Normal HVAC Noises 1. Soft Humming A gentle hum is totally normal, especially near the indoor blower or outdoor condenser. It usually means the motor is running like it should. 2. A Click When It Turns On or Off Clicking once at startup or shutdown is expected — that’s your thermostat and relays doing their job. But frequent or rapid clicking? That’s another story. 3. Gentle Air Whooshing Airflow through the vents should sound like a soft whoosh — not a whistle or roar. If it’s consistent and not aggressive, you’re good. Sounds That May Signal Trouble 1. Banging or Clanking Loud banging, especially when the system kicks on, often means something is loose or broken — like a blower wheel or motor mount. Think of this as your HVAC’s version of a red flag. 2. Buzzing or Electrical Sounds A steady buzz could point to electrical issues, such as a failing capacitor or loose wiring. If your system is buzzing but not turning on, it’s best to stop using it and call us right away. 3. High-Pitched Whistling This usually means restricted airflow — possibly due to a clogged filter, closed vent, or duct leak. It can cause your system to work harder than it should. 4. Hissing A faint hiss might just be airflow — but a loud or persistent hissing could signal a refrigerant leak (especially in ductless mini splits or heat pumps). That’s something to address quickly for both safety and performance. 5. Rattling If it sounds like something’s vibrating against metal, it could be a loose screw or panel — or even debris in the outdoor unit. Sometimes it’s minor, but it’s still worth checking out before it gets worse. What You Can Do First ✅ Check your air filter — a clogged one causes all sorts of airflow issues ✅ Make sure vents are open and not blocked by furniture ✅ See if the outdoor unit is free of leaves, sticks, or ice ✅ Listen carefully: Where is the sound coming from — the vents, inside unit, or outside? 🔧 When to Call AirTech If the noise is loud, persistent, or paired with other issues (like poor airflow or no heat/AC), don’t wait — give us a call. We’ll track down the cause and get your system running smoothly again — and quietly. Need help with a noisy HVAC system in Bellingham? Contact us today at 360-734-5010 to schedule a service visit.

The good news? With a few easy thermostat tweaks and system tips, you can make your bedroom the perfect sleep haven. 💤 1. Find Your Ideal Sleeping Temperature Experts say the best bedroom temperature for sleep is between 60 and 67 degrees Fahrenheit. A cooler room helps your body naturally lower its core temperature — a key step for falling (and staying) asleep. If your home runs warm at night, try lowering your thermostat a few degrees about an hour before bed. In winter, experiment with lowering the heat just enough to stay cozy without overheating under the covers. 🕰️ 2. Use a Programmable or Smart Thermostat Don’t want to get up and fiddle with the thermostat every night? Let technology do it for you! A programmable thermostat lets you set a consistent nighttime schedule so your system automatically adjusts. Even better, a smart thermostat learns your habits — and some models can be controlled from your phone, whether you’re in bed or on vacation. 🧘 3. Keep Air Flowing & Humidity in Check A stuffy room can make sleep uncomfortable. Make sure vents aren’t blocked by furniture, curtains, or piles of laundry. If your bedroom feels humid (common in Bellingham’s rainy months), consider using a dehumidifier or an HVAC system with built-in humidity control. Balanced humidity helps you breathe easier and keeps your bedding feeling fresh. 🔇 4. Silence Noisy HVAC Equipment A rattling vent or loud fan can ruin your rest. If your system is making unusual noises, it might be time for a tune-up. Routine maintenance can help your furnace or AC run quietly and efficiently — so strange sounds don’t wake you at 2 AM. 🌙 5. Consider Zoning for Better Comfort If some family members like it warm and others want it cold, a zoned HVAC system can solve the bedtime thermostat battle. Zoning lets you set different temperatures for different areas of your house — so everyone sleeps comfortably. Sleep Better Tonight Your HVAC system works around the clock — why not make it work for your sleep schedule too? If you’re ready to upgrade to a programmable thermostat, add zoning, or need help quieting down your system, AirTech Heating & Hydro Mechanical Inc. is here to help Bellingham homeowners rest easy. Contact us today to learn more or schedule a tune-up — and sweet dreams!

