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: Do services include eco-friendly options?

• <div><p>Yes, many providers offer organic or eco-friendly treatments. Confirm availability with your contractor.</p></div>

Q: Are there downsides to using a geothermal heat pump for floor heating?

• <div><p>The most obvious downside is the high upfront cost of buying and installing one of these systems. Additionally, sometimes the system can take a longer time to heat than alternatives like a boiler. Also, if something goes wrong with the geothermal pump, repairs are often significantly more expensive than repairing traditional, above-ground heat pumps. </p></div>

Went without any major problems. Heater was attached to a water soft machine, one of the connectors broke and they bdid not have one, had to order and return to fix. This did not cause any problem, a bypass was made, and the heater was able to be used.

It was done as promised.I had checked out the different brands and this band has a good rating. What sold them is it was the best price for heating with air. We were replacing a propane heater and the air was basicly a bonus.

"We were Purl's customers for years for both our residence and business, including getting regular A/C and heater maintenance and replacing our units. In our home, they missed a leaking condensation line during the service that eventually led to water damage in two neighboring rooms (the water went into the walls and underneath the floors) and thousands of dollars in damage. In our business, they keep changing what is wrong with the unit and coming up with temporary fixes, all the while charging us more and more."
