Which Is the Right Choice for My Home?
Choosing between air filtration and air purification depends on the specific needs of your home and family. If you or your loved ones frequently experience allergies, asthma, or other respiratory issues, air filtration may be a great option. It effectively reduces allergens like dust, pollen, and pet dander, helping create a more comfortable living environment.
If your concerns extend to eliminating germs, bacteria, or mold spores, air purification might be the better fit. These systems target microscopic particles and can even neutralize odors or harmful chemicals, making them ideal for households focused on fostering a truly sanitized space.
It’s also worth considering a combination of both solutions for maximum coverage. Every home is unique, and factors like existing air quality, the presence of pets, or health sensitivities can influence the choice. That’s why professional guidance can make all the difference. At All-Phase Heating & Cooling, our licensed and NATE-certified technicians are here to provide expert recommendations tailored to your home’s needs.

I had problem with my cooling system which was caused by the negligent work of the previous company that I had hired. Apparently, system malpractice is not rare nowadays. All-Phase sent over Evan to rescue us from our air conditioning meltdown. He was a young fellow, but sharp as a tack. He had an aire of professionalism and respectfulness which has become uncommon, as if he had stepped out of the 1950s. The reason I picked the company was because the website made it appear as if were operated by a good family. They looked trustworthy. I wasn't disappointed in my decision. My expectations were exceeded. There was basically a thicket that had grown up around the outside unit, so he had to fight his way through it, in order to get the job done. There was not one complaint. He did the job fast and well, while maintaining a positive attitude the whole time. Even the dog liked him, and "killer" doesn't like anybody. When everything was finally completed, I was pleasantly surprised by the charge. It doesn't seem proper to site numbers, but it was very reasonable, and considerably less than what I was accustomed to. I'll certainly call upon them again whenever there's a problem in the future.

All-Phase installed a new air conditioning system in August, First maintenance visit was today by Derrick. He was on time; provided ample notice, neat, appropriately dressed, very AND very knowledgeable and thorough.

All-Phase was very professional and knowledgeable, and they were able to resolve my heating issue the same day I called. I want to thank our technician Matt for taking the time to explain the process and to answer all of my concerns. If you are having heating or cooling issues don’t hesitate to call them.

Air Filtration vs. Air Purification
Air filtration and purification are both designed to improve indoor air quality, but they work differently to address specific needs. Understanding the difference between the two can help you determine which solution is best for your home.
Air filtration is primarily focused on trapping particles like dust, pollen, pet dander, and other larger airborne contaminants. Filters in your HVAC system or stand-alone units capture these materials as air passes through, effectively reducing common allergens and visible pollutants in your home. This makes air filtration ideal for families dealing with allergies, asthma, or other respiratory concerns.
Air purification, on the other hand, goes a step further by targeting microscopic contaminants, including bacteria, viruses, and mold spores. Purifiers often use advanced technologies such as UV light, ionization, or activated carbon to neutralize harmful pathogens and eliminate odors. This option is particularly beneficial for those concerned about germs or chemical pollutants in their environment.
