"I had a Trane A/C installed by air systems. Carlos and his crew were on time, worked very efficiently and finished the installation within 1 day despite having to widen the attic opening. They cleaned up carefully and were professional in their communication. Also, their price was about $1000 less than the closest competitor. Would definitely hire them again!"

"Do not trust this company or its owner Roberto Quiros. I hired him to install new commercial equipment which has been a nightmare. I gave him 50% as an advance and it is important to mention that when it comes to collecting payments he is super punctual but when it comes to finishing the job he is terrible. He does not answer the phone, when he does answer he makes commitments that he never fulfills and literally you have to be chasing him so that he fulfills what he offers , he does not deliver equipment on time and of course he does not finish the job. He is an irresponsible and unprofessional fraud. I have to hire someone else to finish the job. USA AIR and ROBERTO QUIROS ARE NOT TRUSTWORTHY."

A geothermal heat pump system will take about 10 years to pay for itself, and it has a life span of anywhere from about 25 to 50 years. Installing a geothermal heat pump will cost about $14,250 upfront, but it can reduce your energy bills by around 65% when compared to a conventional HVAC system.
HVAC systems usually last between 10 and 30 years, with most having a lifespan of around 20 years. Factors that impact a unit’s life expectancy include which brand you choose, how often you use it, and how well you maintain it. To make sure yours lasts as long as possible, make sure to keep it clean and schedule an annual service with an HVAC technician.
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.
