Randy and team are fast to respond. Very knowledgeable and they diagnosis my problem in a few minutes vs another company I called who took two hours and tried to tell me I needed to rebuild my AC system for thousands of dollars! Randy ordered the part and fixed my AC system the very next day. Grateful for their honesty. Will call them again if I need help. read more

Don Glenn Heating & Air Conditioning - Heating & Air Conditioning/HVAC Near Me - Los Angeles, California

Randy DeVera - whose dad has been running Don Glenn for decades - showed up 45-minutes early, diagnosed the problem and fixed it quickly. This, after two different companies tried to dick me around, including one that wanted me to do a deep coil & condenser "oxygen" clean for $200, and another company that wanted me to replace the entire unit ... for $5500. I just needed a capacitor, which is the most common problem in hot weather. Especially given LA's power surges. If you're looking for an HVAC contractor you can trust, I'd say these are the guys. read more

8/23/2019 Randy and team were great. I had a AC unit installed 3 yrs ago by another company and the unit lost all of it's freon. Long story shorty that other company ripped me off. I called Randy from a referral from a colleague and he jumped right in, crawled up my house and diagnosed the issue. Gave me few options but I elected to have them replace the part vs dealing with the original installers. Randy was prompt and professional. His team came over few days later also jumped right into the project and removed the defective part and got everything buttoned up. Shout out to Joe and his team as well for great professional fast service. You won't go wrong contacting Randy, he is honest and straight forward. read more

Randy is the man! I've had multiple issues with my A/C unit and it's always good to get a second opinion. I'm sure glad my second opinion was Randy as he pinpointed the issue immediately and was able to order my part and install it in less than a week. The other options from a previous company was that I should replace my entire unit, which was only installed in 2013. It was only 5-6 years old when it first started having problems so I'm glad I didn't have to spend four times more money. Enjoying the cool air during this hot week, thanks to Randy! read more

I got a quote from another company to fix my AC. I was quoted $6800 and that I needed to replace my entire unit. Then I called Don Glenn. He found a simple solution to my AC issue that did not require replacing anything, saving me thousands of dollars! I canning recommend this company enough!!!! read more

Randy get's it done, his team and him got a new install done in 2 days and you couldn't tell they had been there other then the cool air they left behind. Responsive and very easy to work with, if I ever need any hvac work done in the future I will definitely go to them. read more

I have an appointment today at 8am but no one showed up to fix my ac conditioning. I was disappointed but one one communicated with regarding maybe a time change. I scheduled my work schedule around this appointment and it's been an hour. They didn't communicate with me if it was an 8am to 10 Am appointment. I did call but I only receive their voicemail. read more

Randy is an amazing technician! He came to my house to give me an estimate for installing an air conditioning and heating system. He was right on time and he accurately and patiently explained my options. He also answered all of my questions. This company has been operating since 1984 and that says a lot about their family business. What I like the most about Randy is that he is cheerful and pleasant. This is the kind of people that I want to deal with, especially in these difficult times for our society. Thank you, Randy, I highly commend you. read more

My family has lived in Pasadena since 1979. I wanted to share the great experience we have with Andy & Randy over the past years (decades). My family trusted Andy for our air conditioning needs in the 90s, and after his retirement we continued with his son, Randy. Randy is an expert diagnostic HVAC engineer/technician, and he is trustworthy & honest. Randy solved various problems we had with our HVAC system that was installed by a general contractor in a 90s remodel. He has recently upgraded our thermostat to a Smart Home device. We want to thank them for the excellent service! read more

Randy and his team are the best. Their customer service exceeded my expectations. I cannot rave anymore about their service from getting the quote to finishing the job. They're definitely a company I would recommend to anyone for their customer service and affordability. read more

Excellent service all around : highly recommended company . Randy is very professional & fair in his pricing. Reliable & trustworthy are the best descriptions of him & the company . read more

For well over a decade, we've depended on Don Glenn to fix the AC that came with our home. (We run it alllllll through summer.) They've been able to diagnose the problems quickly, and provide options on fixing it. Because of them, we've been able to keep our aged AC unit running, until we're able to replace it. Randy and his team are down to earth, honest and our go-to! Thank you Don Glenn! read more

This review is long overdue. Randy and team are great! I own over 5+ rental properties in Eagle Rock and always rehabbing new properties i acquire. Don Glenn has been my "go to" for all HVAC needs for years. Family ran business. Easy going, Fair, honest... and always professional. Im sure they get busy on hot weather, but still very responsive and always willing to fit me in even with smallest issues. He's even come through on a several occasions to troubleshoot and replace blown fuses, etc.. and didnt charge me for them even years after original install date. Highly recommended!!! read more

Heard about this company through our Nextdoor App. My old (1948)floor heater went out during the coldest week of the year. Called Randy on Tuesday 2/20. Randy & his assistant Joel showed up promptly at 9am as scheduled on Thursday 2/22. Thank God it was something minor. They were quick and thorough. Also, both kind and professional. Price was reasonable too. I was very pleased and highly recommended them. read more

I had my Air Conditioning checked by Service Champions yesterday and their technician named Jacob recommended to replace the entire Air Unit and Heating Furnace (read/check my review on Service Champions) A good friend of mine recommended to call Randy from Don Glenn Heating, not only he came the same day (on his way to another appointment) He fixed our Air Condition & we do not need new Air Unit nor new heating furnace since the only problem was a burnt wire. Honest and thorough person/company, very seldom we find one especially this day and age. read more

