"The owner, Steve, came out and explained everything and more that I should be aware of regarding the replacement of the 26 year old furnace and Air conditioning units. He was a pleasure to work with and the price quote was more than acceptable. I did accept and within the week the crew arrived to do the installation. Al and Damien were very professional and the work was extremely well done. They finished that same day and when they left it was if the new units had always been there. I was extremely impressed and will certainly go back to them for future maintenance. You can't go wrong with this company!"

"It went very well. We didn't know why our furnace didn't work, so Adam arrived and ran diagnostics while keeping me informed of exactly what he was doing and why. When he determined that the furnace was fine, he showed me the thermostats that he had available and then installed the one that I chose. His company also provides a furnace upkeep program that does bi-annual cleaning and diagnostics of the furnace and air conditioning units. Since he clearly knew what he was doing, we decided to sign up for their program. The approximate price below includes the cost of 1) an emergency, overtime service call 2) the replacement of the thermostat 3) the annual service program for 2 furnaces."

"We called United Heating and Air Conditioning for an annual furnace inspection for our new home. They scheduled quickly and easily. We then had a conflict and they re-scheduled just as easily. When they inspected the furnace it turned out it was extremely old and no longer safely operable. We required an emergency replacement. This was in November and we didn't want to be without a furnace. United Heating and Air Conditioning was able to come the next day (!) and install a new furnace. They took care of the installation, confirmed it worked, and hauled away our old furnace. They were quick and professional and stuck exactly to the quote. We were extremely satisfied and will definitely be reaching out to them when it's time to check (and possibly replace!) our air conditioning unit. Highly recommend!"

"My furnace was making a lot of noise and I had a company come out to dagnose and quote on it.  They quoted me over 800 to replace the fan, motor assembly, and a capacitor.  I felt that was a little high so I had put the prices on Angies List to have some quotes for comparison.  TR millers quote cam back around500 so I scheduled the work. Upon arrival they checked the furnace and determined the only thing I needed was a fan and charged me 36. for the fan and 95 for the call.
What a breath of fresh air to have someone honest come work on your house.

"I needed a new air conditioner for this coming spring and summer I had a couple companies lined up to come to my home here in Bolingbrook, from Best rates heating and cooling from Oswego came out with his daughter, and he noticed that the furnace was giving issues. He asked me if there was anything going on, the amazing part about it is I went down with both of them even his young daughter who is nine years old asked his father and said hey Papa, the furnace is not supposed to be making that booming sound right thatâ s when I knew that I was gonna be going with this company for his daughter to know at such a young age how a furnace should operate he responded with. Itâ s not operating well but weâ re going to figure it out. Keep in mind I had called him for the air conditioner on he checked the age of the unit and the brand-name and he brought me up to speed. My unit was 14 years old after he said what was causing the booming sound was that I had a flexible gas line and he said that he would repair it for me. He also went above and beyond and check the inside of the furnace and the condition with his camera and I saw that it was rusting up in the inside. His professionalism was great he said we can continue to the just AC If you would like to, but you may only have a couple years left. He gave me both options for both. I went forward with him. Right away You canâ t shop that type of customer service. The morning of the install it was raining I thought to myself maybe they will reschedule Shirley enough. They showed up at 7 AM at my doorstep ready to rock â nâ roll. Ish and General Sir good morning and put down flooring cloths and they continue to do the install even in the rain. These guys worked hard and Iâ m excited to use my new Wi-Fi thermostat. They even help me and was patient enough to set it up the WiFi thermostat because I forgot the password and the installation is Came out perfect way better then I expected. Definitely recommend them.! Ask for ISH!!!!! Thanks guys"

"The men were very professional and fair. They tried very hard to fix the AC but the unit was deemed beyond repair. It was leaking coolant somewhere. They said they could give me a very good deal on a new AC with all parts and labor included if and when I choose to replace the AC unit with them. Even though the unit was not fixed because it was frankly beyond repair, I am still satisfied by their dedicated effort, honesty and professionalism. I will most likely buy a new AC from One Hour AC of Naperville in the near future."

FAQs for air conditioning projects in Montgomery, IL

Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.

Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.

Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.

Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.

Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
