My name is Amanda Delgado and I am representing Evans Cool Solutions, a local Tucson HVAC business. Our owner, Joshua Evans has 20 years experience in the field of heating and cooling. He has owned Evans Cool Solutions for almost 13 years. He started out with one tech working out of his Tacoma and now has a tech and two fleet vehicles. We enjoy many returning customers but are also working on expanding and making our small family owned company into a larger business. Currently, most of our jobs are residential with the occasional commercial job as well. We are open to serving all of Tucson and can go to Vail or Benson etc. As most of you know I started out as a teacher for over 16 years. I am currently working with Evans Cool Solutions for almost 2 years and am excited to use my experience in customer service and communication. I am a lifelong learner and today I would like to pump you up. That’s right, my presentation today is all about heat pumps.
According to Wikipedia, a heat pump is a device that consumes energy, usually electricity to transfer heat from a cold heat sink to a hot heat sink. In simpler terms, it transfers heat rather than generating it. This makes it more energy efficient than just electric heating. It uses compressed refrigerant the same way a conventional air conditioning unit works. Actually, a heat pump unit is identical to a conventional unit with a couple added parts like a reversing valve and accumulator.
The reversing valve does exactly what its name implies. It reverses the flow of freeon. So, a heat pump is air conditioning running in reverse. The way this works is with components called thermal expansion valves. These components are responsible for compressing and releasing freon. When compressed, freon gets cold but gets hot when it expands. In all heat pump systems, there is an outdoor and an indoor coil. (condensing coil and evaporative coil. Depending on which way the freeon is flowing, it will disperse either hot or cold from the outdoor coil and transfer it to the indoor coil through the freeon.
Some conventional units use an accumulator but all heat pumps use an accumulator. An accumulator is responsible for keeping liquid out of the compressor as well as collecting and storing excess refrigerant. It also removes moisture and debris as well as regulating efficient flow of vapor freeon.
Some people confuse conventional air conditioners or mini splits with heat pumps. However, a conventional air conditioner is only able to cool while a heat pump has the capability of heating with the same freeon system. Conventional air conditioners are most used in homes that are supplied with natural gas or propane for heating. Heat pumps come in a couple different styles of equipment residentially. More common of the two would be a central home unit. They also come in ductless minisplit units. These mini splits are good for garage conversions or added rooms to residential projects.
One important thing to remember is like with anything else, it is best to have an annual wellness check to keep your heat pump working at it’s best capacity. Evans Cool Solutions recommends getting your unit checked twice a year. A winter check is 115.00 for one unit and 50.00 for each additional unit. It will check for things like air flow, run caps, gas pressure and flames etc. A summer check is also 115.00 for one un it and 50.00 each additional unit. These checks include checking the thermostat, wiring, coils, fans etc. However, we also offer service agreements. Our service agreement is 250 dollars for a wellness check with one unit. In addition to the wellness check, customers get to enjoy priority scheduling which means if something happens to your equipment, we have 24 hours to respond. The diagnostic fee of 95 dollars will be waived. We also remind you of when it is time for your wellness check. Evans Cool Solutions also offers plans for two or more units. Give us a call to discuss our service agreements.
I really enjoyed telling you about heat pumps today. Like always, I learned a lot but am not a tech. Please call to find out more information.
