"This is an excellent young company whose owners are professional and responsible. They used to work for a large company that our old central air condo uses but unlike THAT company, these guys are HONEST and actually do the work at a fair price! I called 8 other companies and had 2 other companies to our condo and they did absolutely nothing except charge me for work that they should have done. Chris and Steve did all the maintenance and cleaning work on 4 central air units and discovered a ticking time bomb in the master bedroom right over hubby's work closet. The overflow sensor was not working, and the pan was full to the lip and would have ruined everything in the closet and the teak floors below. These guys will be back on a regular basis with us and hopefully our condo association will be open to spreading the word amongst the residents who are getting ripped off by the other companies who are often here."

"Great Guy, Excellent Service, Quick, and Affordable. I chose this company to clean 3 a/c units as part of my move out inspection for my rental. They emailed me right away with a quote and even price matched. The guy that came out was super nice, explained what he was going to do and even provided me with an invoice with multiple pictures. I'm really glad I stumbled across this company. They made the move out process so much easier."

"Jae was professional, friendly, and incredibly knowledgeable. He quickly diagnosed the issue as a faulty fan, explained everything clearly, and ordered the necessary part right away. As soon as the part arrived, Jae called me to schedule the installation and had my AC back in top shape in no time. His efficiency and dedication were impressive, and he even took the time to inspect the entire system to ensure it was running smoothly. Highly recommend JK AC Service."

Heating and Air Conditioning FAQs, answered by experts

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.

In most cases, you should hire a professional to carry out services on your HVAC system, as the components are complicated, expensive, and potentially dangerous to work with. However, there are a few things you can do on your own to keep your HVAC system in good condition, including changing your filters every three months, keeping the area around your outdoor condenser clear of debris and plant growth, making sure your or intakes aren’t blocked, and keeping an eye out for increased energy bills, strange noises, and unusual odors related to your equipment.

To keep a window air conditioner in good working order, you should clean the filter regularly, inspect the seals, and store the unit properly during the off-season.

A power outage can damage your air conditioner, just like a power surge can damage any electrical device or appliance. In most cases, your circuit breaker or built-in surge protection on your AC unit protects your AC and just needs a reset. But in other cases, it might be that your AC compressor or capacitor was blown during the power surge. You’ll need to have an HVAC professional repair or replace any AC parts. 

You can adjust uneven airflow in your home by adjusting the dampers on the vents. However, if the temperature feels consistent throughout the home, don’t worry too much about uneven airflow. Generally speaking, larger rooms should receive more airflow than smaller rooms, especially if they only have one vent.
