It went very well. While the install took longer than expected, the cost was the same. The only problem was one of the installers writing on the second unit to show us distance from the property line. We could have been told and shown this without writing on the unit.
Description of Work: One of our two central AC units was broken. Deljo replaced the unit and provided advice on which unit to buy and what was necessary to qualify for federal tax breaks.

They have done a great job. They may be a little more expensive, but you do get what you pay for. The follow-up and continued service I receive has been wonderful.
Description of Work: Most recently they replaced my hot water heater. They have previously replaced my furnace and air conditioner and continue to perform annual service on those units.

They were very professional and gave us straightforward answers on our questions and concerns on the unit. I had originally scheduled an 8 am appointment. The person didn't show up on time, but someone from the office called and advised they had made a scheduling error in their system so apologized for the delay. The person eventually arrived by 9 am. Overall I was pleased with Nathan's visit and professionalism.
Description of Work: We moved into a new condo and had them come out to check out our a/c. They came out and checked thermostat register, output, freon, and cleaned the a/c unit.

The technician arrived promptly (called me when he was on his way) and put on booties before entering the house. After looking at the leak, he determined that a small plastic pipe had split, and he went about replacing it. Other contractors had told me I needed a new coil at a cost of $1500! He cleaned and recharged the Freon to fix the freezing/bad cooling problem. He explained that I could get most of the recharging for free if I joined the annual heater/AC maintenance plan. Normally I don't sign up for these kinds of package deals, but in this case it was worth it since it includes a discount on service and also higher priority on emergency calls. The latter is important to me since I often travel on business and want my family to be taken care of quickly if the heating or AC breaks down. It also helped that the technician was very friendly and respectful. He was able to explain things at a level that made sense to me (I'm pretty knowledgeable about handyman-type things) I can't imagine a better service call.
Description of Work: Air conditioner was freezing up and not cooling well. In addition, water was leaking out of the side of the inside unit.

I called on a Tuesday and got an appointment for Friday of the same week. I was a little peeved when I was told that their website-advertised $50 off for first-time customers did not apply because it only applied to "service calls". They did say they'd honor the $10 coupon from Angie's List (which also applies to "service calls"). They were supposed to come between 1 and 3:00. At 3:10, when no one had arrived, I called and they said that I was not even in their system. They offered to come out on Monday, but I had taken the day off work on Friday and could not do so on Monday. They did not really apologize for the inconvenience, or offer anything to make me want to use their company in the future. Which I will not do.
Description of Work: Supposed to clean and perform routine maintenance to my air conditioner.

Response from Deljo Heating & Cooling
I would like to offer an apology to the member. Deljo has, admittedly, done so many things wrong as stated in her complaint. The part of loosing her appointment is completely unacceptable. Deljo's software is set up in such a way that the call should have been booked while the member was on the phone and scheduled at the same time. The part about the coupon makes me the most embarrassed. The coupon is for anything, and the staff at Deljo has been told that. In an effort to make amends, if this member is willing to give us another try, we would do the maintenance check for free and on day or time that they want. Unfortunately, we do not have any of the members information, because it was never added to our system. If the member that filed this complaint wants to call again, please ask for Bill or Mark. Again, we offer our sincere apologies and do hope to get a second chance.

We purchased an old home that needed everything. The furnace was on it's last legs, and the 50 year old air conditioning compressor had plants crowing out of it. First on our to do list was a new heating and air conditioning system. We interviewed many fine companies from Angie's, but Deljo's representative Frank Weitzel was the reason we selected Deljo to do the work. Frank was thorough in his inspection of our home, measuring square footage, counting windows, walking the exterior etc., before giving his recommendations on the furnace and air conditioning systems that would best work for us. He even noticed that the previous owner had replaced all the supply vents with return vents, in her attempt to spiff up the house for sale, making for a less than efficient distribution of heat, so recommended the replacement of them as well. We received his recommendations and estimate by email as well as hard copy very quickly followed by a call from Frank asking if we had any questions about the cost and information. We decided on a Trane Furnace and air conditioning compressor. When the day of installation arrived Frank arrived with the crew who then proceeded to completely remove and dispose of the old furnace and air conditioner, repacing them with the new ones. They were neat, efficient and fast as they set about their work finishing the job in a day and a half.. Casey, the head of the crew went over complete instructions as to how to run the system before packing up and leaving. At the end of the day Frank arrived to make sure all went well and to assure me if there were any problems or questions I could always call him. Acompany can only be as good as the people that represent it. As far as I'm concerned Deljo is at the top of it's field.

