    I have used their services three times now. Each time they are quick, efficient, reasonable and go the extra mile to educate me about the issues and what I need to do whether it is now or further down the road. I have young children and I had my heat go out in the evening. They responded quickly and were very helpful to get me back up and running. Dylan has been my service tech each time and he is very, very good! Highly recommend them

    SOOO! WOW!. Furnace decided to not continue heating the house. I Called. Dillon showed and fixed the furnace, Maybe 30 minutes. 1 hour total. And at a fair price. I was glad to have him in my home. It'll be 20 degrees tonight. Don't need the pipes bursting. Thank you L&L Heating and AIr. I greatly appreciate the professionalism, kindness and efficiency. I've used L&L at other homes and will continue to call you for great service. Keep up the good work. Jennifer, another warm customer.

    I had a new air conditioner and furnace installed at my condo. The sales rep was great, but the actual experience of installation was a bit of a mess. My furnace didn't pass inspection from the city, so the crew had to come out again to fix it - then it passed. And then less than a week later, I had no heat due to the safety switch on my furnace not working properly. Thank goodness for a warranty, but it doesn't make me feel great when I've already had issues this early on.

    I had a great experience with this company. My installer was great and my new furnace and A/C work well. They have a great warranty, and when a former employee made a mistake, management took care of it without hesitation.

    Larry’s team did an excellent job for my broken water heater. Service guy came to my house and found the problem, he decided to replace the water heater next day since it is still under manufacture warranty . I am very happy about the very responsive service .

    Jordan Carrier, and the install team were very professional and polite. The 3 man team arrived on time. They covered the work area with tarps to ensure no damage was done to the flooring .... very clean. They explained the use of the new thermostat and provided other tips about the AC and humidifier. They were in and out in about 3 hours! I would recommend L & L HEATING and AIR CONDITIONING to anyone who appreciates GOOD VALUE and GREAT CUSTOMER SERVICE. Linda H. - Colorado Springs

    L and L Heating and AC replaced my 20 year old furnace. They were reasonably priced and did quality work.
