    Our experience with L&L was a very positive one. The technician arrived early, which was good, and was very professional. He listened to my problem, checked out my concerns and did not find reason for unnecessary repairs. Very honest. The invoice report was also very thorough and explained in detail what he had done. The pricing was very fair and I would not hesitate to call L&L again for my heating and air conditioning needs.

    Aaron has been at my home twice. Always very nice and professional and on time! The follow up on questions with Aaron and the main office have been spotty at times, but I am persistent and keep calling. I was confused whether to deal directly with Aaron, or with office - that could have been explained better to me up front. I now have a bid that we are considering - thank you for working with us on the cost of the humidifier. Anne

    It was a good experience. The technician was on time, courteous and worked quickly. We needed a tune-up for a 5 year old, high efficiency furnace and he didn't try to sell me additional un-needed services. Thank You, Marcia

    Emergency service of a furnace on a cold morning. 8 o'clock call and service completed by 9:30. Fast, friendly, professional and cost effective. I will keep their number handy and recommend them!

    I had a great experience with L&L fixing my heating issues in my condo.Mickey initially came out to diagnose why my heat was no longer working. It was blowing out cold air. He spent a good solid couple of hours performing diagnostics and making sure he found the issues. He did a good job of explaining how my heater worked (It's a combo AC/Heat unit in the ceiling, the heat works off of it's own hot water loop from the water heater), and explained how the fan controller and water pump appeared to be the issues. He gave me a quote to have them return to do the work.I mulled it over a bit and decided to proceed. So a couple of weeks later, I had Marcus come out to perform the repairs. Marcus found that he did not actually have to replace the entire pump, and only needed to replace a cartridge. The fan controller still needed replacing, so he performed this work. Altogether, this brought the total down by $300 from what the original quote had been. I appreciate how honest Marcus was.Although the heating unit itself was fixed, it was still starved for hot water. Marcus did some more investigating and determined that there were corroded nipples (attaching pipes to water heater) and pipes on the lines from the hot water heater supplying the heater. As it is an extremely old water heater, he said he could attempt to replace the nipples and pipes but depending on how badly corroded, and the age of the hot water heater, no guarantee he could do so.Decided to at least give it a try. Had Marcus back out yesterday. He was able to replace the pipes and nipples, and he showed me the old pipes which were easily 95-100% clogged. With this repair, the heater is now working perfectly.I will be using L&L for any repair work needed in the future. I appreciate the honesty and integrity, their accurate diagnosis of the issues, and their care when they arrived, both wearing shoe covers while in the condo. Spending time to diagnose and perform their work, all while communicating to me, and teaching me about how the system worked. Reasonable pricing quotes that include parts and labor. L&L will be my go-to.

    Helpful, on time service rep showed me how to change the filter in my crawl space furnace. Showed me before and after photos of the cleaned unit. Showed me the power output of the motor that needed replacing, as well as the level of the new one.
