More Frequently Asked Questions
How Often Should I Service My HVAC System?
To keep your HVAC system running efficiently, it should be serviced at least once a year– ideally twice: once in the spring for your air conditioning and again in the fall for your heating system. Regular maintenance helps prevent costly breakdowns, improves energy efficiency, and extends the lifespan of your system.
What’s the Best Thermostat Setting to Save on Energy Bills?
Homeowners can cut energy costs by setting their thermostat to:
- 68°F in winter while home, lower at night or away
- 78°F in summer when home, higher when away
Use a smart thermostat to adjust automatically for max efficiency
Why Is My Furnace Blowing Cold Air?
If your furnace isn’t heating, check for these common homeowner issues:
- Thermostat set to “On” instead of “Auto” – Change it to Auto.
- Dirty air filter – Replace it if clogged.
- Pilot light is out (for gas furnaces) – Relight if necessary.
- Overheating shut-off – The system may be shutting down due to overheating.
If your furnace keeps blowing cold air, it could be a bigger problem.
How Can I Improve My Home’s Indoor Air Quality?
Poor indoor air can lead to allergies, dry air, and breathing issues. Improve indoor air quality by:
✅ Changing HVAC filters every 1-3 months
✅ Installing a whole-home air purifier to remove allergens
✅ Using a humidifier to balance humidity in winter
✅ Adding UV lights to eliminate bacteria and mold
✅ Sealing air ducts to prevent dust buildup
How Do I Know If My HVAC System Needs Repair?
If your heating or cooling system isn’t working right, watch for these warning signs:
🚨 Uneven temperatures in different rooms
🚨 Unusual noises like banging or rattling
🚨 Higher energy bills with no explanation
🚨 Weak airflow or poor heating/cooling
🚨 Bad odors (burning, musty, or rotten egg smell)
If you’re experiencing any of these issues, don’t wait—small problems can turn into expensive repairs. Mammoth Mechanical offers 24/7 emergency HVAC repairs across Northern Michigan.
How Long Does an HVAC System Last?
Most HVAC systems last:
- Furnaces: 15-20 years
- Air Conditioners: 10-15 years
- Heat Pumps: 10-15 years
- Ductless Mini-Splits: 15-20 years
Regular maintenance can extend the lifespan of your system and prevent expensive repairs. If your HVAC is over 10 years old and breaking down often, it may be time for a replacement.
How Much Does a New Furnace Cost in Northern Michigan?
The cost of a new furnace depends on:
- System type: Gas, electric, or heat pump
- Efficiency rating (AFUE %) – Higher efficiency saves money long-term
- Size of your home – Larger homes need more powerful systems
- Installation complexity – Ductwork changes or custom solutions can add cost
Mammoth Mechanical helps Northern Michigan homeowners find the right furnace at the best price.
What Are the Benefits of a Heat Pump in Michigan’s Climate?
Many homeowners are switching to heat pumps because they:
- Provide heating & cooling in one system
- Are energy-efficient, reducing utility costs
- Work well in Michigan’s climate with cold-weather models
- Qualify for rebates & tax credits
Heat pumps work best in well-insulated homes and can be paired with a furnace for dual-fuel efficiency.
Why Is My Energy Bill So High in Winter?
If your energy bills are higher than usual, it could be due to:
- Poor insulation – Heat escapes through walls, windows, and doors.
- Old furnace – Older models are less efficient and work harder.
- Lack of maintenance – Dirty filters and worn-out parts cause inefficiency.
- Inefficient thermostat settings – Lowering your heat by 7-10°F at night can save you money.
If your bills are climbing, a furnace tune-up or system upgrade may help.
What’s the Difference Between a Furnace and a Boiler?
Many Northern Michigan homeowners ask whether they need a furnace or a boiler:
- Furnace: Uses forced air (ducts and vents) to heat your home.
- Boiler: Uses water and radiators to distribute heat.
- Furnaces are better for quick, even heating and are the most common choice.
- Boilers provide radiant heat, which can feel more comfortable and reduce allergens.
Why Are HVAC Repairs So Expensive?
HVAC repairs can feel pricey, but here’s what you’re paying for:
- Specialized expertise – HVAC techs undergo years of training and licensing.
- High-quality parts – Cheap parts lead to short-term fixes. We only use high-quality parts.
- Labor-intensive work – Diagnosing and fixing HVAC issues isn’t a quick job.
- Technology costs – Modern HVAC systems are more complex, requiring advanced diagnostics.