If you have a dog, cat, rabbit, or a whole menagerie running laps through your living room, you already know your pets make your house feel like a home. But have you ever stopped to think about what your HVAC system thinks about them? (Hint: it’s a love–hate relationship. ) Your pets shed hair, dander, and dirt — and guess where all that stuff loves to hang out? Yup. In your air filters, vents, and ductwork. Here in Bellingham, with our mix of damp fall days and humid summers, all that pet hair and moisture can make your system work overtime if you’re not careful. Don’t worry, though! With a few easy tweaks, you can keep your heating and cooling system purring along — no matter how many paws are on patrol. 1. Change Your Filters More Often Pet hair is basically air filter kryptonite. A home with pets should ideally have its filters swapped out every 1–2 months — not every 3 months like the petless folks can get away with. It’s an easy job that keeps your system breathing easy. 2. Brush the Fur, Beat the HVAC Strain The more fur you brush off your pet, the less ends up drifting into your return vents. Regular grooming is a win-win: your dog looks dapper, your cat struts around like a runway model, and your HVAC doesn’t have to fight through a felt blanket of pet fuzz. 3. Vacuum, Vacuum, Vacuum We know — it’s no one’s favorite chore. But a quick run of the vacuum (especially around vents, registers, and baseboards) picks up the hair and dander before it can sneak into your ductwork. Your allergies — and your system — will thank you. 4. Protect Outdoor Units Dogs love to mark their territory, and unfortunately, your AC condenser might look like a great spot to them. Pet urine can corrode parts of your unit over time. Fencing off the area or using shrubs as a barrier keeps the curious canines at bay. 5. Check Those Ducts Over time, dander can build up in ductwork. If you’ve had your pets for a while (or you’ve adopted a new furry friend), it’s smart to have your ducts inspected and cleaned periodically to keep air flowing freely. 6. Consider an Air Purifier If you have multiple pets or someone in your house has allergies, an air purifier or upgraded filtration system can be a game-changer. Cleaner air means less strain on your HVAC and a healthier home for everyone. Final Thoughts: HVACs Love Pets Too (Kind Of) We love our four-legged family members — and so can your HVAC system, as long as you show it some extra TLC. A few extra chores now can help you avoid unexpected breakdowns, big repair bills, and cranky summer afternoons when the AC gives up in protest. Got questions about your pet-friendly HVAC setup?

When was the last time you thought about your furnace or heat pump? If you’re like many Bellingham homeowners, your heating system might be quietly working away — but is it costing you more than it should? With rising energy costs and our wet, chilly winters, having an efficient, reliable HVAC system is more important than ever. Here’s how to know when it’s time to consider an upgrade — and what you can expect. 1️⃣ Signs Your Heating System May Be Due for an Upgrade High Energy Bills: If your power bills keep climbing but your comfort stays the same, your system may be losing efficiency. Frequent Repairs: Needing repairs more than once every couple of years? It may be time for a new system rather than patching the old one. Uneven Heating: Cold spots or rooms that never warm up can mean your system isn’t distributing heat properly. Age of System: Most furnaces last 15–20 years. Heat pumps typically last 10–15 years. If yours is older, upgrading could pay off quickly. Noisy Operation: Strange noises or constant cycling can indicate wear and tear that’s better solved with a replacement. 2️⃣ Benefits of a New High-Efficiency HVAC System Modern heating systems are designed to keep you comfortable and reduce wasted energy — something every Bellingham homeowner can appreciate. ✅ Lower Utility Bills: New systems can cut heating costs by 20%–40% compared to older models. ✅ Better Comfort: Advanced systems distribute heat evenly and maintain more consistent temperatures. ✅ Environmental Benefits: More efficient systems reduce your carbon footprint — good for you and the planet. ✅ Smart Features: Many new furnaces and heat pumps integrate with smart thermostats for even more savings. 3️⃣ Choosing the Right Heating System for Bellingham Our mild but damp climate means you have options. Heat pumps are popular in Bellingham because they provide efficient heating in winter and cooling in summer. For colder homes or older buildings, a modern high-efficiency gas furnace may be the better fit. Not sure which is right for you? A professional HVAC contractor (like us!) can help you compare options and pick the best solution for your home and budget. 4️⃣ Rebates & Incentives Good news for Bellingham homeowners: Local utility companies often offer rebates for installing energy-efficient HVAC systems. We can help you find and apply for rebates to save money on your upgrade. ✅ Ready to Talk Heating Upgrades? At AirTech Heating & Hydro Mechanical Inc., we’ve been helping Bellingham homeowners stay warm and comfortable for years.

