It went pretty well. Had to callthem back 2 or 3 times to fix some things that were nor wired exacrly right. he people that came back were prompt and very knowledgeable and efficient. Day or night when I called they were available. P. S Another recent experience with this co. Came out and diagnosed a power line fuse for three phase system was out. Spent about 30 min at my house andcharged $183.00. I complained but got no satisfaction. Will not use them again. My trust in them is shattered.

Response from A J Warren Service Co
[removed member name] called us out on a Friday night with his system not cooling. We promptly came out and found that system did not have proper high voltage supply to it. Most companies would leave it at that and tell the customer to call an electrician. Our techs are some of the best in the city and know that there is a circuit breaker up on top of the power pole. He found where the power for the house was coming from. He then was able to see that this breaker was indeed tripped. He then informed [removed member name]that he should call CenterPoint and that they would fix the problem at know charge to him. This saved [removed member name] the money an electrician would have charged him to tell him to call CenterPoint once the electrician found that the problem was at the pole. We just chaged for a trip charge and a minor miscellaneous repair charge. Our tech with travel time to the call, had 1.33 hours in it. I tried to explain all of this to [removed member name]. He thought we should only charge him the trip charge. We can not stay in business unless we charge for the work we do. We can not warrant CenterPoint's power.

I had problems with an AC and I had a company come out, but they told me that I needed a whole new AC because I was under warranty. I called AJ Warren and they just told me that I needed some freon. I also called them another time and they helped me over the phone.
Description of Work: A J Warren Service Co signed me up for a yearly contract. I had a clogged air line the last time.

They were GREAT! Always showed up on time, very friendly and really knowledgeable. We no longer have extreme heat on our downstairs and the system is working very well. The company who installed it initially had about 30 service visits to the house and no solutions, and AJ Warren managed to get everything going very quickly!! THANKS!
Description of Work: Installed a damper system to supplement our one-unit AC system. Problem was that downstairs did not cool properly despite the system being relatively new (installed 2 years ago by Church Service Company).

This has all made a great difference and I am very happy. The bathrooms are now warm when the weather's cold and the bedroom no longer has stale hot or cold air. Before I also had what I thought was dust everywhere, but it was actually the old ductwork disintegrating - I could see pieces of insulation in the vent grill and wondered how that was happening. Unhealthy, I'm sure. My house is small and the ductwork didn't have very long runs. It took about five or six hours. So, I wasn't a big customer, and I'd already had the rest of the system replaced, but I was treated very nicely. The employees were very neat and careful with their work and also very pleasant. I actually found this company before I joined Angies List - they were at the Berry Center home show when I was on the hunt for another AC company as I hadn't been happy with the three others I'd used. Also, one of them uses the same dentist I do (had on his uniform) and he behaved very nicely when the dentist had been running late. The price for this job was considerably less than what another had quoted me a couple of years earlier and I know the quality of the work was way better than the other guys would have done. I'm glad I found this company.
Description of Work: A J Warren replaced the ductwork in my home. They also added another return air in my master bedroom and increased the size of the ductwork to the bathrooms.

I'd had problems with this before (and another neighbor has too) as the drain line that connects in the attic would overflow and make a huge mess. But the gentleman from A J Warren explained what was wrong and told me how to fix it with a PVC plumbing fitting that they normally didn't carry on their trucks. (The other guys would say: see you again soon.) The repeated charges to fix it temporarily weren't very high, but it was incredibly aggravating wondering when it would happen again and then moving furniture and cleaning up the soaked mess. So this company's man cleaned it out, cleaned out the backup and other lines, and told me how to fix it easily so he wouldn't be coming back at least once each summer. I think that's very excellent.
Description of Work: Worked on my AC drain line which was plugged up and getting ready to soak my house again.

Description of Work: They put in a new hot water heater. They had to bring it all up to code with the venting system. They did an emergency plumbing service where I had a link in the ceiling.

I asked to have the existing hard-pipe ducts replaced because they were leaking badly, crushed in places, and poorly insulated. Everyone else recommended installing new flexible ducts, but John told me that I should not replace a hard-pipe system if it is already installed but rather repair it. He said that hard pipe is better quality and has less friction than flexible, so I should not get rid of it. While doing the estimate, John temporarily fixed a broken wye, opened a couple closed dampers, and was the only estimator to crawl all the way to the back utility room to see why it was getting no air. He was also the only estimator who didn't try to sell me a new air conditioner. The above items are what won them the business. The crew was friendly, worked quickly, polite, and very professional. The first day they replaced the crushed and broken ducts and sealed them with mastic. They installed a new plenum and moved the duct exits farther to the back of the plenum so that the air would mix better. After the city inspector came the morning of the second day, they wrapped the ducts in R-8 insulation. The workers showed me what they were doing each step of the way. They cleaned up after themselves. They even fixed my admittedly somewhat-rickety attic ladder for free. At the end, they balanced the system and checked temperatures at the ceiling registers. I have only two small gripes. First, the cost of the permit was not included in the estimate, and it wasn't stated that it would be extra. John said this was an oversight, and they had treated me well in everything else, so I trusted him on this one. Second, I thought the air balancing at the end would be a little more sophisticated - the workers adjusted dampers in the attic while I stood under the register to tell them if the room was getting enough air. Then they checked the temperatures and re-adjusted the dampers until they got it the way I wanted it. But it's kind of hard to tell if it's actually enough air or not without some kind of quantitative measurement. They did promise to come back and adjust it for free if it's not right once the cooling season starts. I also think they are more expensive than some others, but the work was definitely high quality and I felt that they were really trying to do a good job for me and not just sell me an expensive air conditioner or services. Overall I would highly recommend them. They will try to provide what is best for you and not necessarily what is most expensive. They will be my permanent HVAC contractor now.

