The HVAC technician, Greg, was very thorough, polite, and very clear in answering all my questions -- in one case calling back to his colleague to confirm what he was telling me. My only issue was that my 8AM appointment was somehow lost in the shuffle. When I called, the woman I spoke with was very polite and responsive, and they did get someone out later in the day.
Description of Work: Clean, service and add Freon to A/C system; addressed issues raised by my home inspector and People's Gas. (I just purchased home.)

Greg arrived at 2 pm, easily within the 1-3 pm timeframe I was given. He was very nice, polite, and professional. Greg went right to work, and completed his work efficiently, in about 30-40 minutes. Although I'm not an expert, he seemed to do a thorough job. I had a positive experience with Deljo, and I plan to use them again in the future.

Easy to schedule appointment. I especially liked the fact that I could request 1st appointment of the day. Rudy showed up on time. Was politely waiting for 8am before he rang the door bell.
Description of Work: I found Deljo through Home Depot. They replaced my heater in March 2005. Very happy with the installation and follow-up. I used them for the 1st time for annual maintenance on Heater. (Cost is noted as $0 since maintenance for Year 1 came with the purchase of heating system.)

I was pleased with Deljo and their service man, Bruce. Bruce was very friendly, clean and explained what he was doing. The work took a couple hours longer than they expected, but Deljo did a good job at a reasonable price. I liked the company and I liked Bruce and I will continue to use Deljo for my HVAC needs. I rated Deljo a ''B'' on price because the original quote that they gave me was for only one item on my punch list - not the whole job. They called the next day to report their error which I appreciated in advance. In any event, my expense was in line with my expectations, but a lot more the first incorrect quote.
Description of Work: I recently purchased a house and I had an excellent home inspector who suggested a number of heating and air related improvements that were both safety related and efficiency-related. Deljo came out to do an estimate of the work and spent about five hours going through the punch list of items.

Deljo's service agent was accommodating in answering my questions. It's a new house for me and he showed me how to manage the pilot light on my gas fireplaces. He was also accommodating when I decided I wanted to have the thermostat replaced even though it wasn't scheduled. I recommend signing up for their service plan which includes two seasonal checks, priority service, and other discounts.

We have used DELJO several times. We had two different men come out and each one was very nice and was very efficient in diagnosing the problem. Both men were honest and the repair costs were very reasonable. The repairmen names were Greg and Mann (last name). I would highly recommend this company. When scheduling a service call request either of these men.
Description of Work: The service man came out, on time, to look at our hot water heater that stopped working. He was able to figure out the problem right away and correct it.

It took the technician about an hour to clean up and do some regular maintenance. Nice guy, on time, and answered all my questions.
Description of Work: This is the first time I had my old furnace cleaned and checked up on in the 5 years I've lived in my place. The technician showed up and cleaned the pilot light area (he said it was showing a white flame, so it was pretty dirty) and vacuumed away most of the dust. I have an electric air cleaner which really didn't do much in the way of filtering, so he recommended that I use a separate air filter, which he provided free of charge. He said the furnace, while old, was working just fine.

Bob, at Deljo, originally did not get back to us, but when another project came about, he quickly came out to give us an estimate. We chose to go with another HVAC company, as Deljo's quote was twice as expensive as another company for the same work.

First-class experience all around. Very responsive to our initial call asking for a quote. Subsequently, Deljo moved very quickly to remove the old furnace/water heater and install the new equipment. The work was done very professionally, including the Deljo reps offering tips/suggestions for some minor ancillary items. Worksite was left cleaner than when they arrived. All Deljo people we dealt with were very cordial and helpful. We can't comment on the price relative to other firms, since we were so impressed with Deljo, we signed up with them and didn't get any additional quotes.

They were wonderful. When they removed the old, rusted furnace, bits started breaking off on the way out the door. They did a great job cleaning it up. After the install, they explained how to use the new thermostat. They called the next week to answer any other questions and ensure everything was working properly. I highly recommend them!

These folks are great. Well organized and Tom really knew his stuff.
Description of Work: It's a miracle. I had a ''no heat'' emergency on a Sunday night. The company called me back within 15 minutes. They were backed up with service calls and unable to get to me until the next day, but the technician, Tom, was able to diagnose my problem over the phone and tell me how to fix it. 20 minutes after the first phone call, I had heat.

