Cosmos Heating & Cooling Co

I was interested in pricing HVAC maintenance contracts for my home (using a heat pump AC and furnace heat). I contacted Cosmos for more information. A representative contacted me very promptly, gave me some general information, and scheduled a time for a technician to come and review my system and provide more contract details. I purchased a semi-annual maintenance contract which I deemed to be fairly priced and worth the cost. The technicians were prompt, courteous, and very professional.

He popped in, saw the water drops coming from the HVAC vent, went into the attic with his helper, emerged soon after to report the air handler was not the culprit; it could only be a tiny leak coming from the bathroom above the kitchen. Predisposed to believe it was the ancient air handler that was failing and allowing water to somehow drip into the duct work, I was surprised but relieved. What surprised me most was his invoice. With no explanation, he delivered me an invoice for $100. I presume it was his minimum charge. Neither he or his office the day before told me there would be a charge just for assessing the problem. Had I been aware of it, I would have approached another vendor. Nice guy who uses a not nice business practice.

As on other occasions that I've used Cosmos, the service was excellent. Gus and his assistant got my (old) oil burning, hot-water-boiler furnace up and running again. They got to my home when promised, diagnosed the problem and fixed it quickly. It turned out to be the element that creates the spark that fires the oil, and cleaning the nozzle from which the oil sprays. They also checked the general settings and adjusted the furnace so that it operated more efficiently. In addition to excellent work, Gus is just such a pleasure with whom to deal. He's the kind of man you want to go have a beer with. I highly recommend Cosmos and, as I've done in the past, will continue to call them for servicing my furnace and my A/C unit.

I received quotes from three highly rated providers on Angie's List. One was Cosmos. I liked Cosmos b/c it is a small, family business and very close to my home. Each of the three quotes included a budget A/C system and the next step up in cost and efficiency. I decided to go w/the "up to SEER 16" system. Cosmos' quote was a few hundred dollars more but they agreed to match the price quoted for the exact same Carrier 24ACC6 system by a competitor. Cosmos' Gus and George (father and son) and a worker arrived on time. They swapped out the old system and installed the new one smoothly. They were careful of our home and cleaned up all of their mess. The new system is far superior to our old one. I would recommend COSMOS to others because Gus puts customer satisfaction before profit and is willing to bend over backwards to meet the very high expectations his Angie's List reputation engenders. Notes: 1. Walking by I noticed that the installed v-shaped coil had a number of bent heat transfer fins. It looked like a wrench had been dropped in it. The worker was near and I asked. He said, not to worry, that they would straighten them out; but then he attached the coil to air ducts without fixing them. I complained to Gus about this and another, possibly cosmetic, problem. Gus immediately said he would fix things to our satisfaction. He instructed his son, George, to remove an already installed piece to gain access to the coil so that the bent portions could be combed straight and he ordered a special flexible connector to address our other concern. 2. After all the work and clean up was done, I noticed that two largish holes in the sheet metal vent leading to the air handler had not been patched. I believe these holes were part of a humidity monitoring system that was removed with the old system. It was a simple matter for George get the supplies back out of his truck to patch the holes. 3. While Gus worked inside installing the coil, George was outside installing the compressor. When I went outside to look at it, I noticed that it overhung the pad on all sides. George ramarked that this 32x32 pad was the size recommended by Carrier. The AC was stable and it was aesthetically pleasing not to see the pad; however, I was accustomed to a larger pad to to help provide a buffer for the lawn mower. When I expressed this concern, Gus quickly dispatched George to fetch a 36x36 pad.

This was the second time we used Cosmos and they are great. Gus is not only knowledgeable and helpful, but also kind and fair. He replaced our home humidifier, explained why it's so important in this area, and gave us some tips for its use. He also let us know about some products we might think about in the future, knowing that we have 3 young children. Although not part of fixing our humidifier, he also took the time to check out our gas fireplace and show me how to use it (it's old and wasn't working properly and we just moved into our house). I definitely recommend.

Biggest waste of $100! I contacted several vendors for estimates on either fixing my HVAC or getting an estimate on a new one. Cosmos was unable to fix my HVAC, not even temporarily, but another vendor as able to do it. I was told that I just needed a new system, which I already suspected, but was reluctant to do so based on cost. I really just needed my HVAC to run for a little bit longer. I was simply given a quote for a new HVAC, no measurements were taken, the service guy didn't offer any options for me, in terms of longevity of my existing system, or in terms of brands of a new HVAC. Cosmos was one of the first people to give me an estimate so I really didn't know any better at the time. Other heating and cooling companies came in and gave me a fantastic estimates, talked about types of units and brands, took some pictures, and temporarily fixed my unit while I make a decision on replacing the HVAC. After I had this comparison, I realized that Cosmos didn't even come close. I did not end up replacing an HVAC with Cosmos so I'm not sure if his ESTIMATE is even accurate. I did follow up later to ask if his price includes labor and taxes, which he said it did, but his quote was so much lower than everyone else's so I'm actually in disbelief. Overall, it mattered more to me to get my unit fixed immediately so that I could get heat.

It turned out fine. They did a nice job. It was pretty soon. It went very smoothly. The young man who came and did the service was very polite and professional. There were no problems.

