Make sure that the company has the proper equipment and enough HEPA filtered vacuum power (2,000 CFMs or more), to properly clean your air ducts. Be weary of companies that use small vacuum units that have a small rotating brush on the end of a small vacuum hose with a typical airflow of 150 to 300 cfm or less. Proper air duct cleaning vacuums are negative air machines with 2,000 CFMs have 8 inch to 14 inch or larger, vacuum hoses to capture large quantities of dust and debris.
My A/C broke down so I called Waychoff's A/C to find out their terms and conditions and time frame for installation. It was really fast and professional service. I got price quite on front and installation took place next day. I have to say that installation crew Tim and Joe did very professional and attention to smallest detail job. It was very impressive. If someone interested - they provided military discount, 12 month financing with 0% through WellsFargo. Everything was done within 24 hours. A/C works good for now and it is very nice to have new one in our house. The garage unit is very quite!
I was lucky enough to have my AC lines clog up on a Sunday night. I called Waychoff's after hours emergency service and Erin got back to me within 5 minutes of my initial call. She was very friendly and explained different service options for my situation. Eric was my technician and was at my house within the hour. He was very knowledgeable, explained everything he was doing in detail, gave me tips and advice to help prolong the life of my unit and even let my dog crawl all over him and "help". He had me back up and running less than an hour after he arrived. If you want a company who knows what they are doing and has fast, affordable and friendly service, I would highly recommend Waychoff's!
"Energy is consumed by HVAC systems through a number of processes. Air is typically distributed through the ductwork via an electrically‐powered fan. Cooling coils remove heat from the air. Heating coils add heat to the air. Through normal HVAC usage, particulates in the air slowlycollects on the surfaces of various HVAC components, resulting in a gradual loss of energy efficiency. Some loss of efficiency via a single dirty component may be minor. When the loss through each component is added up, however, the impact could be considerable. Generally, the greater the buildup, the greater the energy loss. Removal of the buildup of particulate on HVAC components restores energy performance to the system."
