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?

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.

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.

5 Unexpected Ways Spring Weather Can Affect Your HVAC System As Bellingham thaws out from winter and the days get longer, most of us are thinking about blooming flowers, open windows, and spending more time outside. But spring weather also brings some surprising changes that can affect your home comfort system. If you're not prepared, you might find yourself suddenly in need of AC repair in Bellingham or wondering why your allergies feel worse indoors than out. Here are five unexpected ways spring can impact your HVAC system, plus a few simple tips to stay ahead of the game: 1. Pollen & Allergens Overload Your Air Filters Spring is beautiful, but all that fresh air comes with pollen, dust, and other airborne allergens. These particles get pulled into your HVAC system and clog up your air filter faster than usual. That means more strain on your system and lower indoor air quality. When should I replace my air filter? During allergy season, it’s a good idea to check it every 30 days. If you see a visible layer of dust, swap it out. 2. Temperature Swings Can Confuse Your Thermostat One day it's sunny and warm, the next it's back to chilly mornings. These spring shifts mean your system might bounce between heating and cooling. If your thermostat isn't calibrated properly, your system could overwork itself trying to keep up. What is spring HVAC maintenance? It includes checking your thermostat settings, cleaning components, and making sure your system is running efficiently before summer hits. 3. Humidity Creeps Back In In Bellingham, spring rain and warming temperatures mean higher humidity levels. Too much indoor humidity can make your home feel muggy and cause your AC to run longer than necessary. It can also lead to mold or mildew in ductwork or air handlers. A well-maintained HVAC system helps control humidity. If your AC is running constantly, it might be time to schedule a service call for AC repair in Bellingham. 4. Critters Nest Where They Shouldn't Birds, squirrels, and other small animals love cozying up inside outdoor units or crawlspace ductwork. Nesting materials can block airflow, chew wires, or create hazardous buildup. Not sure if animals have been messing with your system? A quick inspection during your spring HVAC maintenance visit can catch these issues early. 5. Spring Storms Bring Debris Heavy winds and rain can blow leaves, sticks, or trash into your outdoor AC unit. This debris can damage fan blades or clog condenser coils, making your system work harder (and potentially fail sooner). Pro tip: After a storm, take a peek at your outdoor unit and clear away anything obvious. If you're not sure it's in the clear, give your local HVAC pros in Bellingham a call.

As the days grow longer and temperatures begin to rise, now is the perfect time to ensure your air conditioning system is ready for the season ahead. A little preventive maintenance in the spring can help you avoid costly repairs, improve efficiency, and extend the life of your system. Here’s why spring A/C maintenance is essential and what you can do to keep your unit in top shape. Why Spring A/C Maintenance Matters: Improved Efficiency – A well-maintained A/C unit runs more efficiently, lowering energy bills and reducing strain on the system. Prevention of Costly Breakdowns – Catching small issues early can prevent them from becoming expensive repairs during peak summer heat. Better Air Quality – Clean filters and coils help your system circulate fresher, healthier air throughout your home or business. Extended Lifespan – Routine maintenance helps extend the life of your HVAC system, protecting your investment. Signs Your A/C May Need Repairs Even with proper maintenance, issues can still arise. Keep an eye out for these warning signs that your A/C may need professional repair: Weak Airflow – If air isn’t circulating properly, it could be due to a clogged filter, duct issues, or a failing blower motor. Unusual Noises – Grinding, banging, or squealing sounds can indicate mechanical problems that need immediate attention. Warm Air from Vents – If your A/C is blowing warm air, it could be a refrigerant issue or a problem with the compressor. Frequent Cycling – If your system is constantly turning on and off, it may be struggling to maintain the set temperature due to a faulty thermostat or airflow problems. Water Leaks or Ice Buildup – Leaking water or ice formation on the coils can indicate blocked drainage or refrigerant issues. So, what does A/C maintenance look like? Spring A/C Maintenance Checklist: Replace or Clean Air Filters – Dirty filters restrict airflow, reducing efficiency and increasing energy consumption. Check your filters monthly and replace them as needed. Inspect and Clean Coils – Dust and debris can accumulate on evaporator and condenser coils, reducing heat exchange efficiency. Cleaning them improves performance. Check Refrigerant Levels – Low refrigerant can indicate a leak and lead to inefficient cooling. A professional technician can check and recharge your system if needed. Test Thermostat Functionality – Ensure your thermostat is accurate and programmed for optimal cooling efficiency. Inspect and Clear Drain Lines – Clogged drain lines can cause moisture buildup, leading to water damage or mold growth. Check Electrical Components – Loose or damaged electrical connections can cause system failures. An inspection by a technician can ensure safe operation. Lubricate Moving Parts – Proper lubrication reduces friction and wear on essential components. Ensure Outdoor Unit is Unobstructed – Keep the area around your outdoor unit free of leaves, dirt, and debris to maintain proper airflow. Feeling convinced?
