Choosing The Right Company

The following questions will help determine if they are a quality service company or not.

1. Has the company been in business 10 years or long enough to develop an established record of accomplishment and dependability?
2. Is the company locally owned and independently operated?
3. Does the company have an office and its own equipment and material warehouse?
4. Is the company licensed and bonded? Do they apply for the proper permits and necessary third party inspections?
5. Does the company only hire competent, caring and dedicated people with a commitment to quality and excellence, teamwork and the service of its customers?
6. Does the company perform criminal background checks and registered sex offender inquiries on all of their employees?
7. Do employees undergo drug testing with a no tolerance policy?
8. Are the technicians continuing their education with ongoing training?
9. Does the company forbid the use of subcontractors for installations and service except as required by scope of work or by licensing, permit, code or inspections?

If you did not answer YES to each of these questions about your current PHC company, consider switching to a quality company for all of your needs.
Some decisions are just too important to leave to chance!
