I had a issue with the blower motor on my furnace. Upon inspection Keith pointed out additional problems he found helping me see and understand what was happening. The furnace was over 20 years old so I opted for a replacement. Since he was doing this work i also asked him to add a whole home humidifier and uv light to our system. He was professional and prompt the entire way through and I’m very happy with my new furnace. I would highly recommend Lascos heating and cooling to others out there looking for help with their HVAC needs

I requested at 7pm for broken AC with a newborn and he offered to come that evening even though it was 9am. Got everything fixed for us quickly even though it required being on a 3rd story roof in 90 degree heat. And was kind enough to throw in installing our smart thermostat with the compressor repair.

Keith was excellent and worked with us on scheduling for special needed timing. His price was more than fair and he was timely and professional. Job was done to exact specifications. Highly recommend his service and will call him for future service.

Really great. Upfront and professional, and he was nice. He didn't try to upsell us things we didn't need. Will use him when we need to replace our system.

I highly recommend Lasco's Heating and Cooling for your HVAC needs. My furnace stopped working in negative temps and Keith Lasco assessed what was going on, was able to fit me in between appointments and provided a quick fix to my heating issues.My furnace was quite old and he shared all the details and my options for a long term fix. My furnace was replaced on the same day. Knowing that many people were experiencing issues due to the weather, it was an added relief that time was taken to ensure I was not freezing in my home and that my furnace issues could be resolved so quickly.I will definitely be using Lasco's in the future and I recommend them for your HVAC issues.
