Job was done very well and i was referred by a friend that uses them. They moved my furnace to the attic and now i have a closet.

John and his guys replace my air conditioning and heating unit. His pricing was competitive. his workers were great and left my place as clean as they found it. Would highly recommend! read more

Didn't call me back.after they said they would. Glad they have so much business but disappointing.

It's been several years since the Paterno family installed our AC but it's been working flawless ever since. Installed quickly and carefully and sized for the house. Very happy. read more

I obtained several quotes and references and chose Paterno Heating & A/C to replace my central air conditioner system as well as my furnace. The company is family owned and operated. John Paterno is the owner and is very informative and readily available by text or phone to answer questions. The work was completed as scheduled and the quality of the service was outstanding. The cost was very competitive as well. I highly recommend Paterno Heating & A/C for your heating and cooling needs. read more

John came out on a Sunday, diagnosed my AC issue immediately and quickly had me up and running again! Professional, courteous and experienced! Highly recommend! read more

John is the best of the best. We were out of town about a year and a half ago and in a heat wave our air went out. We were on the East Coast our son was house sitting. John came and replaced a coil and saved us a ton of $. Now today our heat upstairs has been out for days. It's so cold out there. He came and changed a fuse and we are good to go. This man is so honest and so knowledgeable. Very grateful for him read more

Does not respond to phone calls and text messages to fix a problem. He installed air conditioning in the summer of 2022 , by spring of 2023 air conditioning unit had a problem. When he finally answered a text and/or phone call, and there were many before he responded, he would promise to come out and not show up. When he did show up, (12 days after first call) he said he fixed the unit but it immediately malfunctioned and he was called again, 10 days later I'm still waiting for the unit to be fixed. read more

John Paterno and his company are by far the best company for Air Conditioning and Heating in Southern California. John and his team are hardworking, caring and kind when it comes to their work. They clean up after themselves and know exactly what to do. I highly recommend their business! Bill and Charlotte DuFour read more

John really saved the day for me. Came out on a holiday within 3 hours of me contacting him and got my AC up and running in no time. Price was very reasonable and service was very friendly. He also looked at my filters and showed me how to get better airflow. This unit is now running like never before. The house feels fantastic, just in time for another 100 degree day. Highly recommend. read more

Our air conditioning unit went out during this heat wave and John Paterno came out in a timely manner and fixed the problem!! He was early, professional and reasonably priced!! If you are looking for a company to put in a unit I highly recommend Paterno Heating and Air Conditioning!! read more

From the first meeting with John, I found him easy to talk to and I had plenty of questions. He answered each question patiently and I felt he was listening well. He has plenty of experience in this industry and he comes across as a real expert. Scheduling with his team was easy and he stayed true to the budget and timeline. They worked fast and they cleaned up when done. I highly recommend this company for all your HVAC needs. read more

I'm a past customer. Similar to my last experience with this company, once they completed the work, they never responded to any of my calls or texts. read more

I recently contacted John and his business about possibly hiring him to service my stand up, portable AC unit due to light mold that had formed. I reached out to him through his website so I was unsure if I would ever get a response based on my experience reaching out to companies on their websites in the past and not having great success with any correspondence. John texted me personally a couple of hours later, giving me some brief instructions on how I can service the unit without paying for an expensive and possibly unnecessary cleaning. I was very impressed with his effort to help a potential customer and his integrity to supply an honest answer and not taking advantage of a client. When I do need actual assistance, you can bet I'll be reaching out to John's business in the near future. read more

We had to have a new A/C unit installed and John did a terrific job. He did everything he said he was going to do and more. His price was fair and he and his crew showed up on time and were polite and professional. They finished up in one day and the system is great. We were replacing a system put in by another company not all that long before. There is no question that I would only go to Paterno's for any air conditioning or heating needs. read more

I expected the worse case scenario. Perhaps the most honest assessment I have experienced in any kind of repair. They could have charged a lot more, but didn't. Not because I'm nice, but because I believe this is how they do business. Thank you again, I will recommend them to anyone needing a recommendation. read more

This is a most tardy review...apologies one company. About three or four years ago, I met John Paterno while he was responding a new owner home (condo) inspection repair need. Asked him if he could check my A/C unit when finished. It was an older unit and needed "Freon" (R-22) which has been become obsolete and pricey too. He said if it didn't resolve my problem he'd give us a credit when replacing the compressor unit. Sure enough, it went out, he kept his word, giving the full reimbursement discount. I recommended him to three neighbors for three A/C units--each were very satisfied with his price, timeliness and workmanship. Saw him again, maybe a year ago, to replace a compressor fan that was still under warranty he said. Couldn't have been more satisfied. Thanks John and Paterno Heating & Air Conditioning. read more

