Winston Water Cooler, LTD was originally established in 1963 by Al Winston as Winston Water Cooler Company. The core business was selling and servicing water coolers and fountains in the DFW metroplex. In 1992 Mr. Winston sold Winston Water Cooler Company to Roy Ferguson. The company was renamed to Winston Water Cooler, Inc. At that time, the company added water purification to the line of products. In June 2000, Jane Butter purchased the assets of Winston Water Cooler, Inc from Mr. Roy Ferguson and formed Winston Water Cooler, LTD. Since 2000, Winston Water Cooler and our Family of Companies have expanded to over 55 locations in 6 states and over a dozen different services and over 600 employees.

Heating and Air Conditioning questions, answered by experts

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

Good news: Your AC system doesn’t need Freon (a popular refrigerant) added regularly, if ever. Freon only needs to be added when there’s a refrigerant leak; however, it’s not uncommon for a gradual leak to occur every 5 to 15 years. Signs of a refrigerant leak include higher utility bills, increased humidity in the house, weakened AC performance, and a hissing sound from the system.

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.

The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.
