LJ Refrigeration Company has been a Scottsdale family-owned and operated business since 1980, and a family-run business since 1963. Following our move to Arizona in 1980, we began building lasting relationships with fellow neighbors and businesses in Scottsdale by providing superior HVAC repair Phoenix.
We have been SO happy with Paul and his wonderfully reliable AC service! Our neighbor recommended him, and how positively different LJ is compared to other companies we've "tried" to work with! Paul communicates with you, does what he says, gets needed parts quickly, and works fast & very efficiently.
Heating and cooling can account for more than half of your home's total utility bill.* So when looking for ways to cut your energy costs, be sure to think about a high-efficiency system. High-efficiency systems are easily identified by reading the yellow-and-black EnergyGuide label found on the equipment.
Summertime is for lemonade stands by the mailbox, sprinklers in the backyard and coming in from the heat to rest in the comfort of the Arctic AC. We all love that summer sun. Here at LJ Refrigeration, we understand that when your air conditioning stops working you need an AC service that is done correctly.
Most homeowners don't worry about their air conditioning system until it begins to fail. This is because the AC usually does its job, and a homeowner expects it to work all the time. The truth is an AC has a lifespan, and it can be significantly shortened if you do not have your AC serviced regularly.

Jason executed the repair of my HVAC system failure with superb logic. Being a well-trained and astute technician, he began by inspecting the numerous wire connections accessible in the air handler compartment, and immediately discovered a problem with a pin & socket connector. Although this was obviously the failure point, Jason took the time to jump onto the roof (Jason’s humor) to complete a thorough inspection of the condenser unit of the split-system. The first-class services I received were much appreciated, and a reasonable service charge was the extent of my expenditure.

AC unit went down last night. We have a home warranty and made a service request. The assigned vendor called and said the earliest he could get here was next week. Hey, it's only the desert in July right? Called LJ Refrigeration and they dispatched Jason that same afternoon -- very knowledgable, professional, friendly. Repaired my unit at what I considered a very fair price. Can't thank them enough. Excellent service. They are outstanding!

I am extremely happy with LJ Refrigeration! Jennifer responded to me extremely quickly and stayed in great communication with me. They were able to send our Paul within the same day and earlier than anticipated. We addressed our problems with Paul and he was able to resolve everything right away. He was very patient and informational by providing answers to all the questions that we had. He also gave up great advice on how to upkeep our system. A huge recommendation from me to utilize this company for any of your HVAC needs!!

I wouldn't use anyone but LJ for my heating and cooling and water heater! They are efficient, clean, timely, professional and stand behind their products and work. No price gouging and no selling you something you don't need!

Somehow it has taken me many years to post a review for LJ. Sorry guys. I have been using them for 37 years and would never go anywhere else. My original units lasted for 36 years and recently went out. LJ promptly replaced them and I couldn't be more pleased, in fact Jeff was just here today for the annual check. The reason the old units lasted so very long was because LJ came out annually for check ups and tuneups, etc. This is clearly one of the best companies in the entire Phoenix area and I have and will continue to recommend them to others for HVAC service. They are always prompt, professional

We called LJ Refrigeration because our air conditioner went out in the middle of an heat wave. The receptionist was so nice and assured me someone would be out that same day in the afternoon. The owner and technician came and saved the day! They had the part I needed for my ac in their truck. They explained to me what happened and serviced both my units. They were so fast and had my ac unit running immediately. My family and I are so thankful for helping us out in a time of need.

A/C went out yesterday and got their number from the realtor who sold the home. Called at 5am and got the answering service. Spoke with them and they said that they would have someone call around 8am when the office opened. Received a call at 8:06 and let them know the issue and that the house temperature had gone up to 94°. They said they were booked for the day but they'd try to get someone out around noon if possible. Received a call from Jason at 11:40 that he would be at the house in 10 minutes. Found the problem right away, explained and showed what the issue was and got the A/C back

Very knowledgeable and super honest family run local business. I used them for a second opinion on work quoted by my former AC company and they saved me hundreds + repair hassles + provided great advice on avoiding future repair/service costs. They're now my AC company for any service or repairs.

Paul and the team from LJ Ref. absolutely exceeded expectations. Same-day service from time of request and an expeditious tune/up to the conditioning system. They even went above and beyond to identify and repair an air-handler leak that was driving up my electric bill!

