The staff both in the office and techs are awesome and helpful. They were able to come out same day and repair our AC unit which was a life saver mid June in the valley.

You had your person come to my house to put freon in my A/C unit. Nothing else was checked and he had to come back to give me my filter. I did not use my A/C until the other day and it is not working at all. I paid your company over $500.00 and my air conditioning does not work. He did not check the fuses and he did not come into my unit to check the unit inside only the unit that is on the roof top and he said he put freon and charged me for the freon.

He said I had a slow leak. I did not have freon put in my air conditioner since 2007 so it did not have a slow leak. Had they ever thought it was the fuses you put in my A/C 2019 could be faulty? I am a senior citizen and it is hotter than hell in my unit. To find out I paid your company over $500.00 two months ago and now to find out my air conditioning is not working is not sitting well with me at all.

I would like to know how you will rectify this with me? You called this morning and lied on the phone you talked over me and you said I paid for maintance but I never received any maintain. You said I was not on the roof top with Art that is not true I was on the roof top with Art. You wanted to charge me again to come out to correct your mistakes.

That is poor customer relations. I would never use this company again. They are liars and thieves. They said they had me scheduled for maintaince in October of this year. Why didn't you have me scheduled for Maintaince between 2019 and April, 2022 when I called you for maintance and my air conditioning was working just fine then. I noticed many others have complained as well they try to should you good reviews but what about all the bad reviews from customers? I have already asked for my money back. It seems you have over charged other customers as well.

We have used Around the Clock for four years. When we first moved in, we got them to install Nest thermostat and do an HVAC system checkup under an LADWP program. Since then, we have them come back every year to replace AC vent filters before summer and tune up the furnace before winter. The price is good, the service technicians are excellent, and scheduling has always been responsive.

Great service overall! We shopped around at a few places but Around the Clock had the best price and service quality. Igor was very attentive, honest, and patient. Communication with the office was prompt and thorough. Installation by Ernie, Yonathan, and David were done in a very quick and professional manner despite our old house being a bit difficult to work with. Every person we interacted with has been friendly and helpful! A+!

This company did very good job to removed old Heating system and installed a new Lenox HVAC system in two working days. We had installation technicians Ernie, Jonathan & David who had very well knowledgeable about the job and did very good works on all around this job. I do recommend this company to neighbors who may need a new HVAC system.

Horrible service, horrible staff. Inconsistent pricing, and the parts that they do install are defective. I would stay clear away from this company.

Out of all the HVAC replacement quotes I received (including Home Depot), the most reasonable and timely. Did not have to negotiate much because they are competitive. Consultant and workers were super friendly and arrived on time each day. They also were very knowledgeable and did an honest job, finishing on time and taking photos of my ductwork. Would use them again.

Jeff sold, and Ernie and Jonathan replaced our entire heating and air conditioning system yesterday. They did a fabulous job. They were careful to cover our home with drop cloths and left the job neat and clean. Ernie in particular went out of his way to explain everything he was doing and to assure I was satisfied at every step of the job. The installation is very well organized and neater than the system that was replaced. I would definitely recommend them if you need a new HVAC system.

Called early in the morning for an AC/heat repair. Was booked on the spot, same day. Technician arrived in less than 4 hrs. Technician explained everything he was doing every step of the way. Same day fix! Very reasonably priced. I had a great experience with All around the clock

Exceptional service. Showed up quickly and fixed the problem quickly. I had a home warranty repair service come out before they did. They took days to show up and when they did they said they needed to order a special part. I tried calling for updates and it was one excuse after another [ when they bothered to pick up the phone ]. After 5 weeks of dealing with Platinum, I canceled my home warranty company and called Around the Clock. In 20 minutes the problem was fixed.

I removed my one-star rating from November because Alex (owner/supervisor) went above and beyond to correct any problems I was experiencing. His company's reputation matters to him. He sent his top-notch crew and they installed dampers which evened the flow and made it much quieter. The sound was loud and whooshing as well as 3 minutes of cool air blowing before the heat would come on.

