Deljo came out 1 year ago when our heat could not keep up with the cold. They said that it was because of an intake vent that needed to be cleaned and there was nothing that they could do. We cleaned the intake vent, but still spent many days where the internal temperature in our home did not get above the 50's last winter. We began to run into the same problem this year and, given we have a newborn and it is the start of the winter, we called another service. The other service informed us that it was not the intake vents and that the problem was in the furnace and that it was causing the furnace to constantly shut itself off. They said the procedure would be difficult, but would fix the problem. We now have heat that can keep pace with the winter no thanks to Deljo. Deljo also tried to charge our condo association $8000 for a water hear that we had installed for around $5000.00. Ultimately, their work has proven to be iffy, but their bills are consistently expensive.
Description of Work: We needed our furnace fixed so it would keep up with the winter cold.

Excellent. Receptionist, with my initial phone call, was polite, professional and knowledgeable about humidifiers. She made an appointment for the technician to come out two days later. The technician (Geoff) was very good; he explained what he was doing as he checked our old humidifier and clearly explained what the problem was. He told me the options (get a new motor or replace the humidifier) but did not pressure one decision over another. When my husband and I decided to go with a new humidifier and have the company install it. Geoff was the technician who installed it. He did an excellent job; checked that all components were working with attention to detail. He was thorough, for example, he cleared out the u-shaped drain to the waste stack. He was polite, considerate (it was snowing outside, so he put on foot covers over his shoes whenever he came in the house), he left the work area neat, he knew what what he was doing. Very professional.
Description of Work: Inspected whole house humidifier which had been leaking water; found out that the motor was not working. Since this humidifier was at least 16 years old, we decided to get a new one. Deljo did this job; we got the humidifier (Aprilaire 350, just like the one it replaced) through them and they installed it.

Deljo was very accommodating. All my questions and concerns were dealt with in a timely manner. The workers were professional, efficient and kind. Though the price was a little higher then other quotes, I felt I walked away with a good product that was installed professionally. I would recommend them to others looking for a hassle free, well implemented job.
Description of Work: Installed 3 new Trane furnaces in basement. One of the furnaces replaced an old furnace, the other 2 replaced wall heating units on the 2nd and 3rd floors of property. Hole was cut through middle of house to supply returns to furnaces in basement. Ducts were added to 2nd and 3rd floors.

John came out the same day I called and did a complete analysis of my home to estimate the size furnace needed. He had a "pre-packaged" presentation to familiarize me with Trane and Deljo, and it was hard to get him to ignore the cooling part of the presentation, which I didn't need. He estimated the price would come in at $4,200, but said he would e-mail a proposal once he had analyzed the furnace size. You can imagine my surprise when I received a quote for $8,600! This was especially hard to understand since I had gotten a quote of $4,600 from another company for the same furnace. When I called and asked if there had been a typo, he said no. The response to the information that I had received a substantially lower quote for the same furnace was to say he would go back and see if he could "come close". I told him not to bother. If he could come down $4,000 in price, I didn't want to buy the furnace from him.
Description of Work: John Ciszek provided an estimate for a high-efficiency two-stage variable speed Trane furnace. ($8600)

Scheduling is great, if you give Deljo some notice (1 or 2 weeks) they will do their best to send the technician of your choice. I always ask for Bruce, he is fantastic. Bruce always arrives on time or if he is held up at a previous job he will have the office call to let us know. Bruce is personable, professional and if you ask for advice he doesn't try to up sell you. Our HVAC system was poorly installed and we are working together to make the most what we have. I'm sure Deljo/Bruce will increase the service life of our system and get it running efficiently. This is not the first time I've used Deljo. For first time users be sure to ask for Bruce otherwise you may end up with someone with less experience who works by the book and doesn't think outside the box.
Description of Work: Serviced AC/Heating. Deljo has a service contract called Goldstar Service. Our contract costs $525 per year to service the furnaces in fall and Central AC Units in spring. We have two furnaces with Humidifiers and two AC units. The AC check up includes checking the freon levels, adding freon is an additional charge. The service contract covers the cost of replacing the humidifier pads but does not include replacement air filters.

This went very well. They were very thorough.
Description of Work: I called Deljo to do a maintenance check on my heating and to install a digital thermostat. They arrived when they said they would, gave me the Angie's List discount and performed a 21 point check. I got a one-year service contract to include A/C check and maintenance for next summer and received a further discount on that.

I am really pleased with the service I received from Deljo. Being that I have 2 kids, the hard winter without heat would be too extreme for them. I really appreciated the fact that they came to help me at the last minute.
Description of Work: It was in the middle of winter and late in the afternoon on Friday, when my boiler gave out. When I would turn up the thermostat, there was no heat. When I called Deljo, they came to my place within a couple of hours and fixed my boiler. I'm not sure what they did to it, maybe an adjustment of some kind but it took them less than an hour to correct the malfunction.

Excellent. The customer service person on the phone was very friendly and professional. She had a number of times available (some next day) that were convenient for me. I was also given a two-hour window during which the technician would arrive so I didn't have to take the whole day off from work. The technician (Rudy) arrived promptly and did a great job. He was very thorough.
Description of Work: Cleaned and checked furnace, checked and added Freon to a/c.

I do think that they are a little pricey. However, they do pretty good work. They are very good about scheduling and getting out here on time. Everything went fine with this replacement. I thought they did just great and I have no complaints with the work that as done at all. I would gladly recommend them to anyone.

I was impressed with their ability to send someone quickly (right at the start of the cold season, when I imagine many people are noticing their furnaces aren't working properly). Greg was amiable, courteous, and helpful.
Description of Work: Our furnace was turning on for about a minute and then shutting off. I called in the morning and they were able to send someone by 11:00! It turned out we needed a new circuit board. The technician (Greg) located one, went to pick it up, and returned to replace it. He was finished with everything by around 1:00 that day, and we have heat again!

Fantastic!!! They cautioned me that although my boiler is a good brand, it's old and the pipes are pretty corroded. I appreciated the fact that they never pressured me to purchase a new boiler but gave me some solid advice on how to handle it as it ages. I now have a good idea of what to watch, which parts can be economically replaced, and when it will be most cost-efficient to replace it completely.

I like using Deljo because they are reliable, affordable and fast. Everything works great and they were able to install it in one day after they got it in from being ordered. The only thing I wish they would have told me that they didn't was the size of the unit. It is bigger than the old one and it is taking up more room on my roof top deck than I would like. I would have at least liked to have been made aware of that.

I can t say enough good things about this company. We had other service repair companies come in and every one was saying we needed a new furnace. These guys came in found what the problem was and fixed it. They saved us over three thousand dollars. The best part about this was that the part they replaced was only twenty five dollars. They have showed me several things that I can do on my own to save a service call. I like the fact that they are upfront and honest with you. They are not going to try to sell you something you don't need.
