When your AC sputters on a sweltering Saturday or your furnace groans on a frosty morning, peace of mind comes from knowing you’re prepared. At Briggs Heating, we know the difference regular HVAC maintenance makes. It’s the invisible shield—guarding your comfort, wallet, and safety from surprise breakdowns.

Ignoring routine care is like skipping oil changes in your car. Problems build up quietly, then strike when you least expect it. Whether you’re a homeowner, a property manager, or run a bustling business, this year-round checklist will help you keep your system humming—and help you know when to call for emergency hvac help.

Year-Round HVAC Maintenance: Monthly, Seasonal, and Annual Tasks 🛠️

Every heating and cooling system needs regular attention. Some jobs are quick and easy. Others need a pro’s tools and training. Here’s how to break it down:

Monthly To-Do’s

• Replace or check air filters. Dirty filters are HVAC’s silent enemy. According to the EPA, a clogged filter can reduce efficiency by up to 15%. For homes with pets or businesses with high foot traffic, check filters twice a month.
• Inspect vents and registers. Make sure they’re free of dust, debris, and obstructions like curtains or furniture.
• Listen for odd noises. Rattles, squeaks, or banging sounds are an early warning system.
• Monitor thermostat performance. If temperatures feel off or system cycles are odd, it’s time for calibration.

Seasonal Steps

Spring/Summer:

• Clear outdoor AC units. Remove leaves, twigs, or grass clippings from the area around your condenser.
• Test cooling before the first heatwave. Don’t wait for 95°F to discover your AC isn’t working.
• Check for leaks or pooled water. Moisture near the unit can signal blocked drains or refrigerant problems.

Fall/Winter:

• Check and test heating. Fire up the furnace before the first frost.
• Inspect pilot lights and burners. Look for steady blue flames—yellow or flickering may mean trouble.
• Seal up drafts. Inspect windows and doors to help your system work less.

Annual Must-Dos

• Schedule a professional tune-up. The EPA and most manufacturers recommend yearly service to extend your system’s life and uphold warranties.
• Get ductwork inspected. Leaky ducts waste energy and strain your system, especially in larger homes or commercial buildings.
• Test indoor air quality (IAQ). Especially important if you or your employees have allergies, asthma, or concerns about airborne particles.

What You Can Handle vs. When to Call a Pro

Some HVAC care is as simple as flipping a switch or changing a battery. Other jobs? Leave them to the trained eye of a Briggs Heating technician.

DIY-Friendly Tasks

• Swapping out air filters
• Dusting vents and returns
• Keeping outdoor units clear of debris
• Checking thermostat batteries

When to Call Briggs Heating

• Annual maintenance: Only a certified technician can safely test electrical components, refrigerant pressures, and combustion safety.
• Odd smells or noises: Burning, musty, or chemical odors can mean trouble.
• Poor airflow: Could signal a blocked duct, blower issue, or something more serious.
• Thermostat or control malfunctions: Modern systems have sensitive electronics that need a pro’s touch.

Commercial HVAC: Special Considerations for Businesses 🏢

Running a business? Your HVAC works overtime—and needs extra attention.

• Rooftop units: Exposed to the elements, these need regular coil cleaning and weather checks.
• Larger ductwork: More space means more opportunity for leaks, inefficiency, or contamination.
• Zone controls: Offices, kitchens, or server rooms may have specialized needs.
• Hood & exhaust systems: Especially in restaurants, these require routine inspection to avoid fire hazards.

A breakdown in a business isn’t just uncomfortable—it can mean lost revenue, product spoilage, or compliance risks. That’s why many commercial clients schedule preventative visits with Briggs Heating, especially before busy seasons.

Signs You Need Service—Don’t Wait for a Breakdown

Your HVAC system usually sends out distress signals before failing. Here’s what to watch for:

• Unexplained energy bill increases: A sudden spike often signals something’s working too hard.
• Hot and cold spots: Inconsistent temperatures can point to thermostat issues or failing components.
• Strange noises: Grinding, squealing, or popping are never normal.
• Persistent odors: Musty smells may indicate mold; burning smells could mean electrical hazards.
• Poor air quality: More dust, humidity problems, or allergy symptoms? Time for a checkup.

If you notice any of these, don’t wait—especially if temperatures outside are extreme. Emergency hvac service is always available from Briggs Heating.

Following Trusted Guidelines—Why It Matters

HVAC systems are complex. The U.S. Department of Energy, EPA, and major manufacturers like Trane and Carrier all stress the value of regular, professional maintenance. Whether it’s checking for refrigerant leaks (which can harm the environment) or calibrating gas furnaces for safety, following code and manufacturer recommendations isn’t just smart—it’s required for warranty and insurance in many cases.

Our technicians are continuously trained and follow the latest safety and efficiency guidelines on every call.

Practical Tips for Extending System Life

• Keep your filters clean.
• Don’t ignore small problems. A little noise today can become a big repair tomorrow.
• Upgrade thermostats if needed. Newer models offer better control and energy savings.
• Consider IAQ solutions: Air scrubbers, humidifiers, and dehumidifiers can protect your system and your health.
• Schedule regular maintenance: Like clockwork—spring and fall, every year.

Costs & Time Factors: What Should You Expect?

Most basic homeowner tasks (like changing a filter) take five minutes or less. Professional maintenance—thorough inspection, cleaning, and calibration—usually takes 60–90 minutes for residential systems. Commercial units may take longer due to their size and complexity.

Costs vary by system type, age, and any repairs needed. Catching issues early with routine checkups saves money over time and helps avoid after-hours emergency hvac bills.

When It’s an Emergency: What to Do First 🚨

If you lose heating or cooling when you need it most, don’t panic. Here are quick steps to take:

1. Check the basics: Is the thermostat set correctly? Has a breaker tripped?
2. Shut down the system if you smell gas or burning. Safety first.
3. Call Briggs Heating for 24/7 emergency hvac help. Our technicians are ready day and night.

If you manage a business, have employees or customers, or sensitive equipment, don’t wait—every minute counts.

Frequently Asked Questions

How often should I change my filter?

Most homes: every 1–3 months. More often if you have pets, allergies, or a busy business.

Is HVAC maintenance really necessary every year?

Absolutely. The EPA and all major manufacturers recommend annual professional maintenance to keep systems efficient, safe, and under warranty.

What are signs my system is failing?

Unusual noises, rising bills, uneven temperatures, or poor air quality are all red flags.

What’s included in a professional tune-up?

A typical visit includes inspecting electrical connections, refrigerant levels, safety controls, drain lines, blower motors, and more—plus cleaning and calibration.

Local and Seasonal Considerations

Hot, humid summers or frigid winters? Your HVAC works harder in extreme conditions. Schedule maintenance before peak seasons—spring for AC, fall for heating. If you’re in a region with wildfire smoke, ask about advanced filtration or indoor air quality testing.

Businesses with commercial kitchens, tech rooms, or large crowds should consider more frequent checks. And always keep emergency hvac support on speed dial for those unexpected moments.

Don’t let a small problem turn into a big headache. For reliable, thorough HVAC maintenance—at home or at work—choose Briggs Heating.
