Our Mission & Values

Owner Image

Hi. I’m Joseph Kohn, owner of Scientific Air Conditioning. Don’t invite just anyone into your home. Feel free to call and talk to me until you’re comfortable. I even welcome callers looking for free advise over the phone. I’m here to serve YOU.

Many technicians claim to be qualified. But do they have the credentials to prove it? Here’s my report card for the NATE A/C and Heat Pump Test.

Honesty & Integrity

I give you my personal promise that I will treat you according to the Golden Rule and will never lie, bait & switch, or pressure you into buying something. I will always arrive at your door in a clean uniform and protect your home from dirt and damage while I’m working. I will take the time to explain things clearly and answer all of your questions.

Fair Prices

As a small company with a mininum of overhead, I can charge less than many larger companies. And because I give upfront pricing, you know the exact price before I do any work. No surprises.

Technical Expertise

As a NATE Certified Technician, I don’t guess what’s wrong with a system. I perform complete analysis and diagnosis with an understanding of the “science” behind the operation.

Satisfaction Guaranteed

Watch me work. I’ve been specializing in residential system troubleshooting, repair, and replacement for over fifteen years and participate in ongoing training. I don’t take shortcuts or put “bugs” in your system. Therefore, I’d be happy to have you watch me work.


"We've called Scientific A/C twice, once because we had no hot water and once because our A/C stopped working. Both times Joseph came the same day and fixed the problem. He also installed a different type of filter. Now the house is less dusty and the filter is easier for us to change. Thank you."
—Tim & Lori in Lewisberry

"Since converting from oil heat to a heat pump we're spending less on heating costs."
—Bob in Camp Hill

"Another company installed a new heat pump and then came out 3 times because our electric bills were $500 a month. They told us that's normal. I called Scientific A/C and Joe quickly diagnosed the problem as a wiring mistake and fixed it. Now it works as it should."
—Harold & Margie in Manheim
