Commercial HVAC Energy Efficiency Guide: How Calgary Businesses Save 20-30% Yearly Your commercial HVAC system is likely one of your three largest energy consumers—along with lighting and hot water. For a typical 10,000 sq ft Calgary office building, HVAC costs run $4,000-$6,000 per year. That’s 30-40% of total energy bills. What if you could reduce that by 25%? That’s $1,000-$1,500 in annual savings. Over 15 years (typical system lifespan), that’s $15,000-$22,500 in savings. More than enough to pay for a new high-efficiency system. At Purcell Commercial HVAC, we’ve helped Calgary businesses optimize HVAC efficiency. This guide walks you through understanding efficiency ratings, improving your current system, and determining if replacement pays for itself. FAST FACTS: HVAC Efficiency Average Savings Opportunity: 20-30% reduction in energy costs Quickest Win: Filter changes (DIY, $20, saves $100-$200/month) Biggest Win: System replacement/upgrade ($25,000-$60,000, ROI in 5-10 years) Maintenance Impact: Proper maintenance = 15-20% efficiency boost Thermostat Impact: Smart setpoint = 3-5% savings per degree Federal Rebates: Up to $5,000 available for high-efficiency upgrades Payback Period: Most upgrades pay for themselves in 7-10 years Part 1: Understanding HVAC Efficiency Ratings SEER (Seasonal Energy Efficiency Ratio) – Cooling Efficiency What It Is: SEER measures air conditioning efficiency. It’s the ratio of cooling output to electrical input. The Scale: 10-12 SEER = Old system (pre-2010) 13-15 SEER = Standard modern system 16-18 SEER = High-efficiency 19+ SEER = Premium/VRF systems What It Means in Dollars: For a typical 8,000 sq ft office building cooled 120 days/year: Old System (10 SEER):      $3,600/year cooling Standard System (15 SEER): $2,400/year cooling  [Save $1,200] High-Eff System (18 SEER): $2,000/year cooling  [Save $1,600] Premium System (20 SEER):  $1,800/year cooling  [Save $1,800] Calgary Context: Calgary gets ~120 cooling days/year (moderate) Cooling is secondary concern (heating dominates) SEER important but not as critical as AFUE AFUE (Annual Fuel Utilization Efficiency) – Heating Efficiency What It Is: AFUE measures furnace heating efficiency. It’s the percentage of fuel converted to usable heat. The Scale: 80% AFUE = Old gas furnace (very inefficient) 90% AFUE = Standard modern furnace 94-96% AFUE = High-efficiency 97%+ AFUE = Premium condensing furnace What It Means in Dollars: For a typical 8,000 sq ft office building (Calgary heating, ~200 days): Old Furnace (80% AFUE):    $6,000/year heating Standard (90% AFUE):       $5,333/year heating  [Save $667] High-Eff (95% AFUE):       $5,053/year heating  [Save $947] Premium (97% AFUE):        $4,907/year heating  [Save $1,093] Calgary Context: Calgary heating season = 200+ days Heating is PRIMARY concern (vs. cooling) AFUE matters more than SEER for Calgary Combined Impact (Heating + Cooling) For Calgary building, realistic energy breakdown: Heating: 60-70% of HVAC energy Cooling: 20-30% of HVAC energy Ventilation: 10% of HVAC energy Example: 10,000 sq ft office building OLD SYSTEM (80% AFUE / 10 SEER): Heating: $6,000/year Cooling: $3,600/year Total: $9,600/year NEW SYSTEM (95% AFUE / 18 SEER): Heating: $5,053/year Cooling: $2,000/year Total: $7,053/year ANNUAL SAVINGS: $2,547 (26% reduction!) 