Purchase, Install, Peace-of-Mind

A few considerations come into play while deciding between repair and replacement. If you’ve spent money on repairs in the last several seasons, your ten to fifteen-year-old system is probably due for replacement. Maintaining an old furnace and air conditioning will cost you money in the long run. 

Installing a new, more efficient commercial-grade HVAC unit is an investment in your company’s future. Furnace annual fuel usage efficiency (AFUE) has improved significantly in the last 30 years. Retrofitted 1970s furnaces systems run at roughly 65% efficiency, whereas some newer models run at 100% energy efficiency. For commercial cooling systems, the Commercial AC installation and maintenance pros at Astro Heating & Cooling will extend the lifespan of your AC unit well beyond the average ten years, saving you money on energy and helping the environment too.




All these types of commercial heating furnaces and air conditioners are frequently installed, repaired, and maintained by the Astro Heating & Cooling team.:
