"HIGHLY RECOMMEND! Did much research on companies 1st b/c I was aware of scams with duct cleaning. But this company is very legitimate professional - techs and receptionist, all the way around! Top quality service! On time and will answer any questions and explain it all in great detail? very polite and professional. And yes, they will take photos throughout if you want to see exactly the differences of before and after. I had bought a 1959 home which had never been cleaned. See my before/after photos. Before, I kept having to wipe off my counter tops a few times a day because they always felt gritty. After the duct cleaning, they stay clean now - A HUGE DIFFERENCE! The guys were awesome and went above and beyond by also helping me carry a heavy appliance from upstairs to my basement. Very nice guys! They cleaned up any mess before leaving, like they had never there. You will not regret using their service. Lower Price than others too! Thanks Danny & Cameron! Great Work!"

"My technician Keith was great. Friendly and super informative. Also too a quick look at the entire drainage system and gave my an idea of where problems will pop up the future without preventative measures (my home was built in the 50s and while the previous owners took really good care of the house nothing has been gutted and replaced yet)."

Heating and Air Conditioning FAQs, answered by experts

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.

You might notice that your air conditioner isn’t running as effectively as it once did. Specifically, your AC unit could take longer to cool your home, or it might struggle to remove humidity from the air. Higher utility bills and hissing sounds coming out of your AC could also indicate a leak.

Yes. Your air supply should be balanced. The return and supply ducts need to maintain that balance, and this only occurs because an equal amount of air should be entering and leaving your HVAC system. Changes in pressure, extreme weather, and blocking vents with furniture or your stuff can make the air supply unbalanced and cause your home to get too cold or hot.

There are a few things you can do to make your AC repair technician’s job easier and your home more comfortable while you wait for AC repair:

  • Cut back trees, shrubs, and weeds around the outdoor compressor 

  • Clear a pathway inside and outside to your AC components

  • Set up a ladder for attic access if necessary

  • Pull your window AC out of the window and place in an easily accessible spot

  • Supplement with fans and open windows to help keep your house comfortable

A dirty AC filter can lower the efficiency of your system, so depending on how dirty it was, you may notice a temperature difference when you clean your filter. You can try other solutions if your AC isn’t blowing as cold as it used to. You can call in a local HVAC tech to make sure everything is running correctly, fix your air seal if it’s a window unit, and clean your coils.
