Why These Questions Matter
Replacing an HVAC system is one of the largest purchases a homeowner makes — typically $6,000–$15,000 depending on the system, home size, and complexity. Most homeowners do it once or twice in their lifetime, which means they're making a major financial decision with very little experience or context.
The HVAC industry knows this. That's why some companies rely on high-pressure sales tactics, "today only" pricing, and confusing good-better-best presentations designed to push you toward the most expensive option. The antidote is knowing what to ask — and knowing what a straight answer sounds like.
Questions to Ask Any HVAC Contractor
1. "How did you determine the size I need?"
The right answer involves a load calculation — considering your home's square footage, insulation, window area, orientation, ductwork, and local climate. In Southern Utah, sizing matters more than in moderate climates because the system works at or near full capacity for months. Whether you're in St. George or Cedar City, correct sizing is non-negotiable.
A red flag: "We'll just put in the same size you had before." The previous system may have been wrong. Or your home may have changed (additions, new windows, insulation upgrades). Same-size replacement without verification is lazy, not safe.
2. "What brand and model are you recommending, and why?"
There's no single "best" brand. But there should be a reason behind the recommendation — reliability track record, warranty terms, parts availability, suitability for your climate, or value at the price point. If the answer is just "it's what we install," that's not a reason.
Also ask: "Do you install multiple brands, or just one?" A contractor locked into a single brand may be recommending what they have, not what fits your situation best.
3. "What's included in the price — and what's not?"
A complete replacement quote should include: equipment, labor, refrigerant, thermostat (if upgrading), permit (if required), disposal of old equipment, and any necessary modifications to ductwork, electrical, or drainage. Ask specifically about:
- Is the thermostat included or extra?
- Are there any electrical upgrades needed?
- Is duct modification included if the new unit requires it?
- What about the disconnect, pad, or line set?
- Is there a warranty on labor, or just equipment?
4. "What efficiency level makes sense for my situation?"
Higher SEER ratings mean lower operating costs — but they also mean higher upfront costs. In Southern Utah, where AC runs 6–7 months a year, the payback on higher efficiency is faster than in moderate climates. But there's a point of diminishing returns.
A good contractor will help you understand the tradeoff: "A 16 SEER system costs $X more than a 14 SEER, and you'll save roughly $Y per year in energy costs. Payback is about Z years." That's a decision you can make with real numbers, not marketing language.
5. "What does the warranty cover, and for how long?"
Most manufacturers offer 5–10 year parts warranties, but many require registration within 60–90 days of installation. Labor warranties vary by contractor — some offer 1 year, some offer 5, some offer none. Ask specifically:
- How long is the parts warranty?
- How long is the labor warranty?
- Who handles warranty claims — you or the contractor?
- Is there anything that voids the warranty?
6. "Will you look at my existing ductwork?"
New equipment connected to old, leaky, undersized, or damaged ductwork won't perform as designed. A responsible contractor should at least inspect the ductwork and flag any obvious issues. If they're quoting a system without ever looking at the ducts, they're guessing.
This is especially important in Southern Utah homes built during rapid construction periods — particularly in Hurricane and Washington — where ductwork quality varies significantly.
7. "Can I see the quote in writing before I decide?"
Any contractor who pressures you to sign immediately — "this price is only good today" — is using a sales tactic, not offering a fair deal. A legitimate quote should be valid for at least 30 days. You should be able to take it home, compare it, and make a decision without pressure.
8. "Who's doing the actual installation?"
Some companies send a salesperson to your home and then dispatch a different crew for installation. Ask who's doing the work, how experienced they are, and whether the person quoting the job will be involved in the installation.
With a one-person operation like Bret's, this question answers itself — the person who quotes it is the person who installs it. There's no handoff, no miscommunication, no "that's not what I was told."
Red Flags to Watch For
- "Today only" pricing — Legitimate businesses don't change their prices based on whether you sign in the next hour.
- No load calculation — If they're quoting without measuring or calculating, they're guessing at the size.
- Pressure to upgrade unnecessarily — Not every home needs a variable-speed, two-stage, smart-enabled system. Sometimes a straightforward single-stage unit is the right fit.
- Vague pricing — "It'll be around $8,000–$12,000" isn't a quote. It's a range designed to anchor you high.
- No written warranty — If the labor warranty isn't in writing, it doesn't exist.
How Bret Handles Replacement Quotes
Bret's approach is simple: he looks at your home, sizes the system correctly, recommends equipment that fits your situation and budget, and gives you a clear written price. No good-better-best presentation. No "today only" discount. No pressure to decide on the spot.
He installs what he quotes, warranties his labor, and answers his phone if something comes up after installation. It's not complicated — it's just how things should work when you're spending $6,000–$12,000 on something that needs to keep your family comfortable for the next decade.
