If you manage more than one commercial HVAC unit in Las Vegas, NV, a service contract is almost always cheaper than paying per visit. But not all service contracts are structured the same way, and the wrong contract can leave you paying for visits that don’t actually cover what breaks. This post walks you through what a commercial HVAC service contract in Las Vegas, NV should include, what the pricing structures mean, and how to evaluate a contract proposal line by line.
At Constant Air Balancing & Services, we write service contracts for commercial clients across Las Vegas, Henderson, Paradise, Spring Valley, and Enterprise. Here is the checklist we use ourselves when evaluating competitive proposals on behalf of building owners.
What Should a Commercial HVAC Service Contract Include?
A complete contract lists scope, frequency, pricing, response time, exclusions, and term. Anything missing is a negotiation opening. Here is the full list we recommend asking about:
- Equipment list — every unit by make, model, serial, age, and location. The contract covers these units specifically.
- Service frequency — quarterly, twice a year, monthly. With calendar dates.
- Scope per visit — line-item tasks, not “standard service.” See our 10-item list in the commercial HVAC service post.
- Filter program — is filter cost included? How often? What MERV rating?
- Parts and labor inclusions — full-coverage vs labor-only vs maintenance-only.
- Emergency response time — how fast after a call. 24 hours? 4 hours? Same day?
- After-hours rates — clearly spelled out. Usually 1.5x to 2x regular.
- Exclusions — what’s NOT covered (equipment over X years, refrigerant, compressor replacements, etc.).
- Term + renewal — 1, 2, or 3 years. Auto-renew or not.
- Written reports — delivered within X days of each visit.
What Are the Common Commercial HVAC Contract Tiers?
Most commercial HVAC contracts in Las Vegas, NV follow one of three tiers:
| Tier | Covers | Typical Cost |
|---|---|---|
| Maintenance-only | Scheduled PM visits + written reports. Repairs and parts billed separately. | $1,200 to $3,500/year for a 10K sq ft building |
| Labor-only | PM + all labor for repairs. Parts billed separately at cost. | $2,500 to $6,000/year for a 10K sq ft building |
| Full-coverage | PM + all labor + all parts. Some exclusions (compressors over X years, refrigerant). | $5,000 to $15,000/year for a 10K sq ft building |
Full-coverage sounds appealing but carries heavy exclusions that shift risk back to you. Labor-only is the middle ground most building owners settle on.
What Should the Emergency Response Clause Say?
Las Vegas, NV summer is not a climate where a 48-hour response is acceptable on cooling failure. A usable emergency response clause:
- Response time: 4 to 8 hours for cooling failures in summer, 24 hours for all other calls.
- After-hours rate: explicitly stated, not a wildcard “at our standard rates.”
- Dispatch priority: contract customers before non-contract, written in the agreement.
- Diagnostic visit fee waiver (or credit) for contract holders.
What Are Reasonable Exclusions?
Every commercial HVAC service contract excludes something. Reasonable exclusions include:
- Equipment older than 15 years (repair risk too high)
- Refrigerant charge beyond a set dollar cap per year
- Major component replacements (compressor, heat exchanger) — often available as add-ons
- Damage from acts of nature, water intrusion, vandalism
- Work on controls or BAS not originally installed by the servicer
Unreasonable exclusions: anything vague like “at contractor discretion” or “subject to additional evaluation.”
Should My Contract Include Filters?
Usually yes, especially if you have 2+ rooftop units. Contract filter programs typically get 20% to 40% better pricing than pay-as-you-go, and you never run late on a change. Verify the MERV rating — MERV 8 to 11 is standard for commercial. Anything higher needs confirmation your system can handle the static pressure.
How Should Pricing Be Structured?
Annual flat fee paid quarterly is the industry standard. Monthly billing is fine if cash flow matters. Avoid contracts that price per-visit with no commitment — you lose the discount and the priority benefits.
What Contract Red Flags Should I Watch For?
- Auto-renewal with a tiny notice window (30 days or less)
- Price escalator clauses with no cap
- “Subject to field conditions” language on the scope
- No written list of equipment covered
- Exclusions for all refrigerant (common but should be a line item, not a full block)
- No termination clause (you need the ability to exit for non-performance)
How Long Should the Contract Term Be?
One year for a first contract. Two to three years once you’ve established trust with the contractor. Longer terms usually come with discounts but lock you in if service quality drops.
Should a Commercial HVAC Service Contract Include Air Balancing?
Often no, by default. Air balancing is usually a separate scope billed per occurrence. But if your building has had recurring comfort complaints, you can negotiate a yearly spot-balance (check a sample of 25% of diffusers, re-adjust if drifted) into the service contract. Constant Air Balancing & Services writes these into contracts regularly.
How Do I Evaluate Two Competing Contract Proposals?
Line the two side by side on:
- Equipment list — do both cover the same units?
- Visit frequency — how many visits per unit per year?
- Scope per visit — the 10 line items above
- Response time + after-hours rate
- Exclusions — compare side by side, flag anything one has that the other doesn’t
- Total annual cost ÷ number of visits — effective per-visit rate
If one proposal is 30% cheaper, the scope is almost certainly lighter. Read the fine print before signing.
