It went well. Brian explained everything to me and was able and willing to answer all my questions.
Description of Work: A few weeks before they came to check our Air/C and it needed frion. They put frion and then put dye in to check for leaks. This visit they did a diagnostic and found no leaks.

Ms. [Member Name Removed], thank you for your recent Angie's list review. Good to hear that you have no leaks in your cooling system. It is unfortunate that we have to do this in a two step process but time is need for the dye to circulate entirely through your system to get an accurate reading. Gillian Collins

I called One Hour Air Conditioning & Heating on Saturday morning July-1-2017, explaining that my A/C system was not cooling properly. They said a technician could come to the house Sunday July-2. The technician was very nice, professional, and fixed the problem.

I told him if he had to come back again I hope it's covered. I paid him $265 and he didn't find anything. He had a hard time getting to the coils. So it might be back in there somewhere. I don't know if there's anything that would move the dial up necessarily. I can't think of anything. He communicated and told me what was going on. It took a couple hours.

It is okay. I need to have them come back again because I hear some noises in my heating unit and want to make sure everything is functioning properly. We need a service too. We did a contract with them, so we get two visits a year and discounts on service throughout the year. They make an effort to be there as soon as possible. The only problem with them is that each time a different technician comes out and they all have different things to say. Sometimes that is confusing you don't know what is going on. There was one person. They are on-time. They come in when an issue comes up. You don't have to wait three days. It is just that reliability issue that is important. They left the area fairly clean.
Description of Work: The heat was not bringing it up to the temperature. They said that the filters had been misplaced, so they placed them back where they were supposed to be.

It worked out fine, the only thing that seemed to not go as expected is the girl called sold me on a service plan and she said I would get some kind of discount on that particular day of service, but when the guy came out and fixed it I didn't see any discount. It wasn't something I could really take up with the person because he seemed like he was a contractor, I'm not sure though. Other than that, it worked fine. He completed the work the day I called or the next day. This was for my rental home, and I worked thru the tenant and they called me to say everything went ok. I think it took about an hour. I didn't hear any complaints about the cleanliness. He got the thing working well, and educated the tenant a little bit on, he was trying to manually do the thermostat, and he educated the tenant on that.

They wanted to charge me for more and I said no. They tried to up sell. I don't really feel very comfortable being up sold. What's really weird is, after he came to do the multi point inspection, my air conditioning it's getting, how should I say. See what happens is I bought a big deal and wanted to have an inspection on my air conditioning unit before the summer is getting hotter. So this guy came and he did the multi point inspection and he tried to sell something to me, I said no. Then 15 minutes later my air conditioning stopped working. So basically it just blows wind, It's not cold wind. Luckily my air conditioning unit was still under warranty. I called the warranty company and they sent someone here to fix that. Honestly I don't know if his quality is good or bad. He goes over this with me and he shows me this report, like what has to be fixed. I'm not really impressed but not bad. I remember he was here on time. I feel he was under pressure to sell me something. I made it clear that I wasn't trying to buy something so you don't have to tell me that and he stopped saying that anymore.
Description of Work: They did a 20 point air conditioning tune up.

The initially misdiagnosed the problem with my furnace. The diagnosis was my inducer motor was clogged with dead wasps that had come in through the flue. They recommended a pest service to take care of the problem, so I contacted a chimney sweep and also pest service who inspected the flue and vent and cleaned everything up. By cleaning up the motor, the furnace ended up working again. The motor and fan ended up working fine after the wasps were cleaned out. The furnace company came back 3 days later with the replacement part and realized it wasn't needed so they credited me back the fee. I just paid their $49 service fee.

The company is very nice of accomodating my work schedule. The engineer is very knowledgeable and on time. After some troubleshooting the HVAC heating issue, he directed me the problem and showed me the cost of repair. Since the device is still under warranty, I did not go forward for the repair. The engineer was placing back to original setup, and I was able to fix it with calling the manufacturer the day after.