10-Year Savings: $25,470 20-Year Savings: $50,940 System Cost: $40,000-$50,000 installed Payback Period: 16-20 years from energy alone But: With rebates ($3,000-$5,000) + extended system life (20 vs. 15 years), payback becomes 12-15 years Part 2: 10 Ways to Improve HVAC Efficiency (Ranked by ROI) #1: Change Filters Regularly (Highest ROI – 400% ROI) The Issue: Clogged filters reduce airflow = system works 30-40% harder = wasted energy The Fix: Check filter monthly Replace when gray/dirty (typically every 30-60 days) Cost: $15-$40 per filter Expected Savings: Per filter change: Saves $100-$150 in electricity Annual impact: $1,200-$1,800/year energy savings Annual cost: $60-$120 (filters) Net savings: $1,080-$1,740/year Why This Wins: Cheapest intervention Biggest percentage impact Easiest to do yourself Action: Set calendar reminder. Change filters yourself monthly. #2: Smart Thermostat Settings (300% ROI) The Issue: Most buildings set thermostat at constant 70°F all day/night. This is wasteful. The Fix: Winter: 68-70°F during business hours, 62-65°F after hours/weekends Summer: 76-78°F during business hours, 82°F after hours/weekends Each degree = 3-5% energy impact Expected Savings: For a building using 4°F setback (70°F→66°F) nights and weekends: Annual savings: $800-$1,200 Cost of programmable thermostat: $200-$400 Payback: 2-6 months Why This Works: 40% of a building’s energy used after hours Setbacks eliminate heating/cooling unused spaces ROI fastest of any efficiency measure Action: Get a programmable thermostat ($200-$400). Program setback schedule. #3: Preventative Maintenance (250% ROI) The Issue: Dirty coils, low refrigerant, misaligned components = 15-25% efficiency loss The Fix: Quarterly maintenance service Annual deep cleaning Preventative repairs Cost: $1,200-$2,400/year Expected Savings: Efficiency improvement: 15-20% (from maintenance alone) Annual savings: $1,500-$2,000 Cost: $1,500-$2,000/year Net: Break-even to $500 savings Calculation – Long-term: 10 years NO maintenance: $96,000 energy + $5,000 emergency repairs = $101,000 10 years WITH maintenance: $80,000 energy + $18,000 maintenance = $98,000 SAVINGS: $3,000 over 10 years Plus: System lasts 5 years longer ($25,000+ value) Total 20-year benefit: $28,000+ Action: Enroll in quarterly maintenance plan ($300-$600/service). #4: Coil Cleaning (200% ROI) The Issue: Calgary’s dry air + dust = condenser coils get dirty. Dirty coils reduce efficiency 10-20%. The Fix: Professional coil cleaning (not DIY) Annual or every 2 years depending on location Cost: $200-$400/cleaning Expected Savings: Efficiency improvement: 10-20% Annual savings: $1,000-$1,500 Cost per cleaning: $300 Payback: 2-4 months Why Calgary Specifically: Dry air = dust accumulation faster Outdoor units exposed to Calgary weather Regular cleaning essential Action: Schedule annual coil cleaning (autumn recommended). #5: Ductwork Sealing (180% ROI) The Issue: Leaky ducts lose 10-20% of conditioned air before it reaches rooms. The Fix: Professional ductwork inspection ($100-$200) Seal leaks with mastic/tape ($500-$1,500) Cost: $600-$1,700 total Expected Savings: If 15% duct leakage found: $1,200-$1,800/year energy savings Cost: $1,000 Payback: 7-12 months How to Find Leaks: Professional uses smoke test or thermal imaging Can’t be found by visual inspection Worth getting diagnosed Action: Request ductwork inspection during next maintenance visit. #6: Refrigerant Charge Verification (150% ROI) The Issue: Systems charged incorrectly (too much or too little) lose 5-15% efficiency.

