What should I do if my whole house humidifier stops working?
A whole-house humidifier that stops working is usually caused by a power, water supply, or control setting issue, so check those basics first before scheduling service. The most common cause is a clogged water panel or an incorrectly set humidistat, and many systems only run when the furnace is heating. On bypass models, a stuck damper can quietly stop output even when everything else looks fine. If you need a pro,…
Where should HVAC UV light be installed near the evaporator coil?
An HVAC UV light for coil treatment should be mounted inside the supply plenum with a clear line of sight so the lamp shines directly on the evaporator coil and the drain pan. This placement targets the damp coil surface where microbial growth often starts and helps keep the coil clean between maintenance visits. For homes we service, we install in-duct UV lamps as part of indoor air quality solutions across the…
Can an air purifier be repaired if the UV bulb stops working?
Yes—most in-duct UV air purifiers can be repaired by replacing the failed UV bulb. The usual cause is a spent lamp because UV intensity drops well before a visible burn‑out.

A technician will size the lamp to your air handler and airflow…

How much does professional air duct cleaning service cost?
Professional air duct cleaning cost depends on your home and duct condition. We inspect first and give an upfront price before work begins. Key factors: number of supply/return vents, duct length, access to trunks, debris level, and add-ons like coil cleaning, filter upgrades, or sanitizer. Regular filter changes and a yearly tune-up help extend time between cleanings. We serve Denver, Thornton, and nearby areas. Home Care Club members get priority scheduling and two free filter changes.
