Jason with Assured stopped out and discovered our computer board on our 22 year old furnace was not working. He tried to get furnace running again and even went back to his shop to find a donor board. After discussing the age and shape of furnace it made sense to replace. Assured showed up Monday morning at 7:00am removed old furnace and installed new high efficiency furnace. Crew did a fantastic job, super clean and respectful of our home. Wonderful job Assure!

We first used Ron's Heating and A/C last summer when our central a/c went out. We were new to the…read morearea, so we asked our neighbor if she could recommend someone. She had heard of Ron's, but had never personally used them. They installed a new a/c unit, and we were pleased with their work and our new system. This past January, the 31'st, with record breaking temps, our furnace went out. We called Ron's, and they fit us into their busy schedule and sent Dustin and Dennis here. We were wearing our winter jackets in the house, and had the oven on for heat. At one point, they had to run to Rockford (an hour away) for a part. They spent about 4-5 hours here, but they stayed till we had heat. On February 19'th, we had Ron's come and install a new furnace. On March 1'st,we noticed that the furnace was blowing cold air. We called Ron's, and they sent Dustin (Ron's grandson) here to see what the problem was. When he got here, the furnace was no longer blowing cold air. He stayed about 45', could not find the problem, so he gave us his personal cell number and told us to give him a call if it started blowing cold air again. We noticed the same thing happening with the furnace over the weekend. It would blow cold air for 3-4 hours, dropping the temperature down to 55 degrees. We called Ron's on Monday morning, March4'th. This time, Dustin and his dad, Dennis, came out. Dennis thought it might be the our thermostat, so he installed a temporary thermostat. He told us to leave it set at 70 degrees and see if that was the problem. Also, these 2 visits would be at no charge to us. The same thing kept happening, even with the temporary thermostat. They had us email pics of the thermostat, recording the temperature drops. On Thursday, March 7'th, Dustin came out in the morning and hooked their thermostat on permanently . Also, Ron himself came out with the gas company. They switched out our meter with a new one, hoping this might be the problem. Still, later that afternoon, the furnace started blowing cold air and the temperature in the house started dropping. We called Ron's once again, and this time Dustin and Ron came to the house. This time, the furnace was still blowing cold air, so they got to see for themselves what we were experiencing. Ron made his way to the basement (using his cane, no less!) and checked on the furnace. He then called the company in Texas that made the furnace, and was on the phone with them for about one hour. After all this time, it turns out it was a bad/faulty igniter from the factory. Dustin went to his truck and got another igniter, switched them out, and, voila, problem solved! We haven't had any problems since. The company in Texas, and also Ron's company, said they had never had this happen before. When my husband called Ron's office the next morning to see what we owed them (for the new thermostat and their several visits,) he was told by Ron that would be no charge because of the inconvenience to us. In closing, I would say our experience doing business with Ron's was very positive. They are dependable, reliable and trustworthy, and take pride in what they do. We would recommend them to anyone in need of heating and/or a/c. Paul and Deborah Bougher Sycamore, IL

Everything is the customers fault with this company. The owner talks to you like you're beneath…read morethem when you question their work or judgment call. You are right I am not a expert in heating and cooling that is not my profession. I hired another company turns out there was a leak in the fiberglass tape that caused the issue. Ron's heating blamed the builders saying not enough insulation or etc. Well you're wrong. You guys come to my house for 10 minutes . Yes it's on camera you can say different but it shows when you stepped in the doors and drove off. Total 12 minutes. You guys want to charge me a diagnostic fee FOR WHAT? You guys didn't diagnostic the issue another company did within 30 minutes. Get a second opinion before hiring this company because they are a one sided company and that side only Benefits them. I have my newborn room with improper heat coming into the room. It's 61 degrees when the house is set to 70 degrees and they blame the builders when it was due to their issue that they didn't even diagnose another company did. JOKE of a company. I tried paying the diagnostic fee that I honestly shouldn't because they rushed and didn't even spend the time to figure out the cause. They wanted to charge me a 3% fee for a debit card. Then they tried to charging me for a visit the the prior owner did and never collected on me. The owner wife was trying to pull a fast one on me then said ohh sorry I didn't realize it was a different name. Luckily I asked my total before providing my debit card number

Harmonic Heating and Air Conditioning is the BEST!!! Our AC…read moredied and after another company told us that our unit could not be repaired and had to be replaced ($6,000), we contacted Harmonic for a second opinion. Daniel the service technician opened the unit up and tested everything. He took the time to explain what he was doing and why. He discovered a bare wire that had been chewed (possibly by a mouse) and was touching the metal housing which tripped the circuit breaker. Daniel replaced the wire and the unit is working perfectly. The honesty and integrity of this company is refreshing. We will not hesitate to use them again and recommend them to all our friends.

Stay away from this business! My entire cooling and heating system was left in an inoperable state…read more I called for a diagnostic of the air conditioner today because cool air isn't coming from the vents. I was told the diagnostic would cost $149. I asked to be informed of any repairs that had to be done. Technician checked the system and recommended replacing unit. We discussed replacement unit and cost. I was ready to pay deposit. In the next 10 minutes I was told that the model I selected is old and not available. New model costs $1000 more. I asked for a proposal to decide later. Technician told me that the visit costs $396. He said that he fixed air conditioner that was not working. He never told me that he is fixing anything. Through our the visit it looked like he was figuring out the problem. I talked to the owner and we agreed that any repairs that were done will be undone so that I do not have to pay for repairs. Then the technician removed all the wires from the board making both heat and fan unusable. He did not just undo the "repairs", but made entire system unusable including fan and heat which were working before his visit. See the photos to show what was done!

Fast HONEST service!…read more Our furnace started making noises as we came out of the -30F Polar Vortex. Since we had a good experience with a humidifier repair a while back, we decided to give Hampshire Heating and Cooling another call. They came out on Monday afternoon, and everything seemed to check out OK. Bob, the tech, said that sometimes these things could be intermittent, but that they would come back if the problem happened again. Today the furnace was making the noise again. I made a quick video and sent it to them. When my wife came home at about 3PM, the furnace was making a loud buzzing sound, but was not putting out any heat. I called Hampshire Heating again, and they had Bob call me back to say he'd be out around 5:30. Bob found the problem quickly; we needed a new blower motor. Fortunately he came prepared with the proper part. He finished the repair, and was able to get us up and running quickly. Since he'd been out the day before, there was no additional trip charge. The cost of the blower motor was actually a bit less than we expected. We are very pleased that they could come out quickly, and get the unit fixed so we did not have to go a night without heat. We will definitely use them for our future HVAC needs.
