"Jose and his crew replaced my existing single phase system with a new variable speed system that is quieter and more energy efficient. Jose's quote was the least expensive of four offers I received for similar 3 ton variable speed systems. They got me on their schedule within two business days after I agreed to move forward. The installation took a bit longer than I or they expected, but they got it done and did not charge any extras. On the second day the system wasn't cooling as expected. I let Sherman (the technician who installed it) know and he came out the same day to address the issue. He made the fix, admitting that he had wired the system for a different 14 SEER rating when it was a 16 SEER one. I've had no issues the past week and I am very happy with the new system. I will be using J and Andy's to service my other system, and I would definitely recommend them."

He also provided valuable, unbiased advice on different AC systems, focusing on what made sense for our needs rather than potential sales.

An evaporator coil is the chilled indoor coil that pulls heat out of your home’s air. As warm air passes over it, the refrigerant inside absorbs the heat and sends it outdoors, leaving cooler air behind. When the coil wears out or leaks, you’ll notice weaker cooling, higher bills, or even small puddles of refrigerant around the unit.
You’ll know an evaporator coil is on its last legs when airflow turns weak, the air feels lukewarm, or your energy bill suddenly spikes. Short cycling, hissing sounds, and visible refrigerant leaks are other red flags. Acting quickly keeps the repair bill smaller and prevents a full system breakdown, so call an HVAC pro as soon as you spot these issues.
With routine filter changes and a yearly tune-up, most evaporator coils last 10 to 20 years. Heavy summer use, skipped maintenance, or corrosive indoor air can shave years off that span, while a lightly used, well-kept system can reach the upper end. Staying on top of simple upkeep is the best way to protect the coil’s lifespan.
