Freezing Mechanical installs best-in-class UV lights from Reme Halo.

In Miami, Florida, the cost of a UV light installation varies between $350 and $700+, with most homeowners spending an average of $450.

UV lights are great for eliminating household odors, killing bacteria and viruses, and other benefits. They’re also perfect for combatting high humidity in southeast Florida, where HVAC systems are prone to mold and mildew.

So, if you want to breathe cleaner, healthier air, we definitely recommend installing a UV light in your Miami home!

To help you understand what goes into the cost of a UV light installation, let’s review key cost factors:

The Type of UV Light You Install

There are two different types of UV light cleaners. One purifies the air inside your air ducts, and another cleans your AC’s evaporator coils. Depending on your needs and budget, you can install one or the other, or both. Just know that if you install both types, your costs will increase.

Air Sterilizing

UV light air sterilizers tend to be more expensive than coil sterilizers.Why? Because they’re more powerful. They need to have enough wattage to clean all of the air flowing through your ductwork, and that’s no small feat!

Placed inside your AC’s return air ducts, the UV light bulbs will sanitize the air getting pulled into your AC before it’s cooled. That way, your AC is cooling clean air, and you don’t end up with dirty air passing over your evaporator coils. Since dirty evaporator coils can lead to mold growth, this is a win-win!

The downside of air sterilizing UV lights is that they must be monitored closely. If you don’t swap them out when a replacement is due, your air quality will be greatly reduced. Moreover, they can be difficult to maintain, since your HVAC technician will need to access your air ducts, which could be difficult to reach.

Coil Sterilizer

Coil sterilizers are one of the most common UV lights installed in Miami homes. They are less expensive than air sterilizing versions and incredibly effective at zapping any bacteria or viruses (like toxic mold spores) that pass over your AC’s coils.

High humidity is a big problem here in Southeast Florida. Your AC will naturally reduce some humidity in the air, but not all– and that’s when mold becomes a problem. Over time, your AC’s evaporator coils may develop mold spores, so when air passes over the coils, it will then carry that mold throughout your home.

To remedy this problem, an HVAC technician can install a UV light directly on top of your AC’s evaporator coils. This way, any airborne bacteria gets zapped before it has a chance to spread.

Coil sterilizing UV lights come in single or dual lamp versions and must be replaced periodically. However, they tend to be less expensive (and less timely) to replace, which makes them a more economical choice for homeowners.

Modifications to Your HVAC System

UV lights are relatively straightforward to install, but if you need any modifications to your HVAC system, your costs will go up.

For example, if your air ducts have holes or tears, it’s not worth installing a UV light because all the sanitized air will escape to unconditioned spaces. You’ll need to pay for your air ducts to be repaired or replaced in addition to your UV light installation.

Similarly, if your AC system is severely damaged or outdated, you may need a brand new replacement. Older ACs have reduced capacity, so they can’t dehumidify as much air. This means your UV lights will have to work much harder to clean your air, which isn’t a cost-effective solution. Rather than installing UV lights, you may benefit more from an upgraded cooling system.

The Contractor You Hire

Lastly, the contractor you hire to install your UV lights will greatly impact your overall costs.

Some homeowners opt for a DIY installation to save a bit of money, but we don’t recommend it. Your HVAC system is a complex and expensive investment that deserves to be protected by trained professionals. It can take Freezing Mechanical’s NATE-certified pros up to four hours to install UV lights correctly, so if you don’t know what you’re doing, it can be both time-consuming and potentially dangerous.

  • Proof of licensing and insurance

  • More than 10 years of experience
