Should I choose Monster Vac to clean my HVAC system?

Our customers tell us that having their Heating Ventilating Air Conditioning system properly cleaned has reduced their household dust. We, at Monster Vac, hear from our customers about how their allergy and asthma symptoms have been greatly reduced by having Monster Vac clear their HVAC of molds and allergens.

Along with better indoor air quality come other benefits such as more airflow and better delivery of warm air and air conditioning, reduction in energy costs and money saved by fewer HVAC breakdowns.

The Innovative Marketing And Management Group did an industry study and found critical characteristics somebody looking for an HVAC cleaning company should include in their selection.

NADCA Certification: The National Airduct Cleaners Association The Company you select must be a member. Furthermore NADCA only requires that one person at the company be certified. You should demand that the person cleaning your system be certified. Monster Vac and all Monster Vac technicians are NADCA certified.

Cleaning To NADCA Standard: A company can be NADCA certified yet not clean to NADCA standards. They can cut corners even skip steps all together. Monster Vac does everything to NADCA standards. Make sure your HVAC cleaning company uses equipment that generates sufficient suction and can demonstrate they have the required pressure differential. You should also demand that your HVAC cleaning company uses clean sanitized equipment, and perhaps most important ….they clean your evaporator coil with a pressure wash.

EPA Technicians: The Company you select should be EPA certified and licensed to handle and recover refrigerants in case of a mishap. All Monster Vac Tech’s are EPA certified and licensed to handle and recover refrigerants.

Disassemble Plenum To Clean Coil: Make certain the company you choose includes the cleaning of your AC coil. To do this they need to remove the cover (plenum) to clean the coil. If they are not doing this you are paying for an incomplete an ineffective job.

Correctly Clean Your Coil: Make certain the company you choose, if they even bother to clean your coil does it properly. Taking a rag and wiping off the front surface of the coil is not cleaning the coil! They should clean all portions of your AC coil, both upstream and downstream portions. Often coils have microbial contamination, you should assume your AC coil has microbial contamination, and have it cleaned using a pressurized wet cleaning process…no exceptions!

Have The HVAC Cleaning Company Clean Your Air Handling Unit: This means they should remove and clean the motor/blower, clean the burners as well as remove the heat exchanger and clean it. While they are conducting all the previous they should clean both the inside and outside of your furnace compartment just like monster Vac does. Always require visual proof that the job has been properly done.

Make Certain The Company You Choose Has Sufficient Suction: Without sufficient suction power a HVAC cleaning company can’t get your system clean. Require written proof that the company you select has at least 4500 cubic feet per minute suction. If they don’t they are not cleaning to NADCA standards.. You are also running the risk of cross contaminating your system if there is not enough suction. Monster Vac uses a truck mounted system that idles at 21,000 cubic feet per minute.

Your HVAC Cleaning Company Should Have Multiple Tools & Methodologies: Experienced HVAC cleaning companies know that 1 fact is true: It is unrealistic to expect that 1 tool or 1 methodology will work for all environments they encounter. A quality HVAC company will have all the tools and methodologies available to them. Any company you use should have direct contact methods, central collection or negative air methods, hand agitation, mechanical agitation and compressed air. They should always use clean sanitized equipment so they can get your system clean, not just less filthy. Monster Vac utilizes all methodologies and tools as needed.

You Should Get Visual Proof That Your System Has Been Cleaned: Your cleaning company should offer you visual proof that your system has been cleaned-using visual, video or photo proof before you write them a check. Some companies offer to show you how much debris came out of the system. Some companies send you a photo in the mail of part of the system that’s easy to get to. Don’t be fooled. The photo could be of someone else’s system and your system could still be dirty. Demand that you be shown visual proof for at least 14 critical areas that do not usually get cleaned:

2 supply branches — Full Length
2 Return Branches — Full Length
Supply Trunk Line — Full Length
Return Trunk Line — Full Length
Motor /Blower Assembly
Blower Compartment
AC Evaporator Coils — Top
AC Evaporator Coils — Bottom
Heat Exchanger — Top
Heat Exchanger — Bottom
Condensate Drain Pan and Burner Compartment

Without definite proof that these areas are CLEAN, you could be left with a system that is just . . . LESS FILTHY! (Back to top of page)
