The Importance of AC Filter Replacement for a Cool and Healthy Home

This audit provides a comprehensive assessment of a residential home’s heating and air conditioning requirements, focusing on efficiency, appropriate system sizing, and overall comfort. 1. Home Inspection Overview A. Square Footage Assessmen t • Room Measurements : Each room's dimensions are recorded to determine total square footage. • Ductwork Requirements : Assessment of existing ductwork size to ensure compatibility with system requirements. B. Ductwork and Insulation Inspection • Ductwork Size : Evaluation of current duct sizes for optimal airflow distribution. • Insulation Inspection : Verification of insulation quality (R-value) in walls, attics, and ducts to ensure adequate thermal performance. C. Window Inspection • Window Sizes and Locations : Documentation of all windows, including sizes and orientations. • Thermal Transfer Analysis : Evaluation of insulation in window frames to determine heat transfer efficiency. 2. Electrical Supply Evaluation • Current Electrical Capacity: Inspection of existing wiring (cables and gauge) to ensure it can support the new heating and cooling system requirements. • Surge Protection Needs : Assessment of whether an electrical surge protector is necessary based on the new equipment. 3. Ductwork and Register Analysis • Ductwork Condition : Verification of duct integrity and size, ensuring proper airflow and minimal energy loss. • Register Placement : Review of current register locations for optimal air distribution throughout the home. 4. Customer Consultation • System Preferences : Full consultation to discuss preferences and needs, including: o Desired airflow improvements o Air quality enhancement options (e.g., air scrubbers, UV lights) o Energy efficiency goals (lower electrical bills, reduced kWh usage) o Heat source preferences (all-electric heat pumps vs. ultra-low NOx gas/electric systems) o Potential upgrade to a smart Wi-Fi thermostat 5. Additional Recommendations • Air Quality Systems : Discuss options for air purifiers or filtration systems to improve indoor air quality. • System Upgrades : Provide recommendations for system enhancements based on findings from the audit. Conclusion This audit aims to equip homeowners with a detailed understanding of their heating and air conditioning needs, ensuring efficient and effective solutions tailored to their specific preferences and requirements. For further steps, we can schedule the installation of recommended systems or enhancements based on the findings of this audit.

At Caledonian Mechanical Inc., we take pride in delivering comprehensive planned HVAC maintenance to ensure that commercial heating systems operate at their peak efficiency. A properly maintained heating system not only ensures optimal comfort for your building but also reduces energy consumption, lowers repair costs, and extends equipment lifespan. Our Planned Maintenance (PM) Program includes two heating and two cooling checks annually, ensuring year-round system reliability. Each service visit involves detailed inspections, testing, cleaning, and documentation to identify and prevent potential issues before they lead to costly breakdowns. After each maintenance visit, our customers receive a digital checklist report with photos of any discovered issues, along with a clear breakdown of recommended repairs or solutions. Step-by-Step Breakdown of Our Heating Planned Maintenance Each heating maintenance visit includes critical tests, inspections, and adjustments to keep your system running efficiently. 1. Heat Exchanger & Combustion Analysis Measure and record the temperature rise across the heat exchanger to confirm proper heat transfer. Conduct a combustion analysis to ensure there are no cracks or corrosion in the heat exchanger, preventing potential carbon monoxide leaks. 2. Static Pressure & Airflow Testing Measure and record static pressure differentials to verify the system is operating within manufacturer specifications. Ensure proper airflow distribution to maximize efficiency and prevent overheating. 3. Gas System Testing & Calibration Inspect, test, and record: • Burners and flame sensor for cleanliness and function. • Gas valve manifold pressure to confirm proper gas flow. • Inlet gas pressure from the building supply to prevent excessive fuel consumption or underheating. Adjust gas flow to maintain proper combustion efficiency. 4. Blower Motor & Fan Belt Inspection Inspect and record blower motor voltage and current readings to detect early signs of failure. Check and replace fan belts, ensuring correct tension and torque calibration. 5. Economizer Testing & Fresh Air Intake Inspection Test fresh air economizer functionality, verifying operation from 10% to 100% fresh air demand. Inspect and clean economizer steel filters to maintain indoor air quality and efficiency. 6. Electrical Safety & Component Testing Inspect electrical connections for overheating, dark marks, or loose terminals. Measure voltage and current readings for all major electrical components: • Blower motor • Inducer motor • Other components involved in the heating cycle Test and record run and start capacitors to ensure proper electrical efficiency. 7. Ignition System & Safety Controls Testing Ohm out hot surface ignition or spark ignition to confirm proper function. Test pressure switches and high-temperature safety switches to ensure they properly shut down the unit if overheating occurs. 8. Air Filter Replacement & Ductwork Inspection Replace air filters and clean fresh air economizer filters. Conduct a ductwork inspection to check for leaks, poor insulation, or blockages affecting efficiency. 9. Thermostat & Sensor Calibration Verify proper thermostat and sensor calibration for accurate temperature control. Test the functionality of all climate control sensors. 10. Unit Labeling & Documentation for Future Service Label each rooftop unit (RTU) with its location and unit number for easy identification in future maintenance or repairs. Provide a detailed digital report to the customer, including: • Inspection findings • Photos of any issues • Breakdown of recommended repairs or upgrades • Efficiency improvement recommendations Why Regular Heating Maintenance Matters Lower Energy Costs – A properly tuned system minimizes excessive gas and electricity consumption. Prolonged Equipment Lifespan – Preventing wear and tear extends the life of your RTUs. Fewer Emergency Repairs – Early issue detection reduces the risk of expensive no-heat service calls. Improved Safety – Prevents risks such as gas leaks, carbon monoxide exposure, and overheating. Optimized Comfort – Ensures consistent and reliable heating throughout your facility. By investing in a planned maintenance program, you significantly reduce the risk of unexpected system failures, keeping your business operations running smoothly while maintaining a comfortable indoor environment.
