FAQs
Why is a precise load calculation necessary before replacing my HVAC unit?
A proper load calculation ensures the new system is neither too large nor too small for your home. By analyzing square footage, insulation levels, window orientation, local McDonald climate data, and occupancy patterns, we determine the exact heating and cooling capacity you need. This prevents short-cycling, reduces energy waste, extends equipment life, and keeps every room comfortable year-round.
What standards or methods do you use to perform load calculations in McDonald?
We follow ACCA Manual J for residential heat-gain/heat-loss calculations, Manual S for equipment selection, and Manual D for duct design. Our technicians measure your home on-site, enter the data into ACCA-approved software, and factor in McDonald’s specific design temperatures and humidity levels to generate an accurate sizing report.
How can an incorrect load calculation affect my comfort and energy bills?
An oversized system will reach the thermostat setting too quickly, causing rapid on-off cycling that wastes energy, creates temperature swings, and offers poor humidity control. An undersized system runs constantly but still fails to reach set points, leading to high utility costs and premature wear. Either mistake can shorten equipment life and compromise indoor air quality.
How long does the load calculation and replacement process usually take?
The on-site assessment typically takes 60–90 minutes for an average McDonald home. We then complete the software analysis and prepare a proposal within 24 hours. Once you approve the estimate, most standard HVAC replacements are finished in a single day, including removal of the old unit, installation, testing, and homeowner orientation.
Can a properly sized new system qualify me for energy rebates in McDonald?
Yes. Utilities and manufacturers often require proof of ACCA-compliant sizing to issue rebates or low-interest financing. By documenting the Manual J and Manual S calculations, we help you meet eligibility criteria for programs such as Energy Star equipment rebates, local power company incentives, or federal tax credits.
Will I need to upgrade my ductwork when replacing the HVAC unit?
Not always, but the load calculation may reveal airflow restrictions or mismatched duct sizing. If ducts are undersized, leaky, or poorly insulated, we’ll recommend sealing, resizing, or insulating them to ensure the new system delivers its rated efficiency and comfort. Addressing duct issues during replacement is often the most cost-effective time to do so.