What’s the setpoint temperature? Example: Cooler setpoint: 38°F Actual temperature: 48°F Problem: 10°F too warm = potentially unsafe food Step 2: Check for Obvious Blockage (5 minutes) Go outside (or to mechanical room) to find the condenser: Is it covered in leaves, dirt, ice? Is air flow blocked? Can you see through the coil fins? ✓ If blocked: Clear leaves/debris around unit Use garden hose (LOW pressure) to rinse condenser Wait 30 minutes Check temperature again Cost: Free Expected improvement: 5-15°F temperature drop ✗ If not blocked: Proceed to Step 3 Step 3: Listen to Compressor (2 minutes) Is compressor humming/running? Or is it completely silent? If silent: Compressor not running = electrical or control issue Cost to fix: $300-$1,200 If running loudly: Compressor working hard but not keeping up Cost to fix: $400-$2,500 (usually refrigerant or compressor issue) Step 4: Check for Frost/Ice (2 minutes) Look at evaporator coil inside cooler: Visible? (Usually in back top area) Is it frosted over? (Some frost is OK, excessive is not) Is it iced solid? If iced solid: Defrost cycle not working properly Cost to fix: $200-$600 (defrost control or sensor replacement) Step 5: Call for Professional Diagnosis (necessary) Refrigeration is complex. After visual checks, call us: (403) 701-8661 Provide temperature reading + what you’ve checked We’ll do refrigerant charge check + electrical test Cost: $150-$300 diagnostic fee Response time: EMERGENCY (within 1-2 hours) Issue #2: Ice Machine Not Making Ice Severity: Medium-High (business disruption) Most Likely Cause: Water blockage (40%), compressor issue (30%), thermostat (20%), mold (10%) DIY Fix Possible: Partially Diagnosis Step 1: Check Water Supply (2 minutes) Is ice machine connected to water line? Is water valve turned ON? Any visible leaks? If water not flowing: Check water valve (should be open) Check if line is frozen (in winter) Check if water filter is clogged Step 2: Check Compressor (1 minute) Is compressor running (listen/feel for vibration)? Is it cold to the touch? (Should be warm if running) Step 3: Check for Mold (1 minute) Look inside ice bin Any black/green growth? Smell: anything unusual? If mold present: Don’t use ice Machine needs sanitization Call us for professional cleaning: $150-$300 Step 4: Call For Service (necessary) Ice machines need refrigerant diagnostics Can’t be fixed DIY beyond water issues Cost: $200-$1,000 depending on issue Response time: 24-48 hours (non-emergency) Issue #3: Cooler/Freezer Running Constantly Severity: Medium (energy cost impact) Most Likely Cause: Door seal leak (40%), thermostat (20%), compressor issue (20%), low refrigerant (20%) DIY Fix Possible: Yes, partially Diagnosis Step 1: Check Door Gasket (3 minutes) The rubber seal around the door: Is it torn or deteriorated? Does it seal completely when closed? Can you see light coming through? ✓ If seal is bad: Replace gasket ($50-$150 + labor) Expected improvement: Compressor runs 30-50% less Cost to fix: $100-$200 Energy savings: $30-$50/month Step 2: Check Door Operation (2 minutes) Does door close fully? Is there a gap? Do hinges need adjustment? ✓ If door doesn’t close fully: Adjust hinges (may DIY if comfortable) Or call for adjustment ($50-$100) Step 3: Check Evaporator Coil (visible from inside) Frosted over? (Some is OK) Iced solid? (Problem) Covered in dust/mold? (Problem) If excessively frosted/iced: Defrost cycle may not be working Compressor can’t keep up Call for professional service: $200-$500 Step 4: Monitor Energy Bills (ongoing) Is electric bill higher than normal? Compressor running constantly = high electric use Track cost impact Issue #4: Water Leaking From Cooler/Freezer Severity: Medium (water damage risk) Most Likely Cause: Drain blockage (50%), condensate drain frozen (30%), door seal (20%) DIY Fix Possible: Partially Diagnosis Step 1: Locate the Drain (2 minutes) Walk-in coolers have drains: Usually in floor (might be slightly elevated) Look for small PVC pipe or grate Should be visible inside unit Step 2: Check for Blockage (3 minutes) Visual inspection: Is standing water visible? Or is drain flowing freely? If drain appears blocked: Get small wire Gently poke into drain opening Try to break up blockage (algae/ice) Pour water down drain from nearby Cost: Free Expected result: Water drains freely Step 3: Check for Frozen Drain (in winter) If drain is blocked with ice: This is serious (water can’t drain out) May need to shut down cooler temporarily Call us for insulation/heating solution: $200-$400 Step 4: Check Door Seal (mentioned above) If door seal leaks, water pools underneath Fix seal (see Issue #3) Step 5: Monitor for Mold (important) Water = mold growth risk Check regularly for black growth Clean with dilute bleach solution If mold present: Call for professional sanitization Issue #5: Condenser Noise Getting Louder Severity: Low-Medium (noise issue, possible mechanical issue) Most Likely Cause: Fan bearing wear (40%), loose components (40%), compressor issue (20%) DIY Fix Possible: No Diagnosis Step 1: Describe the Noise (1 minute) Rattling? → Loose bolt/component Grinding? → Bearing wear (serious) Hissing? → Refrigerant leak (serious) Squealing? → Fan bearing (needs attention) Step 2: Check for Obvious Looseness (2 minutes) Look
