Question DetailsAsked on 12/14/2017

how can I be sure that I hire a good hvac person to do a conversion to refrigerated air? How do I check them out?

I have gotten different estimates and am ready to hire company for a conversion to refrigerated air. How can I verify their credentials? I found one through home advisors, the other through tv ads. Help!

You say "conversion" to refrigerated air - do you mean adding A/C to a forced air system - or maybe putting in A/C in a house which uses steam or hot water or electric heating ? OR do you mean you currently have chilled water or swamp cooler cooling ?

Anyway, here are a couple of links to previous similar questions on the subject - including one detailing my thoughts on selecting a good HVAC contractor.

The key is to get estimates on a system design which "works" for your house - meaning designed using the ACCA Manuals to determine the cooling (and heating) load, figure the size (design capacity) unit needed, then the distribution system (ducts or mini-split units) and venting and such required to properly address your HVAC heating/cooling conditions. THEN, when system capacity and such is determined, decide (either initially, or sometimes by getting two system options in the bids) whether you want a standard or high efficiency unit and what rating, whether you want/can use a standard A/C unit or a Heat Pump which both cools and heats, figure what brand names you consider acceptable, THEN get competitive bids on the scope of work which has been defined. Otherwise, you will get bids on mismatched systems and varied efficiencies and such so you will be comparing bids for apples and oranges and lemons.

On Angies List, the thing to do is join (there are both free and paid memberships, with varying levels of service and benefits, all of which allow you to Search the List ("The List" being "Angie's List"), using the button at left endof green banner bar above. Once you are registered as a user, then you go to Search the List and search by category (Heating and A/C in this case) for local vendors, and to look at their ratings (A-F like a report card) and the written Reviews from previous customers.

One other thought - personal opinion, but I don't recall any service (as opposed to goods/products) company which advertised on TV which was economic or one I would really trust - they shytsters seem to be the ones using TV/radio to advertise, and especially with TV if they are spending money to buy TV ads that is going to drive their cost up quite a bit so they are likely to be quite a bit more expensive.

FYI - here is a link to an Angies List articleon bonding, insurance, licensing, etc which might be of interest if you are not familiar with those - lack of those should rule out some of the competitors and many of the shady firms:

Good Luck
