FAQs
What does it mean to be NATE–certified, and why should I insist on NATE–certified technicians for my HVAC replacement?
NATE (North American Technician Excellence) certification is the industry’s most recognized credential for HVAC professionals. To earn it, technicians must pass rigorous exams that prove their knowledge of heating, cooling, ventilation, and refrigeration systems. When you hire our NATE–certified team in Guild, you’re assured that your new system will be sized correctly, installed to manufacturer specifications, and optimized for peak performance. Proper installation not only maximizes comfort and efficiency but also protects your new-equipment warranty and helps prevent costly breakdowns.
How do I know if it’s time to replace rather than repair my current HVAC unit?
Consider replacement when your system is 10–15 years old, needs frequent or expensive repairs, or struggles to keep your home comfortable. Rising energy bills, uneven temperatures, loud operation, and R-22 (Freon) refrigerant usage are additional red flags. Our technicians can perform a cost-benefit analysis that compares the expense of repair against the long-term savings and reliability benefits of installing a new, high-efficiency unit.
What types of heating and cooling systems can your NATE–certified technicians replace in Guild?
We replace a full range of residential and light-commercial equipment, including gas and electric furnaces, central air conditioners, heat pumps (air-source and ductless mini-split), dual-fuel hybrid systems, packaged rooftop units, and high-efficiency boilers. Whatever brand you currently have, we can recommend an upgraded model that meets local climate needs, building codes, and manufacturer rebate requirements.
How long does an HVAC unit replacement take, and will I be without heating or cooling during the process?
Most standard furnace or air-conditioner replacements are completed in a single day. Complex jobs—such as full system change-outs, duct modifications, or multi-zone heat pump installations—may take 1–3 days. We schedule the work so downtime is minimized; if extreme weather is expected, we can provide temporary space heaters or portable AC units. Before we leave, we test-run the new equipment, program thermostats, and clean the work area thoroughly.
What kind of energy efficiency improvements and cost savings can I expect with a new HVAC system?
New units today are up to 30–50 % more efficient than systems installed just a decade ago. A high-efficiency furnace (AFUE 95 %+), a 16–20 SEER2 air conditioner, or a variable-speed heat pump can lower annual utility bills by hundreds of dollars. You’ll also enjoy better humidity control, quieter operation, and improved indoor air quality. Our team provides a detailed load calculation and savings projection so you can see the payback period before you commit.
Do you offer financing, warranties, and maintenance plans with a replacement installed by your NATE–certified team?
Yes. We partner with leading lenders to provide low-interest and no-interest promotional financing options, often with same-day credit decisions. All systems come with a manufacturer parts warranty (typically 10 years) and our own labor warranty, which can be extended for extra peace of mind. After installation, we offer cost-effective preventative maintenance agreements that include semi-annual tune-ups, priority scheduling, and discounts on any future repairs.
