It was actually hotter in the house than it was outside. Steve was able to come over same day, and about 20 minutes later, it was starting to cool back down. He did a great job of explaining what he had done, and how I can make sure that the AC is running at peak efficiency. Thanks Steve! - Barry, September 2018 (Google)

Air conditioning was not working, assessed my problem in a matter in minutes and fixed it. Professional, knowledgeable and very reasonably priced. I would highly recommend this company. First experience was very pleasant, I will use this company again. - Jeanne, June 2018 (Google)

The best service I've had. Steve came out after hours and did all he could to get my unit going. He seems very honest and definitely not trying to sell you more than you need. - Jennifer, June 2018 (Google)

Steve, and his crew, were very professional, clean and friendly. They had my HVAC problem solved quickly, within three hours. Just in time for the hot and humid weather. I definitely recommend them for your HVAC needs. You will be happy you chose them. - Bill, June 2018 (Google)

Our air conditioner stopped working on one of the hottest days that we had a week ago. I called Steve and left him a message and he texted back promptly to let us know that he was at another job but would come asap. He was able to come at 8pm and stayed until 10pm to fix the issue. It was a pin hole leak which had left our unit with very little coolant. He was able to fix the hole and fill up the unit with coolant. I am so thankful to him and our unit is working better than it has in a long time. We also used him to replace a unit in a condo that we own. He is very professional and gets the job done. He is very reasonable on his pricing as well. I will use him for all my HVAC needs and highly recommend him. - Pat, June 2018 (Google)
My AC was blowing warm air last week AFTER I had one of Cincy's "big name" repair/install tech's over-charge to "repair" it. Totally disillusioned w/ their "repair" I reached out to EFFICIENCY for answers. Steve explained how my current system was insufficient for my Condo's square footage, etc., and clearly explained my options. He then quoted me a new high quality system, which was almost half that of the quote I received from the "big name" player. Their install was quick, clean, and professional. Now I'm cooler and more comfortable than I've ever been in my Condo. If you're looking for an honest, professional, and CARING small company to get you back in comfort call Steve. He'll treat you RIGHT... - William, June 2018 (Google)
Steve was amazing at fixing my air conditioning problem. He was dedicated, professional and very kind. He explained to me in detail everything he was doing and also fixed any/all issues he saw. He even went above and beyond for me as a customer as he left, bought an additional tool & added freon for no charge! Going forward, I will call Steve for all my heating and air needs and I will suggest him to all my family and friends! - Tina, June 2018 (Google)
Steve was great. Willing to talk with me about what he found and not only fixed my heat pump issue, but also dug into the most likely cause and took steps to help prevent the issue in the future. Appreciate the service and will gladly call him again the next time - Ben, May 2018 (Google)
Efficiency Heating and Air is a 5 star business. Very professional, knowledgeable and personable. Arrived on time and didn’t waste any time getting started! Will definitely recommend to friends and family! - Wyatt, May 2018 (Google)
Very nice and professional. Always responds promptly when I call with a question or concern. - Melissa, May 2018 (Google)
Highly recommend Steve and Andrew. They were very quick to my call and completely replaced my AC Unit and my Furnace all in one day for a great price and a nice plus, they were great with my dogs!! - Madison, May 2018 (Google)
I was given Steve's name from a friend after waking up to no heat and a CO2 leak this winter. I called him on a Saturday afternoon, he came right over to check everything out. I really appreciated his quick response and he was very friendly and honest with me about what I was going to need. Steve gave a very very reasonable price to both my heat and air and he put it in immediately. He came back out to explain how everything works and just came out this week to get turn the sir on to make sure it is ready to go for the summer. I would highly recommend Steve Lynch if your are looking for a new heating and cooling system for your home. - Cheryl, April 2018 (Google)
Steve was referred to me by a relative after I had HELP! come out twice. Steve was very professional, showed up on time and was able to diagnose my issue in an hour! HELP! came out TWICE and spent HOURS and never found the cause. I was amazed by the knowledge he had, he really knows his stuff! It was a great customer experience and he didn't try to "sell" me things I did not need. He gave me tips on some things around the house to make it more efficient. I really look forward to doing business with him in the future. " No Quarter " 🙂 - Sarah, April 2018 (Google)

Our furnace quit early this morning. My husband called and they arrived quickly and fixed the problem quickly as well. Very reasonable price. They were very pleasant and helpful. Didn't try to sell us something we didn't need. We highly recommend them! - Stacey, January 2018 (Google)
It was one of the coldest nights of the year and our furnace stopped working. Steve was already home for the evening from work but stopped everything and came to our rescue. He was able to fix our furnace in a short amount of time and charged just a minimal amount. We are so thankful and will definitely recommend him to our family and friends and use him again for any heating and air issues. -  Mark and Sonya, January 2018 (Google)
Steve is a top-notch professional. He knows everything there is to know about heating and air conditioning. He gives great customer service and has gone out of his way on several occasions to fix my heater issues - Natalie, October 2017 (Yelp)
One of the best experiences that I have ever had with a Heating Air Conditioning company. Steve was on time, and called on the way. He respected our home and this pleased my wife very much. Install was flawless and for a tough job was completed in one day. It's hard to find companies that you feel like you can trust but that is not an issue with Efficiency Heating & Air, we will be using them for all of our maintenance in the future. - Johnathan, May 2017 (Google)
Efficiency Heating and Air Conditioning is a great company to work with. Everything was done professionally and Steve was excellent. He took time to explain everything about the system and was very knowledgeable and helpful. They were also the lowest of my 3 bids. I would highly recommend them to all my friends and family. - Ed, April 2017 (Google)
Very knowledgeable and explained our central air unit. Very quick. Had another provider out who said we needed a new compressor. He explained why they may have thought that. As a woman who has struggled with service professionals before, I like that he didn't treat me like I couldn't possibly know anything mechanical. Will definitely recommend to all our friends. - Natasha, June 2016 (Facebook)
Super quick response and very reasonable. Mr. Lynch saved our weekend. Will definitely let my friends in Loveland know about you.                  - Daevid, June 2016 (Facebook)
