Q: “How often should I really change my HVAC filter?”
A: More often than you think. The general guideline is every 90 days, but it depends on your home. If you have pets, allergies, or live in a high-dust area, every 30–60 days is better. Clean filters ensure proper airflow, protect your blower motor, and improve indoor air quality.
Q: “Do I really need annual maintenance if my system seems to be working fine?”
A: Absolutely. Think of HVAC maintenance like going to the dentist. You may not feel pain now, but preventative checkups catch small issues before they become major (and costly) repairs. A qualified HVAC contractor can detect motor wear, low refrigerant levels, dirty coils, and failing thermostats before they create an emergency.
Brands like Nardco Heating & Air Conditioning encourage proactive maintenance, not because it’s convenient, but because it’s cost-effective and increases system lifespan.
Q: “What’s the difference between furnace repair and a furnace replacement? How do I know which one I need?”
A: Good question—and a common one. A repair means fixing individual components like a heat exchanger, ignitor, or blower motor. Replacement, however, involves removing your entire furnace and installing a new unit. The decision often hinges on age (over 15 years is a key marker), frequency of issues, energy efficiency, and repair costs.
If your repair bills are stacking up or your furnace runs inefficiently despite tune-ups, replacement may be the smarter investment.
Q: “Is there an ideal thermostat setting for saving energy?”
A: Yes—and it depends on the season. In winter, 68°F when you’re home is a good balance of comfort and energy savings. In summer, 78°F is the recommended setting when you’re indoors. Use a programmable thermostat to automatically adjust these levels while you’re away or asleep. This reduces strain on your system and cuts down utility costs.
Q: “Why is one room always colder than the others?”
A: Uneven heating or cooling often comes down to poor ductwork design, blocked vents, insulation gaps, or aging equipment. Start by checking your vent positions, filters, and insulation in that room. If it persists, have an HVAC contractor conduct a system balance test. It may require adjusting duct dampers or correcting airflow imbalances within your setup.
Q: “How long does a typical furnace last?”
A: Most residential furnaces last between 15 and 20 years, depending on usage, maintenance, and brand quality. If your furnace is reaching this age and requires frequent service, it’s a sign that a more efficient system could better serve your home. Regular inspections will help you predict when a replacement might be needed.
Q: “Should I be concerned about strange furnace noises?”
A: Absolutely. Hissing, banging, or rattling can indicate loose components, ignition problems, or clogged burners. A quiet hum is normal, but anything beyond that deserves a quick look. These sounds are often the first signs that you’ll soon need furnace repair.
Letting them go unchecked increases the risk of a full system failure—and likely on the coldest day of the year.
Q: “How do I find a reliable HVAC contractor?”
A: Look for licensed, insured professionals with a proven track record. Seek out customer reviews, business certifications, and clear maintenance policies. Availability during emergency situations is a bonus. Companies like Nardco Heating & Air Conditioning typically offer long-standing community trust and technical expertise—qualities you want in a home service partner.
Q: “What’s involved in a furnace tune-up?”
A: A typical tune-up includes inspecting burners, testing for carbon monoxide, checking the heat exchanger, inspecting the flue, cleaning components, tightening electrical connections, and ensuring proper airflow. This process prevents unexpected failures and ensures safe operation all winter long.
Q: “How do I know if my HVAC system is too small or too large for my home?”
A: Improper sizing causes major issues. A system that’s too small won’t heat or cool effectively, while an oversized system short-cycles—turning on and off too quickly—causing excessive wear. A professional load calculation considers square footage, insulation, window exposure, and more. Don’t rely on guesswork or copy a neighbor’s setup.
Q: “Are smart thermostats really worth the upgrade?”
A: For most homeowners—yes. Smart thermostats can learn your preferences, track usage, and allow you to control your system remotely. Over time, they optimize energy usage and provide insights into efficiency. Paired with a well-maintained system, they help reduce wear and maximize comfort.
Q: “My system works, but my bills are still high. What gives?”
A: High utility bills with a functioning HVAC unit often point to reduced efficiency. Dirty coils, clogged filters, leaky ducts, or outdated equipment can all contribute. Regular maintenance helps improve system performance, and if your furnace or AC is more than 15 years old, you may want to explore energy-efficient upgrades.
Final Thought
Owning a home means managing comfort, energy, and safety—your HVAC system is central to all three. The more you understand how it works, the better prepared you’ll be for changes in temperature and system performance.
Whether you’re dealing with uneven airflow, strange noises, or higher energy bills, getting ahead of HVAC issues saves time and money. It also ensures your home remains the comfortable retreat it’s meant to be—year-round.
