Common Air Conditioning Issues in Los Altos Hills and How We Diagnose Them

• Uneven cooling across multi-level homes: Often caused by zoning problems, duct leaks, or inadequate airflow. We measure static pressure and inspect duct runs in crawlspaces and attics common to local homes.
• System short-cycling or poor efficiency: Caused by incorrect refrigerant charge, failing compressors, or improper system sizing. Diagnostic testing pinpoints the cause and recommends repair or replacement.
• Poor indoor air quality during wildfire season: Fine particulates and smoke odors can infiltrate homes. We test ventilation paths and propose filtration or whole-home purification solutions.
• Noisy operation and increased utility bills: Typically related to worn motors, loose components, or failing bearings. A safety and performance check identifies needed repairs.
• Refrigerant leaks or odors: We perform leak detection, pressure testing, and safe refrigerant handling in compliance with EPA requirements.

Our Diagnostic and Repair Process

1. Initial assessment and history review to understand symptoms and prior service.
2. Visual inspection of outdoor unit, indoor coil, ductwork, electrical connections, and thermostat.
3. Performance testing: refrigerant pressures, temperature split, airflow measurements, and electrical load checks.
4. Written diagnosis and prioritized repair recommendations, including parts, labor, and timeline.
5. Repair work with manufacturer-recommended parts, system testing after repairs, and a documented service report.
6. Follow-up checks on warranty items and system performance as needed.

Installation and System Upgrades for Los Altos Hills Homes

Los Altos Hills homes vary from modern high-efficiency builds to older estates with complex duct systems. Correct installation begins with a Manual J load calculation to size equipment properly and a Manual D plan if ductwork changes are required. We evaluate:

• Duct sealing and insulation for hilly, attic-exposed runs.
• Zoned systems or ductless options for additions and outbuildings.
• High-efficiency heat pumps to improve year-round performance and reduce energy bills.
• Smart thermostats and zoning controls for precise comfort and energy management.Installations include permit coordination and system commissioning to meet local building codes and efficiency standards.

Preventive Maintenance and Service Agreements

Regular maintenance reduces breakdowns, restores efficiency, and preserves warranties. Typical tune-ups include:

• Cleaning evaporator and condenser coils
• Checking refrigerant levels and leaks
• Verifying electrical connections and safety controls
• Lubricating motors and checking belts
• Testing thermostat accuracy and calibrating controls
• Recording all system settings and performance dataService agreements commonly provide two seasonal inspections, priority scheduling during peak heat, discounted diagnostics and repairs, and a permanent service history that helps with warranty claims and resale value.

Indoor Air Quality Add-Ons for Los Altos Hills

Given local wildfire smoke and seasonal pollen, IAQ upgrades are often essential:

• High-MERV whole-home filters or HEPA-compatible systems to capture fine particulates
• UV germicidal lights to reduce microbial growth on coils
• Energy recovery ventilators (ERVs) to maintain fresh air while controlling humidity
• Dehumidification solutions for basements or living areas sensitive to moistureEach option is sized to your system and home layout to avoid airflow restriction or pressure imbalance.

Emergency Service and Rapid Response

When your AC fails during a heat wave, response speed matters. Emergency protocols include remote triage over the phone, prioritized dispatch, temporary cooling solutions where safe, and same-day parts retrieval when feasible. Repairs are performed with safety checks and documented follow-up to prevent repeat failures.

Technicians, Certifications, and Warranty Policies

Our technicians hold industry-standard certifications such as NATE and EPA Section 608 refrigerant handling credentials and complete manufacturer training for major brands. They are background-checked, insured, and receive ongoing technical training to stay current with refrigerants, efficiency standards, and smart controls.

Warranty policies commonly include:

• Manufacturer parts and compressor warranties that vary by equipment
• Labor or workmanship warranties offered after installation or major repair
• Requirements to maintain routine service (often annual) to keep some warranties validWe provide clear warranty documentation, explain registration requirements, and keep service records that support claims.

What to Expect After Service

After any visit you will receive a clear service report outlining diagnostics performed, parts replaced, system settings, and recommended next steps. For installations, expect system commissioning, a walkthrough of controls, and guidance on seasonal maintenance.