I found them on Angie’s List. We paid for the air conditioner and then we found that there was a leak in the line. So we had to get him back again to change the line, for which he charge us more. Then our furnace wasn’t working and he told us that there was a problem and he charged us to fix it. We called him back and he told us that we needed a new furnace. So, we had to buy a new furnace. There was some leaking from the furnace because of condensation. We called and he hasn’t returned the call or called back. It is fine if the owner is here but he is trying to get his son into the business, and his sun is really bad. So it depends on who comes. If he comes, it is okay, but if the son comes, then it is a disaster.

Gus and George did an awesome job. Gave me a free estimate that was really competitive and a couple weeks later installed new ductwork in my basement. Great communication via email and great availability for work. Highly recommended

Heat up stairs not working. Scheduled service and they came as scheduled. Very professional. Pinpointed the problem within 10 minutes and fixed. Heat working. I used them about a year ago when I had to replace my AC compressor unit. They provided the best price and did great service. In fact, they came out on Saturday and installed the new AC compressor and there was no upcharge for the weekend service. They are my Heating and AC go to guys! Highly recommend

They come out on a holiday weekend to fix the unit. A week later I had to call them again to fix the unit. They fixed the unit at first but I don't think found the true cause for the problem at first, the owners son came out and fixed it again. I felt I was overcharged in this situation because of needing two trips but they got the job done and came out when other people couldn't.

Excellent. He found that the thermostat was not working properly and repaired it.

We're quite satisfied with the heating system and they did everything they promised. However, the filter was a special one, so we have to go back to the company to get replacements which costs a little bit more.

I will not recommend them because they are a worst company. They are liars. They lie on the pricing and they would not show up when they say they will. When you call them for problems, they treat you like crap.

They identified a problem with the H.S.I. being burned out. They replaced the flame sensor, reset the control board and inspected other parts. They arrived on time and very efficient.

It went well. Scheduled on 28 May and completed 2 June. I immediately hired Gus for another job locally. BTW the office moved to Lorton.

Everything went fine. They were professional and on time. I would recommend them to others.

It went very well. I am pregnant and due any day, and was particularly concerned about the issue that came up in the home inspection and getting it looked at asap. He came the same day I called (today), assessed the issue and made potential recommendations; he also assured me that the issue was not dangerous or urgent. I will definitely call when I have more HVAC needs.

Very friendly & responsive on phone. Called at 5pm on a Saturday, they said they'd be here in 90min. After hour diagnosis fee is $200 ($100 is usual). They will provide a ladder for rooftop units (max height is 26'). Cancelled appointment due to conflict on my end, no services provided.

Have used this company for several years now and am very impressed with the professionalism, punctuality and service. So nice to use a company you can trust.

My air conditioner had been working but one morning it did not turn on. Based on Angie's List reviews, I called Cosmos at 7:30 in the morning and also sent an email via their web site. My call was returned within an hour and a service call was scheduled for between noon and 1:00 p.m. the same day. The price was explained to me up front. Later that morning they called to say that they could come earlier. I told them I might be on a business call when they arrived, and we agreed that they would do what they could outside the house until I was off my call. When I got off the call, I turned on the air conditioner. Within minutes they diagnosed the problem: the wrong type of fuse had been installed in my air conditioner fuse box when I had had it replaced recently by an electrician. While they had been at my house for well over an hour, they only charged me for coming to the house, i.e., their minimum charge, and for the fuses. I had feared that I was going to have pay for a major repair, so I was very happy that I had found such honest professionals. Two people came to the house, one of whom was the owner's son, who was the lead person on the job.

Cosmos is family owned. George, the owner's son came out and inspected our unit. He was at our home when we expected him - he helped me finish clearing out the closet so he could get to the unit and proceeded to inspect and service our system to get ready for the hot summer we're in now. I've used Gus and George for several years now and really trust them to recommend what's needed to keep us comfortable without suggesting more than is required to pad their profits. As a matter of fact, Gus let me know that Virginia Power is offering rebates for getting your heat pump system serviced. Since we had already done our spring service, we will be able to apply the rebate to our fall maintenance. So he's all about saving us money - how often does a service provider make that his focus?

I had an unusual situation. I needed to find someone quickly to repair my neighbor's AC that broke down because they have 2 cats with health issues. Since I was checking in and feeding them each evening I was very concerned for their well being and also the house was getting very warm inside. I quickly checked on Angie's List and was impressed by the ratings for Cosmos. When I called Cosmos I spoke to a very nice woman who after I explained my situation told me they would get back to me. Boy did I get lucky when I came across this company. I was so grateful they could come to repair the AC so quickly. George and James arrived a few hours from the time I called the company and after I explained what had happened to the AC they knew immediately where to look to resolve the problem. They work very quietly and are very professional. I was very happy when the air started circulating in the house again and so were the cats. I truly felt very fortunate that I found Cosmos. For the services they performed they were very reasonable. I was also grateful they did not try to sell me anything I did not need. I would recommend them to anyone looking for reliable, professional and quality service for AC. .

" when I called, the company owner answered the call. Was accommodating as to arranging time for service call. Arrived on time. Was able to demonstrate what the problem was with with the AC unit. (Previously Michael and Sons had made service call and 2 different technicians made 2 different diagnosis ---lost my confidence in Michael and sons). "Gus" (the owner), was very professional and knew what he was talking about. Very neat, covered flooring. I would definitely use him again.

These guys are excellent - they came out and serviced my badly failing AC unit on very short notice. Freon is expensive these days, but that's not on them...I would highly recommend them for any HVAC needs - I will use Cosmos again if anything comes up.
