Most people wait until their furnace dies in January or their AC quits in July before they start looking for help. That's when you're desperate and likely to make a bad call. A few smart moves ahead of time can save you thousands and a lot of misery.
What to Look For
Look for a company that's been in business at least five years. That's long enough to have a real track record and a reputation to protect. They should carry proper licensing and insurance — general liability and workers' comp. Ask for their license number and verify it with your state board. A real shop will have a physical address, not just a P.O. box and a cell phone.
Questions to Ask
Ask how long they've been installing the specific brand they're pitching. Some brands are fine, but only if the installer knows them. Then ask what the warranty covers — parts only, or labor too? Most factory warranties are five to ten years on parts, but labor is usually one year unless you pay extra. Ask if they do a load calculation before sizing equipment. If they say they can eyeball it, hang up. That's hack work.
Red Flags
Big red flag: they demand full payment upfront. Reputable companies ask for a deposit — maybe half — and the rest on completion. Another one: they refuse to put the quote in writing. If they won't give you a typed, itemized estimate, walk. Also watch for high-pressure sales tactics like "this price is only good today." That's a lie. Real companies let you think it over. If the tech shows up in an unmarked van or can't produce an ID, that's another reason to send them away.
How Ratings Help You Choose
Online ratings are useful, but don't just look at the star average. Read the recent one- and two-star reviews. Look for patterns — do people complain about the same thing, like no-shows or upselling? A company with a few bad reviews that are all from years ago is fine. A company with a string of recent complaints about shoddy work is not. Also check how they respond to negative reviews. Defensive or nasty replies tell you a lot about how they handle problems. Good companies apologize and try to make it right.
