Commercial HVAC Service in ILQuestions to ask HVAC contractors Continued;

5. Does the company have a physical address?  Many fly-by-night heating and cooling companies and uninsured moon lighters rarely have a business address. On the other hand, most stable HVAC companies operate from an office or shop facility, not out of a home office.

6. What is the standard company and manufacturer guarantee?  Not only will a better guarantee give you a longer peace of mind, better guarantees are usually offered by better companies

7. Does the company offer financing?  Even though you may not need financing, you should still look for companies that offer financing because it shows their concern for affordability and whether the company can meet the financial qualifications necessary to offer financing.

8. Does your company perform Manual J design calculations?  Good companies perform engineering calculations based on the Air Conditioning Contractors of America (ACCA)”Manuel J” to insure the equipment they provide is the right size. (Over sizing an HVAC system is just as bad as under sizing one). Improperly sizing HVAC systems are all too common.

9. Does the company follow proper matching of components?
When you are replacing an air conditioner or heat pump or other major components it is important to replace both the outdoor unit as well as indoor components together as a matched set, if not matched you get a reduced efficiency and increased breakdowns. Good contractors insist on properly matching to insure maximum efficiency is achieved.

10. Does the company offer you choices?  With today’s technology there’s a wide variety of options available for heating cooling and ventilation systems. Reputable companies will present you with choices in product efficiency, features, filtration, controls, and financing, as well as custom HVAC design and implementation.

11. Does the company provide customer testimonials?  Professional HVAC contractors such as American Services HVAC repair in St. Louis, should be able to willing to readily supply any number of past customer testimonials.
