How to Read an HVAC Quote in Phoenix
Most homeowners see a number at the bottom and either accept it or shop for the cheapest. Neither approach protects you. Here is every line item explained — what's fair, what's padding, and what to ask before you sign.

In 19 years of doing this work, the most common thing I hear after a bad experience with another company is: “I didn't know what I was agreeing to.”
A legitimate HVAC quote is not complicated — but it does require specific information. If a quote is vague, that vagueness usually protects the contractor, not you. Here is how to read it.
— Brian Sorensen, Owner
Every Line Item — Explained
Equipment
50–60% of totalRed flag: Vague brand listing like "14 SEER unit" without a model number. You should see a specific model. Google it. Check the AHRI certificate.
What to ask: Ask for the ARI/AHRI matched efficiency certificate — this confirms the equipment actually delivers its rated efficiency.
Labor
25–35% of totalRed flag: Flat "installation fee" with no hours listed. Quality installation takes 4–8 hours for a standard residential swap.
What to ask: Good labor means: proper vacuum pull on the refrigerant lines, new disconnect, torque-tested fittings, verified static pressure. Ask if they do these.
Refrigerant
$0–$200 for new systems (pre-charged)Red flag: Large refrigerant charges on a new system. New systems come pre-charged. Extra refrigerant usually means a leak was patched rather than fixed.
What to ask: If you're replacing an R-22 system (pre-2010), disposal of the old refrigerant should be included — ask explicitly.
Permits
$150–$400 depending on cityRed flag: No permit line item. Arizona requires permits for HVAC replacement. Unpermitted work = problems when you sell the home.
What to ask: Surprise, Peoria, Glendale all require permits. A contractor who skips this is cutting corners somewhere else too.
Disposal
$50–$150Red flag: Missing entirely. Someone has to haul away your old unit.
What to ask: Confirm old equipment removal is included. Some quotes drop this and add it later.
Warranty
10-year parts, 1-year labor minimumRed flag: "Standard warranty" with no specifics. Get it in writing: what's covered, for how long, who honors it if the company closes.
What to ask: Manufacturer warranty (parts) ≠ contractor warranty (labor). You need both. A 10-year parts warranty is useless if the installation fails in year 2 and labor isn't covered.
7 Questions to Ask Before You Sign
What AHRI-matched system are you installing? Can I see the certificate?
Is this a Manual J load calculation or a rule-of-thumb size?
What does the installation include — vacuum pull, new disconnect, static pressure check?
Is the permit included? Who pulls it?
What's your labor warranty, separate from the manufacturer warranty?
Are refrigerant disposal and equipment haul-away included?
What happens if there's a problem in year 3 and you're no longer in business?
How We Quote at Sorensen
We give you a line-item quote — equipment model and AHRI number, labor hours, permit cost, disposal, warranty terms. No lump sum.
Our technicians are salaried, not commission-based. They don't earn more by recommending a bigger system or extra services. They recommend what your house actually needs.
We pull all required permits. Every job. It's the law — and it protects you.
We don't quote over the phone. We size equipment based on a Manual J load calculation — not by looking at what size came out. Oversized systems short-cycle, don't dehumidify, and fail faster.
