Prior to calling Demilio, I changed the fuse and the filter to be sure that wasn't the issue. When I called, the woman on the phone to inform her we had no heat, she was polite and stated that she hoped to have someone at our home before lunch. Not long after calling Demilio, the technician arrived. The technician came in, ran diagnostics, and discovered that the ignitor was bad. He promptly researched and picked up the part and returned to install it. Currently, the heat is now working and we are beginning to warm back up. Our experience was positive and we will definitely consider Demilio when servicing heating and air conditioning in the future!

Description of Work: Called them with a problem with my one geothermal furnace. service man was very inexperienced and just flipped the fuse box to reset the unit. this fixed it for like 24 hours and then it stopped working again. I called another company. Paid a small amount but this guy didn't know much if anything about geothermal heating. Found E&D company in Latrobe and they were great!

Everything went great. Between the quote and the day of service, everything was complete within a week (the project was done in less than a day). The worker was very professional, cleaned up the work area very well, and the finished project has made a huge difference in bringing heat upstairs. We would definitely have them do some work for us in the future if the need arises.
Description of Work: They added air intake/vents in our basement, connected to existing ductwork, in order to draw more of our hot air (from the woodburner) to the upstairs.

Carrier Heat Pump install 7 years ago. Thermostat had 10year warranty. Thermostat went bad. Call Demilio Heating/Cooling. He charged $360 to clean outside of heat pump and left to go get a replacement thermostat. The technician told my wife the thermostat was not covered under warranty and installed a new $700 thermostat. Total bill $1100.00. Never left a itemized bill. Took old thermostat(still under warranty). I came home to find this out. Called and left a message for Demilio to call in morning. The company used to be reliable. I would not trust them anymore.
Description of Work: Replaced a faulty heating/cooling thermostat. Before they came out for service they said thermostat was under warranty. When they arrived, they said the thermostat was not still on warranty. Without giving me any options, they proceeded to replace the thermostat with a $400+ model. Had I known, I could have bought a replacement on ebay for $89. When I told that to Demillio, he said he actually had a pile of used stats. Of course they never offered them. They initially charged me over $1100, but after I spoke to them, they reduced to $860. Bottom line. They charge $425 labor to replace a thermostat and basic cleaning. Since they didn't bring a thermostat with them, the total job took 4 hours(and it appears, from the $425 labor, I had to pay for the stupidity of the technician that did not bring parts. When I spoke to Demillio about the high original charge, he started saying that he had over $10000 of non-payments. Why tell me that? Looks like he tries to recover the non-payments, by overcharging good customers(I have used them for 7 years before this). Bottom line. I would NEVER use them again, and will make sure ALL know.

Response from Demilio Heating & Cooling
We are sorry you find us an unreliable company. Your thermostat was a Carrier INFINITY CONTROL S/N: 4407W000291. In the thermostat serial number you can find the 07 which shows the manufacturer year, and we installed the unit in 2008. The thermostat had only a 5 year warranty which put your thermostat OUT OF WARRANTY proving your statement was incorrect. The old Infinity Control is no longer made and was replaced by a touch screen Infinity Control. We did not have inventory of the new thermostat at the time of call. Our technician had to drive to our wholesaler to pick up new thermostat. We discounted the price of the new thermostat. We provided maintenance on the Heat Pump, Furnace, filters, and installed the new thermostat at a total of $863.20, not the $1,100.00 you mentioned previously in your complaint.