I checked to confirm the first appointment, but the scheduler had been off the week before and couldn't find it so we re-scheduled. I was thrilled when the workman that came out for a 7:30 a.m. weekday appt was prompt maybe even 5 minutes early. He spent a good hour looking things over - fixed a damper that wasn't working correctly. Put in a new filter for the humidifier and brought a new filter for the furnace but it was the wrong style, however I had purchased some new ones from Home Depot and I just put one of those in.
Description of Work: The annual furnace/humidifier check that I had never done since living here.

OUR CONTACT, BOB TURK, HELD OUR HAND THROUGHOUT THE WHOLE EXPERIENCE, FROM EXPLAINING THE DIFFERENT HEATING AND COOLING OPTIONS IN OUR OLD HOME TO INSTRUCTIONS ON MAINTAINING OUR NEW SYSTEM. HE WAS ALWAYS AVAILABLE AND RESPONSIVE TO ANY QUESTION OR CONCERN. THE WORK CREW, LED BY ROBERT WAS UNFAILINGLY POLITE AND EFFICIENT, AND DID AN IMPRESSIVE JOB AT FINDING WAYS TO INSTALL THE EXTENSIVE DUCTWORK WITH A MINIMUM OF CHANGES TO THE INTERIOR STRUCTURE OF THE HOUSE. THE JOB WENT OFF WITHOUT A HITCH, AND WAS AN INCREDIBLY PLEASANT EXPERIENCE FROM BEGINNING TO END. I WOULD HIGHLY RECOMMEND DELJO FOR ANY HEATING OR A/C WORK. ALTHOUGH THE PRICE WAS ON THE HIGH SIDE, IT WAS REASONABLE CONSIDERING THE AMOUNT AND THE QUALITY OF WORK PERFORMED.
Description of Work: DELJO REMOVED THE OLD HEATING SYSTEM (WITH BOILER/RADIATORS) AND INSTALLED TWO NEW FORCED AIR HEATING AND COOLING SYSTEMS TO COVER THE FOUR FLOORS OF THE HOUSE. THE BOILER, ALL RADIATORS, AND ACCESSIBLE PIPING WERE REMOVED, AND ALL NEW DUCTWORK WAS INSTALLED THROUGHOUT THE HOUSE. THE TWO NEW FURNACES WITH ACCESSORIES WERE INSTALLED IN THE BASEMENT AND THE ATTIC, AND THE A/C CONDENSERS OUTSIDE, WITH ALL NECESSARY ELECTRICAL, GAS, AND WATER CONNECTIONS.

I WAS VERY PLEASED WITH THE WORK DONE BY DELJO. BOB TURK, THE ESTIMATOR, WAS ON TIME AND SPENT AN HOUR WITH ME LOOKING OVER MY HOUSE TO FIGURE OUT HOW TO ADD AN ADDITIONAL RETURN DUCT. ALTHOUGH THEIR ORIGINAL BID WAS ON THE HIGH SIDE, THEY REWORKED IT TO BE MORE COMPETITIVE. THE INSTALLATION STAFF WAS VERY PROFESSIONAL AND CONSIDERATE. IN FACT, I NOTICED THEIR RECIPROCATING SAW AND MENTIONED THAT I NEEDED ONE FOR A VERY SMALL PART OF ANOTHER PROJECT I WAS WORKING ON -- THE INSTALLER OFFERED TO CUT OUT THE STUCK BOLT FOR ME. IT ONLY TOOK 5 MINUTES, BUT HE EARNED PLENTY OF BONUS POINTS! THEY DID QUALITY WORK AND CLEANED UP THE BASEMENT WHEN THEY WERE DONE. I HAVE SIGNED ON FOR THEIR ANNUAL MAINTENANCE PLAN.

DUE TO THE FACT THAT OUR HVAC UNIT WAS ASSEMBLED IN THE ROOM WHERE IT EXISTS, IT WAS A REAL CHALLENGE TO ACCESS THE BLOWER MOTOR IN ORDER TO REPLACE IT. THE DELJO REPRESENTATIVE LITERALLY SLAVED AWAY FOR AN HOUR ATTEMPTING TO FIND A WAY TO REMOVE & REPAIR THE FAULTY COMPONENTS. WHILE IT DIDN'T WORK (WE ULTIMATELY HAD A TO TAKE DOWN PART OF A WALL), THE COMPANY & ITS REP DESERVE TO BE COMMENDED FOR THE EFFORT.