They corrected all. Yes, they wore masks and booties. The only reason I give 4 stars is that it took a year to correct any problems. Different small problems occurred, like a humming noise during the use of air conditioning, which needed to be addressed but these weren't known to deal with until that season's needs came about. Once Alex was made aware all issues got attention and addressed.

The Around the Clock rep was on time, professional and performed good work. I hope I won't need HVAC assistance anytime soon, but if I do I would not hesitate to work with them again. Service: A/C system repair

Our refrigerator was leaking, and we were preparing to leave town. Around the Clock sent a technician that same day. He came within the stated time period, diagnosed the problem immediately, and fixed it with dispatch. Great job -- I highly recommend Around the Clock! A friend recommended the company to me, and her father recommended it to her. I can't wait to recommend Around the Clock to someone else.

After my uncle recently spent nearly $400 with a wrong diagnostics from one Heating & A/C company, I decided to visit www.costco.com and type Lennox to search for the page at https://www.costco.com/lennox-heating-air-conditioning.html. Then, click "Request A Consultation" botton to fill out a form in minutes in the evening. Next day, I received a call for a next day on-site inspection and consultation.

Within 30 minutes, my uncle received an official quote. Within less than 24 hours, my uncle called the vendor to sign the contract after knowing that he will receive a 10% Costco Shop Card, a 2% additional rebate as a Costco Exec. Member and 2% cash rebate from the CitiBank Visa card. Per the Costco authorized Lennox HVAC dealer, the installation will take place with one week or less. Indeed, Around the Clock Heating & A/C sent two people within 72 hours to install a new Lennox EL-180NS furnace within five hours with a 100% satisfaction. Gerenally speaking, most Costco's customers should have a piece of mind because each Costco dealer must adhere to its Premier Installation standards via Costco's thorough set of guidelines.

Leon has worked in my apt before reinstalling a new thermostat His recent visit was to inspect my older model gas furnace for co2 exposure. He's very knowledgeable & made good suggestions for vent cleaning of soot, plus the installation of a newer & more efficient source of heat. His charge was modest at $125. At Around the Clock, the employees are helpful & polite. 2 thumbs up definitely!

We've had issues with our heater intermittently working. I used to have American Home Shield and First American Warranty - do NOT get home warranty because it's not worth it. Multiple repair folks have come out and each time, they tell me there's nothing wrong. Finally today, the heater stopped working completely. Never turned back on and of course, weather in LA right. now is cold!

Literally shivering in my home with the temperature showing 59 degrees (YES INSIDE), I called Around the Clock and they were able to schedule me right away and a technician arrived within the hour. Can I just say that this technician was the first one to actually SOLVE and DIAGNOSE our problem. He methodically explained everything, our options, the possibilities.

And he fixed the issue on the spot and we had a plan forward in the event the intermittent issue pops up again. I mean, for the first time, I felt like we actually got a technician who knew what he was doing! Definitely recommend this company! Yes, they charge for a service call but if you do the repair, that charge is waived. I've put them on speed dial now.

Around the clock charged me $125 to come and check out our AC. Someone came in pretty rude, went up in the attic, stayed less thank 2min in there and quoted $6500 for repairs. Quote was literally 3 lines of text. $125 for no diagnostic, he didn't even go around the AC to check the problem, just stared at it and came up with $6500 to replace an evaporator coil.

As a new home owner I am so tired of all those scammers at there that charge money to do absolutely nothing and then give you an insanely priced quote. I did tons of research, checked on AC professionals forums. The advice they gave me : do not let those people inside your house again. I had 4 companies total come in and give me estimates, had the work done for $2000, and it was done correctly.

