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

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

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!

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.

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

Thank you guys!! My AC stopped working and Around The Clock was the only place that was able to help and have someone come over on the same day that I called. I am extremely thankful for them and Igor was great and very helpful.

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!!!!

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

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

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.

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!
