"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."

Heating Oil questions, answered by experts
There are three main types of heat pumps. An air-source heat pump system is the most common and has two parts—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’t need ductwork to distribute the air. A geothermal heat pump system pulls heat from the ground to help heat your home.
It’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.
Yes, geothermal heat pumps are worth the money. You can save about 70% on heating costs in the winter and around 50% on cooling costs in the summer with a geothermal heat pump compared to a traditional HVAC system. Over time, your savings on monthly utilities will pay for the cost of the geothermal heat pump installation. If you have an incredibly small yard, however, you may not have enough space for this type of system.
Geothermal systems provide energy efficiency, lower utility bills, and long-term sustainability with minimal environmental impact.
Regular inspections, loop flushing, and checking heat exchangers help extend system lifespan.
