I cannot recommend Full Service Heating & Air Conditioning based on my recent experience…read more I called for an after-hours diagnostic because my rooftop HVAC unit stopped cooling. Before the technician arrived, I explained that the unit had not received routine maintenance since our previous HVAC contractor retired and that the filters likely needed to be replaced. The technician spent short amount of time on-site before leaving. Shortly afterward, the AC worked for 10 mins and stopped working again. I called and texted the company, and they told me someone would return on Saturday. What concerns me is that no one informed me there would be additional charges for the return visit. I was never asked to approve another labor charge before the technician came back. The invoice ultimately included: * $195 diagnostic/trip fee * $97.50 labor * $260 additional labor for the Saturday return visit In my opinion, a flat-rate diagnostic should result in a complete diagnosis of the problem. Instead, the first visit failed to identify or resolve the issue, requiring a return trip that I believe was simply a continuation of the original service call. The invoice notes themselves indicate extremely dirty filters, dirty condenser and evaporator coils, and a high-pressure shutdown issues that were not communicated as a complete diagnosis during the initial visit. I am disputing these charges because: * The initial diagnostic did not resolve or fully diagnose the problem. * I was not informed or asked to authorize additional charges before the return visit. * I believe the billing does not reflect the service that was actually provided. Due to this experience, I have decided to hire another HVAC company and have asked Full Service Heating & Air Conditioning not to perform any further work at my property. I hope the company reviews its communication practices and billing procedures so future customers know exactly what to expect before additional charges are incurred.

In addition to the standard $169 diagnostic fee ( which is fine) they also charged me $55 to tighten a wire nut that went from the furnace to the thermostat. Tightening a wire nut takes less than 3 seconds! I called and questioned the bill as it was labeled as re-wiring with a minimum charge of 15 minites. I believe that should have been covered on the diagnosis and not have an addtional charge. I will be looking for a different company in the future
