He was extremely knowledgeable he has given me good industry information and he gave me advice for the future. I do plan on hiring him if some work needs to be done.
Description of Work: Jeff he came out to evaluate my heating and AC conditions it wasn't cooling our master bedroom so he came out to asses the situation, so he came out to look at the furnace and the duct work but whoever lived here before us didn't do proper duct work. He said everything is functioning as good as it can be. If we decided to remodel our kitchen they could at that time run a duct from the furnace to our master bedroom but until then there's nothing really to be done.

The service and professionalism was very exceptional. They explained the problems in layman's terms, which allowed for easy understanding of the problem and decision on replacement of A/C unit. John Cizek and his installation team were very professional and courteous. I felt completely satisfied, and felt no post-purchase anxiety with the investment of a new A/C unit.

First time I worked with them it was for a quote for air cleaning equipment. They were very professional and everything was great, but I decided not to have the work done. I had annual servicing done by Deljo a couple times and everything went smoothly. I had to knock some points off for responsiveness and price because of the time I discovered my heater broke just when the first cold push of winter was coming. I was glad they got out to look at it quickly, but after charging me $89 to see what was wrong I was told they would check if they could get the part and provide a quote which he thought probably end up around 400-500. Nobody got back to me and I waited out the cold weekend without heat. The next week I had to struggle with them to remember me and provide a quote. Finally I just found it easier and faster to order the part for around 150 on the internet with next day delivery and install it myself. Seems good for normal service. If you get anything major done I think they are good and professional, but you better get a couple other estimates to check the pricing. I wouldn't call them for an emergency.
Description of Work: I have had them do annual service in the past and once had an estimate for heater repair done.

Service man arrived promptly. He destroyed half of hydrangea and killed an entire bush. My air conditioners have been in the same place for 3 years and DELJO has serviced them for 2. This time, the service man decided on his own to pull the a/c's out further without seeking an approval and he also chose to service the a/c's while damaging surrounding garden. IF he felt that plants needed to be removed, he should have asked. He didn't mention that he damaged half the garden before he left. I called the service man and he apologized. I asked him to please discuss the matter and get back to me with whatever action will be taken either against the service person or however they think that they can make amends. He has never called back.

Response from Deljo Heating & Cooling
WE DO APOLOGIZE FOR THE DAMAGE TO YOUR FLOWERS AND WE HAVE REFUNDED YOUR MONEY FOR THE INCONVENIENCE. BUT AS YOU CAN SEE BY YOUR PICTURE, THERE IS VERY LITTLE ROOM FOR A PERSON TO WORK ON THE AIR CONDITIONER.

From start to finish, dealing with Deljo was wonderful. When I called for the appointment, I was given the day and a 2 hour time window, right from the start. They called me the day before to confirm, and the service man came within the 2 hour time window. Unbelievable service! He thoroughly evaluated my system, replaced the needed freon, checked all drain tubes and placed a complete written record on the heater for the next service man to see. My air conditioning unit is 19 years old, and the service man gently suggested I get ready to replace it, but did not try to sell me a new unit. Needless to say I will be purchasing the unit from them in the Fall! They are a wonderful company to deal with, and I thank Angie's List for the resource.

They made suggestions and then they did not work. I'm not satisfied with the results from this company but they did not guarantee it would make a difference. UPDATE (6/20/08): They came to my home a few days later and refunded $1200 of the $1575 original payment. I am impressed with their integrity. I have changed the Overall, Quality, and Responsiveness category grades to reflect this recent response.

gas leak repair

We had a very good experience with Deljo. We called several companies mid-morning on a Friday asking for a service call that same day (as we were hosting a large family gathering that Sunday) and Deljo was quick to respond, dispatching a technician (Greg) who arrived within 90 minutes. Even though we made it clear that our main priority was getting the work competed that day, the woman we spoke with still directed us to a $50 discount coupon available on Deljo's website. That was thoughtful. Greg was friendly and thorough, explaining what he was doing and providing an accurate estimate for how long it would take. He also checked with his supervisor on a couple of occasions when he wanted to confirm a procedure, which was reassuring. There was only one avoidable problem with the service call. After the work was done, there was a 30 minute delay while Greg waited for an air compressor to be delivered by a colleague, once People's Gas indicated that we needed to test the repair by pressuring the system prior to their restoring the gas. According to People's Gas, a licensed technician should have known this was the procedure and presumably brought the air compressor. For this reason we are giving them a "B" for quality, because no other demerit seems suitable. Nevertheless, Greg did not charge us for the time he spent waiting for the air compressor, and it arrived quickly. Greg was also very thorough in testing the repair, and making certain that the compressed air testing would not damage our gas-run appliances. As he was leaving, People's Gas arrived to inspect his work and turn on the gas. Even though he had been paid and could have left, Greg remained to make certain that People's Gas approved of his repair and restored gas to our home before he left. Overall, this was an excellent experience. We would call Deljo again with any suitable work, and would recommend them to others.
Description of Work: After People's Gas detected a gas leak coming off our gas meter they shut our gas off. Deljo repaired the leak, pressure tested the repaired pipes as required by People's Gas and stayed until People's Gas restored gas to our home.

