Short answer: The Better Business Bureau (BBB) assigns letter grades from A+ to F based on a company's complaint history, responsiveness to complaints, business transparency, and length of time in operation. Accreditation is separate from the rating — it means the business has applied, paid a fee, and agreed to BBB standards. A high BBB rating with few complaints is one useful data point when evaluating HVAC contractors, but it should be combined with license verification, Google review analysis, and direct reference checks. The Cooling Company holds an A+ BBB rating with zero unresolved complaints. You can verify any HVAC company's BBB profile for free at bbb.org.
Key Takeaways
- BBB ratings are letter grades, not star ratings: The scale runs from A+ (highest) to F (lowest). The grade is calculated from 17 factors including complaint volume relative to business size, complaint resolution history, time in business, and government action history.
- Accreditation and rating are different things: A non-accredited company can still have an A+ rating. Accreditation means the business voluntarily agreed to BBB standards and pays an annual fee. The rating is assigned by BBB based on performance data regardless of accreditation status.
- Complaint count matters more than rating alone: A company with an A+ rating but 47 complaints in three years tells a different story than an A+ company with zero complaints. Always check the complaint detail page, not just the letter grade.
- BBB does not verify quality of work: The BBB tracks complaints and dispute resolution. It does not inspect installations, verify licensing, or evaluate technical competence. A high BBB rating means the company handles complaints well — not necessarily that the work is excellent.
- Use BBB as one data point among several: Combine BBB data with Nevada State Contractors Board license verification, Google reviews, and direct references for a complete picture of any HVAC contractor.
How BBB Ratings Are Calculated
The BBB uses a proprietary algorithm that weighs 17 factors to produce a letter grade. The most heavily weighted factors are complaint history, complaint resolution, and government or legal actions against the business. Here is a simplified breakdown of the major categories:
Complaint volume relative to size: The BBB considers how many complaints a company receives relative to its size and the length of time it has been in business. A company with 5 complaints in 10 years weighs differently than a company with 5 complaints in its first year. HVAC companies that serve thousands of customers per year will naturally receive more total complaints than a one-truck operation — the ratio matters more than the raw number.
Complaint resolution: This is the factor that most directly affects the letter grade. When a customer files a BBB complaint, the company has 30 days to respond. The BBB tracks whether the company responded, whether the customer was satisfied with the response, and whether unresolved complaints remain open. Companies that ignore BBB complaints see their ratings drop quickly. Companies that respond promptly and resolve issues maintain high ratings even if they receive occasional complaints.
Time in business: Newer companies start with less data, which can affect their rating. A company that has operated for 15 years with a clean complaint record carries more weight than a company with a clean record but only 6 months of history. In the HVAC industry, where fly-by-night operations are a real concern during peak summer season, longevity is a meaningful signal.
Transparency: The BBB evaluates whether the company provides clear information about its business practices, including licensing, ownership, and contact information. Companies that are difficult to reach or provide incomplete information score lower.
What Accreditation Means (and Does Not Mean)
BBB accreditation is a voluntary program. A company applies to the BBB, agrees to adhere to BBB's Standards of Trust (eight principles including honesty in advertising, transparency, and responsiveness to complaints), and pays an annual fee that varies by business size and market.
What accreditation signals: the company has voluntarily submitted to BBB oversight, agreed to resolve disputes through BBB's process, and is willing to be held publicly accountable for its complaint record. For HVAC companies, this is a positive signal — it indicates the company is invested in its reputation and willing to engage with a third-party dispute resolution process.
What accreditation does not signal: BBB accreditation does not mean the BBB has verified the quality of the company's HVAC installations, inspected their work, or tested their technical competence. The BBB is a dispute resolution and business ethics organization, not a trade licensing body. Accreditation should never substitute for verifying a company's Nevada State Contractors Board license, which is the legal authority that governs HVAC work quality and contractor competence.
How to Look Up Any HVAC Company on BBB
Checking a company's BBB profile is free and takes about two minutes:
- Go to bbb.org
- Enter the company name and location (e.g., "Las Vegas, NV") in the search bar
- Click the company's listing to view the full profile
- Review the letter grade displayed at the top of the profile
- Scroll down to the "Customer Complaints" section — this is the most important part
- Click into individual complaints to read the full exchange between the customer and the company
Pay particular attention to complaint patterns. A single complaint about a billing error is very different from multiple complaints describing the same issue — such as repeated reports of no-shows, unfinished work, or refusal to honor warranties. Patterns in complaint types reveal systemic problems that a letter grade alone may not capture.
What Complaint Counts Indicate
The BBB complaint section is the most valuable part of any company profile. Here is how to interpret the data:
Zero complaints: This is uncommon for companies that have been in business for more than a few years and serve a high volume of customers. For an HVAC company operating in a market as large as Las Vegas, zero complaints over a meaningful time period indicates strong customer service and dispute resolution processes — or a very small operation with limited exposure.
Low complaint volume with full resolution: A company with 2-5 complaints over three years, all marked as resolved, is demonstrating normal business friction handled properly. HVAC work is inherently complex, and occasionally a customer experience falls short. What matters is how the company responds.
High complaint volume or unresolved complaints: If an HVAC company has dozens of complaints, or complaints marked as "unanswered" or "unresolved," that is a serious warning sign. It may indicate the company is overwhelmed, undermanaged, or indifferent to customer concerns. Multiple unresolved complaints should disqualify a contractor from your consideration.
Government action flags: The BBB profile may note if government agencies have taken action against a company. For HVAC contractors in Nevada, this could include disciplinary actions from the Nevada State Contractors Board (NSCB). Any government action flag warrants further investigation before hiring that contractor.
What BBB Ratings Cannot Tell You
BBB data has real limitations that homeowners should understand:
- Technical competence: The BBB does not evaluate whether an HVAC company sizes systems correctly, charges refrigerant properly, or installs ductwork to code. Those evaluations fall under the NSCB licensing process and local building inspections.
- Pricing fairness: The BBB does not compare or evaluate pricing. A company with an A+ rating may charge significantly more or less than competitors for the same work.
- Installation quality: The BBB cannot tell you whether a company's AC installations will last 10 years or 20 years. That depends on technical execution, not complaint history.
- Employee qualifications: BBB accreditation does not require that technicians hold specific certifications, EPA cards, or manufacturer training credentials.
This is why BBB data should be combined with other verification steps. Check the contractor's Nevada license status, read Google reviews for depth and patterns, verify their bond amount, and ask for references from recent installations similar to yours.

Frequently Asked Questions
Can a company pay for a higher BBB rating?
No. BBB accreditation requires an annual fee, but the letter grade itself is calculated independently based on complaint data, business history, and transparency. A non-accredited company can receive an A+ rating if its complaint record is clean. A paying, accredited company can receive a low grade if it accumulates unresolved complaints. The fee pays for participation in the accreditation program, not for the rating.
Should I avoid a company that is not BBB accredited?
Not necessarily. BBB accreditation is voluntary, and many reputable HVAC companies choose not to participate. The absence of accreditation does not indicate a problem — it simply means the company has not applied or chosen to pay for the program. Focus on the company's rating (which BBB assigns regardless of accreditation), their complaint history, and other verification sources like the Nevada State Contractors Board.
How far back do BBB complaints go?
The BBB typically displays complaints from the past three years on a company's public profile. Older complaints may no longer appear but can still influence the company's rating calculation. For HVAC decisions, three years of complaint data is generally sufficient to identify patterns.