Not to mention my home is COOL again.

Thanks Guys!!

We have used LJ for many years on two different houses. I have the greatest confidence in them and in their recommendations. A/C systems don't always choose the best times to fail, but LJ is always there when I need them. Once when we had a coil go bad, LJ recommended to me that instead of using them we use our homeowners warranty, saving us over $2,000. That is an example of how honest they are.

I contacted LJ Refrigeration through their website and requested a service call. The company had fantastic turnaround and service. They had an opening on the same day during a heat wave in Phoenix. I was very happy they accommodated me during this busy season.
The technician was on time and responsive to my needs. He asked me a few questions and immediately began to assess the issue with the air conditioner condenser. He informed me about the different freon types and the cost associated with repair and replacement. We also discussed various wireless thermometers and the technician educated

This company amazed us twice already with perfect customer service. We got a mailer for a March special to inspect the units. Jason the technician showed me everything I needed to know about the units and was very fair and I completely trusted his recommendations. Today about a month later one of the units suddenly stopped cooling. We called and they explained they were very busy but would try to squeeze us in. Jason again came and quickly assessed that the battery exploded and replaced and repaired. Didn't even charge which was unnecessary and kind. Can't say enough about this

I recently had our A/C units serviced by LJ Refigeration. The service technician let me know when he was on the way, and did the work quickly and efficiently. That part was excellent.
I had been quoted a price from the company through yelp. When finished, he gave me the bill. It was more than 3 times what I was quoted up front. This was due to the Freon he has to use. I paid the bill even though I wasn't happy. Mostly because I was not informed up front that it would be extra for things like that. Or that it could be that much more. I don't know what Freon costs, but it seemed

They fixed my 30 year old water heater when it stopped working. They put in a new heating element. They didn't tell me it needed to be replaced. Works great again. Honest company. Highly recommend!

I can't tell you how refreshing it is when you meet hard working and honest people. I had penguin air tell me I needed a new 3200 condenser on a unit that is only 6 years old, I had another company give me a quote for double the price of his repair. Finally I asked around and being new to AZ I decided to trust the reviews on next door, and found LJ. He came and had the AC up and running in 20 min. I couldn't believe it. Honestly, I'm almost in tears just thinking about how much I appreciate this company and the money they saved me. So many AC companies take advantage of women and

I highly recommend LJ Refrigeration! Unfortunately this week with excessive heat warnings, my home air conditioner quit working. After several days without AC and lackluster response/service from two other companies, I found LJ Refrigeration through a friend's recommendation.

While waiting to get quotes back from two other businesses, I called and spoke with Jennifer. She was super friendly, helpful and responsive. Within one hour, She had Paul promptly visit my home (no charge) and within two hours, they sent me two recommendations and told me they could complete the service that day

Very appreciative of Paul and his young associate! Last night, our a/c wasn't getting power. Of course, we're experiencing an excessive heat warning and the house heated up quickly. Kelly returned an emergency night time call promptly, added us to the next day's trips and told us that we would get a call if the technicians could make it out before the scheduled afternoon window. Bright and early, Paul calls to tell me that they will be there within 30 minutes. :-) Half an hour after their arrival, we're back in business! Thanks so much for your promptness, professionalism and

I'm from Deaborn, Michigan, visiting with my daughter in Scottsdale for a
break from cold weather. It was much hotter than I expected and the air
conditioner was failing. Fortunately, for us, my daughter had used LJ
Refrigeration on previous occasions and found them to be honest and
trustworthy. I was impressed with their courtesy and honesty. They
extended their work day to take care of our cooling issues on a very
hot day. Thank you !!!

HVAC service is as good as some other providers in the Valley. They do have some kinks to work out with their billing system. No capability to take payment at the time of service and homeowner has to track emailed invoices which is a pain. Paying upfront is most efficient for us so inconvenient not to have that option. Other than that they are OK.

These guys are great! I have a split unit in my downstairs that was freezing up. Service calls to other companies resulted in them wanting it sell me a new 5 ton unit. Paul Coen noticed that model was accessible for cleaning out restrictions, and an hour later I had a perfectly working unit at a fraction of the cost of a new one. I'm never calling anyone else for my HVAC issues-these guys are the most honest and competent people I've run across.
