering from the cold. They actually were holding an appointment for me and I called and left 2 messages to confirm, but they told me that they never got them and gave my appointment away. Now they can’t fit us in for a week. We can’t afford to stay in a hotel for that long and space heaters aren’t cutting it and we can’t buy more. If I go with another company, I will lose my deposit on the service that was performed to determine the problem, and it will probably take just as long for another company to order parts. 2 weeks of no heat — just in time for the holidays. Thank you Sunn.

We have used Sunn Corp for years as has my dad. Very professional, prompt service, knowledgable techs. We would recommend them highly!

Very good not great, but kept at it to get it working. The repair took way too long, multiple parts multiple failures. Not certain if Sunn was responsible for some of the delay. I’m not an AC expert. They kept it and made it work. They seem like they were willing to go the extra mile and that goes along way. They seem honest and trustworthy. Crew in house was professional. Repair authorized by AHS. Would use again.

Excellent company! I was referred to Sunn Corp by AHS and am very happy with this company. I spoke with the owner, Karen, who is very knowledgeable in this industry. I contacted 2 other companies before making my choice; not only did Sunn Corp give me a great deal for an entire new system, but the service from the techs, receptionists and owner were AMAZING! I work with small to medium sized businesses every day and am impressed with how this company operates. No wonder Sunn Corp is very successful! I had my new unit installed a few days ago and already have referred them out to friends and family.

EXCELLENT, KNOWLEDGEABLE and FRIENDLY service from Daniel, Todd and Lindy of Sunn Corporation. After having rely on Emergency Heat for a few days due to a malfunctioned Defrost Control Board & Sensor on the outdoor heat pump system, the Team at Sunn Corp expertly diagnosed the problem, ordered the associated parts and came back out to fix the issue. Thanks Sunn Corp!!!

I really wanted to be a happy customer, but here I am on what forecasters say is the coldest day of the year, and I have no working furnace!
Sunn came to work to both units (and both were working, just not working at optimum).
They sent out their senior tech (aka McGuyver) and he tuned my furnace earlier today — a furnace that has worked without issue since 2004. But when I came home tonight, it was not working and nothing I did could get it working again. Calls to Sunn went unanswered, even to their emergency line.
I’m not happy, and as a result of this experience, can no longer recommend them. I hope I hear back from them tomorrow.

I have American home shield warranty for lat 15 years, and have always done yearly preventive maintenance service by AHS through Sunn Corporation, on Feb 2,2015 my heat pump stopped working, AHS assigned Pride Air Conditioning and Heating Services Co., INC of Manassas VA for diagnose and repairs, Pride heating and air conditioning representative spending hardly 5 minutes, submitted wrong information to AHS to make me do the repairs by paying $ 1020 from my pocket by saying «negligence in maintenance» by witch AHS denied my claim. Since my preventive maintenance was done by AHS on March 20, 2014 by Sunn corporation (less then a year ago and passed) I requested second opinion done by SUNN Corporation of Damascus MD, on Feb 3^rd SUNN corporation proved Prid’s report totally wrong by AHS paying all the expenses on Feb 3, 2015.
Thank you Todd and Sunn Corporation for your excellent and fair service.
I strongly suggest and recommend Sunn Corporation, wish I could give them more than 5 stars.

My gas furnace stopped heating last night so I called American Home Shield to get it repaired. This morning I was informed that Sunn Corp was going to come out but since it was Friday, I would be scheduled for Monday. I called Sunn to see if they could come out sooner since we have my elderly mother-​in-​law living with us and they fit us in! Today! I can’t thank them enough. We would have had to take my MIL somewhere for the weekend to keep her warm and that would be very hard with her medical condition. The technician had the problem fixed in no time and also took the time to give advice on a humidifier. This is the second time they have come to my house to fix my furnace in two years and both experiences were five-​star. Highly recommend Sunn Corp.

AVOID THIS COMPANY FOR YOUR HVAC REPAIRS!!! Horrible experience and very unprofessional
I was assigned to Sunn through AHS. The technician came out and diagnosed the problem promptly on a Thursday afternoon, as a cracked heat exchanger. I was told by the technician that the office manager of Sunn would call me later that evening to discuss the status of the repair claim and the timing of the next appointment.
After not receiving a call by the following Monday, I called Sunn asking to have someone call me and explain the extent of the repair and the timing of their expected return. I also called AHS asking them the same. AHS called Sunn (with me on the line) and faced similar issues with not being able to speak with someone. The AHS representative told me that they would continue to seek information from Sunn and they directed me to keep contacting them too. I continued to call Tuesday, Wednesday, Thursday, and Friday… still the same, no response.
Because my calls were not being returned, and the temperatures were dropping into the 30s, I called again and asked that I be placed on hold until I could speak live with someone. This was clearly not well received because after holding for a little bit the office manager, agitated by my request to speak with her, told me that they hadn’t even ordering the parts yet and that I needed to talk to AHS.
I am confused by this situation as my problem is clear, the replacement parts were fully covered by the Manufacturer (Trane) and all I need is someone to order the parts and install them.
I would NOT recommend this company to anyone.

Sunn is always my company of choice when I use AHS. Lindy and Karen who take the calls are always courteous and knowledgeable. The technicians are also courteous and professional and make a good effort to keep the place clean, and clean up should it be necessary. Nothing too exciting to write about other than they always do a good job and are dependable. That’s what’s important.

Terrible experience with 2 visits — within 3 weeks’ time — from this company through AHS. How bad? Second time the kid came out (I mean, why send someone more experienced the second time, right?) the make of our unit wasn’t even recorded correctly on the invoice! He wrote that a Pepco box was blocking the condenser, that nothing else was wrong, and it broke again within 12 hours. Much better experience with United last summer, with Jason who worked with AHS to get all of the repairs necessary at as little cost to us as possible. Unit worked wonderfully the rest of the season. Max Air on their way out this afternoon — we’ll see what happens!

When our AC went out a few months ago I contacted my home warranty company American Home Shield, and they dispatched for Sunn Corp to come take a look at our unit. It wasn’t a surprise when we were told that our unit needed to be replaced. Sunn Corp provided us with the exact cost to replace our A/​C and turn a around time for scheduling. When we were finally ready to schedule, the next available day wasn’t until a week later. Which was ok, because we were aware of the turn around time prior to scheduling. After a few days in the unbearable heat that took over our house I contacted Sun Corp to see if at any way possible we could get a earlier appointment because today was going to be another 90 degree day. The very professional and friendly lady that answered the phone said she couldn’t make any promises but she would see what she could do, and call me in a few. Later that morning I got a call that they squeezed us in and technician would be out in a hour. The technicians were in and out in less than two hours. I cannot thank Sunn Corp enough for fitting us in three days ahead of schedule and understanding we were in desperate need of a air conditioned house.

The other company AHS sent us, United Air Temp, refused to fix our problem and cancel our service without telling us. AHS has sent us to SUNN Corporation. They completely understood our frustration and bringing someone out first thing in the morning to fix our problem.
In the past, I called AHS for my fan in my furance that broke and they sent Sunn Corporation out on a Sunday in the middle of the winter and they fixed it within 2 hours. Very helpful company!
