How to Prepare for Your Furnace Service Call
8 Steps to Prepare for Furnace Service
Follow these preparation steps before our technician arrives to ensure fast, efficient diagnosis and repair of your heating system.
Clear Access to Your Furnace and Venting
Ensure our technicians can reach your furnace equipment quickly: Indoor Furnace/Air Handler: - Clear items stored around furnace closet, garage unit, or attic access hatch - Remove boxes, holiday decorations, or stored items from around furnace - Ensure attic access ladder is accessible and safe to climb (if applicable) - Turn on lights in furnace area (closets, garages, basements, attics) - Open any locked doors to furnace room Outdoor Components (if applicable): - Clear pathway to exterior venting (high-efficiency furnaces vent through sidewall) - Remove snow, leaves, or debris from PVC vent pipes - Trim back vegetation near venting areas Why This Matters: Clear access saves 15-30 minutes of service time, reduces your labor costs, allows technicians to work safely, and prevents delays in restoring your heat. When indoor temperatures are dropping on cold Tucson nights, every minute counts.
Document Heating Performance Issues
Write down specific symptoms you've noticed to help our technician diagnose quickly: Temperature Problems: - What temperature are you setting vs. what you're getting? - Are some rooms warmer/colder than others? - Does problem worsen during coldest overnight hours? - How long has furnace been underperforming? System Behavior: - Does furnace ignite then shut off immediately (flame sensor issue)? - Does furnace run continuously without reaching set temperature? - Do you hear clicking but no ignition (igniter or gas valve problem)? - Any unusual sounds (banging, rumbling, squealing, grinding)? - Any unusual smells (gas odor, burning dust, sulfur/rotten eggs)? Safety Concerns: - Has carbon monoxide detector ever alarmed near furnace? - Do you smell natural gas near furnace or gas meter? - Is pilot light yellow/orange instead of blue (incomplete combustion)? - Excessive condensation or water pooling near furnace? Recent Changes: - When did problem start? - Any recent power outages or electrical issues? - Any recent DIY work on furnace or thermostat? - When was last professional service? Why This Matters: Detailed symptom information helps technicians diagnose accurately on first visit, potentially avoiding return trips and getting your heat restored faster.
Locate Thermostat, Electrical Panel, and Gas Shutoff
Our technicians need access to critical system controls: Thermostat: - Remove furniture or artwork blocking thermostat - Note your normal temperature settings (take photo) - Check thermostat batteries (if applicable) and replace if low - Verify thermostat is set to HEAT mode (not OFF or COOL) Electrical Panel/Breaker Box: - Locate main electrical panel (garage, exterior wall, utility room) - Clear any items stored in front of panel - Identify furnace breaker (usually labeled "Furnace," "Heating," or "HVAC") - Note if breaker has tripped (switched to middle or OFF position) Gas Shutoff Valve (for gas furnaces): - Locate gas shutoff valve (usually on gas line near furnace) - Ensure valve handle is parallel to pipe (ON position) - Note location of main gas meter shutoff (emergency use only) Why This Matters: Quick access to these controls speeds diagnosis of electrical, thermostat, and gas-related issues. Understanding their locations also helps you communicate issues clearly and potentially identify simple causes (tripped breaker, thermostat set to wrong mode).
Check (But Don't Change) Your Furnace Filter
Locate your air filter and note its condition without removing it: Common Furnace Filter Locations: - Return air grille (often in hallway ceiling or wall) - Furnace cabinet (pull-out filter slot) - Behind decorative return vent cover What to Look For: - Can you see light through filter? (if no, it's very dirty) - What size is written on frame? (e.g., 20x25x1, 16x25x4) - When was it last changed? (write date on filter frame next time) - Is it the right type for your furnace (standard vs. HEPA)? Why Don't We Change It First? A dirty filter provides diagnostic information. It may be the root cause of heating problems (restricted airflow triggering safety shutdowns), or it may indicate other airflow issues like closed registers, blocked returns, or ductwork problems. Let our technician assess filter condition during diagnosis. Why This Matters: Filter condition reveals important clues about system operation, maintenance history, and potential causes of heating failures. A severely clogged filter can cause furnace overheating, triggering safety limit switches that shut down the system.
