Kennesaw HVAC Replacement: Frequently Asked Questions

When is it smarter to replace instead of repair?
Consider age (10–15+ years), frequent breakdowns, high utility bills, or costly major components. Many use the “$5,000 rule” (age × repair cost). If it exceeds 5,000, replacement often makes more sense.
How do installs work in townhomes/condos near KSU?
We coordinate access, parking, and any crane needs for rooftop/awkward placements, comply with HOA rules, and provide COI when required. We keep common areas clean and minimize noise during permitted work hours.
Will my existing line set and electrical work with the new system?
We inspect gauge/length, pressure‑test and clean (or replace) the line set as needed, verify breaker size/wire gauge, and ensure the disconnect/pad meet code. For refrigerant transitions, we follow manufacturer and code requirements.
How quiet are newer systems—and can placement reduce noise?
Variable‑speed condensers and indoor blowers run quieter than older single‑stage units. Proper mounting, clearances, and anti‑vibration pads reduce sound further. We’ll review placement options with you.
What maintenance is recommended after replacement?
Replace filters regularly, keep the outdoor coil clear, and schedule bi‑annual tune‑ups to protect warranties and performance. We include commissioning data and maintenance tips at install. Questions? Call +1 (470) 555‑0123.
