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.

Details: Repair • Only warm air is blowing from the vents • Closet • Roof • Townhouse

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.

Keith and his team worked late, professionally and diligently to make our boiler and hot water replacement as painless as possible and kept us informed every step of the way. We appreciate his hard work, innovative solutions and competitive pricing. We wouldnt hesitate to work with him again or recommend him strongly to others.
