I had trouble with my swamp cooler, called Pro-Tech, they set me up with an appointment quickly, service was fast and the service Tech was knowledgeable and courteous. I had my water line and filters replaced, right the first time and reasonable for the work involved. I am a handyman by nature but I'm not as fast and I tend to procrastinate, and I'm cheap so I just call Pro-Tech for my heating and air conditioning needs.
