YES. Annual cleaning is required to keep the unit running; it's as important as changing the oil in your car. If a yearly cleaning is skipped, the heat pump has to work harder and harder to meet the heating and cooling needs of the home or business. This will eventually break down the unit and might mean costly and inconvenient service visits, repairs, or even replacement.
On the day of our visit, we carefully dismantle the interior unit, then use a pressure washer and a non-toxic/non-acidic cleaning solution along with a bib-kit to remove the material that builds upon the heat exchanger and the fan wheel. The bib kit funnels all of the water & debris into a bucket, so you don't need to worry about water spray in your home. We then dismantle and clean the coil, fan, drain, and cabinet of the exterior unit using the same tools. We check both the interior and exterior units for potential service issues, vacuum the condensate pipes, and provide a courtesy cleaning of the exterior of every unit as we reassemble. We clean or wash the filters and then replace batteries and filter inserts.
We test the system before leaving and communicate all we discovered with you. Our techs make notes in our system for future cleanings. If there's an issue, we will report it to you and, if needed, a service provider, preventing downtime and costly visits down the road.
We don't recommend it. You should never attempt a DIY cleaning without a thorough understanding of the system and how it works or the specialty tools and techniques that we use. If the power isn't disconnected correctly, you might fry your system. It's easy to damage the coils, and even one improper cleaning can leave them bent, rusted, and requiring costly repairs, or not clean at all with dirt, mold, and other material compacted into the unit.
YES. Over time the physical weight of built-up debris and the limited air movement across the coil leads to a dramatic decrease in efficiency and effectiveness. There will be an immediate 10-25% increase in productivity after the cleaning. It often pays for itself in energy savings and noticeably increases effectiveness and air quality.
YES. Ductless mini-split heat pumps cycle air across a heat exchange coil. Under normal usage, dust, dirt, hair, mold, pollen, grease, etc., get deposited on the fan and the coil. When cleaned annually, your heat pump will clean and purify the air. When left uncleaned, your heat pump will produce allergens and contaminate the air.
We do not remove the fan wheel. After many years, we have developed our technique with a specific focus on heat pump cleaning. Our process of cleaning the fan wheel in place may take longer if the system is filthy, but we believe that unnecessary, repeated removal of the fan wheel can cause damage. We'd rather slowly and carefully clean your system, ensuring that it stays operating at 100% for as long as possible.
