FAQs
What qualifies an air-conditioning unit as “high-efficiency,” and why does that matter in McDonald’s climate?
A high-efficiency air conditioner is generally defined as one that carries a Seasonal Energy Efficiency Ratio (SEER2) rating of 15.2 or higher. These systems use advanced compressors, variable-speed blower motors, and larger, better-designed coils to move more heat with less electricity. McDonald experiences hot, humid summers and cool, damp shoulder seasons, so a unit that runs longer at a lower speed maintains steadier temperatures and de-humidifies better than a standard single-stage system. The result is lower electric bills, fewer temperature swings, quieter operation, and reduced greenhouse-gas emissions.
How much can I expect to save on energy bills by upgrading to a high-efficiency system?
Savings vary by home size, insulation level, and current equipment, but most McDonald homeowners see 20–40 % lower cooling costs after replacing a 10–12 SEER unit with a 16–18 SEER2 model. If your existing system is more than 12–15 years old, the payback period for the upgrade is typically 3–6 years when you factor in lower utility bills, available rebates, and reduced repair expenses. We provide a free in-home load calculation and cost-of-ownership analysis so you’ll know your projected savings before committing.
Are rebates or tax incentives available in McDonald for high-efficiency air-conditioning installations?
Yes. Through the Inflation Reduction Act (IRA) and Pennsylvania’s ACT 129 utility programs, eligible homeowners can receive federal tax credits up to 30 % of the project cost (capped at $2,000 for qualifying heat pumps) and utility rebates that typically range from $150 to $500 for high-SEER2 central air units. Low- to moderate-income households may qualify for even larger point-of-sale discounts under the forthcoming HOMES and HEEHR programs. Our staff keeps up with current incentives, completes the paperwork, and deducts the rebate amount from your invoice whenever possible.
How does a high-efficiency air conditioner improve comfort compared with a standard system?
High-efficiency units use variable-speed or two-stage compressors that adjust output in tiny increments instead of turning on at full blast and then shutting off. This longer, slower run time keeps indoor temperatures within ±1 °F of the thermostat setting, removes more humidity, and reduces hot and cold spots—especially in multi-story homes common around McDonald. Because the system ramps up gradually, it is also noticeably quieter, both indoors at the air handler and outdoors at the condenser.
What maintenance does a high-efficiency air-conditioning system require, and can your company handle it?
Although today’s units are engineered for reliability, they do contain more sophisticated electronics and variable-speed motors that should be inspected annually. Our Precision Tune-Up includes coil cleaning, refrigerant charge verification, static-pressure testing, firmware updates for communicating thermostats, and verification of airflow and drain function. Regular maintenance keeps the manufacturer warranty valid, maximizes efficiency, and can add 3–5 years to system life. We offer cost-effective maintenance agreements that include priority scheduling and discounts on any needed repairs.
How long will installation take, and will my existing ductwork need to be modified?
Most straight AC change-outs in McDonald are completed in a single day. If we’re installing a high-efficiency variable-speed system, we perform a Manual J load calculation and inspect your ducts for leaks, sizing, and insulation. Roughly 30 % of older homes require minor duct sealing or the addition of return air to reach the system’s published efficiency and meet code. We discuss any needed modifications up front, and our in-house sheet-metal team can complete the work during the same appointment so you’re never left without cooling overnight.
