Industry Insights](https://blog.armsolutions.com/blog/author/a-r-m-industry-insights) Oct 6, 2026, 1:40:31 PM · 5 min read [HVAC](https://blog.armsolutions.com/blog/tag/hvac) Summer is when finance teams can unknowingly create their largest accounts receivable risk. For many HVAC contractors, especially those servicing commercial facilities, schools, office buildings, property management companies, and industrial sites, summer revenue looks strong on paper. The challenge is that a significant portion of those invoices may not convert to cash as quickly as expected. Many CFOs and finance leaders assume commercial accounts are lower risk because they represent established businesses rather than individual consumers. While commercial customers generally offer greater payment stability, they can also create some of the most expensive collection problems when past-due invoices are not addressed early. As noted in internal A.R.M. positioning materials, delays often originate from approval processes, documentation issues, or payment bottlenecks rather than a simple refusal to pay. Early intervention helps identify and resolve those issues before balances age into serious collection challenges. ## Why Summer Creates Unique AR Challenges for HVAC Companies The summer season places extraordinary demands on commercial customers and HVAC contractors alike. Large-scale projects are completed quickly. Service departments are overloaded. Billing teams are processing higher invoice volumes than normal. Accounts payable departments at customer organizations are often managing competing priorities and increased spending requests. As a result, invoices that should have been paid within 30 days can quickly age into 60-, 90-, or even 120-day receivables. The longer an account remains unresolved, the more difficult recovery becomes. What appears to be a temporary delay can gradually evolve into: - Lost documentation - Invoice disputes - Purchase order discrepancies - Staff turnover at the customer - Budget approval issues - Cash flow constraints - Collection disputes By the time a balance reaches 120+ days, the original issue is often harder to identify and resolve than it was at day 30. ## The Myth of the "Good Commercial Customer" Many finance leaders hesitate to escalate commercial accounts because of a long-standing relationship. The thought process is understandable: - They've always paid eventually. - They're a large customer. - We don't want to damage the relationship. - The account manager says they'll take care of it. Unfortunately, these assumptions can create unnecessary write-off exposure. A commercial customer can be valuable and still have an invoice trapped in an approval workflow. A facility manager may support payment while the AP department waits for documentation. A project manager may have moved on to another role, leaving nobody responsible for approving the invoice. Waiting longer rarely solves these issues. Proactive follow-up does. ## Signs an HVAC Invoice Should Be Escalated Not every past-due invoice needs immediate third-party intervention. However, certain indicators suggest the account requires a higher level of attention. ### The Customer Stops Providing Specific Payment Dates Responses like: - "We're working on it." - "The check is being processed." - "I'll have someone look into it." often indicate the payment process has stalled. If multiple follow-up attempts fail to produce a firm payment commitment, escalation should be considered. ### The Invoice Exceeds 60 Days Past Due For many commercial HVAC contractors, 60 days represents an important threshold. At this point, resolution becomes less about standard collections and more about identifying what's preventing payment. The earlier this investigation begins, the greater the likelihood of recovery. ### The Balance Is Significant Large commercial projects can create invoices worth thousands or tens of thousands of dollars. Even one unresolved account can materially impact cash flow, borrowing requirements, and profitability. When invoice values rise, finance teams should prioritize rapid resolution over extended waiting periods. ### Multiple Invoices Are Aging With the Same Customer A single late invoice may be an anomaly. Several past-due invoices often indicate a systemic issue that requires intervention. Early action helps prevent a manageable situation from becoming a portfolio-level problem. ## Why Early Intervention Works Many organizations think of collections as a last resort. Modern commercial recovery strategies are far different. According to A.R.M. messaging and commercial AR guidance, successful recovery often involves identifying approval delays, missing documentation, AP workflow obstacles, and other root causes that are preventing payment. Early intervention can help: ### Identify the Real Reason for Nonpayment The invoice may be: - Sitting in an approval queue - Missing supporting documentation - Assigned to the wrong contact - Delayed by a purchase order issue - Held up by a billing dispute Finding the root cause quickly is often the difference between payment and write-off. ### Improve Recovery Rates The probability of collecting an invoice generally decreases as account age increases. Engaging additional resources earlier gives organizations more opportunities to resolve issues before accounts become severely delinquent. ### Preserve Customer Relationships Perhaps the biggest misconception in commercial collections is that escalation damages relationships. Professional early-stage recovery efforts focus on communication, problem-solving, and documentation rather than confrontation. When handled correctly, escalation actually helps maintain relationships by bringing clarity and resolution to overdue accounts. ## What HVAC CFOs Should Track Right Now As summer invoices begin moving through AR aging reports, finance leaders should monitor: - Total receivables over 60 days - Total receivables over 90 days - Concentration of aging by customer - Average days sales outstanding (DSO) - Number of invoices awaiting dispute resolution - Commercial accounts with repeated payment delays These metrics often reveal collection risks before they become write-offs. ## The Cost of Waiting The biggest collection mistake is not necessarily having overdue invoices. It is assuming that time alone will solve the problem. Every month spent waiting increases collection costs, reduces visibility into the underlying issue, and places additional pressure on cash flow. For HVAC companies coming off a busy summer season, the goal should not simply be generating more invoices. It should be converting those invoices into cash as efficiently as possible. The most successful finance teams understand that escalation is not an admission of failure. It is a proactive accounts receivable strategy. Early intervention gives commercial customers the opportunity to resolve issues while they are still manageable. Waiting until an account is approaching write-off status often leaves far fewer options available.
