HVAC reviews in Mt Vernon, New York

Eric did a great job on my boiler. He clearly knew what he was doing and took the time to explain everything. I'm really happy with the service, thanks Eric!

Service Tech Alex arrived on time, was polite and left the place cleaner than when he started. He explained the system, showed videos of it in action, and checked every radiator. I'd definitely recommend Yost & Campbell to anyone, with a special mention for Alex's excellent work.

Jamal was excellent from start to finish. He showed up promptly, was friendly and efficient, and took the time to explain everything clearly. The level of service provided was top-notch, and his professionalism is something that sets him apart. Highly recommended.

Luis was very knowledgeable about his trade and explained both installation and maintenance options clearly. I liked his approachability - it started with the initial phone call, where he told me he was on his way, and continued through our consultation. His friendly demeanor put me at ease throughout the meeting.

Had issues with my Nest Thermostat showing "wires missing" after trying to reconnect WiFi. Turns out it was just loose wires that needed tightening. The technician, Jamal, handled it professionally, even for a relatively minor problem - his patience and attentiveness were much appreciated.

Update: Despite fixing the wiring issue, I still couldn't get the thermostat to connect to WiFi. A second visit by Jamal resulted in him bringing a new unit, thinking maybe that was the problem. Thankfully, he walked me through a factory reset process, helping me re-add and reconnect both thermostats and sensors without issue - great assistance from an understanding professional.

This technician is the best service we've had hands down. He's extremely polite and genuinely enthusiastic about helping, taking the time to break down every detail. His goal is to serve our interests when providing quotes. I'm actually looking forward to future appointments with him.

Angel did a great job. He explained everything clearly and made smart choices for our needs. We're really happy with the outcome.

I'm only giving two stars because the initial visit showed promise - the technician arrived on the same day and made a diagnosis quickly.

I have two Navien combo water heaters, one of which failed in my rental unit. My neighbor helped out by draining and cleaning it, but that didn't solve the problem. I called for more help, and another tech came who told me I needed a new pump. He also suggested replacing the control board at the same time, as they often go together.

The office sent an estimate, which arrived the next day with a total of $1,900. To be honest, I thought this was very high - I had replaced the pump on my other unit just two years ago and knew the cost of the part to be less than $200. When I asked about the reason for the price, the lady said it was estimated at 2 hours for labor, with the rest covering parts. That's it. No details were provided beyond that. As someone who has run an interior design business for over 20 years and regularly deals with contractors, I'm familiar with contractors marking up parts to cover their time sourcing them. But this quote is outrageous. It feels like they assumed a certain level of flexibility just because I'm a woman - it's not that hard to be transparent about the price! The lack of transparency in the estimate is appalling. I'm extremely disappointed and can't recommend this company.

Jamal visited our home for a system check, ensuring our heating worked correctly. He was polite and efficient, detailing what he did and how to maintain the system. His expertise extended beyond the initial inspection, offering suggestions on replacing outdated equipment. His professionalism is reassuring; I'd highly recommend his services in the future.

I recently had excellent furnace maintenance performed by David, who provided top-notch service. He's a knowledgeable and enthusiastic professional who took the time to explain every step of the process and answer my questions. His friendly demeanor made me feel at ease throughout the visit.

Jamal provided top-notch service. He thoroughly explained the system's operation and ensured everything was functioning properly. His professionalism and attention to detail were impressive. The entire experience with Jamal and Yost & Campbell was excellent, making them a highly recommended choice for maintenance work.

Jamal was top-notch - super easy to chat with and really knew his stuff when it came to fixing our boiler problem. He broke down the solution in plain English and offered plenty of alternatives, answering all my queries thoroughly.

I needed urgent generator maintenance before a potentially disastrous storm that could've left me without power. Erickson showed up despite treacherous weather conditions, which is more than I can say for others in similar situations. They thoroughly inspected the unit and confirmed it was functioning correctly. Given my history with Yost and Campbell on HVAC work - they've done quality jobs on time and fixed issues promptly when they arose - I'm impressed by their reliability in this instance as well.

As a first-time homeowner, I'm eager to learn about my new system. Jamal was great - he took the time to explain how everything works and answered all my queries. He also addressed my concerns, which put my mind at ease. The scheduling process with Y&C was efficient, and having live call assistants like Caesar available helped a lot. It's clear they have good customer support, as I got a response from a technician just the next day after speaking with Caesar.

I've updated my review on December 12, 2025.

Sam from the Yost & Campbell team reached out to me directly to fix the issue. Since we were members, he adjusted our bill for the replacement part and we only paid $255 instead of the original amount quoted.

Alex in the service team was understanding and worked with headquarters to resolve the problem quickly. The heat is back on and everything was taken care of in one day.

Thanks to Sam and Alex!

I recently purchased a new boiler from Yost & Campbell two years ago, which has already developed an issue. Initially, they had to return within a week to fix a gas leak due to a damaged pipe during installation.

Fast forward to now, it's been revealed that our circulator is faulty, requiring immediate attention. Waiting two days would cost $275, especially with the current arctic weather. However, since Yost & Campbell keeps in-warranty parts scarce but out-of-warranty ones readily available, we ended up paying a significant premium of $1,200 due to having elderly and pets at home. I'm extremely disappointed and wouldn't recommend Yost & Campbell for a reliable boiler.

We recently had our boiler fixed with Yost & Campbell Company and it was great from start to finish. The office staff were very responsive and answered all our queries. Their technician, who worked on site, was excellent - friendly and professional. He took the time to explain how everything would work before leaving and made sure the workspace was tidy. Overall, a fantastic experience and I'd definitely recommend the company to anyone looking for reliable service.

A technician from Yost & Campbell visited us during extremely cold weather in New York. Our furnace stopped working and wouldn't start back up, but the issue was quickly identified by this professional. He found the necessary part and returned on the same day to fix it. Thank you for a job well done - we were impressed with Ricardo's expertise.

A snowy winter night turned into a relief when Yost & Campbell sprang into action after my heating system broke down. They sent someone over the next morning, and he quickly pinpointed the problem - but unfortunately, they didn't have the necessary part in stock. The technician promised to return the following day or order it as soon as possible. Just an hour later, he showed up with the part and even enlisted the help of a colleague nearby to get it from them. I'm grateful for the tech, Shobba, and Yost & Campbell's top-notch service. It's heartening to meet workers who genuinely care about their work. Thanks again, Shobba!

Prompt and professional service from start to finish. The technician's prompt arrival helped alleviate time constraints, and a thorough inspection followed. Clear explanations of the work being done boosted confidence in the process. The service provider's expertise, integrity, and courtesy left a lasting impression. Their professionalism shone through, making them a trustworthy and recommended choice for home services.

I had an exceptional experience with my service technician, who arrived promptly and efficiently fixed the issue at hand. He took the time to thoroughly explain his diagnosis and repair process, including some details about the unit that were previously unknown to me when it was installed. The technician's professionalism and courtesy were impressive, making a potentially stressful situation much more manageable. His extensive knowledge of heating units is evident, and I appreciate the opportunity to have learned from him during this visit.

I've had mixed results with this company over several years, but they do get things done efficiently and offer fair prices for their work. Unfortunately, I've experienced two major projects where the installation was subpar, but the issues were eventually resolved. However, my interactions with the service technicians have left me underwhelmed. In one instance, when my boiler stopped working, the technician seemed clueless about thermistors and how to test them - I had to figure it out myself. More recently, trying to replace the anode in my water heater proved to be a challenge because of the complex piping setup; without a union available, it was impossible for me to access the needed area.
