"Victor recently replaced my home AC unit. I have been using his services for many years. I have found his prices to be reasonable and the quality of his work superb. He does the work, not an apprentice or a new grad that you get with many other places. He has also always been quick to respond to emergencies, never longer than the next day."

"Mark and Serge were prompt, professional, and performed quality service. We were away when there was a problem with our AC units and they were able to work with our house sitters--and me remotely--to quickly get the AC up and running again as well as alerting us to an issue with our Nest thermostat. Panda is our go-to service for all our HVAC needs."

"Everyone was very professional. They came and looked around and took measurements for ductless mini split ac units. They gave me a reasonable price and finished all the work in reasonable time as agreed to. Everyone was prompt and professional. They did clean work inside and outside the house and cleaned up after themselves when were done. If I ever need anymore work done I would definitely use these guys!!! Units work great! They answered all my questions abs continue to answer them as needed. Only a text away! Highly recommend!!!"

"I had the equipment replaced, a brand new, super high efficiency, fancy, lovely stuff. It's a central air system, and it's Lennox equipment. It's high efficiency. You can get it for less than that, but you're not gonna get the high efficiency quiet and all that kind of stuff. I had received other quotes which were like more money for the same system. I have been using them since 1986. No complaints. They do their thing, and I can't fault them. I have a service contract with them for this."

Air Conditioning questions, answered by experts

If your AC condenser is nearing the end of its life, it might leak fluid or make loud or unusual sounds (like grinding or hissing). You might also notice that it isn’t heating your home as evenly or effectively as it once did. Also, an aging condenser will have to work harder to cool your home, which may force it to use more power and drive up your utility bills.

An air conditioner’s watt usage depends on multiple factors, including the type of AC unit, its size, and how often you use it. With that said, most central air conditioners consume between 3,000 and 3,500 watts. Meanwhile, window AC units use 900 to 1,400 watts, and portable air conditioners consume 2,900 to 4,100 watts.

No, you should not attempt to replace an AC evaporator coil yourself. This is a complex task that must be performed by a licensed HVAC technician. The process involves handling hazardous and flammable refrigerants, which poses significant safety risks. Attempting a DIY replacement can also cause further damage to your HVAC system and will likely void its warranty. It is necessary to hire a local AC repair professional for this job.

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.

The cost of R32 refrigerant is about the same as the cost of R410A refrigerant, the most widely available type of refrigerant today. However, R32 systems use about 20% less refrigerant than R410A systems, making the refrigerant less expensive overall.
