Fuller Heating, Air Conditioning, Plumbing & Electrical installed my heating and air conditioning unit. Since that time they come out twice a year to do the annual maintenance. They are always polite and they know what they are doing. I found it very comforting that on this maintenance check they had covered their feet with booties and they wore personal protective equipment due to the virus. They also did social distancing. I want them to know that I appreciate them for standing behind their equipment and that I have referred them to my church for the HVAC needs. Well done!
