When Should You Hire an HVAC Contractor?


Generally, HVAC contractors or HVAC technicians work with or run companies that repair or install heating systems and air conditioning units for homes. But they have specialized services too. For example, if you are a wine collector and you are thinking of installing a wine cellar in your Collinsville, IL home, you might hire a Illinois HVAC professional who specializes in refrigeration work.

HVAC professionals can use their skills to help you to save money on your Collinsville, IL home’s energy bills by installing radiant barriers in your attic or split-zone heating and cooling systems to heat rooms like solariums while cooling upstairs bedrooms during warmer temperatures.

If you or a family member suffers from allergies, you’ll want to find a Illinois HVAC technician who is knowledgeable about the latest cooling and heating products that include antiallergen filters. Contractors who work in the HVAC industry keep up on the latest in heating and air conditioning technology so outdated or troublesome systems can be retrofitted with newer, more energy-efficient models. Some of these professionals may work with your contractor, builder or other home improvement professional to get the job done.



Ask HVAC contractors about these residential heating and cooling technologies:


  • Tankless hot-water pumps
  • Residential air cleaning devices
  • Ductless air circulation systems
  • A desiccant enhanced evaporative air conditioner system (for hot and humid climates)
  • Heat recovery systems (which cool the air and heat water with no extra energy use)
