Pressure Switch

Pressure switches are safety devices designed to ensure that HVAC systems are not damaged by high or low pressure caused by the compressor and/or the refrigerant’s heat transference process. Located on the condensing unit in air conditioning and heat pump systems, pressure switches automatically stop system operations when they detect high or low pressure. High pressure switches typically stop the compressor circuit and need to be manually reset to start the air conditioner or heat pump. This is to ensure that the potential problem is properly addressed. High pressure is most often caused by a bad condenser fan motor, dirty or damaged condenser coils, or blockage of the refrigerant. Most low-pressure switches reset themselves if normal pressure resumes. Typical low-pressure causes include refrigerant leak, blower motor failure, air flow blockage, and plugged evaporator coils.

Trusted Company


Cool Zone, Inc. is a company one can trust to have their mechanical work completed. The work was scheduled and performed exactly as stated without any delays or complications. The installers maintained my residence very neat and clean during the entire time of the new A/C installation. After the installation was completed they guided me through the thermostat settings and initial setup. They also assisted me with acquiring the Lennox App for my smart phone and instructed me on how to use this app. Cool Zone is a company I can truly recommend to anyone needing mechanical work.

Always Honest


Cool Zone has always been honest with me. I have used them for 15 years for all my properties. They have never over sold me on any product. Always up front with me choosing the best system for my needs.

Confidence in Cool Zone


We recently bought a 27 year old house that had less than consistent performance from the 3 central air conditioner units. Cool Zone came in and provided us with state of the art Lenox units and completely replaced the old deteriorating duct work. Our home is now much more comfortable and we have confidence in the performance of the equipment and the service provided by Cool Zone.

Many Thanks


Since I was a Dealer / Salesperson / Manager in a different industry I know what matters. And the Owner of Cool Zone does what few people do these days. “Build a great organization”. One of Cool Zones inside staff mentioned how wonderful the company was she worked for- well it just ran up hill from there. Sales, service call, installation, paperwork, filing warranty and rebates= All better than any purchase I have made in Years “61 years in fact”. I just wish I worked for a company like Cool Zone. Many Thanks – See you soon!

Like a Good Bottle of Wine


We have been using Cool Zone now for a number of years, and feel they get better with time, bit like a good bottle of wine. The knowledge, service, product knowledge is excellent and would recommend them to anyone.

Would Recommend


Shaun Silverwood, the salesperson who bid the job for a complete replacement of an existing system was very professional, and the installers were courteous and efficient. Would recommend Cool Zone to others.

So Happy


We are so happy we went with CoolZone. Our A/C stopped working and they fit us into their busy schedule right away. Their pricing was fair, their staff was great and the job was well done. We are very pleased.

Exceeded Expectations


Cool Zone Inc recently installed two new Lennox high efficiency AC units in our new home. They were extremely knowledgeable, professional and responsive to our needs. Before, during and after the install, the level of service far exceeded any of our expectations.

Dedicated Company & Staff


I used Cool Zone a couple months ago, and I am so glad I did! From when I first spoke with the office staff, to when the Service Tech came out to my house, I was overwhelmed by the amount of care, knowledge, consideration, and dedication this company puts into not only the work they perform, but their Company and Staff as well. I couldn’t be more pleased with my experience with Cool Zone and I look forward to using them in the future!
