Finding contractors to improve your air quality online can be a daunting process. However I have found that using listing directories makes your job much easier. There are home improvement and maintenance specific directories where you can find services to improve your air quality.
When you get onto one of these, get multiple quotes and compare them. There after choose your service provider or contractor according to their ratings and your budget. You will find services ranging from mold removal companies to HVAC contractors. Below I list some of the best directories where you will find service providers who can help you improve your air quality.
Find A Professional Odor Remover
A great place to search for odor removal companies in your state is at eLocal. Just enter cleaning in the search and you should get a list of cleaning companies that can also help get rid of odors in your home. Alternatively you can pick up the phone and call On Call 24. With On Call 24 you can ask for the exact service you need and the agent will direct you to the right company.
Find An HVAC Contractor
For HVAC contractors who can come in and clean your air ducts, or install a whole house air cleaner or humidifier, the best point of call is HVAC.com. You can also use eLocal and On Call 24 to compare quotes between the three platforms.
Find A Professional Mold and Mildew Removing Company
The easiest place to find mold and mildew remediation services is on eLocal or on On Call 24. Just go on their websites and follow their instructions. If you prefer to talk directly to some one rather than filling in forms online, On call 24 will be great for you. They even have an option for you to have them call you back.
Find A Flood & Water Damage Repair Contractor
Water damage and proofing contractors can be found on both On Call 24 and on eLocal.
Conclusion
For all of the above services and any other service you may require to improve your air quality, I highly recommend HomeAdvisor ProFinder. They are one of the biggest and highly reliable databases online where you can find an approved contractor for pretty much any household project including air quality control and improvement if you are based in the US.
