I recently completed a job for a customer who needed a new air conditioning and heating system. The customer had a 3-ton a/c unit and a 5kw heat strip that needed to be replaced. I provided the customer with an estimate for the job, which included the cost of the new equipment, installation, and any necessary permits. I also provided the customer with a detailed breakdown of the work that would be done and the estimated timeline for the project. The customer was very pleased with the estimate and decided to move forward with the project.
