How Much Cooling Does a Home Need in Washington?
In the mild but increasingly warm summers of Northwestern Washington, it’s important to choose a cooling system that meets your home’s specific needs. Too small, and your system will struggle to keep up. Too large, and you’ll waste energy and sacrifice comfort. At Barron Heating AC Electrical & Plumbing, we use professional heat load calculations to ensure your air conditioning system is sized perfectly for your space.
A heat load calculation is a detailed analysis that takes into account your home’s square footage, insulation, window placement, sun exposure, air leakage, number of occupants, and internal heat sources. This data helps us determine the precise amount of cooling, measured in BTUs (British Thermal Units)—your home needs to maintain consistent, comfortable indoor temperatures.
In Washington, a common temperature differential (the difference between the desired indoor temperature and the outdoor temperature) is usually between 20-25°F during peak summer conditions. For example, if the outside temperature is 85°F, your AC system should be able to maintain an indoor temperature around 60-65°F (which is usually too cold for most people), depending on the system’s capacity and your home’s performance. An undersized system may not be able to maintain this differential, while an oversized one may cycle on and off too frequently, leading to inefficient operation and excess wear.
That’s why we take a WholeHome™ approach. We don’t just install air conditioners—we evaluate your entire home’s energy performance to ensure your cooling system works efficiently and effectively. Our NATE-certified Home Performance Experts consider everything from your ductwork and ventilation to insulation and air sealing to help you achieve optimal results.
By investing in a properly sized system, you not only increase comfort but also reduce energy waste, lower your monthly utility bills, and extend the life of your equipment. With us, you can trust that your cooling solution is built around your home, not a one-size-fits-all guess.

You Have Several Options for Home Cooling
When it comes to keeping your home comfortable during the warmer months in Bellingham and Northwestern Washington, you have several high-quality options. At Barron Heating AC Electrical & Plumbing, we take a WholeHome™ approach to help you choose the right cooling system based on your home’s layout, your comfort goals, and your energy efficiency priorities.
Central Air Conditioning
Central AC systems are a great solution for homes with existing ductwork. These systems distribute cool air evenly throughout your home and are known for their powerful, consistent performance. Modern central air conditioners feature high SEER2 (Seasonal Energy Efficiency Ratio 2) ratings, variable-speed motors, and smart thermostat compatibility, delivering dependable comfort and lower energy costs.
Ductless Mini-Split Systems
Ductless systems offer flexibility, energy efficiency, and precise control over individual rooms. They’re perfect for homes without ductwork, renovations, or areas that need supplemental cooling. With an outdoor condenser connected to one or more indoor air handlers, you can enjoy zoned cooling and reduced energy waste.
Heat Pumps
Heat pumps are one of the most versatile and efficient options available. They provide both heating and cooling by transferring heat rather than generating it, making them ideal for Washington’s mild climate. Whether you choose a traditional air-source unit or a ductless heat pump, these systems offer year-round comfort and significant energy savings.
High-Efficiency Systems
We proudly offer high-efficiency cooling solutions, including top-tier Daikin systems. These advanced units are engineered for maximum performance and minimal energy use. From variable-speed compressors to integrated smart technology, high-efficiency systems help you save money while enjoying a more comfortable indoor environment.
No matter your home’s size or setup, we have the knowledge and expertise to match you with the ideal cooling solution. Our NATE-certified technicians and Home Performance Experts ensure every system is properly sized and installed for optimal comfort and long-term reliability.

What to Do If Your AC Fails Abruptly

An unexpected air conditioning failure in the middle of a warm day can leave you feeling frustrated and uncomfortable, especially during a heatwave. We understand how stressful an AC breakdown can be, and we’re here to help homeowners throughout Bellingham and Northwestern Washington respond quickly and effectively.
If your AC stops working without warning, follow these steps before calling for professional service:
- Check the Thermostat: Make sure it’s set to "cool" and the temperature is set lower than the current room temperature. Sometimes, a simple setting adjustment is all that’s needed.
- Inspect the Circuit Breaker: A tripped breaker can shut down your air conditioner. Locate your electrical panel and reset any tripped breakers, especially those labeled for the AC or HVAC system.
- Check the Air Filter: A clogged or dirty air filter can block airflow and cause your system to shut down. Replacing a dirty filter may restore function and improve efficiency.
- Examine the Outdoor Unit: Look for signs of damage, debris, or blocked airflow. Clear away leaves, dirt, or obstructions, and make sure the unit has at least two feet of clearance on all sides.
- Listen and Observe: Note any unusual sounds, odors, or behavior from the system. This information will help our technicians diagnose the issue more quickly.
If these steps don’t resolve the issue, it’s time to call in the experts. Our NATE-certified Home Performance Experts respond promptly to AC emergencies and work quickly to restore your cooling system. We service all makes and models and bring a WholeHome™ mindset to every repair, ensuring your system is not only fixed but operating at its highest potential.
We also offer preventative maintenance services to help reduce the risk of sudden breakdowns in the future. Your comfort and peace of mind are our top priorities, and we’re committed to helping you stay cool when it matters most.

Tips for Lowering Your Summer Heating Costs
While heating may not be top of mind during summer, some households in Bellingham and Northwestern Washington still rely on heating systems in the cooler mornings or in homes with damp basements and shaded areas. We help homeowners manage their year-round comfort needs, and that includes keeping heating costs in check during the warmer months.
Here are a few tips to help you reduce unnecessary heating expenses this summer:
Adjust Your Thermostat Settings
Set your thermostat to a comfortable but energy-conscious temperature. In summer, reduce or turn off heating zones you’re not actively using. If you have a programmable or smart thermostat, create schedules that limit heating during the day when it’s warmer or when no one is home.
Seal Air Leaks and Insulate
Cracks around windows, doors, and ductwork can allow warm air to escape and cool outdoor air to seep in—making your system work harder than necessary. Sealing gaps and upgrading insulation, especially in crawlspaces and basements, can reduce energy waste and boost efficiency.
Use Natural Ventilation and Sunlight
Open windows during the day to bring in fresh air and let natural sunlight warm cool spots in your home. Just remember to close windows and blinds at night to retain any warmth gained during the day.
Schedule Maintenance
Even if your heating system isn’t in heavy use, summer is a great time for a tune-up. Our NATE-certified technicians at Barron Heating AC Electrical & Plumbing can inspect and clean your equipment to ensure it’s ready for the next cold season, while optimizing performance in the meantime.
Upgrade to a High-Efficiency System
If your heating system is outdated, it may be using more energy than necessary—even in minimal operation. Upgrading to a modern, high-efficiency unit, such as a variable-speed heat pump, can cut costs and improve year-round performance.
Our WholeHome™ approach ensures you get the best combination of comfort and energy savings—no matter the season.