Paterno has installed 5 full home air conditioners for us over the years at different properties, 3 months ago he installed a new Samsung system in our home. It is still not working and the effort by Paterno's to fix the problem in my opinion has not been adequate. We're very disappointed with Paterno and Samsung also seems to be unresponsive and uncaring about customer service. I wish we could undo this situation, but definitely stay away from anything Samsung. read more

The best of the best! We are so happy with the service we received from John and his team. These guys were awesome! They were always on time, worked hard and made sure everything was perfect. We're so happy with our new HVAC. Highly recommend! read more

John is awesome! We've used him for years and he never lets us down. He's reliable, trustworthy and always finds a reasonable solution that won't break the bank. We really appreciate having him locally! read more

John Paterno and his team were recommended to me and my mom by a family friend, and I've got to say I'm very thankful for that recommendation. Our house was undergoing a remodel, and the central heating needed to be changed because it was just too old to keep being used. John came in and explained how everything was going to work: he explained his process, explained why he trusted some brands of air conditioners and heaters over others, and explained some of the regulations that influenced his decision making. He explained some of the mechanics of how a thermostat is influenced and made sure we understood why the thermostat had to go in a certain place, etc. His team took out all of our old heating system and disposed of those on their own in a timely fashion. The new system looks great, and bought us a Google Nest Thermostat to use with it which works wonderfully. I believe most of the delays we experienced with him were due to Covid and he did his best to communicate that so we had accurate time estimates. He always work a mask, as did his crew. They were very nice and made sure any complaints or concerns we had were addressed. My only minor complaint is that there were a couple of times when they did not appear to approach our desired end date with as much urgency as we had wanted, but I believe that is a common complaint for any type of contracting work. Besides that, I have no other major complaints and would recommend him to anyone looking to completely replace their AC/heating, or even if they just needed smaller modifications. Would give 4.5 stars if Yelp allowed halves. read more

John is great. John installed my AC at my previous home and he did such a great job I still use him for any AC issues we have. Today my AC unit wasn't working during this heat wave so I called John. He came over within the hour and repaired my AC unit quickly and efficiently. Great service and great work. Very satisfied. I would highly recommend John and his guys. read more

The owner, John, recently replaced my home air conditioning unit. He was referred to me by my neighbor who had the same work done and was very satisfied. I am glad I took her advice ! He completed the job in 3 1/2 hours with a crew of 3. His first visit was to add Freon to my old unit to keep it working until I decided on a date for the new installation. He returned to examine the job and give me a quote which was extremely fair and reasonable. On the day of installation he was punctual and his team was well-organized. All went smoothly and professionally. John is a friendly and great guy who has 38 years of experience and knowledge in heating and air conditioning. I learned that he is well known and highly respected in my community. I guess you can tell that I would definitely have him return for any heating and air conditioning work in the future.....he is the best ! read more

Paterno's Heating & Air Conditioning just completed the installation of a new HVAC system in our home.... all I can say is WOW! Leonard & John Paterno (brothers) run a family business and are truly dedicated to "doing it right". The installation went exactly as promised. They removed the old non-functioning furnace, A/C and 54 year old duct work & refrigerant lines. Then they replaced everything with the latest most efficient equipment. The team worked together and were respectful, neat, clean and treated our home as if it were their own. We are beyond pleased with the entire project and all this at a very fair price! If you're thinking of having heating or air conditioning work done, I strongly recommend you call Leonard or John. You won't be disappointed. read more

Owned by two brothers. These guys are tops! They will come to your home and give you the best prize, best workmanship, and the best equipment in the business. We have had them do both our home and my mother-in-laws home. Fully licensed - 562 596 8368 - tell them mike and suz sent you. read more

After 4 quotes, my daughter and I agreed on Paterno's. It was the manner in which they spoke, the equipment choices, location of the installation and finally the price. I did the electrical panel upgrade needed, as I am retired and had the time. John gave me his ETA and I worked towards being ready on my end. When they team arrived they went right at the job with quality professionalism. They were always conscious about cleanliness of my daughter's home and because she works at night in NICU, she received her needed sleep, without much noise. The whole job took less than a week and the system was well explained. I continually reccomend Paterno's HVAC to my friends and business owner's. Randy Perl read more

Just had Paterno Heating and A/C install a brand new central air system for our home in Long Beach. We have a flat roof so were considering ductless mini split systems as well as potentially building soffits inside, but those options were very expensive. John was very upfront and knowledgeable, as well as competitive on price. His experience with our roof type, and being a local Long Beach resident was very attractive. He also strongly recommended us to obtain permits for HERS and city inspections, where other vendors steered away from that. He ALSO removed and patched our old wall heaters (3 of them) which was an added bonus. We are loving our new Trane 15 seer packaged unit and keeping cozy in the winter cold, while looking forward to staying cool in the upcoming Long Beach summers. Call John if you're looking to upgrade or install new. You won't be disappointed read more