Gather Furnace System Information
Having system details ready speeds up diagnosis and parts ordering: Information to Locate: - Furnace brand and model number (on label on furnace cabinet) - Serial number (same label) - System age (check installation sticker or purchase records) - Fuel type (natural gas, propane, electric) - Previous maintenance records (if available) - Warranty information (if system is less than 10 years old) - Filter size (from filter frame) Where to Find This Info: - Furnace cabinet: Look for manufacturer label on front or side panel - Inside furnace door (some models) - Your home inspection report (if recent purchase) - Previous HVAC invoices or maintenance stickers - Original installation paperwork Why This Matters: Model and serial numbers help us verify warranty coverage, order correct replacement parts immediately if needed, and access manufacturer technical bulletins about known issues with your specific furnace model. This can save significant time and potentially save you money on parts covered under warranty.
Note Any Recent Household Changes
Inform technician of changes that might affect furnace operation: Electrical or Construction Changes: - Recent electrical work or panel upgrades - Remodeling that affected ductwork or vents - New gas appliances installed (water heater, stove, dryer) - Attic insulation added (can affect furnace ventilation) Thermostat or Control Changes: - New smart thermostat installed - Thermostat reprogrammed or settings changed - Home automation system added Environmental Changes: - Recent monsoon storms or power surges - Lightning strikes near home - Rodent activity in attic or near furnace area Why This Matters: Recent changes can directly cause furnace problems. For example, new attic insulation can block combustion air intake for older furnaces, new gas appliances can create backdrafting issues, and smart thermostats may have incorrect wiring. This context helps technicians diagnose faster.
Secure Pets and Notify Household Members
Prepare your household for our technician's arrival: Pet Considerations: - Secure dogs that might be protective (even friendly dogs) - Confine cats that might hide in furnace areas or escape through open doors - Alert technician to any pets via special instructions when scheduling Family Notification: - Let family members know technician will be working indoors - Furnace service requires accessing furnace area, attic, or utility room - May need to cycle furnace on/off multiple times during testing - Expect 45-120 minutes for diagnosis, longer for complex repairs - Temperatures may fluctuate during service as system is tested Why This Matters: Secured pets prevent service delays and ensure safety for both technicians and animals. Family awareness reduces interruptions during service and helps everyone understand why temperatures may temporarily drop or fluctuate during testing procedures.
Prepare Questions for Our Furnace Technician
Write down questions to make the most of your service call: Good Questions to Ask: - What caused this furnace problem? - How can I prevent this issue in the future? - Is this a sign of a bigger issue with my heating system? - Should I consider replacement vs. repair given furnace age? - What maintenance should I be doing myself? - Are there any safety concerns with my furnace or venting? - What's the expected lifespan of this repair? - Would a programmable thermostat save me money? - Am I eligible for utility rebates or tax credits on replacement? Questions About Costs: - What's included in this repair cost? - What warranty comes with parts and labor? - Are financing options available for furnace replacement? - Can you provide written estimate with breakdown? Why This Matters: Our technicians average 17+ years experience and are experts in heating systems. Ask questions—we're here to educate you, ensure your safety, and help your furnace run efficiently for years to come. There are no "dumb" questions when it comes to your family's comfort and safety.
