Recommended Customer Reviews

My Central Air stopped working on Sunday. I called All Systems who works with my insurance. They were prompt in coming out Monday morning. Installed a hard start kit and i was operational again and cool. They were pleasant and informative. Will request their services again. Steve Powers Templeton, Ca.

I would not recommend this company to anybody to do service with. They were contacted through my home warranty program. Took them over 24 hours to set up the appointment. Never showed for the appointment. Never called to say otherwise. My wife called and left him a message to call back they didn't even do that. In the next two days they never called back to reset the appointment up. Then left a text for my wife for the following Monday this is a week later. Called and spoke with Greg, told him my displeasure, he could have cared less, he actually hung up on me told me to call somebody else. I would never allow this company to work for me or even enter my front door of my house.

Liars. Did not finish job or return, told insurance company they were done. Avoid like the plague.
UPDATE: I have now been contacted by Greg Cockerill of All Systems, who doubled down on his lie and blamed the conditions of a warranty instead. It's weird, I called him a liar for saying ""I'll be back tonight"" and then never coming back, and denying having said he would during a later phone call... how he thinks THAT was the warranty's fault is beyond me. Can't fix stupid, I guess.

This company was used by my insurance company to repair my air conditioner in my Arroyo Grande home. There was a hefty surcharge for this service, which I paid to them. I now have a condenser sitting outside my home, not connected and they are not responding to my calls or calls from my insurance company. I am about to call my attorney for advice. I definitely will report this to contractor licensing and BBB.

I wish I could leave less than a one star. These people are running a farce of business. No physical address for the business, only a PO BOX. An answering service that just rattles on the same regardless of the day or time. THEY will never return a phone call. I even called the tech's cell that he gave me. It's the son I think. VOICE mail box if full, so that won't work. Guess I'll also call the BBB to report them. I will likely call the state contractors board to report as well. There are good businesses and bad, this one has shown me it's a bad one that should not be in business. NO CUSTOMER SERVICE whatsoever.

I can't recommend this company enough! The AC went out last night in my vacation rental, in the middle of an unprecedented heat wave, and within less than 24 hours All Systems Heating and Air were at my home replacing the motor and run capacitor. Since it was 112 degrees in Paso Robles yesterday my house guests were overjoyed, as you can imagine, to have such a speedy repair. Oh...and this happened over a holiday weekend!

Greg with All Systems Heating & Air provided the best customer service and work that I have encountered in quite some time. My a/c went out on Saturday June 17th. I contacted my home warranty company. They provided me with the name of a company they contract with. I spoke with that company on Monday and they said it would be a week before I could get an appointment. I was sure that the a/c unit needed freon as this had happened in the past. They still were not able to come any sooner. I called the warranty company back and asked for another referral. They gave All Systems Heating & Air. I called and left a message. This was Monday close to 5pm. I connected with Greg on Tuesday and he came by that evening. He was able to put freon in the unit and diagnose that the unit had a leaking coil. He said he would contact the warranty company to get authorization for a new unit. He followed through and the home warranty company ordered a new unit on Thursday.
Greg offered to replace the heater at a reduced cost at the same time the a/c unit would be replaced which I thought was a very reasonable offer.
The warranty company ordered the unit but I was still waiting on July 20th. The bandaid fix had broke and I had no a/c since the 19th. I spoke with All Systems Heating & Air and they were also still waiting for the unit. They said the warranty company had reordered the unit but they didn't have the details on why or when.
I called the warranty company on Friday the 21st and found out that they had re-ordered the unit on July 14th, a mere 4 weeks after June 17th because the first order had not been delivered. They said the unit had been delivered that day to Bakersfield and then Bakersfield would have to ship it here.
I received a call from Greg on the 26th letting me know they had received the unit and would be able to install it on Saturday. On Saturday he and his crew showed up and worked ALL day in the heat installing the new a/c and heater unit. They were all very courteous and friendly. They worked as a great team and I would welcome them back in my home anytime.
On Monday Greg came by after work and checked the unit to make sure it was operating properly. He said that the registers upstairs were actually reducing the air flow and asked if I wanted a new thermostat. He then adjusted the vents to help improve the air flow. He said that he had a thermostat and could order the new registers.
On Wednesday evening Greg returned and installed the new thermostat and replaced the registers at no charge.
I recommend Greg with All Systems Heating & Air to anyone and everyone I know and people I don't via Yelp. He was prompt and put the customer first. He was knowledgeable, helpful and friendly. He did not try to take advantage of me or the warranty company. If I need anything done with heating, a/c or plumbing I'm going to ask Greg and call All Systems Heating & Air first.
Thank you Greg and All Systems Heating & Air

This company was a vendor for my home warranty company and received my service request for AC repair early Friday afternoon. They were to contact me within 24 hours to set up an appointment, but despite a personal phone call and email, as well as a phone call and message from the warranty company, they did not make any contact. Early Monday afternoon, I got tired of waiting (100° weather on its way), so I called the warranty company. Once again they attempted to contact the company, but no one even answered. Unreliable company that I would urge all to avoid doing business with if at all possible.

No show...twice. This company is obviously not interested in working small jobs or those with home warranties. They simple don't show up if they don't feel like it. Sad. No phone call, no follow-up, just didn't show up (for the second time). Terrible customer service. Beware!

Do not, I repeat DO NOT use this company. They were originally called to our house by our home warranty company. From the start, our new water heater was installed incorrectly (even had to call them out the very next day because we didn't have hot water). Fast forward 2.5 years, and we have a leak. We call them out and they supposedly fix it. Fast forward a few more months and we now have a destroyed living room floor due to water damage from a leaking water heater. We reached back out to All Systems who first denied they did our install, then told us to find a new plumber (no really they wouldn't stand behind their work). After speaking with a few professionals we find out the entire thing was put in incorrectly and was not up to California code. Maybe this isn't their area of expertise, but any company should at least stand behind their work and find a fix. We now had to pay out of pocket for a new install and have to do construction to fix all the damages.
