UV light installation in London, Ontario
Target what your filter can’t
Donaldson Home Services installs UV lights inside the furnaces and air conditioners of homes in London and surrounding communities. A UV light shines ultraviolet light on the indoor cooling coil or into the ductwork to help limit mould and bacteria growing on those surfaces, something your filter can’t do.
Looking for more than filtration?
Filters are designed to capture particles as air moves through your furnace. UV light systems work differently, using ultraviolet light within the system as an additional form of air treatment.
A UV light system may be worth considering if:
Not every indoor air concern can be addressed with UV light. Donaldson can assess your HVAC equipment and help determine whether UV technology (or another indoor air quality solution) is appropriate for your home.

UV light, professionally installed
Where a UV light is installed, which equipment it’s paired with, and the type of system used all matter. Donaldson will assess your existing HVAC equipment before recommending and installing a UV solution.
We’ll help you understand what the system is designed to do, what it isn’t, and whether it makes sense for your home. UV light is one of our indoor air quality services and works alongside whole-home air purifiers and HRV and ERV ventilation, for homes in London and surrounding communities.
What to expect
Adding UV technology to your HVAC system starts with making sure the equipment and installation are appropriate for your existing setup.

Step two
Home assessment
We’ll inspect your existing heating and air conditioning equipment, filtration setup and available installation locations to determine which UV options are compatible with your system.

Another layer of air treatment

What your neighbours are saying about us
What does a UV light do in your HVAC system?
An HVAC UV light uses UV-C light to act on mould, bacteria and other microorganisms on the surfaces and in the air it reaches, most often the indoor coil. It doesn’t trap dust or replace your filter; it works alongside it.
UV light & HVAC equipment
Depending on the product and placement, UV equipment may be installed near components such as the indoor coil or within ductwork. The appropriate location depends on what the particular UV system is designed to do.
UV light & air filtration
UV systems and HVAC filters perform different jobs. A filter captures particles moving through the system, while UV technology uses ultraviolet exposure. That’s why UV should be considered a complement to appropriate filtration, not a substitute for it.
The system matters
UV performance depends on factors including the equipment used, installation location, intensity and exposure. Donaldson can recommend a product based on the intended application rather than assuming every UV system performs the same way.

UV light FAQs
Have more questions? We’ve got the answers.
An HVAC UV light shines ultraviolet (UV-C) light on the cooling coil or into the air stream to limit mould and bacteria growth. Its specific purpose and effectiveness depend on the UV equipment, placement and application. Not sure it suits your system? Ask our team.
Not necessarily. “Air purifier” can refer to several types of air-treatment technology. UV systems specifically use ultraviolet light, while other air purifiers may rely on filtration or other technologies. Donaldson can help you understand which option fits your indoor air concerns, or you can compare whole-home air purifiers.
No. Your HVAC filter captures particles and helps protect your heating and air conditioning equipment. A UV light performs a different function and is generally used alongside appropriate HVAC filtration, so regular filter changes still matter. They’re part of routine furnace maintenance.
HVAC UV lights are installed within the heating and air conditioning system. Depending on the product and intended application, the equipment may be positioned near specific HVAC components or within the duct system. Proper placement is important for the system to operate as designed. To check your system’s options, book an assessment.
Yes. UV lamps lose output over time and typically require periodic replacement according to the equipment manufacturer’s recommendations. Other maintenance depends on the system installed, and Donaldson explains the ongoing care and lamp replacement your system needs before we leave. Questions about an existing UV system? Contact our team.
UV systems can be added to many existing HVAC systems, provided there is appropriate equipment compatibility and a suitable installation location. Donaldson can inspect your system and determine which options are appropriate. It’s often added while upgrading other equipment; see our indoor air quality services.
The cost depends on the UV system selected, your existing HVAC equipment and the requirements of the installation. Donaldson assesses your system first and gives you clear recommendations and pricing for the UV solution appropriate for your home before moving forward. Request a quote.
