FAQs
What does it mean that your technicians are NATE-certified, and why is that important for my HVAC replacement in McDonald?
NATE (North American Technician Excellence) certification is the most widely recognized credential in the HVAC industry. A NATE-certified technician has passed rigorous, proctored exams covering core HVAC principles and specific equipment specialties such as air conditioning, heat pumps, and gas furnaces. When you hire us for an HVAC unit replacement in McDonald, you can be confident the work will be done to the highest technical standards—ensuring correct sizing, precise refrigerant charging, proper airflow, and full compliance with local building codes. This leads to better system performance, fewer callbacks, and a longer-lasting investment.
How do I know whether I should replace my HVAC system instead of repairing it again?
Age, repair frequency, energy bills, and comfort issues are the main decision factors. If your system is 10–15 years old, needs major repairs (such as a failed compressor or cracked heat exchanger), or has required service more than twice in the past two years, replacement is usually more economical. Rising energy bills, uneven temperatures, excessive noise, or the use of the phased-out R-22 refrigerant are additional red flags. Our NATE-certified techs can perform a detailed assessment and load calculation to confirm whether a new, high-efficiency unit will save you money and improve comfort over the long term.
How long does a typical HVAC unit replacement take in the McDonald area?
Most standard residential change-outs can be completed in a single day. We start by arriving between 8:00–9:00 a.m., safely removing and recycling the old equipment, and installing the new outdoor condenser, indoor air handler or furnace, thermostat, and any required duct transitions. We pressure-test and evacuate the refrigerant lines, charge the system to factory specs, calibrate airflow, and perform a full operations check. More complex projects—such as adding zoning, replacing extensive ductwork, or upgrading to a dual-fuel setup—may take 1–2 additional days. We give you a detailed schedule up front so you can plan accordingly.
What does an HVAC replacement cost, and do you offer financing for McDonald homeowners?
Costs vary based on system size, efficiency rating (SEER2, HSPF2, AFUE), brand, and any duct or electrical upgrades. In McDonald, a typical 2-3 ton air-conditioner and gas furnace replacement ranges from $7,500 to $12,000 installed. High-efficiency heat pumps or inverter systems can run $10,000–$15,000. We partner with several lenders to provide low-interest financing and 0% promotional plans, so you can spread payments over 12–120 months. We also help you capture manufacturer rebates, utility incentives from Duquesne Light/FirstEnergy, and federal tax credits under the Inflation Reduction Act.
How much can I expect to save on energy bills with a new high-efficiency HVAC unit?
If your current system is 10–15 years old with a SEER of 10 and 80% AFUE, upgrading to a 16–18 SEER air conditioner and 96% AFUE furnace can cut cooling costs by 25–40% and heating costs by 15–20%. Heat pumps rated 18–20 SEER2 and 9.0–10.5 HSPF2 can provide even greater savings, especially during McDonald’s mild spring and fall seasons when they run in efficient heat-pump heating mode. Over the 15-year life of a system, these savings typically offset a large share of the upfront investment while reducing your carbon footprint.
What warranties and post-installation support do you provide?
All systems we install carry a 10-year parts warranty and a 1-year labor warranty as standard. Because our technicians are NATE-certified and we follow strict commissioning protocols, most manufacturers allow us to register your equipment for extended 10- or 12-year compressor and heat exchanger coverage at no extra charge. We also include a complimentary first-year maintenance visit to inspect, clean, and fine-tune the system. After that, you can enroll in our Comfort Club, which provides twice-annual tune-ups, priority scheduling, and 15% off repairs—ensuring your new HVAC unit in McDonald stays efficient and reliable for years to come.
