Yost & Campbell Heating, Cooling & Generators In 1939, Leo Yost and Alvin Campbell started a humble refrigerator repair service in Yost's garage. They started with a simple principle: provide quality service in a timely fashion without charging more than the customer could afford. The formula worked, as such formulas often do, and Yost & Campbell Heating, Cooling & Generators was soon on the map.

It's 75 years later, and we're still here: providing quality HVAC, generator, and water heater services throughout the tri-state area. The game may have changed and we're certainly servicing a large number of additional systems and products, but our core goals haven't changed.
Services
At Yost & Campbell Heating, Cooling & Generators we're proud to have been a part of life here in Westchester County for over 80 years. It started back in 1939, when two partners-Leo Yost and Alvin Campbell-began a refrigerator repair business out of Yost's garage. Our business grew from there until it covered all aspects of heating, cooling, plumbing, and indoor air quality, and served homes and businesses throughout Westchester County, The Bronx, Queens, and Rockland.Today, our business continues adhering to the traditions our founders believed in: providing quality service in a timely fashion without charging our customers an arm and a leg.
They're dedicated to making sure your heating, air conditioning and generator equipment is running at peak efficiency so that you feel comfortable in your home. In the 1960's, Tom Monahan, Sr. purchased Yost & Campbell from Leo Yost, which gave his son Tom Jr. the opportunity to work for the company throughout high school and college.

I had a boiler problem where my hot water would run cold after a few minutes, and two times someone came to look at it and could not figure it out. However, when Yost and Campbell sent Ricardo he was able to find the cause of the problem and order a transducer, which he said should show a steady red light when the boiler is calling for hot water. Ricardo was so unbelievably knowledgeable about my Baxi wall hung boiler, and he was extremely professional and polite as well. I can't say enough good things about the service he provided.

I had been meaning to write a review for Yost & Campbell but never got around to it. First off I want to say what great service and a group of people this company has. I take care of my mom's home while she is away for long periods of time and I know without a shadow of a doubt that I can turn to Yost & Campbell whenever there is an issue with my mom's house.

I will say they are not cheap but worth every penny. They don't try to up - sell you services- they tell they what services they offer and if you wish to sign- up, you can. I love Yost and Campbell and recommend them to everyone I can.

Avoid at all costs. I was looking to have an evaluation/cost estimate for central air installation and a new boiler - probably a $35-40k job. First I scheduled an appointment online for a Saturday. Then they called and said that it was not actually available. So I scheduled an appointment for a Monday (two weeks later) and re-arranged my work schedule to compensate.

They then called me the Friday before saying that the date was no longer available. They were very unapologetic and didn't seem to care to miss out on a rather large job. Don't waste your time like I did.

We have dealt with Yost and Campbell for better than 20 years, since we purchase our house. In this instance, we decided to replace and update our heating and air conditioner system that was almost 20 years old and no longer working effectively. Y&C's staff, from sales representative, deliverers, installers and office staff were courteous, professional and responsive to our needs. They went over the installation and explained everything. We are confident that we are set with a solid product.

My experience with Yost & Campbell has been excellent. They have been professional, trustworthy and reliable. They installed a new furnace and hauled away my old one in a day. Y&C will be installing a new heat pump and thermostat when it comes in and I will certainly provide further feedback upon completion! Service: Heating system installation

My experience with the team from Yost & Campbell was exceptional under the circumstances. That is, requiring services within the peak HVAC installation and servicing period, post a major disaster where demand for HVAC services was in high demand along with supply chain issues. Our project manager Katherine was a pleasure to work with. She ensured all our questions and issues were addressed in a timely manner despite any hurdles we encountered along the way.

Special thanks to our installation manager Leo and his team for ensuring all technical questions were answered and the quality of work not compromised due to high demand and scheduling constraints.

The company notified me that it was time for maintenance. It's great not having to remember myself and scheduling was easy. The technician arrived on time. He was professional, friendly and very knowledgeable. He checked my furnace thoroughly, replaced the air filter and answered all of my questions. He checked my ductless system and gave me some important tips on maintenance. I'm extremely pleased with Yost and Campbell. So much better than Sears.

I got in contact with this company through Home Depot. My heating unit needed fixing so I scheduled an appointment. A technician came and I was told I needed to replace the motor to get the unit fixed. The cost was $842. Turns out, that wasn't the problem. I called the office the next day and spoke with a lady, her name was Rina who was going back and forth on the phone with me And told me that nobody gets trained for customer service and that her job was not to understand customers frustration.

She was so rude. I was telling her that even after changing the motor the problem was not fixed. Her answer, well, I have to give you another quote because it seems there is a problem with the switches. I said, you guys told me it was the motor and I paid over $800 for that. Now you are giving me a quote for switches? So what happens with the motor that was changed.

I said, I'm sure you can understand my frustration. After so much back and forth with her, she put another person on the phone, her name was Jackie. She told me they will put the old part back and refund the money. It took them over 2 weeks to refund my money after they put the old part back. Every time I called to inquire about the status of the refund I was met with animosity, attitude and it was really an awful experience. I couldn't believe the level of customer service. I do not recommend this company. It is unfortunate that Home Depot refers you to them for any HVAC inquiries.

I must say that Yost & Campbell did a phenomenal job with installing our heating/cooling system. The team worked diligently and was very courteous. After researching and comparing various companies, the pricing of the project with Yost & Campbell was very reasonable. My home now has great heating (My heat hasn't been this good since I moved in over 14 years ago). I don't do many reviews but I highly recommend Yost & Campbell. Great job!

Service Technician Sam Haddad is a professional. Listened to all my problems. Looked at the heating unit ( gas valve was cycling on and off )took his time to look over the entire system. Trouble shot the system and determined the thermostat was bad. He took me over and showed me how he determined the root cause. I replaced the thermostat and the system worked perfectly. You don't find people like this anymore. Thanks for your service. Job well done.

We couldn’t have been more pleased with our experience with Yost & Campbell installing the ductless units at our house. They were professional, courteous, prompt and efficient. Each tech was knowledgeable and respectful. One of techs even ended up finding an unrelated issue in our basement and offered advice. We would absolutely recommend them and would use them for future work at our house.

The current ConEd discount incentive was very helpful in reducing our out pocket of expense, since the rebate goes directly to Yost & Campbell. Very convenient to not have to worry about the hassle of going through ConEd directly.

I highly recommend Yost & Campbell, they are extremely conscientious and professional - They have kept me informed every step of the way with my installation. The technicians they sent to my home were respectful and considerate. I would say that Yost & Campbell exceeded my expectations, I am very happy that I chose them for my project.

I had my furnace replaced and this was my best experience EVER! I was honestly dreading this, but from the sales person to the technicians, they exemplified professionalism throughout the entire process and I could not be more pleased. Thank you!
