Choosing the right HVAC and plumbing company matters. Your home’s comfort systems require experience, precision, and a team that stands behind their work. At Rite Now A/C and Heating, we focus on dependable service, clear communication, and long-term solutions not temporary fixes.
We understand that inviting a service company into your home requires trust. That’s why we approach every project with professionalism, respect for your space, and attention to detail. From the initial inspection to the final walkthrough, our goal is simple: deliver workmanship that meets high standards and exceeds expectations.
For a standard replacement at the same location with compatible ductwork, plan for 4 to 6 hours. More complex installs involving attic equipment, ductwork modifications, or electrical panel upgrades can run a full day. Rite NOW A/C and Heating dispatches same-day in most cases, and we don’t rush the finish. A system that’s installed the first time correctly costs you far less over its lifetime than one that needs a callback.
You need a proper load calculation, not a contractor eyeballing your square footage. The right sizing accounts for your home’s insulation R-values, window area and orientation, ceiling height, ductwork efficiency, and Denton’s specific climate data. Undersized systems run non-stop and fail early. Oversized systems have a short cycle and never properly dehumidify. Rite NOW A/C and Heating performs this assessment on every installation, because wrong-sized is wrong, regardless of brand.
For a complete central AC installation in the Denton area, expect a range of roughly $5,000 to $12,000, depending on system size (tonnage), efficiency rating (SEER2), brand, and whether ductwork work is involved. Rite Now provides a precise, itemized quote before work begins, not a range, a number.
Yes, an adult homeowner or authorized representative should be present for the estimate walkthrough, at the start of the installation, and for the final system test and walkthrough. You don’t need to hover over our technicians, but we’ll need you available to approve the final system operation and ask any questions you’ve saved up.
Almost certainly, if you’re replacing a system that’s more than 8–10 years old. Modern SEER2-rated systems are dramatically more efficient than equipment manufactured a decade ago. In Denton’s extended cooling season, often 5+ months of heavy AC use, the difference in monthly energy cost between an old system and a new high-efficiency unit can be significant. Our technicians can walk you through projected savings at different efficiency tiers during your free estimate.
We come to your home, assess your space, and determine what it genuinely needs. Square footage gets us started. Everything else gets us to the right answer.
We quote a specific number, explain every line, and lock it in. You decide if you want to move forward, no pressure, no countdown clock.
We show up when we say we will. Your old system comes out cleanly, the new one goes in correctly, and we handle every connection, refrigerant, electrical, drainage, and controls.
Full system test before we touch a doorknob to leave. Airflow, charge, drainage, thermostat calibration, all verified. If something's off, it gets fixed on the spot.
Working at RiteNOW isn’t just another job in the trades. It’s joining a team that takes pride in solving real problems for real families across Denton. We’re the people they trust. That responsibility means something here.
We look for people who care about the work, the customer, and the team beside them. If you want steady hours, honest leadership, and a company that backs your growth, you’ll fit right in.
