I am preparing my home for rental and have a long list of services to arrange and chores to do. I messaged five HVAC businesses through Yelp, looking for annual maintenance for furnace and A/C, and Logic HVAC was the first to respond. He had a team of technicians at my house less than a day later. They worked quickly both inside and outside and got the job done for a reasonable price — no upsells, no surprise extra charges. I will use Logic HVAC again.
