Air Duct and Dryer Vent Cleaning

Why should I have my air ducts and HVAC system cleaned?

If you are experiencing excess dust, black particles blowing out, mold or fungus on your vent covers or registers, strange odors, ongoing allergies, or health concerns, you must have your entire HVAC system and air ducts cleaned as soon as possible.

How long does the air duct cleaning process take?

A single unit air duct cleaning should take approximately 4-5 hours in total. This includes set up, cleaning and breakdown.

Do I have to leave during the HVAC cleaning process?

No. The products that Pure Air UV Inc. use are registered with the EPA for use of the inside of air conditioning systems and are not harmful to humans or the environment. It is perfectly safe for you and your pets to stay during the HVAC cleaning process.

How often should I get my air ducts and dryer vents cleaned?

Pure Air UV follows the National Air Duct Cleaners Association (NADCA) recommendations. Homeowners should have their air ducts cleaned every 3 to 5 years. Dryer vents should be routinely maintained every year to prevent dryer fires.

General Questions

Why don't you price-match your competitors?

We don’t price-match our competitors because we are not selling a uniform, tangible, easily comparable product. We are selling a service, and many factors contribute to the pricing of our services: the skill and experience of our technicians, the generous wages we pay our staff, the cost of the premium tools and equipment we use, etc. Moreover, any service’s precise nature varies from company to company. A “standard air duct cleaning” for one company may mean something entirely different for another (and probably would have a different name as well). Comparing services among companies is not necessarily comparing apples to apples; a savvy consumer will weigh several factors when comparing companies, only one of which is pricing.

What forms of payment do you accept?

We accept all major credit cards, debit cards, company gift cards, and personal and cashier’s checks.

Why do you charge a rescheduling fee?

The reschedule fee is applicable only when an appointment is canceled or rescheduled with less than 24 hours notice.

Why? Simply put, to protect our technicians. Their routes are scheduled days or weeks in advance. When a customer cancels or reschedules with less than 24 hours notice, it is too late for that appointment to be filled by another customer, and the technician is out of work during that time. Like most of our customers, our technicians are busy earning a living and raising their families, and the rescheduling fee is our way of telling them we respect their time.

Do you perform repairs?

Our expertise regarding HVAC systems is cleaning. Our technicians DO NOT perform repairs or diagnostics of the HVAC system. In cases where our technician observes a more significant problem, we will advise on additional services through a third-party HVAC repair company.

Air Purification Systems

What is the cost of an air purification system?

Residential and Commercial products are installed by our certified technicians. Pricing is determined by the type of product and the difficulty of the installation.

Where can I purchase a replacement lamp (bulb) for my system?

Because UV-C light is dangerous to skin and eyes lamp replacements are provided by service technicians, usually at the same time as routine air system maintenance.

What type of warranty comes with these products?

All of our products come with a lifetime warranty on all parts (except lamps) with the exception of Mini UV which comes with a 5-year warranty. Lamps come with a 1 or 2-year warranty.

Why does UV light kill germs?

UV-C light (the frequency used in germicidal UV lights) kills germs by disrupting their DNA which prevents them from reproducing, effectively killing them. In nature, this frequency of light is filtered out by the Earth’s atmosphere so microbes have no defense against it.

Is UV light safe for children and pets?

When a UV light system is installed in a central air system the germ-killing effect takes place inside the air system and is limited to that area. There is no danger to any living thing in the home except microbes that are carried by the air into the central air system.

Is it OK to look at the UV light?

Never look at the UV light when it is lit. UV-C light can give your eyes a painful “sunburn”. Unplug or disconnect the unit to work on it.

Should the light be on 24 hours a day or only when the blower is on?

These products are intended to be on 24 hours a day. Mold growth doesn’t stop when the blower is off, and cycling the UV light on and off would shorten the life of the UV lamp.

How can we purify the air when the AC or heater isn't on?

Running the air system in “fan” mode will cycle air through the home without turning on the AC or heater. Many programmable thermostats have a setting for this as well.

Can the UV lamp (bulb) be upgraded from a 1 year to a 2-year model?

Yes! Our lamps are interchangeable. When it’s time to replace your 1 year UV lamp you can upgrade to a 2-year model.

My '1 Year' UV light still glows after 2 years - do I need to replace it?

Yes, Over time the UV effectiveness of the lamps decreases even though the lamp may still be putting out visible light. ‘1 Year’ and ‘2 Year’ lamp designations refer to effective UV output not when the lamp will burn out.

Will a UV light system kill mold in the walls?

No. UV-C germicidal irradiation can only kill microbes on surfaces that the light shines on directly (surface kill) or that pass by in the air stream (airborne kill).

Which product is best for the musty smell from our air system in hot weather?

Have your Pure Air UV technician take a look at the air system. If there is mold growing on the cooling coils that could be the source of the musty smell. One of our standard UV light systems like Blue-Tube UV or Fresh-Aire UV Series 1 will kill the mold and eliminate the smell. For odors in general consider our APCO In-Duct Air Purifier. APCO is specifically designed to fight volatile organic compounds (VOCs) which are the source of most household and chemical odors.

Can UV light damage materials inside the air system?

Our UV lamps offer the ideal balance of germicidal effectiveness without damaging UV-sensitive materials inside the air system.

Can you touch the lamps?

Never look directly at, touch, or expose skin close to the UV-C light. Unlike most other manufacturer’s lamps, our lamps can be handled when not lit. This is because they are made using high-quality hard quartz, not the soft quartz found in inexpensive imports (handling soft quartz lamps may cause them to fail).

Is it OK to look at the UV light with sunglasses?

No. Although UV-C light will not pass through plastic or ordinary glass there is still the risk to exposed skin. Always turn off the light or disconnect power to service the system.

Can UV light reduce radon in your home?

No. Radon is a naturally occurring radioactive gas that can seep into your home from the ground below. It is not the product of any volatile organic compound (VOC) or biological contaminant so UV-C light has no effect on it.

Does UV light kill kennel cough germs?

UV-C light will sterilize nearly all microbes with very few exceptions. However, it only affects surfaces that it shines on directly or air that passes through it. Kennel cough is an airborne disease so UV-C would fight its spread through the air system but would have no effect on its spread by dog to dog contact.

Can the UV light system be transferred to a new air handler or furnace?

Yes, most of our systems can be moved to a new air system.

Does the APCO system produce ozone?

No, APCO produces no ozone, in fact, it removes ozone from the air.

How long does it take for the UV light to kill mold?

The germ-killing effect starts immediately with about 90% of surface microbes sterilized within the first few minutes, and about 99.99% sterilized after the first 24 hours.

Will the Ice UV light damage the plastic materials inside our ice machine?

No, Ice UV is designed to emit enough UV-C light to kill mold and germs but not so much that would damage plastic parts. There is, however, a possibility that some harmless discoloration may occur particularly on white plastic surfaces. For that reason, a sheet of protective adhesive vinyl is included with Ice UV.

Should APCO always be installed on the supply duct or is it OK on the return as well?

It is better to install APCO on the supply duct because unfiltered air might deposit dust and other particulates into the carbon cells. However, if the supply duct is not accessible then installation on the return side is acceptable.

Is reflected or distant UV-C light dangerous? What about people with eye problems?

The effect of UV-C light falls off quickly with distance because it is filtered by the atmosphere (air) which is why microorganisms have no defense against it. One should always avoid close direct exposure to skin and eyes but reflected UV-C light at a distance is not at all dangerous.