There’s something timeless about gathering around a wood stove. The warmth, the flicker of flame, and the gentle crackling of logs—it creates an atmosphere no electric heater can match. But beyond the ambiance, indoor wood stoves can also be an efficient and effective heating solution for many homes in the Bellingham and Whatcom County area. And right now, we have select wood stove models on sale in our showroom— plus mini splits, A/Cs, fireplaces, and more! Swing by for a great chance to upgrade your home heating while saving money. Ask about our top-of-the-line Kuma wood stoves! Why Homeowners Love Wood Stoves 1. Reliable Heat During Power Outages One of the biggest perks of a wood stove is that it doesn’t rely on electricity. In rural areas or during Bellingham’s winter windstorms, this can be a game-changer. When the grid goes down, a well-installed wood stove keeps your home warm—no backup generator needed. 2. Cost-Effective Heating With the right setup and dry, seasoned wood, wood stoves can supplement (or sometimes replace) your primary heating source and help lower energy bills. In areas where firewood is accessible and affordable, this can make a noticeable difference. 3. Strong, Even Heat Modern EPA-certified stoves are designed to burn wood efficiently, giving off steady, long-lasting heat with fewer emissions than older models. The radiant heat they provide warms both the air and surrounding surfaces, creating a cozy and consistent temperature throughout the room. What to Consider Before Installing a Wood Stove 1. Proper Sizing and Placement A stove that’s too small won’t heat effectively. Too big, and you’ll end up overheating the room and wasting fuel. Placement also matters for heat distribution and safety. We always recommend a professional evaluation to find the right fit for your space. 2. Venting and Chimney Requirements Wood stoves need a well-functioning flue or chimney to safely vent smoke and combustion gases. If you're replacing an old stove or converting a fireplace, the chimney may need to be relined or upgraded to meet current safety codes. 3. Clearance and Fire Safety Clearance from walls and combustibles, hearth pad requirements, and heat shields all factor into a safe installation. Our technicians make sure every install meets Whatcom County and manufacturer safety standards. 4. Maintenance and Upkeep Wood stoves require regular ash removal, chimney cleaning, and inspection to keep them operating safely. We offer maintenance services to help you stay ahead of creosote buildup or ventilation issues. 🔧 Ready to Shop?

