Q: Do services include refrigerant checks?

• <div><p>Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.</p></div>

Q: What are alternatives to a misting system?

• <div><p>An evaporator or swamp cooler is a common alternative for small spaces. These coolers blow moist air into a space to help cool it down. They are more affordable than misters and use much less water. However, coolers will not have the same cooling effect as misters, cannot help plants survive the heat, and only reach a small area.</p></div>

Q: What types of heat pumps are there?

• <div><p>There are three main types of heat pumps. An air-source heat pump system is the most common and has two parts&mdash;an indoor air handler unit and an outdoor heat pump unit. A ductless heat pump system functions similarly to an air-source heat pump system but doesn&rsquo;t need ductwork to distribute the air. A geothermal heat pump system pulls heat from the ground to help heat your home. </p></div>

Q: Should you run an ERV system all the time?

• <div><p>It&rsquo;s a better use of energy (and your money) NOT to run an ERV system all the time. Most experts recommend that you cycle your ERV system on and off throughout the year. However, the recommended advice could change based on your climate, the number of people in your home, the size and style of your home, and your heating and cooling system. Contact a local pro for more specific advice. </p></div>
