Good to know
Answers before you book.
A few of the questions we hear most. See the full list on our FAQ page.
Yes — we answer calls 24/7, 365 days a year. A live technician (never a machine) will help triage your no-heat or no-cool emergency and get someone dispatched fast.
For most homes, every 90 days — but if you have pets, allergies, or run your system hard, check monthly. A clean filter is the single easiest way to protect your equipment and air quality.
Most residential replacements are completed in a single day. Larger or multi-system homes may take two. We give you an exact timeline before we start.
It depends on your square footage, insulation, windows, and layout — not just a rule of thumb. We perform a proper load calculation so your system is sized right, not just big.
