“I was disappointed in their customer service and knowledge of my equipment. They claim to be a carrier dealer but, in 4 paid visits they did not repair my furnace.”

From the get-go Sean took the time to talk me through what he thought the problem might be with my HVAC system, gave me options to consider, helped me choose one that fit my budget, and proceeded to work quickly to get his guys out for an install of a new system (my current one was 22 years old and would've cost more to repair than replace). I feel like he had my best interest in mind, didn't push me to buy more than I needed, and treated me like a valued customer. I'll definitely be using Hollub going forward, as long as they continue to provide the same level of service, quality work, and HONESTY, which seems to be missing from a lot of companies these days.

“The phone representative was very knowledgeable, pleasant and helpful.”
The phone representative was very knowledgeable, pleasant and helpful. The technician came out promptly and diagnosed the problem (which confirmed our preliminary diagnosis). He had to return with a new fan motor and did so within a couple of hours. He was very professional and worked quickly to return our heat to normal.

Came out same day, solved the problem and gave some additional advice on my furnace, honest pricing. That’s what I need in a heating company. Found my new go-to for sure.

“We had an emergency with our hot water heater.”
We had an emergency with our hot water heater. They sent a technician the very same day to assess the problem, they installed a brand new water heater the next day. It has been working fine. Hollub is a good company to work with.

Had a great experience with Sean and the entire Hollub team - great communication, very intelligent (they even flagged an issue that was undiscoverable but arose during installation!), came out for a second viewing to ensure the proper scope of work, and were very respectful to me and my living space.

“Thank you Hollub Heating, Inc.”
Thank you Hollub Heating, Inc. for not having traveling restrictions, unlike the company I purchased the unit from. Oddly, they didn’t have a problem traveling to my area to sell me their product, but coming out to service it was out of their district. Hollub sent a technician out the same day I called. The technician was courteous and professional.Thanks again for exceptional service.
PS: I later received a phone call from Hollub stating that they made a mistake quoting my bill and to my surprise the amount was less than the original amount. NOW THAT’S RARE!!!!

“I have used Hollub Heating for over 15 years.”
I have used Hollub Heating for over 15 years. I’ve had excellent service each and every time. Hollub installed a brand new furnace about 10 years ago and its running great. Their technicians are professional and many have been with the company for years; in fact Pat has worked my furnaces for 15 years. He was always respectful and takes time to explained the systems to the residents. The office staff is wonderful to work with also. I highly recommend Hollub Heating for all your Heating needs.

“The motors in my heating vents needed replacement and I called Hollub.”
The motors in my heating vents needed replacement and I called Hollub. We set up a service call and everything from then on went exceptionally well. The obsolete motors were replaced, the fans were thoroughly cleaned and now I look forward to warm winters ahead. Thanks so much to Hollub's Sean and Mike for their timely and responsive service!

I have used Hollub for over 25 years and this is the fourth furnace they have replaced for me - the first three were in a 3-flat that I owned and today was in my townhome. The blower motor on my 18-year old furnace could have been repaired, but I did not want to invest more money for a furnace that was at the end of its useful life. They laid out all the options - repair the motor, replace the furnace with a similar model, or replace the furnace with a more efficient, upgraded model - and the pros and cons of each so that I could make an informed decision. I chose the upgraded model and it was installed in less than 24 hours from when I first called them. They were responsive and worked efficiently to get my heat turned on on one of the coldest days this winter. After a few hours with the new furnace, I'm pleased that I chose the upgraded model since it is quieter and heating my home better at a lower temp than my old furnace. I continue to call Hollub decade after decade because I know they will respond quickly to my issues at a fair price. Also, it's nice to patronize a family-owned business.

“Hollab saved us 3k.”
Hollab saved us 3k! We had a heating issue in our condo.
We called Aircor because they had awesome reviews on Yelp. They came out to repair the heater, said a part needed replacing. They replaced it but it didn't fix the issue.
We end up calling them back two weeks later. They said we need to replace the heater and it would run us 3k. We decided to get a second opinion.
Called Hollub Heating because they originally did the work for our building years ago. They were super nice and there in less than 24 hours. They found there was insulation that was clogging the blower and removed it. Heater works amazing now.