If I could give John, Leonard and their crew 10 stars, I would. We live in Lakewood, and the crew just did a full "cut-in" at our home (a full cut-in means they had to install a furnace in the attic, do all the vent & duct work, and install the condenser in the backyard. These guys are as honest and straight-shooting as they come. They won't oversell you on stuff you don't need like some of the bigger name companies do. They've been in business for a long time and know their stuff inside and out. Leonard came out for the initial estimate, and he was honest and easy to talk to. John is amazing and so knowledgeable, friendly, and honest. The work they did was so professional and they showed great care and attention to detail. AWESOME! I highly recommend Paterno's for all your HVAC needs. read more

After an element failure John Paterno performed diagnostics the next morning and got a part that was replaced promptly the next day. Great service! read more

John Paterno and his guys were great. Just put in a new central air unit and a mini split for our upstairs bedroom. Felt he was very reasonable and delivered exactly what he said he was going to do on the exact date he said he was going to do it. Appreciate it very much! Thanks John! read more

A few weeks ago we started to notice that our heater was blowing cold air, sometimes for over 30 minutes after our heat got to the set temp. All that cold air caused our heater to kick back in...our fan was constantly running! We tried troubleshooting, replaced filter & thermostat (fan on auto) with no luck. I put out an APB on YELP for help and John was one of the first to respond. He was able to squeeze us in his schedule on 12/30. After running a complete diagnostic he discovered we needed a circuit board. Instead of leaving us shivering through the New Years holiday he made a few calls and was able to pick up the part and install it the next morning - New Years Eve!!! He was extremely knowledgeable about our heater and all things HVAC, including new state laws, etc. that he shared with us. Professional, personable, and honest. Will recommend to my friends/neighbors and definitely use his services again if we have a need. read more

As others have said, five stars are not enough; Paterno's level of service deserves twice that, and more. They were recommended to me by a trusted friend, and I am glad I took the advice; Leonard & John are extremely efficient, knowledgeable, and professional. They provide that "old-fashioned", trustworthy, and caring service that is almost nonexistent in today's world of faceless franchises that only care about their bottom line. I have an A/C system that needed a slight fix, and they did it without hard-selling me on replacing the entire thing. And, they did top-notch work with it. Later I had another issue with the system, they fixed that, too, in an incredibly speedy and efficient manner. I also had them install a small, new system and could not be more pleased with the equipment supplied and the meticulous installation procedure. I don't write reviews often, but Paterno's are very deserving of the praise. read more

Good and honest. They know their stuff and are very responsive! John helped me out of a bind when our a/c went out during our heat wave. Oy vey! Thank God I called them. They had us up and running again in an hour! read more

I had a problem with my Upstairs AC unit and called Paterno's. These guys have been in business for a long time so they are busy. John texted me back after I left a message and we set an appointment that was convenient for both of us. John let me know he was stuck waiting for an inspector so his brother Leonard came out for the service call. He asked what the problems I was experiencing and then we looked at the condenser unit. He said turn it on and we'll know one of two things. Sure enough I had a blown capacitor. He took his time to show me how to access the capacitor, and explained everything in plain English so I'd understand if I ever had a similar problem with the other unit. Leonard clearly was a pro and took pride in helping out a new customer. I'm a local Realtor and have seen their service stickers and their work van for years. Now I know why they've stayed in business for so long. They're honest, fair and professional. Highly recommend Paterno's. read more

I call twice over a two week period for Air Cond. service/repair. Never received a call back. I live with a few miles of their location. Even if your are busy a call back is necessary. Went with Performance Air, another company and they picked up the call and came the next day. read more

After 10 years of my husband making this his #1 request, and me not wanting to spend the money, I caved in and we had A/C installed. Paterno Brother's were top notch, on time, efficient, clean and tidy, and after a year of it working in sync with our heating system, I can honestly say, I should have listened!!! We have it pre-set to go on when the house reaches a certain temperature, and the same with the heat in the winter (is there a winter in California?) Anyways, if you're considering A/C do yourself a favor and call Paterno Bros. We called 3 different companies for estimates and Paterno Brother's weren't the cheapest but they weren't the highest either. They were referred by a friend and I have referred them now myself. read more

Excellent work, professional, competitive prices. Installed new furnace and A/C system and we are very happy with their work.

Installation of a new air conditioning and heating unit by John Paterno and his crew were great, professional people. Everyone I spoke with was polite and easy to deal with. They were very knowledgeable of every aspect of what we needed. I would recommend Paterno Heating and Air Conditioning. They are "Top Notch"!!! read more

Zero stars. Never called me back. How do you run a business that way. Will have to give my business to someone that wants it.

Very satisfied. I had a thermostat replaced. John stopped by in the afternoon and even went up into the attic to checkout the HVAC unit and condenser outside. Said everything is running great (it's 20 years old!) and even gave me some pointers on what to look for when a problem may be looming. Such a genuine guy and personable. You can tell he loves his job. read more
