Our HVAC Cleaning Services in East Palo Alto
Evaporator Coil Cleaning
The evaporator coil in your air handler is where moisture collects and where mold starts. In East Palo Alto’s humid bay environment, this happens faster and more aggressively than in drier Peninsula cities. We remove the coil assembly, clean it with foaming agents safe for your equipment, and treat it with an antimicrobial coating that inhibits regrowth through the damp season. A typical evaporator coil cleaning in East Palo Alto runs $180-$340.
Blower Cleaning
Your blower motor and wheel push conditioned air through every room. When they’re coated with dust and microbial growth, airflow drops and your system works harder for less comfort. In EPA’s older homes, we often find blowers caked with debris that passed through decades-old filters or entered through poorly sealed return plenums. We disassemble, clean, and balance the blower assembly. Most blower cleanings in East Palo Alto are $150-$280.
Condenser Cleaning
The outdoor condenser unit faces salt-laden bay winds and pollen from the nearby estuary wetlands. Coils clogged with outdoor debris can’t reject heat efficiently, raising your electric bill and shortening compressor life. We clean coils, straighten fins, and check refrigerant levels. Condenser cleaning in East Palo Alto typically costs $120-$220 as a standalone service, or it’s bundled into a full system clean.
Air Handler Cleaning
The air handler is the heart of your HVAC system, and in East Palo Alto’s legacy homes, it’s often a new unit bolted to old ductwork. We clean the entire cabinet, drain pan, and associated components, then inspect the connection points where your modern handler meets original galvanized trunk lines. This is where we frequently find the worst moisture damage and biological growth. Air handler cleaning in East Palo Alto runs $200-$380 depending on accessibility and condition.
Coil Treatment
After cleaning, we apply an EPA-registered antimicrobial treatment to coils and drain pans. In East Palo Alto’s persistent humidity, this step isn’t optional - it’s what keeps mold from returning within months. Our coil treatment uses products from Guardsman formulated for marine-climate HVAC systems. Treatment adds $80-$140 to a coil cleaning service.
Heat Exchanger Cleaning
For homes with gas furnaces, the heat exchanger must be clean and intact for safe, efficient operation. We inspect with cameras and clean as needed. This service is $160-$300 in the East Palo Alto market.

Common HVAC Cleaning Problems We See in East Palo Alto Homes
- Decades of uncleaned sheet-metal ducts harbor mold and bacteria. The bay moisture that seeps into crawl spaces and attics condenses on cold metal duct surfaces, creating ideal conditions for microbial growth that bypasses even new HVAC filters.
- Unpermitted HVAC swaps left original duct runs with poorly sealed joints. When homeowners or landlords upgraded equipment without pulling permits, they often spliced flex duct into old galvanized trunks with tape or inadequate clamps. Air leaks at these points draw humid crawl-space air into the system, accelerating corrosion and contamination.
- Renovated homes have retrofitted ductwork mixing old and new materials. The connection points between rigid galvanized trunk lines and modern flex duct trap debris and moisture, creating concentrated contamination zones that standard cleaning may miss without camera verification.
- Salt-laden bay air corrodes outdoor condenser coils. East Palo Alto’s onshore winds carry marine aerosols that coat condenser fins with salt residue, reducing heat transfer and pitting aluminum surfaces over time.

FAQs - HVAC Cleaning in East Palo Alto
East Palo Alto’s bay-level elevation and persistent marine humidity create condensation inside metal ductwork that drier hillside neighborhoods simply don’t experience. This moisture sustains mold and bacterial growth year-round, not just during rainy season, making professional cleaning with antimicrobial treatment a genuine air-quality remediation need rather than simple dust removal. Call (844) 685-6342 - we’ll inspect your system with cameras and show you exactly what’s growing in there.
Most 1950s galvanized ductwork in East Palo Alto can be professionally cleaned if it’s structurally intact, though we frequently find systems where unpermitted upgrades have left original trunk lines poorly connected to modern equipment. We camera-inspect every foot before recommending replacement; often, thorough cleaning plus sealing at connection points restores function without the cost of full duct replacement. In a 1950s tract home on Bay Road, we found a 1955 galvanized trunk line still connected to a modern air handler, packed with rodent debris and black mold from decades of unseen moisture. Our Rotobrush system removed 12 pounds of debris and we applied an antimicrobial coil treatment to restore indoor air quality. Call for a free inspection - estimates are free.
Yes, especially in East Palo Alto where unpermitted upgrades often leave original duct runs in place. Your new air handler is likely recirculating decades of accumulated debris and biological growth through ductwork that was never cleaned. We recommend cleaning the full duct network whenever new equipment is connected to legacy infrastructure. The $380-$650 for full system cleaning protects your investment in new equipment and your family’s air quality. Call (844) 685-6342 to schedule.
We use Rotobrush mechanical brushing systems for debris removal, Nikro HEPA vacuums for containment, and Guardsman antimicrobial treatments formulated specifically for high-humidity marine climates. For severe mold remediation, we deploy Abatement Technologies negative-air machines to protect your home during cleaning. These are the same brands specified by commercial HVAC contractors for demanding environments. Call for details on our process - estimates are free.
Severe mold contamination can add $100-$250 to a standard cleaning because it requires extended contact time with antimicrobial agents and more thorough HEPA vacuuming. However, our base pricing is consistent across the Peninsula - we don’t surcharge for East Palo Alto specifically. The camera inspection lets us quote accurately before work begins, so you know the full cost upfront. Call (844) 685-6342 for your exact quote - estimates are free.