Even though we’re well into spring here in Bellingham, the nights are still chilly enough that your furnace may not be completely off duty. If you’ve turned on the heat recently and noticed a strange burning smell, you’re not alone—and it’s something worth paying attention to. As a local HVAC company in Bellingham, we get a lot of calls this time of year from homeowners wondering whether that odor is normal or a sign of trouble. Here’s what you need to know. Common Causes of That Burning Smell 1. Dust on the Furnace Heat Exchanger In spring, many heating systems are running less frequently. When your furnace sits idle for days (or weeks), dust naturally settles on components like the heat exchanger. When the system kicks back on, that dust burns off, creating a faint burning smell. This is usually harmless and should go away after a cycle or two. 2. Clogged Air Filters If your furnace has to work harder to pull air through a dirty filter, it can overheat. That extra heat may produce a burning odor. In some cases, the motor may be stressed, which can shorten the life of your system. Replacing your filter is a quick, inexpensive fix—and something our heating repair technicians can help with if needed. 3. Electrical or Mechanical Issues A burning plastic or metallic smell could indicate a more serious problem, such as overheating electrical components or a malfunctioning blower motor. If the smell is strong or persistent, turn off your system and call for HVAC service in Bellingham right away. When to Call a Professional If the burning smell lasts longer than a few heating cycles, or if you notice smoke, unusual sounds, or performance issues, it’s time to schedule a service call. These could be signs of something more dangerous, like a short circuit or damaged wiring—issues that should never be ignored. Our team at AirTech Heating & Hydro Mechanical Inc. is trained to quickly diagnose and resolve heating repair issues before they lead to bigger problems. We’re currently booking maintenance appointments about 1–2 weeks out, and we’d be happy to take a look if your system is acting up. Stay Ahead of Summer—And Stay Safe Spring is also a great time to make sure your system is ready for warmer weather. If you haven’t already scheduled your AC maintenance, it’s the perfect opportunity to do both. We offer inspections and tune-ups for both heating and AC repair in Bellingham, so you’re covered year-round. Have questions or smelling something unusual?

If you're looking into air conditioner installation in Bellingham, you're probably wondering: What type of system should I choose? Is Lennox a good brand? And what does the installation process actually involve? Whether you're replacing an outdated unit or upgrading for better comfort and efficiency, it's a big decision—and we're here to help you feel confident about it. At AirTech Heating & Hydro Mechanical Inc., we install and service a wide range of air conditioning systems, including trusted brands like Lennox. Let’s break down the basics of choosing an air conditioner, the benefits of Lennox systems, and what to expect from the installation process. Why So Many People Choose Lennox Air Conditioners Lennox is one of the most recognized names in home comfort for a reason. Their systems are built for energy efficiency, quiet performance, and smart technology integration. Models like the Lennox XC25 lead the industry with SEER ratings up to 26—meaning lower energy bills and better environmental impact. Homeowners who value long-term efficiency and lower operating costs often gravitate toward Lennox. Their systems work well with advanced thermostats and zoning solutions, and they qualify for many local rebates and federal energy credits. One thing to keep in mind: because Lennox uses proprietary parts, it’s important to have your system installed and maintained by a certified dealer. That’s where we come in. Understanding the Different Types of AC Systems Not every space needs the same kind of air conditioner. Here’s a rundown of the most common options we install and service: Central Air Conditioning is still the go-to for whole-home comfort. If you already have ductwork in place, it’s a reliable and efficient option. Lennox offers a wide range of central systems—from basic, budget-friendly models to ultra-efficient, variable-speed units that keep your home consistently cool with minimal noise. Ductless Mini-Split Systems are a smart choice for homes without ductwork, additions, or rooms that need separate temperature control. These systems are compact, energy efficient, and offer flexible installation. You’ll have a small outdoor unit and one or more sleek indoor heads mounted on the wall or ceiling. Heat Pumps are a popular option in the Pacific Northwest climate. They provide both heating and cooling in one system and are especially efficient in our mild winters and moderate summers. Lennox’s dual-fuel systems can also pair a heat pump with a gas furnace for year-round comfort and flexibility. Window or Portable AC Units are best for short-term use or small spaces. They’re not something we install as HVAC contractors, but they can be useful for renters or those needing quick relief without a larger investment. What Happens During an AC Installation? Installing a new air conditioning system isn’t just about dropping in new equipment—it’s a process that starts with careful planning. First, we assess your home’s layout, insulation, square footage, and any existing ductwork. Then we recommend a system that's properly sized—because an oversized or undersized unit can cause long-term issues with comfort and energy use. Once we’ve selected the right system together, we handle the full installation: removing the old equipment, setting up the new indoor and outdoor units, connecting refrigerant lines, calibrating controls, and thoroughly testing the system. We also walk you through how to use it and register your warranty. Whether you’re leaning toward a Lennox system or just starting to explore your AC options, we’re here to help you make the right call for your space and budget. At AirTech Heating & Hydro Mechanical Inc., we never cut corners, and we’re proud to provide expert installation and service to Bellingham and surrounding areas. 📞 Give us a call at 360-734-5010 or fill out our contact form to schedule a no-pressure consultation. We'll help you find a system that keeps you comfortable—and makes sense for the long haul.

