— Mayer C

Let me tell you about this company, A++  they did whatever needed to get us back up and running, they definitely take care of their customers.

— Tim J

Alpine came recommended to me and they did disappoint. I wish we had them as the original installers on our unit. All the technicians have been able to thoroughly explain the work and answer our questions. I also need to give a huge shoutout to Liz, the office manager. She has been beyond helpful in every way possible! Being that we had so many issues, I was dealing with her on a lot and never did she get frustrated or irritated with me or the situations that would arise. Liz was always responsive and able to communicate everything technical to my level of understanding. She is a true gem to have on the team!!

— Monique M

Dave was amazing! I’m so glad I called Alpine. The professionalism and quickness on getting my house nice and cold even in this 90 degree weather. He was very knowledgeable in what he does and gave me great advice on how to keep my house nice and cold. I will definitely be calling again whenever I have AC problems. The service was definitely A plus quality!!!

— Delmi S

Keith was great! I had called multiple companies that gave me the runaround and tried to sell me everything while I have a brand new system.  Keith came in and ran his diagnostics and fixed my unit in under an hour! Great service, friendly and prompt – Highly Recommend

— Kimberly W

I called Alpine and they were at my door not even three hours later . Issue fixed promptly. Professional honest and reliable ! Call them right away !!! You’ll be well taken care of ! Thank you Alpine.

— David W

I live in Monmouth County and I met with three different companies about replacing my air conditioner and furnace for my home. Among the three companies I spoke with was what I believe to be one of the largest HVAC companies in NJ.   That said, I selected Alpine.  My husband and I reviewed the proposals carefully and we decided to go with Alpine.  They explained everything carefully to us and we clearly felt they were the most honest of all three companies.  There was no funny business – no hard sell, we felt very comfortable with them.  The installation crew was excellent!  They were polite and were very efficient.  They cleaned up after themselves and left the areas cleaner than they found them.  I recommended them to my neighbor, and I believe they were thrilled with them as well.

— Cynthia P

Cecil was great – came on time, very pleasant and knowledgeable. Problem is fixed. Would definitely use them again. Thank you!

— C W

I have a two-floor house in Lakewood Nj. We had several technicians come to our house to find out why our bedroom was three degrees cooler than the rest of the house. The technician was very professional and was very pleasant. He fixed the problem and advised us on other HVAC issues in our home.  I would highly recommend this company! Great professional knowledge and customer service!

— Dina D

The day after Christmas we lost heat, and I called Alpine.  The technician came and determined that my heating unit was shot. The system was very old, so we opted to replace it with a new and more efficient heating system. The Alpine rep left us with a couple of space heaters to get through the weekend and the installation team arrived on Monday to install our new system.  Unbelievable service!

— Jess P

I run a management company and I use heating and cooling guys every day of the week, I just never had anyone like Alpine Air, when you call them they show up  and are professional, they clean up after himself themselves and do perfect work, and when they say they’re going to be there they’re going to be there, I never had that with any other company.

— Efraim T

Called Alpine when my AC went on the fritz and they sent someone out right away. The technician was excellent. He was very knowledgeable, friendly and polite and he gave us some great tips on how to maintain our system – which by the way we did not purchase from Alpine. Great service, would definitely recommend them.

— Robert P

My neighbor recommended these guys and they were great!  Benny was in and out in a flash and my system is running like new. Can’t believe the difference.  I’m very pleased. Thanks Alpine.

— Jordan Z

Terrific service, the Alpine technician arrived on time, diagnosed my problem and took care of it within an hour.  I had called two other HVAC companies previously and neither was able to fix the issue.  Great customer service!

— Jim B

I have an 8-year-old system that was constantly giving me trouble.  Seemed like every year I was calling in for service. Switched to Alpine two years ago and signed up for the Alpine maintenance program and it’s the best thing I’ve ever done.  The Alpine rep comes in prior to each season and tunes up my heat and AC system.  Haven’t had a problem in two years. Very satisfied.

— Paul D

Always super helpful and on time!

— Anthony F

My house is 20 years old and the heating system finally went.  I called three companies and Alpine was clearly the most professional. No hard sell at all.  I was provided with several options for replacing my system and I wound up choosing a Ruud system.  The crew showed up on time and installed the system in one day with no hassle or inconvenience to my family. Now my new heating system works great.  I highly recommend Alpine.

— Riley M

Needed to replace our AC after years of it breaking down.  A friend recommended I call Alpine because they were very pleased with their service.  I spoke with Benny and he walked me through my options.  Our new AC system was installed the next day and the price was very affordable. Really great company!

— Jordan S

My neighbor recommended Alpine to me for replacement of my AC system.  What a great experience.  The salesman was very thorough, and the installation crew was wonderful. I highly recommend Alpine.

— Cindy R

My husband called Alpine because our heater was making strange noises.  Benny came out and quickly diagnosed and fixed the problem.  Didn’t need to spend a fortune on the repair and we weren’t railroaded into replacing the system like I have been in the past by some other contractors.

— Danielle P

Decided to purchase a maintenance contract from Alpine three years ago.  Best decision I ever made.  While Alpine did not install my original heating and AC unit they have kept in running smoothly the past three years.  I highly recommend their maintenance program.  My system is 15 years old and still running great. 

— Alex P

Keith was excellent.  He figured out our problem in no time and got our system up and running.  So glad I called Alpine – highly recommend them.

— Sarah G

Can’t say enough about Alpine. Great service, polite and professional crew.  I just recommended them to my sister-in-law and she’s pleased as well

— Janice P

A++ Very pleased with Alpine.  Very efficient system , no haggling and a great price.  Highly recommend.

— Devin S

Purchased a new home about 8 years ago and had some issues with the air conditioner.  Called a very well-known HVAC company because I always see their commercials and their trucks on the road.  Salesman called me back and immediately tried to sell me a new system offering all sorts of promotions. It just didn’t feel right – an 8-year-old system shouldn’t need to be replaced.  I called Alpine and Cecil came out and took care of my problem in less than two hours.  Very refreshing, an honest and ethical company focused on solving my problem and not just trying to sell me a new air conditioning system unnecessarily.

— Dan L

Had an issue with our AC several months ago and called several popular AC companies to come check it out.  All of them except Alpine tried to sell me a new system over the phone.  Alpine sent out a technician who fixed the problem and never attempted to sell me a new AC unit. Definitely an AC contractor you can trust!

— Robert R

Recently purchased a 25-year-old home.  We knew that we needed to replace the heater and air conditioner.  Called three companies including Alpine Air.  Met with all three companies and decided to go with Alpine. I’ve since heard horror stories about the other two companies.  Interestingly, I almost didn’t call Alpine Air because they weren’t as well known as the other two companies were but luckily my brother recommended I give them a call. So happy I did.  The guys did a great job and were very professional.
