Our technician (CWigington) and his partner showed up on time and completed our HVAC winter maintenance. After the maintenance, they pointed out hazardous build-up of mold/bacteria in our attic HVAC system. This was the first time this was brought to our attention. They were able to fully clean the system and install a Halo-LED purification system during the same visit. Both were extremely courteous and professional during the visit. They advised on how we could get additional discounts and extend our Halo-LED system warranty. Thankfully (and unfortunately), they also notified us of captured rodents in our attic traps.