After living in my place for 2 years, I decided it might be a good idea to have my Heating and A/C checked out. I called Deljo after looking on Angies list for high rated service providers close to where I live. The women who answered the phone gave me all of the information I needed and their pricing for the services I required. They gave me a 2 hour time window for a date in the future when the weather would be warm enough to check the A/C. Jonathan, the service man, called me before he showed up right in the middle of the two hour time frame they gave me. He was professional, courteous, polite, knowledgeable, and took time to answer all of my questions. If they had found a problem (which the did not) I would have been perfectly comfortable authorizing the work on the spot. I will call Deljo again next year for my service and if I have any issues with my heat or A/C they will have the first opportunity to earn my business.

One of the things I liked about Deljo, was that they worked with me to arrive at a reliable, cost-effective design. Although it did not include the highest tech components, it should provide me with years of dependable operation. I also appreciated the fact that, when given the option of replacing the existing air conditioner at the same time, they said no need, since this could be done at a later date easily. I was impressed with the professionalism of all the employees of Deljo, especially Al and Steve, who did the actual installation. They spent around twenty minutes after completion of the project giving me an orientation presentation concerning the operation of the new heating system. In addition, when I suggested that I would prefer to have a certain component relocated to facilitate access to it, they very willingly accommodated my request. The quality of the work was first class.
Description of Work: Modernize our heating system by installing a Trane XV80 gas furnace (100,000BTU), Aprilaire 550 humidifier, Aprilaire 2400 air cleaner, and a Honeywell TH6000 programmable thermostat. In addition they corrected some duct work that was incorrectly routed; this process improved not just the heating, but also the air conditioning performance.

From the time I placed the call to Deljo to the time the service tech walked out my front door, it was under 2 hours. I expected to pay extra for the emergency service, so I wasn't too surprised with the bill. The $15 coupon in the February mailer helped (Thanks Angie). Jonathan was very professional and quick. I liked the fact that he showed me exactly what was wrong with my furnace. When the repair was done, he also suggested that I use a different type of filter to use, which would put less of a strain on the motor and my wallet. I appreciated that bit of information and the fact that he put shoe covers on before coming in. I would definitely use them again.
Description of Work: I woke up this morning to a cold house. I reset the furnace according to the manufacturer's directions, but no luck. I was hesitant to call anyone because of the premium for emergency service, but I wasn't about the spend the night in a cold house. I called Deljo and spoke to their answering service. Jonathan, a service tech, called within an half hour. He arrived about 30-45 minutes after that. He spent 10-15 minutes checking the furnace and came out with something that looked like a small electric stove coil. He explained (and showed me the damage) that the ignition coil was cracked. Jonathan replaced the cracked part and had my heat working in less than and hour. He also suggested a different kind of filter, which would put less of a strain on the furnace motor.

The quote was spot on- we had to add an upgraded thermostat, which I recently read about in a magazine as a cost saver. We used the $100 off coupon from Angie's List and the service was fantastic. The furnace made a few loud noises and we called and they came out right away to correct the problem. Thus far the furnace has performed to expectations, the humidity is better overall and the new thermostat allows us to really control all of our heat and humidity needs.
Description of Work: Quote for new humidifier and furnace for a duplex down condo unit.

Alberto came over promptly on the same day I phoned for an appointment (Margarita was wonderful on the phone), despite the snowy weather, and helped explain the inner-workings of our water heaters. The cold drafts we were concerned about was necessary for the water heater, but he did go the extra mile to look at our furnace as well and advised we use a different filter so we did not needlessly overwork our furnace. We plan on switching to an on-demand water heater in the coming months and will definitely work with Deljo again. They were reliable, efficient, and adequately priced for such wonderful service.
Description of Work: We just moved into our new house last month and noticed a cold draft coming into both water heater areas. We were concerned about insulating it and wanted a professional opinion.

I tried a couple times to fix the intermittent problem my furnace was having. Finally, I called Deljo on a Sunday evening. Jonathan arrived within a couple hours of my call. He was extremely professional and personable. My furnace had an intermittent problem and it happened to be operating when Jonathan arrived. He offered to return the next day if I had enough heat to get through the night and that would save me the after hours premium. I really wanted to get it fixed so I told him to make the repair immediately, but I appreciated the fact that he had the final bill in mind.
Description of Work: Jonathan debugged my furnace based on the failure mode that I described. He was very thorough and checked the thermostat and all the sensors on the furnace. He narrowed it down to the circuit board, which he said was a common problem with my Armstrong Air SX80 furnace. He had one in his van and replaced it on the spot.