One of my rooftop condensers went out. The first HVAC guy said I need to replace it at a cost of $4000. I got two other bids to be safe - the first bidder put in a bid for $2500 to replace it, and the second, Deljo, said, "A condenser this new shouldn't break; there might be a cheaper fix." So they did an inspection, found the cause, and fixed it for $550. They are now my HVAC vendor of choice, and I have been in commercial real estate for 10 years now.

RFH system has a half dozen knobs and switches. Our dog-sitter had mistakenly switched one of them off. Embarrassment! Technician taught me the basics of how the system works for future use, and didn't charge for the RFH portion of the trip. Technician did a clean and check on one of our furnaces. Quick yet comprehensive.

I had a horrible noise in my furnace and called Deljo. They came out the same day of my phone call, and showed up at the beginning of the time window they provided. The service worker identified the problem as the motor for the fan, and tried the "cheap fix" of lubricating the motor. Unfortunately, this didn't work, and a new motor was required. This was installed quickly, and the amount of air blowing in my condo increased dramatically. I guess I had needed a new fan for quite some time as I've lived in this condo for two years and never had that much air blowing in! Deljo did a great job responding quickly and professionally. I will definitely use them in the future and plan on having them come out in the next couple of months to service my air conditioner.

Researched Angies List for a HVAC contractor. Saw the reports on many but choose to only call the one. I figured based on their reviews that this is the company that I would like to work with on a major investment like this. Called in the morning on a Thursday and asked to get a quote of a complete new system. I was put in contact with a salesman Brian. Let him know that I am looking at putting in a new High E system for my first floor and basement level. He asked how many others I would be getting quotes from. I said I had spoken with a guy that I had used in my past but for this install was looking at contracting a larger more established contractor, and that he was the only one I was calling. We spoke briefly about the system that I would like and the area where it was to be installed. I mentioned that I was anxious to get it done quickly since I have scheduled a contractor to refinish the basement starting later the next week. Asked for a Thursday evening appt but was told Friday morning was the quickest. He arrived promptly at 8:30 Friday morning. I took him to the location of the furnace and we began talking about the system and what my issues were. I wanted some ducts worked on in order to provide better airflow to the back of the house. He mentioned how slow it was out there and that he is working up great deals now. Started talking about Heat Pumps and a bunch of other options. I said great, asked him to let me know what the cost would be for the system as I originally requested along with some other options to consider. Told him I was ready to go on this and was looking for top of line equipment. He took a measurement or 2 and I asked him if he wanted to sit at the table to work up the quote. He said that he does not do it like that and he will go back to his office and work up the quote. I asked if he could email it to me as soon as it is ready. He said no problem and that I should have it by noon that day. I never saw the quote so at 6pm I called Brian and asked if he had a chance to send the quote yet. He said not yet and that he was almost done and should have it soon. So I then said, ?about an hour or so", he then said "yea, or maybe tomorrow." I was a little shocked at that answer but figured if I got it on Saturday, they would still be able to start on Tuesday so I could get my other work started by Thursday. Nothing on Saturday came, nothing on Sunday, and now it is 6pm on Monday and absolutely no contact from this guy at all. It is too bad as I was a sure sale. I am glad that these guys are so busy that they are able to choose which deals to bid on and those to pass on. I now need to start all over again researching to find another acceptable contractor and now need to push off my start date for my other work.

This was one of the best service companies I have dealt with.
Description of Work: I had no heat. Greg came out and quickly diagnosed the problem, replaced the part and gave me some great information about how our system was installed. Since I was a new customer, he told me there was a coupon on the website that I could use to save on the cost of the repair. This is definitely my new HVAC company.
