The crew at Redi-Heating and Air Conditioning has great industry knowledge with equally as wonderful installation and service skills. Whenever we've needed something they've been there. They've replaced radiators in the living and dining rooms, installed a new furnace and water heater. We even sent them pictures on a weekend for a phone diagnosis and when there was no easy solution they showed-up the next morning at 8 a.m. Thankfully they have been servicing us since 2003 and we look forward to staying cool in the summer and warm in the winter with Redi-Heating & Air Conditioning by our side.

With Redi-Heating & Air Conditioning we feel comfortable, safe and trust whatever they think we should do to stay warm or keep cool in our home. We feel more like friends then customers. One time we had a problem that wasn't related to what they do and they came out to help anyway. We have been so impressed as no other company we have ever used has taken their service so personal. We always know who is coming and don't have to worry if we have to leave the house with them working. Thank you Redi-Heating & Air Conditioning, we appreciate you so much and recommend you to our friends.

I have been using Redi-Heating and Air Conditioning since 2003 for all of my Heating, Air Conditioning, and Boiler repairs. I have always found them to be accessible and quick to respond to my needs – whether it's during regular hours or 10:00 on a Saturday night. Their service people are both courteous and professional at all times. I would highly recommend them for all of your HVAC needs from installations to regular maintenance.

Back in 1991 we purchased a home whose prior owner had started to install baseboard heat in the basement but didn't finish the installation. After considering other companies we chose Redi-Heating & Air Conditioning and it's been over 20 years and we're still using them today. Their service is excellent, the crew is great and they even answer the phone at all hours and it's not an answering service. We recommend them and trust what they recommend to us.

"I have used Redi-Heating & Air Conditioning since 1961 and am delighted with their service. I wouldn't think of hiring anyone else and recommend them to anyone."
—Mrs. Magnifico, Arlington Heights

"Owning rental property has presented quite a challenge for us ever since 1925 when my dad built what was considered the most modern building for its time in the Northwest Suburbs. It has always been a priority for us to make sure our tenants are warm in the winter. We started using Redi-Heating & Air Conditioning around 1972 to install and maintain our boilers and as soon as we called, they would come right out. We even referred them to our 90-year-old neighbor who had air conditioning installed for the first time in her life! They are experts in their field and their whole crew is great. They have always made us feel like family and we will continue to use them for all our heating and cooling needs plus, we will keep on recommending them!"
—Mr. Busse, Mt. Prospect

"With four furnaces and three air conditioners, we really needed someone we could trust and Redi-Heating & Air Conditioning is AWESOME! They do excellent work, are easy to work with and completely dependable. Since 1995 we have never been too cold or too hot. They are always fair with everything they do and we would never use anyone else."
—Mrs. LaRocca, Park Ridge

"Great service, always helpful and prompt and we've been a Redi-Heating & Air Conditioning customer since the early 1960's. At first we used them for just for our home but later we bought a car wash in Streamwood and they've taken care of all our heating and cooling needs for both our home and business. When ordering parts they even come back the next day. They have always been fair with us and I never have to worry about their prices. That is why I recommend them to my family and friends!"
—Mr. Kleiner Jr., Algonquinn

"In 1982 we decided to enclose our patio so we put in baseboard heat with Redi-Heating & Air Conditioning. We had an existing similar system and Redi took over and never let us down. In fact, one year they showed up on Christmas Eve when we had no heat. Since the early 1980's they have been there for us. We are really pleased with everything they do and would recommend them in a heartbeat!!"
—Mr. Smythe, Park Ridge

"Back in the late 1950's Redi-Heating & Air Conditioning put in our first boiler. Throughout the years they've shown up when we've had no heat no matter what day it was, they've serviced our boiler every year and have even replaced it again. I know I'm in good hands with them, they're like our family and I wouldn't trust anyone else and neither would the rest of my family."
—Mrs. Benson, Arlington Heights
