The company maintains 24-hour availability Monday through Friday, with Saturday service from 9 AM to 5 PM, providing emergency heating and cooling repairs alongside scheduled installations.
One reviewer discovered Gosal through the Carrier website and praised the technician's prompt arrival, thorough filter cleaning, thermostat replacement, and clear explanation of the unit's condition. Multiple five-star reviews highlight competitive pricing, same-day repairs, and meticulous post-service cleanup.
Reviewers describe specific positive experiences including a furnace replacement completed within days of the estimate, an air conditioner repaired in a single day, and a technician who returned to redo work at no charge. The negative review details a disputed insurance claim scenario that did not reach resolution.