Their free diagnosis and estimate detailed all that was wrong, g with the AC and individual prices for parts. They included labor also. When I called the owner of Arpund the clock he literally acknowledged that's how they make money. By scamming people and over charging, if they sign and accept then it's on them. What a s Amy way to do business. If you call this company, do your research you'll probably find more ethical people.

Abdiel was called after 1AM on a Sunday morning and agreed to come out at 8:00AM the next morning. He was there promptly. He had to go chase a part on Sunday and found a place open and literally had me back up and running by 1:00PM. Great service and fair pricing. Highly recommended these guys!

My tenant notified me that there was and burning odor Coming from the AC unit. Someone came out to check my AC just to tell me that they're not sure why there's a burning smell after running the AC for a few hours, but maybe I should change my motor or whole AC unit. He said he checked everything and couldn't find any issues, but he was guessing.

He still charged me $95 for no proper diagnosis, They said I'd have to call someone else because they don't do those services. Such a waste, I definitely don't recommend this place. Oh and not to mention since the guy was only there for a minute he said he would only charge me $70 for coming by, he then changed his mind right away and said $95; so ridiculous

Expensive and don't stand behind their work. $125 service call is the highest out there----there are plenty other reputable HVAC companies charging only $85-95. They charged me $125, did some diagnostics, when my A/C still didn't work despite following their recommendations they wanted to charge another $125 to come out and re-do the diagnostics. CALL SOMEONE ELSE!

The DWP website lists this company as servicing area code 90046, which is Hollywood, for the "optimization program." On calling them, they said they don't service 90046. My reaction: 1. Why would you hire a company that is so sloppy in this regard. I'm sure the DWP didn't "make up" that they are in the program for Hollywood. This company put that in the DWP website. 2. They say their address is North Hollywood. If that is true (there's so much scamming these days), how could Hollywood be "out of their area."

During this current heatwave in LA, my parents A/C unit up and died. My mother called in the late morning on a Thursday after looking at the Yelp reviews. Someone immediately picked up and what first was notable was that they tried to troubleshoot over the phone because no one was (understandably) available for a same day service. They attempted to help off site but ultimately needed to send someone out within 24 hours of that call. Wow! Quoted a time between 9-12, Leon arrived at approximately 10am.

He needed to check out the filter which is in the basement/crawl space underneath a closet (I know it's weird). Leon was helping my mother move the items in the closet. I can imagine a scenario where many would just stand there, but Leon pitched in to get the job done! Turned out a malfunctioning motor caused the A/C to overheat. Leon left to get the part and was gone less than an hour.

Everything was completed by the time the original quote time had passed. The quote we were given at the beginning of the job turned out to be more than we actually had to pay for. I appreciate an honest company. Upon completion of the service we received an items bill via email. Would definitely recommend this company.

Why is it called "around the clock" if it's closed? And they don't return calls for weeks at a time. I think they need to rethink their business name and their business model.

Short version: World Class service and respect for customers. Longer version: Listen. any time your AC stops working, it is a crappy situation. ESPECIALLY in the San Fernando Valley. Mine died in a heatwave and ended up needing several parts replaced. ATC in general and Igor specifically were quick, kind, professional, and no nonsense. They didn't sugarcoat anything, but managed to keep costs affordable considering the issue and parts. I can't recommend them highly enough.

Igor came to look at my a/c. He discovered that it was most likely a warranty issue, so he told me to call the manufacturer and have the work done through a warranty claim to save me money. He didn't even charge me for the visit. Thanks so much! Will definitely use them in the future for non-warranty related issues!

This business is phenomenal. From the first phone call the entire staff was very helpful and answered all of my questions. they were able to come that day and despite me not being able to meet them they were so considerate and waited and then came back the nest day. They did a great job fixing the heater and didn't even try to sell me on anything or charge extra.

They called me with updated and the invoice was immediately sent to me. They communicated with me throughout the entire process and everyone was extremely friendly and the cost was very fair! Great business and will definitely use again!

