What our customer's are saying about us..
"O'Brien replaced a 22 year old split system heat pump for us. Their company is outstanding as they, 1. Return every phone call or email promptly, 2. Responded to an email request for a service call on a Sunday within 30 minutes, 3. Their technicians and installers are knowledgeable, professional and extra neat, 4. Days later, a minor, unforeseeable problem with a PVC discharge pipe in a wall was fixed immediately. Their customer service is outstanding".