Randy repaired our floor furnace this past winter. If he had not fixed it, I would've spent a second winter suffering without heat being I have arthritis in my spine and the cold weather affects me. He replied promptly to my message. He scheduled a visit, assessed the situation based on a visit from the Gas Company and before I knew it, my floor furnace in our 1922 home was up and running with no problems. I highly recommend him. I know a lot of homes in the area have floor furnaces and I was, honestly, worried we would have to look at new options were I unable to find someone familiar with them. Thank you Randy! I will continue to recommend you. read more

Randy, the owner of Don Glenn Heating & Air Conditioning, was recommended to me by the previous owner of our house when one of our dampers failed. I left a message for Randy and got a call back within the hour. He came out the next day to confirm my diagnosis and quoted me a fair price. We scheduled the repair for a few days later (I wasn't in a rush) and he showed up on time and had it fixed in a jiffy. There was no mess, he was polite and just an all around great and trustworthy guy. I'd definitely use him again. But hopefully he fixed it so good that I won't have to. :) Highly recommend. read more

We've been working with Randy for about 12 years now, and have always found him to be responsive, prompt, and fair in his pricing. He's kept our split system running smoothly and handled every (usually minor) glitch efficiently. We recommend him and his team highly. read more

T'was the first day of the heat wave, 7/5, my A/C broke, called this HVAC Co., Randy answered, told him the problem of my A/C. Diagnosed it over the phone; he came over on the 7/10 with the new replacement part, opened up the AC, did some other checks, installed the new part and "Voila", my AC is working again. Good price, I'm a happy camper! read more

My air condition has water all around and there was ice on the outside condenser unit . This guy Randy came to my home and check the unit and spend half an hour and said everything is good nothing looks odd, add the 1 pound of Freon for 50 bucks plus the labor. It was morning time and i was changing my flat tire so i didn't pay any attention. He could not open the top part of Furnace ( v shape ) and he just bend the whole thing and said everything is good. Real Story begin after that we use the air condition that night and water was all over the place and it stop working . My Blower Motor got short circuit. I start calling Randy and acceidently he pick up the phone and said may be change the electrical plug and it didn't work i will check out and after that i may be called him more than 10 times and left the message .....no response, He is not a professional and he could not even open the unit...how he going to fix anything and i have to spend more than $1500 to fix the problem, and problem was in the V shape furnace unit it was dirt that blocking the air and coils was getting frozen and when i turn off the unit... water melted all around the unit. if he opened the unit and clean the dirt on the first day, i didn't have to spend this money and go through 3 week without air condition. No technical knowledge and no decency of answering the calls even he left the mess in people's home. Don't call this guy. read more

My experience with Don Glenn went from great to bad. They were recommended to me by my plumber. I called Randy on the morning of 7/5/18 because my ductless mini split unit had a cracked refrigerant tube and needed to be brazed/welded back together. Randy and Joel showed up as promised that afternoon and re-attached the tubing, re-installed the unit and then charged with the R410 refrigerant. Everything worked fine just in time for the heat wave. That was GREAT. However, before they left, I asked Randy if they could come back to do a check-up on the main AC unit for my house. Rather than commit to a time and day, Randy said that he would call me on Monday (I even repeated that to him before he left). Well, I never heard back from Randy and by Thursday, 7/12 the refrigerant had leaked from my mini split unit that he repaired to the point where it was no longer cooling and was displaying two separate error messages. So I called Randy's number at 5:30PM that afternoon and left a message to remind him that I didn't hear back from him on Monday regarding the home AC service and that my mini split was no longer working. My wife also tried calling him on Friday and left a voice mail too, but still we haven't had the simple courtesy of a return phone call. It cost me $360 to have Randy and Joel repair the mini split unit. I'm not upset that there is apparently a small leak because that can be expected with the type of repair they did, so I certainly don't hold them responsible for that. But it sure would have been nice to get a return phone call and to possibly schedule a time to come back to look at the unit and to provide the service to my home AC that we had talked about. So at this point I made the decision that we are not going to waste any more time on Don Glenn - it's a "one and done". That's the BAD part. They have lost my business (and apparently they don't care) along with the referrals that I would have surely given to my neighbors and friends. I went onto you tube and studied up on my AC skills, then ordered my own R410 refrigerant and gauges, will pick up a torch and solder today....another $200 spent on top of the $360 I paid to Don Glenn. So I now have $560 into a mini split that cost me $900 brand new and hope to fix this myself. Thanks a lot Randy! Please do yourself a favor and hire an answering service if you aren't able to call customers back yourself. Remember the golden rule is that customers are #1. read more

Randy came right away. He assessed our situation without charge. He was thorough and friendly. At first look, it seemed we needed a new air conditioning unit, which he estimated would cost more than $8,000. The problem was the unit was sending condensation into our ducts, which was creating mold in the walls. He wanted to run the air for an hour or so to see what would happen. However, it was winter time and a very cold day. He returned on a warmer day a second time with two assistants, spent an hour and a half checking the whole system. He discovered that by simply removing an extra filter (which was erroneously left by the original installer), the problem would be solved. He charged us $365 for the two visits and time. He could have easily deceived us and made his $8,000. We were so impressed, we had to go straight to yelp to give this guy a plug. Most air guys are slimy and deceitful. We had the opposite experience with Randy. read more

We just purchased a church and our AC was not functional. Randy and Joel identified the root cause of our issue and as a result, saved us thousands of dollars. They were honest, kind and hardworking. I would highly recommend them to family and friends. Our church is blessed to have worked with them and we pray that they will be blessed for their good works. Keep up the great work!! read more

Excellent service, very thorough, fast and extremely knowledgeable. Reasonably priced to boot. I called them after a horrible experience with another heating company, what a difference..!! These guys really know their stuff. Highly recommended... read more