They arrived as scheduled, put booties on to protect carpet and floors. Everything went well until it came time to pay. They refused to accept the coupon. They made some excuse about it being for two checks in one calendar year (Spring and Fall of the same year). This was the winter check. I told the lady who set up the appointment that I would use the coupon that they sent to me. If both check-ups had to be used for the same year, why did they mail the coupons in the Fall? They did finally honor the coupon, but l had to call the owner of he company. After several minutes he reluctantly agreed to honor the coupon. I have not decided whether I will call them for the Spring check.
Description of Work: A. J. Warren had been recommended to me and I also received a $75 coupon in the mail a few months before I scheduled the appointment. A. J. Warren performed an annual check-up on our heating unit. .

Response from A J Warren Service Co
We tried to explain to member that the flyer she presented as a $75 coupon was not a coupon. It is on our seasonal mailers we send out. It is an advertisement explaining how customers can earn a $75 Reward Certificate. If member had one of the Reward Certificates there would have been no problem. Here is the exact copy in the mailer that she presented: "A. J. Warren Service Co. will issue you, our valued customer, a "good as green money" certificate towards the payment of any service work or equipment purchase. You will receive one $75 Reward Certificate for every new customer you send us who does at least $75 worth of business with us and gives us your name. There is no limit to how many certificates you can earn. If you have never done business with us, please call for service. Refer yourself as a new customer and receive your $75 Reward Certificate to use next time you need service. Call your friends and neighbors and start collecting your rewards today! Certificates not redeemable for cash and are not good with any other offer." Member thought that this ad was a certificate which it is not. She never completed any of the the requirements to get a Reward Certificate. We always do what is right for our customers. We always stand behind our 100% satisfaction garantee.

I bought this house in July 2010. The heating system hadn't been checked because it was summer. I called AJ Warren based on their Angie's List rating. Kyi, the service tech, arrived on time. Very professional in his manner and work. Checked out the heating system. Found the fresh air damper was not operational and had no filter, and the drain pan had no overflow switch. Kyi fixed the fresh air damper and installed a drain overflow switch. I also signed a 1-yr service contract, very reasonable fee. I'll stick with AJ Warren.

Everything went fine in the begining and the quote was for $412.00. The company offered an Angie's List coupon for their $78.00 diagnostic service call which the tech would not honor when it came time to pay the bill. It took me months of phone calls before they sent me a check for the $78.00. If they did not want to give this discount then they should not have offered it. The work they did has held up but I will look for a new contractor when I am ready to get more AC work done.
Description of Work: Replaced condensation lines from air handler unit in the attic, and put in a sensor in the condensation trey so that if the water level rises to the point of over flow it will shut the system down rather than flood.

His $78 refund check was sent on 8/19/10. He called once or twice over about 3 weeks, not months of phone calls. I tried to satisfy the member. We guarrantee all customers satisfaction. We appreciate the member's business. We would love to help him further. I am sure that he would soon realized that he has left one of the best service companies any where.

All the work was done in a timely manner. Very satisfied. This company will be our primary contact for any future HVAC work.
Description of Work: Performed a check of the heating system in preparation of winter. Corrected some discrepancies noted by inspector when purchased home. Added some safety devices that were not installed initially i.e. float switch and surge protector. Mike arrived on time, did his work efficiently. Explain everything he did. I also purchased a year plan from this company for a fall and spring check in 2011. I checked this company out on Angie’s plus they were recommended by my realtor before using. Nice fellow, Mike.

The price was a little high and I thought it was higher than it should have been and was a lot of money for the work. It shouldn't have taken more than 30 minutes for the work. They did identify the problem and fixed it, which I was happy about. They did come the same day I called them. I am going to look somewhere else when I need service because I didn't like the price.

We really wish we could do our work for less money to our customers. At the prices we charge we are lucky to come out with any profit at all at the end of the year. Customers often do not realize how much it costs to run a quality minded service company. The member was quoted the price of the repair before we did the work. I hope he will return to us. There is a saying that goes, "The bitterness of low quality remains long after the sweetness of a low price has been forgotten."

They were right on time and honored my coupon from Angie's list. My only complaint is I asked for a sales rep from the company to call me to discuss buying a new AC unit and I haven't heard from anyone yet.
Description of Work: My air conditioner compressor was making some strange sounds every week or so. AJ Warren's technician came out and inspected the unit and was unable to find anything obvious causing the noise. He tightened up some bolts and I haven't heard the sound since.

They were fabulous. The downstairs unit pretty much stopped. He came out and took a look. He told us that we can buy a cheaper motor but that the lennox motor would be better and gave us the price differential between the two. That was great advice. He immediately told us what was going on and we really appreciated the advice and was fabulous. He fixed problems that we had on going for over six years.

Scheduled a spring A/C checkup. They arrived on time. I am very impressed with the professionalism and knowledge of my technician, Kyi. Very respectful, and took time to put on boot coverings, and used my doorbell before entering my home. He had to do some work on one of my furnaces that was under warranty.Took the time to call manufacturer for details of my service agreement. Checked my units very thoroughly. I definitely will use again. I also spoke with a sales person at thier office. He was also very knowledgable, respectful and professional.

The work performed was excellent. The workers were on time, friendly and courteous. The only problem was that the work was estimated to take 1 day, but ended up taking 2 full days plus a few hours on a third day. They also fixed a few problems at no additional cost on my attic units that were installed by another contractor. I highly recommend A. J. Warren for any A/C work. Although the work was pricey, A. J. Warren was less expensive than from other companies.
Description of Work: A. J. Warren removed the existing attic duct work that was leaking and deteriorating. Designed and installed a new duct system using R8 flexible duct for two units in attic. Duct was hung to provide better access to attic floor for added insulation.
