Your Trusted 24/7 HVAC Service Experts in Guilderland, NY.

Anthony is awesome. I like how ALJ is his business and not a corporation. He was extremely personable, knows his stuff and prices fairly. I highly recommend to anyone in need of HVAC servicing or replacement.

Awesome service.. very professional.. even came after hours. Much appreciated.

Anthony is knowledgeable, courteous, friendly , reliable , prompt and a pleasure to have him come in my house for any HVAC Service I have needed in the past 2 years.Anthonys pricing is very fair as well. I wholeheartedly recommend Anthony for anything that is HVAC related. Best regards, Ed Martenis Latham, NY

He installed 2x Furnace and 2x AC (replacing the old furnaces in my duplex and adding AC to both). Good work and good price. He came when I called a few months later when I had a switch that needed to be turned on.

I am in the process of purchasing a second home and needed an HVAC expert to inspect current system as home inspection warranted this. My current HVAC group refused to do so indicating liability issues as I didn't own the property. Thankfully they are in the minority. Anthony at ALJ Heating & Cooling accepted the job, was prompt and courteous. He additionally provided his liability documentation per current homeowner's request. System will need to be replaced as it is about 30 years old. Anthony will be getting my business for the replacement of the mechanicals, as well as on going service to my first home. I am dropping the group who refused to take a look at the 2nd house. Customer service is extremely important to me. Anthony gets 5 stars out of 5.

Anthony from ALJ Heating and Cooling was very professional and courteous. He gave us an honest and fair estimate for a replacement central a/c system (unlike many other company’s who gave us outrageous estimates). He replaced our a/c unit, working in the rain for hours.. His workmanship is excellent and we would highly recommend this company .

Anthony was a pleasure to work from start to finish. My AC unit went out so I started looking for quotes. I called Anthony because his company had some really good reviews. Within a day or two, he was at my house assessing the issue and explaining what needed to be done and why. As a newer homeowner who is not very handy and has not had to do many home repairs, he was super informative and helpful. I also received another quote from one of the larger, well known HVAC companies in the area. However, because Anthony was more helpful and affordable, I went with him. He and partner, Zay, installed the new outdoor AC unit, indoor handler unit and new line sets yesterday and they were great. Professional, polite and they did a great job. I would recommend Anthony to anyone needing HVAC work. He will be my first call for any other HVAC-related maintenance or repairs.

This is a great company. My central ac died on Sunday, the technician came out on Monday, fixed my issue and got my ac running again. Price was excellent. Will definitely use them when I replace the unit.

Anthony was on time or provided updates about delays. He responded all requests within an hour or less. He gave technical information about what he was doing, including why he was selecting certain brands, or what options we might have. He was very professional at all times. Highly recommend.

I very recently bought my first home-a fixer upper. The AC units in my new house needed to be updated and I was referred to ALJ Heating and Cooling. This was a great referral indeed. I was provided with quick, efficient service, at a very reasonable rate. I plan to purchase another property in the next few months and I will definitely be using ALJ Heating & Cooling services.

Wow! Anthony was a breathe of fresh air! I went through everything I had trouble shooted myself with our central air unit to come to the conclusion I had come to. Not once did he make me feel inadequate or uncomfortable as many other professionals have. He serviced our unit at a reasonable price. Ive already referred him out to a friend of mine and will definitely be bookmarking him into my contacts for the next time something comes up. Thank you again Anthony. A++ service!

I would like to thank Anthony for his service. He fixed my central air unit at a reasonable price and was very professional on top of being kind.. He’s already in my contacts and I’m definitely referring him to friends and family… Thank You Again Anthony

My only regret with Anthony and his team is that I didn't contact them sooner! Exceptional work putting in a new furnace for my family and I. Was out for an estimate the same day contacted. As soon as the parts were in there were here to install. Communication was great, work was great, overall experience was great and helpful during a stressful period. I would highly recommend ALJ to anyone looking for HVAC work. Will definitely be using them for all future maintenance and repairs.

Anthony was very prompt and came to assist within a day. He explained the AC issue(s) clearly and was very patient. Would recommend 100% especially if trying to find an HVAC person.
