For this job I performed a heating tune-up. No significant abnormalities were noted during inspection within the heating elements of the unit. I didn't know that the homeowner had a UV bulb out of tolerance on a germicidal UV system. I offered replacing the UV bulb, upgrading UV systems to the iaq200 that also purifies air, and also replacing a drain pan that has severe corrosion inside of it. Homeowner did not commit to any work at the moment, I stated I would leave the estimates as open for reference in case they wanted to have any work done later down the road. Thank you for choosing Comfort experts, have a great day!
