I am a professional HVAC technician with over 10 years of experience. I recently completed a job at a customer's home in the city of New York. The customer had a problem with their heating and air conditioning system. I arrived at the customer's home and assessed the situation. I found that the customer's heating system was not working properly. I diagnosed the problem and provided the customer with a detailed estimate for the repairs. The customer agreed to the estimate and I scheduled the repairs for the next day. I arrived at the customer's home the next day and completed the repairs. The customer was very satisfied with the work and I received a positive review from the customer.