Furnace Emergency Decision Guide
CALL EMERGENCY SERVICE (24/7) IF:
- ✓ You smell natural gas near your furnace or gas meter → EVACUATE immediately, call gas company from outside, then call us
- ✓ Carbon monoxide detector is alarming near furnace → Open windows, evacuate, call 911, then call us to inspect system
- ✓ Outdoor temperature is below 35°F AND you have no heat (frozen pipe risk in next 4-6 hours)
- ✓ Household members include elderly, infants, or medically vulnerable individuals who can't tolerate cold
- ✓ Indoor temperature has dropped below 55°F and continues falling (dangerous hypothermia risk)
- ✓ You see flames, smoke, or sparks coming from furnace area → Shut off furnace at breaker, call us immediately
- ✓ Furnace is making loud banging/explosion sounds on startup (delayed ignition—serious safety risk)
- ✓ Water is actively leaking/flooding from furnace area (high-efficiency condensate issue)
- ✓ You've lost heat during Arizona's coldest nights (December-February when temps drop to 25-30°F)
SCHEDULE NEXT-DAY SERVICE IF:
- • Outdoor temperature is mild (above 45°F) and you can tolerate indoor temps overnight with extra blankets/space heaters
- • Furnace is running but providing insufficient heat (partial operation)
- • You hear unusual sounds but furnace is still producing heat
- • You notice gradual performance decline over several days/weeks
- • It's late spring/summer and you're planning ahead for next winter
- • Your furnace is working but energy bills have increased dramatically
- • Pilot light keeps going out but you can relight it temporarily (older furnaces)
- • You want second opinion on furnace replacement recommendation from another company
CAN WAIT FOR REGULAR APPOINTMENT IF:
- • It's warm season (April-October) and you're scheduling annual maintenance
- • You want furnace efficiency evaluation before winter season
- • You're planning furnace replacement in next 1-2 months (proactive)
- • You're getting quotes for furnace installation in new home addition
- • Minor thermostat programming issues (we can troubleshoot via phone)
- • You want indoor air quality assessment or humidifier installation
Furnace Replacement vs. Repair Cost Analysis
Repair vs. Replace Decision Matrix:
- Furnace Age 0-5 Years: Almost always repair (under warranty). Cost: $150-800 typical. Exceptions: Major defects, lemon equipment.
- Furnace Age 6-10 Years: Usually repair unless major component (heat exchanger $1,800-2,800, compressor on heat pump $2,200-3,500). Balance repair cost vs. remaining useful life.
- Furnace Age 11-15 Years: Consider replacement if repair exceeds $1,200. Calculate: (Repair Cost) × (Age Factor) vs. (Replacement Cost After Rebates). If repair × age/10 > 50% of replacement cost, replace.
- Furnace Age 16-20 Years: Strongly consider replacement. Efficiency gains (80% AFUE → 96% AFUE) can save $400-800/year, rebates offset costs, and you avoid repeat repairs on aging equipment.
- Furnace Age 21+ Years: Replace in almost all cases. These furnaces use obsolete technology, lack replacement parts, and waste significant energy compared to modern high-efficiency systems.
Common Repair Costs (Tucson Average 2024):
- • Flame Sensor Cleaning/Replacement: $180-$285
- • Hot Surface Igniter Replacement: $250-$385
- • Limit Switch Replacement: $220-$350
- • Gas Valve Replacement: $450-$750
- • Blower Motor Replacement: $550-$950 (standard) | $800-$1,400 (variable-speed ECM)
- • Inducer Motor Replacement: $650-$1,100
- • Control Board Replacement: $400-$850
- • Heat Exchanger Replacement: $1,800-$2,800 (often not cost-effective vs. replacement)
- • Full Furnace Replacement (80% AFUE): $3,500-$5,200 installed
- • High-Efficiency Replacement (96% AFUE): $4,800-$7,500 (before $1,200-$3,200 in rebates/credits)
Financial Incentives That Change the Math:
- • Federal Tax Credit: Up to $2,000 for 96%+ AFUE gas furnaces or qualifying heat pumps (ENERGY STAR Most Efficient)
- • Tucson Electric Power (TEP) Rebate: $400-$1,200 for high-efficiency gas furnaces (95%+ AFUE)
- • Southwest Gas Rebate: $200-$600 for qualifying high-efficiency gas equipment
- • Financing Options: 0% APR for 60 months (with approved credit) makes monthly payments lower than energy savings
- • Energy Savings: Upgrading from 80% AFUE to 96% AFUE saves typical Tucson home $400-$800/year in winter heating costs
