At Yost and Campbell Heating / Air Conditioning / Generators are only part of our business, the other and most important part, our customers. We pledge to our customers that we will continue providing the service that our founders Leo Yost and Alvin Campbell envisioned for their clients in 1939. Below is a small list of what our satisfied customers are saying.

My experience was not great, it was amazing!!! Beyond 5 star service. I had my ac system serviced by your technician Jared, who I believe to be an incredible asset to your company. This is the second time Jared has been to my house to assist and he never fails to be the perfect gentleman aside from someone so knowledgeable in their craft with a brilliant work ethic. I smiled from ear to ear when my wife and heard the knock on the door and saw Jared was our technician. He remembered our names and even our dog (who adored him too). He expediently and knowledgeably performed his duties. He even inquired as to how our system ran last summer after his repairs were performed. The whole time he was patient with my questions. I am so fortunate for the opportunity to have met and chatted with him again while he broke his rear end working to cross every t and dot every I. Please commend Jared Davis as an amazing employee and human being who deserves so much recognition and praise. Thank you so very much.

Dan is the technician who corrected the problem with my A/C today. Not only did he quickly resolve the issue but he was VERY informative and personable. He was patient in answering some questions and did not give me the "rush treatment" because he had to service another customer. I will be calling Y&C for all my heating and A/C needs and will certainly request Dan if he's available.

Tom and Everyone at Yost and Campbell,
While this winter has made it difficult to assess the efficiency of our newES25, it has been an absolute delight in terms of operating characteristics, including quietness. Also the White Rogers thermostats are a significant upgrade to the Honeywells they replaced. All in all I am delighted with the Burnham boiler and the Superstor Ultra water heater. Best proof all was the knowledgeable and well trained staff of Yost and Campbell who put it all together. A wonderful experience.


…our house (and the entire block) lost power this morning but our generator that you installed kicked in and worked perfectly! Thanks for the great install!


We have been so happy with our heating, AC, and hot water heater you installed for us.
Thank You,


Guys at Y&C,
I just wanted to express my appreciation for Yost getting us through the storm. In very difficult conditions you guys came through for our generator and our furnace. Thanks to Annmarie, Chris, and Jose.


You have an amazing service department. In the recent storm, a large tree limb broke off from a neighbor’s tree and landed on our deck and right on and next to the generator. Dave came out right away and turned off the generator for safety reasons because he was not able to confirm that the generator was in proper operating condition. We do know that the Generac case was significantly dam…aged and will need to be replaced, but hopefully the case did its job and protected the motor and interior gas and electrical connections. Bryan will be coming out today to examine the unit now that the branch has been removed this morning. Thank you for providing such excellent service.


Dear Tom,
Thank you very much for coming to our house so late last night to go over everything. We really appreciated it. It has been a pleasure dealing with you during this entire process.


Yost & Campbell,
My husband and I would like to thank you for sending a repairman this morning. As expected, he did a splendid job to replace our old thermostat and checked the furnace. It now works like a magic. The repairman was very thorough, professional, pleasant and polite. (I think he is cool because he knows how to use the iPad!) Thank you again for your prompt response and service,


To everyone @ YOST & CAMPBELL,My brother and I wanted to thank everyone, including the owner, gm, office workers and field technicians, for the quick and professional way you handled our recent severe boiler problems. It’s nice to know that in today “business comes first mentality”, a company like yours still believes in customer service and loyalty. We are truly thankful and look forward to doing business with you in the future. Needless to say we have STRONGLY recommended your company to many of our friends and neighbors. Thanks again,

One a freezing cold later winter morning the hot water furnace stopped burning. So around 10am I started making calls all over the names on this site asking for price and when someone would be able to come by. Everyone else gave me appt for the next day, which was almost impossible as we couldn’t stay without heating overnight. Y&C was right on. I told them the situation and the person that I spoke with told me that they’ll stop by the same day, no matter what. She couldn’t tell me what time the technician would come by, but he will be at our house the same day. I was worried since they didn’t give me the time, but someone did show up and they fixed the furnace when we needed most.

Wow! The service, communication, and professionalism I experienced from Yost and Campbell from start to finish completely exceeded my expectations. The lady I spoke to on the phone was friendly and scheduled me an appointment very quickly. The technician was on time, professional, and very knowledgeable. The work was done in a timely and efficient manner, and everything works great! I am so pleased with this experience, and will definitely recommend Yost to my family and friends. I will be sure to use them again!

We feel very confident with Yost & Campbell after todays first experience with them. Dave came over to check the boiler and told us the sounds were normal expansion and contraction sounds. There was no backdraft detected and no rust. He pointed out a tiny leak and advised us to keep an eye on it. We are good to go with our 30 year old boiler. Thank you David and Yost & Campbell!

Marilyn and I would like to express our delight with all involved at Y&C for a great job today on our replacement Water Heater. Coming home from Florida yesterday with a broken tank was a real concern. Thank to Ann Marie for the early morning call and for settingup the appropriate arrangements. Thanks to Aaron for a most professional job and to Greg for the assist. Please pass this along to the "big guy".

I would like to thank the tech who came to my house today. He replaced the gas valve and after it ran a bit tightened the pilot sensor as it had become lose. I wuld have been very easy for him to tell me that I needed a new one, but he said that it just needed to be cleaned and tightened up. I appreciate his honesty, that is why I have been a contract customer for so many years.

Dave is beyond profesional, and so nice and neat. Just wanted to let you know how pleased we are with the quality of your work!

I've used Yost and Campbell before to replace my A/C and furnace. They are a professional organization and their staff is always very willing to help and very patient with explaining everything. They just replaced my Hot Water Heater and I'm so far very pleased with the service.

ER Westchester NY 

When I bought my house 10 years ago, 2 rooms were not getting warm enough heat in the winter because they only had radiant heat. I called multiple companies to solve the problem, but Yost and Campbell was the one that came up with a solution. I've been using them ever since to service my boiler and air conditioning. I have found them to be well-priced, courteous and punctual, even on the coldest winter days.

RE Dobbs Ferry NY

I have used Yost and Campbell in the past and have always been happy with their work.  Yesterday the baseboard heating in my den, which is a separate burner from the house, stopped working.  I called Y&C no Monday and Noel was here Tues at 9am.  Noel was very thorough, explained the valve that was not working and replaced the part at a fair price.  I recommend Yost and Campbell and will use them the next time I have a plumbing or heating issue.

PB White Plains NY

My gas service was locked by Con Ed because of a leak on Saturday night. Yost and Campbell responded immediately (on a Sunday), diagnosed the problem, repaired it quickly and efficiently, and got my service restored in record time rescuing me from freezing pipes and thousands of dollars in property damage. Highly recommended!!!!!!