My Oil furnace was making noise which I felt was a problem with the pump on the fuel line (It was not leaking, just making noise). I called DeMilio and scheduled a cleaning and tune-up with the understanding that the tech would also look at the noisy pump. The DeMilio tech came on the appointed day and time and diagnosed the problem saying it was probably the pump coupling and retrieved one from his truck. After replacing the coupling, the noise was still the same, so the tech said it must be the pump. He checked his truck and had a pump on hand so he proceeded to r&r the pump. This is where we ran into a problem. The tech asked me to cut off flow in the fuel feed line, which I did, but he said the second line (an overflow return line) would be okay (I suggested that we separate it at a junction on the wall nearby and stop it up), but we left it alone. Well, when he removed that line, heating fuel began gushing out of the return line all over the inside of the furnace, including throughout the air intake area. I suggested he might redirect the tubing (since it was flexible copper tube) over a bucket he had with him, which he did, but the damage was already done. He worked for about 5 to 10 minutes wiping up the fuel spill with paper towels, meanwhile, the fuel was still freely flowing out into his bucket (which was also filled with dirty rags, old furnace parts and used paper towels). I then retrieved some materials to plug the end of the tube with some success, fearing his bucket would overflow. The tech could not remove the plugs from the new pump, so i took him to my garage to let him use my vice, enabling him to assemble the new pump fittings. Upon returning to the furnace, the tech attempted to reattach the return line over top of the bucket but soon realized that the fuel would flow through the pump and all over the inside of the furnace again. In his haste to get the pump back out over the bucket, he kinked the return line (he later squeezed the line with pliers to take some of the kink out). Eventually I took it upon myself to disconnect and plug the return line at the junction on the wall and stopped the flow of fuel. The tech was then able to install the pump and the lines without further mess and loss of fuel. The tech was a really nice young man who, it seems, was not well versed in oil furnaces as he kept apologizing profusely saying he had never experienced anything like this before. The Tech then replaced the nozzle as part of the tune-up. To his credit, he was apologetic and tried his best to clean up the inside of the furnace. However, I spent the next hour+ cleaning the floor and the inside of the furnace with degreaser and odor neutralizer to no avail. The air intake compartment still smelled like diesel fuel and spread that smell all over the house. The smell was so bad that I got physically sick to my stomach from it and seriously considered getting a hotel room for the night. We toughed it out, but it was over week before the smell was cleared out. UPDATE: Dave DeMilio called me this morning and was very cordial. He indicated he had misunderstood the problems with the service call, apologized, and wished to make things right, which he did. He also indicated that he spoke with the service technician who had performed my work and addressed and corrected the issue with him. He seemed earnest and his actions indicated he was such. As a Christian, I am a believer in second chances, so I have updated my review to indicate that I would, indeed, be willing to call them again for service.

Response from Demilio Heating & Cooling
Customer called three weeks after the job was serviced when he received his bill. He never called after the service man fixed his furnace to complain about the quality of the service, only after he received his bill. He called because his oil furnace was down and no-heat and we responded the same day to fix the issue. All oil furnaces are piped in differently and if the original oil tank was installed properly with shut off valves, there would have been no issue with the mess. Furthermore, when our technician arrived at the job, there was already oil dripping on the shelf of the furnace due to a faulty seal in his existing oil pump. He was already aware of the oil smell when the technician entered the house because he told the service man the reason he called was the smell and noise coming from the furnace. On occasions, when you open the oil lines some siphoning may occur because of the height of the furnace and the oil tank. After talking to Peter, our technician told me that their were existing oil stains on the floor. Our technician is experienced in servicing oil furnaces with well over a hundred of successful service calls on oil furnaces with no complaints other than this one. The only reason the customer is unsatisfied is because he didn't want to pay his bill. He insisted after the service call that he could have fixed the furnace with parts he could have bought from Amazon for a fraction of the cost of the invoice. He wanted the furnace fixed promptly, which we provided.

I wouldn't recommend these guys to anyone. We had them come and replace a furnace in a house that we had just purchased. Initially, I was happy at the responsiveness we received, but as soon as we identified a problem, we couldn't get them back out to the house. With all the government rebates, they were not interested in fixing problems; they were only interested in new jobs and new revenue. Here it is, a year and a half later (still having problems by the way) and I've asked for new quotes from three totally different contractors and each one has identified all the problems with the installation by Demilios. The unit is undersized, the installation work is undesirable, and there are many problems with the duct work, which Demilio's never caught.

Response from Demilio Heating & Cooling
This was a new house that Demilio installed new duct work 15 years previous. At the time of said work, the basement was unfinished. The builder, Art Noble, finished the basement without contacting Demilio. The contractor installed duct work in basement by another sub contractor other than Demilio. Previous homeowner lived in that house for 12 years with no complaints. Bridget purchased the house and the existing furnace needed replaced. We installed new furnace and informed her the replacement would not control the basement. We proposed a separate unit in the garage to control the comfort in the basement, and we also proposed installing a heater in the garage. Bridget refused both proposals.
