6 worked HVAC Contractors case studies — the position a client typically comes to us with, what we do, and what it is worth. Each is an illustrative example built on the rules that apply to hvac contractors work, not a specific client's file.
Case Study 1 · Missed incentive claimed
$121,000 Credit Claim Filed And Accepted Without Adjustment — Mechanical and HVAC Contractor, London
Client: A mechanical and HVAC contractor. Where: London, Ontario. Engagement: 4 weeks, fixed fee.
Claim value$121,000
AcceptedWithout adjustment
RepeatableAnnually
Case 1: the situation
A mechanical and HVAC contractor in London, Ontario assumed the credits did not apply to a business its size. Provincial credits left unclaimed alongside every federal filing meant they had applied all along.
Case 1: what we did
We identified the qualifying activity and built the documentation to support it. Then we rebuilt the chart of accounts around how a HVAC contractors business actually earns and spends.
Case 1: the result
$121,000 recovered. Because the eligibility analysis is on file, the same claim can be repeated each year with a fraction of the effort.
Case Study 2 · Scaling without breaking
Scaled To 20 Staff With $119,000 Of Working Capital Freed — Electrical Contractor, Brampton
An electrical contractor in Brampton, Ontario was growing fast, with headcount reaching 20 in eighteen months. The back office had not kept up. A chart of accounts that told the owner nothing about HVAC contractors margin was the first thing to break.
Case 2: what we did
We documented the positions to the standard the CRA applies to this sector specifically. We built the compliance calendar for the size the business was becoming rather than the size it had been.
Case 2: the result
The business reached 20 staff with no missed remittance and no late filing. $119,000 of working capital was freed in the process.
Case Study 3 · Cash and remittance control
$30,000 Of Working Capital Freed From The Tax Cycle — Civil Works Company, Kitchener
Client: A civil works company. Where: Kitchener, Ontario. Engagement: 4 weeks, fixed fee.
Working capital freed$30,000
On-time remittancesEvery period since
Forecast horizon13 weeks
Case 3: the situation
A civil works company in Kitchener, Ontario was profitable on paper and short of cash every month. Equipment and asset classes assigned by guesswork rather than the CCA schedule explained most of the gap.
Case 3: what we did
We reassigned the asset classes on the CCA schedule and corrected the opening balances. We also built a thirteen-week cash view so tax payments stopped competing with payroll for the same dollars.
Case 3: the result
$30,000 was released back into working capital. Remittances have been on time every period since, and the forecast shows the tax outflow before it lands.
Case Study 4 · Deadline rescue
Filed On Time From A Standing Start, $45,000 Penalty Avoided — Excavation and Site-Services Company, Victoria
Client: An excavation and site-services company. Where: Victoria, British Columbia. Engagement: 8 weeks, fixed fee.
Penalty avoided$45,000
Turnaround8 weeks
FiledOn time
Case 4: the situation
An excavation and site-services company in Victoria, British Columbia came to us 8 weeks before its filing deadline. The file came with industry-specific reporting obligations nobody had flagged. A late filing would have triggered a penalty of roughly $45,000 before interest.
Case 4: what we did
We worked backwards from the deadline. We reviewed every sector-specific deduction against the current rules and claimed the ones that had been missed. We prioritised the items that actually gated the filing and deferred everything that did not.
Case 4: the result
The return was filed on time and complete. The $45,000 penalty never arose, and the compliance calendar we set means the next deadline is scheduled rather than discovered.
Case Study 5 · Structure rebuilt
Corporate Structure Rebuilt For $20,500 Of Annual Savings — Custom Home Builder, Moncton
Client: A custom home builder. Where: Moncton, New Brunswick. Engagement: 9 weeks, fixed fee.
Saving per year$20,500
DocumentationComplete
Transfer basisRollover
Case 5: the situation
The structure at a custom home builder in Moncton, New Brunswick dated from years earlier. It had been set up for a business that no longer existed. Seasonal revenue reported without matching the costs that produced it had become expensive.
Case 5: what we did
We aligned the reporting calendar with the sector’s own seasonal cycle rather than a generic year-end. The reorganisation used the rollover provisions rather than a taxable transfer, so no tax fell due on the restructuring itself.
Case 5: the result
$20,500 of annual saving, achieved on a tax-deferred basis. The minute book, elections and valuations are all in the file.
Case Study 6 · Sale and succession
Intergenerational Transfer Completed With $335,000 Deferred — Drywall Subcontractor, Kelowna
Client: A drywall subcontractor. Where: Kelowna, British Columbia. Engagement: 9 weeks, fixed fee.
Tax deferred$335,000
TransferCompleted
RecordsReview-ready
Case 6: the situation
A generational transfer at a drywall subcontractor in Kelowna, British Columbia had been discussed for years without a plan. Passive assets sitting inside the operating company, disqualifying the shares meant the transfer as contemplated would have been fully taxable.
Case 6: what we did
We rebuilt the chart of accounts around how a HVAC contractors business actually earns and spends. We sequenced the steps so each one was complete and documented before the next depended on it.
Case 6: the result
$335,000 of tax was deferred through the transfer, and the successor generation took over a corporation whose records stood up to review.