When was the last time your HVAC system had a check-up? If the answer is “I’m not sure,” you’re not alone—but regular maintenance is one of the smartest (and most affordable) ways to protect your home comfort system. Here’s what routine maintenance looks like for different HVAC equipment, and what you can expect when a technician shows up. Why Maintenance Matters: Routine HVAC maintenance keeps your system running efficiently, safely, and reliably. It can help: Extend the life of your equipment Prevent breakdowns and costly repairs Lower your energy bills Keep indoor air cleaner and more comfortable Whether it’s your furnace, heat pump, air conditioner, or fireplace, a little seasonal upkeep goes a long way. What Maintenance Looks Like—By Equipment Type ✅ Furnace (Gas or Electric) Check and replace the air filter Inspect the heat exchanger for cracks or damage Clean the blower motor and housing Test safety controls and thermostat settings Verify proper venting and combustion (for gas units) Check for gas leaks or carbon monoxide issues 🛠 When? Once a year—typically in fall, before heating season kicks in. ✅ Air Conditioner or Heat Pump (Cooling Mode) Clean the condenser coils and remove debris Check refrigerant levels and pressure Inspect electrical connections and capacitors Clean or replace the air filter Test system performance and temperature split Ensure the condensate drain is clear 🛠 When? Once a year in the spring, before warm weather arrives. ✅ Heat Pump (Heating Mode) If your heat pump is used year-round, it needs twice-yearly service—once in spring and again in fall. You’ll want: Coil cleaning Filter check Refrigerant level check Electrical component test Thermostat calibration Fan and motor inspection 🛠 When? If your heat pump is used year-round, it needs twice-yearly service: once in spring and again in fall. ✅ Gas Fireplaces Clean the glass, burner, and logs Inspect the thermopile and thermocouple Test ignition and safety shut-offs Check for proper ventilation and gas leaks 🛠 When?

When the summer heat starts rolling in, your air conditioner becomes the MVP of your home. But one small part of your HVAC system plays a bigger role than most people realize: the air filter. We get a lot of questions about AC performance here at AirTech, especially when folks call us for AC repair in Bellingham. And honestly, one of the most common culprits is something simple—a dirty air filter. What Your Air Filter Does (And Why It Matters) Your HVAC filter traps dust, pollen, pet hair, and other debris before it can get inside the system. This helps keep the air in your home cleaner, sure—but more importantly, it protects your HVAC system from damage. If the filter is clogged, your system has to work harder to pull air through, and that can cause all kinds of issues: Weak airflow Higher energy bills Uneven cooling Extra wear on system components Over time, that extra strain can lead to breakdowns and the need for unexpected (and expensive) AC repairs. So... How Often Should You Change It? We recommend changing your filter every 1 to 3 months, depending on your lifestyle. Got pets? Allergies? Running the A/C a lot during hot stretches? You’ll want to check it monthly. Changing your filter is one of the easiest ways to avoid calling for emergency AC repair in Bellingham when the system quits on the hottest day of the year. Maintenance = Less Stress (for You and Your HVAC) Besides swapping filters, your A/C needs routine care—just like your car. Spring and early summer are great times to schedule a maintenance visit to make sure everything's running smoothly. A typical HVAC maintenance visit in Bellingham includes: Cleaning the condenser coil Checking refrigerant levels Inspecting and tightening electrical connections Lubricating moving parts Testing system performance and airflow This kind of upkeep helps you catch small issues before they turn into big repair bills. And if we do find something off, our licensed techs are ready to handle AC repairs in Bellingham quickly and professionally.