Of course it was 115 in Burbank when our 15 year old HVAC compressor shut down. We called Around the clock from a google search. They came right out and rebuilt the compressor with new energy efficient components. When the tech turned it on it was so quiet I wasn't sure it was even spinning. The cost was reasonable and our electric bill went down $200 and the house was very cool. I highly recommend!

When my AC petered out late in the evening during a record heatwave over a holiday evening, I seriously thought I was screwed. But this company was so fantastic! A technician was here within a couple hours of my call, on Labor Day, even earlier than the appointment. He got everything fixed up, and now I'm laying under the AC register soaking in the cool air.

Another thing to note. I've called them before, months ago, when my AC started blowing warm air during a heatwave. They told me to turn it off and reset my circuit breaker, that it would fix the problem most of the time. Maybe that's common sense to a lot of people, but as a newer home owner, I didn't know. And it DID fix the problem. That kind of honesty, when they could easily have come here, charged me, and flipped it themselves, was why I bookmarked them to call next time. And I'm so glad I did.

My ac broke on a day that was 96 degrees outside. Almost that hot in the house. I called around the clock and they sent a technician within an hour. As an older person, I was delighted that he wore a mask! He replaced the broken compressor and was done in 15 minutes. Excellent service and kind people. Call them first! Service: AC repair

Igor was punctual and very respectful of Covid-19 safety wearing mask and gloves. After diagnosing our issue he took the time to explain it in detail so we understood exactly what was happening and answered all of our questions. He suggested the most sensible and cost effective way to go so that we didn't spend more than we needed to, and he worked quickly and efficiently. Good experience; would use them again.

Everything about this company is excellent. They are friendly and do very good work. The person who came out to analyze and fix the old furnace explained exactly what he had to do, made another appointment, then promptly fixed the furnace. I recommend Around the Clock wholeheartedly.

The air conditioning in our home has always been working pretty well, however my entire family lately had noticed that the air has not been blowing as cold anymore and definitely not even close to what the temperature was set to. We set it to the lowest setting and it felt like it was blowing at like 80 degrees. Well turns out that not only it felt like 80 degrees, but it actually was blowing hot air and not cold air.

A good friend recommended me to use Around the clock AC and heating and wow am I impressed by this company. They seriously do work around the clock and they fit me in their busy schedule the very next day. They diagnosed our ac system and they realized that their was freon leaking from the condenser. They put some special dye and wore these special goggles to spot out the freon leak and they showed me as well.

They had the parts in stock so they got our AC up and running the same day. I could pretty much make my house like Antarctica at this point. Well I've always loved polar bears.so.jk! But I do love polar bears haha. Overall I am very pleased at the efficiency, honestly and fair pricing of Around the clock AC and hearing!

This company is absolutely perfect in every respect. We primarily use them 4r AC issues. We have also used them to repair some of our larger appliances. They are always on time, they listen to the problem and then they fix it. Never once have we had to call them back a second time for the same issue. They are trustworthy, and extremely professional in everything they do. I highly recommend them without hesitation.

Each person I dealt with was amazing! I especially liked that my salesperson provided a detailed easy to read estimate and was available for additional questions before I purchased the product, and afterward as well. The installers were prompt, courteous, and cleaned up so nicely after the installation. I really appreciated the extra effort they made after a long hot day! Thank you!

Around the Clock has become my "go to" for appliance repair. They were recommended by my contractor when we were remodeling. Over the years I've had them fix my washer, subzero freezer and most recently my air conditioner. They are quick to schedule an appointment and show up on time. I've always been pleasantly surprised at the reasonable pricing and the lack of pressure to upgrade or do more than needs to be done. Alex is great should you get a choice of repairman.

Several years ago Around the Clock installed a heating and air conditioning unit for my entire house. They were fast, efficient, reasonably priced and gave me a good unit that is trouble free. They are responsible and thorough in their maintenance. And the staff is personable and polite. I'm quite happy with my unit and with Around the Clock. Glad to review them and recommend them.
