How to Protect an AC Unit Near the Ocean

Living near the ocean has its perks—but it can take a toll on your air conditioning system. Salt air, humidity, and sand can corrode metal components and shorten the lifespan of your outdoor unit. If you’re in a coastal area like White Rock, Tsawwassen, or other parts of the Lower Mainland near the sea, protecting your AC unit is a smart investment in long-term efficiency and performance.

Why Coastal Environments Are Tough on AC Units

Salt-laden air accelerates corrosion, especially on condenser coils and external housing. Moisture from ocean breezes can cause rust and electrical issues, while airborne sand and debris can clog fins and restrict airflow.

Top Ways to Protect Your Outdoor AC Unit Near the Coast

1. Apply a Protective Coating

Ask your HVAC technician about coil coatings designed to resist salt corrosion. Anti-corrosion sprays or epoxy coatings can help extend the life of your outdoor unit.

2. Use a Coastal-Rated AC Unit

If you’re installing a new system, choose one with a coastal durability rating. These models are specifically designed to handle salty air and humid conditions.

3. Rinse the Unit Regularly

Hose down the outdoor unit with fresh water every 2–4 weeks to remove salt buildup, especially during summer months. Do not use a pressure washer—it can damage delicate components.

4. Install a Wind Barrier

A non-obstructive barrier or fence can help block direct exposure to salty wind and sand without limiting airflow. Just make sure there’s enough clearance for proper ventilation.

5. Elevate the Unit

Installing the unit on a raised platform helps avoid contact with salty ground water or sand during storms or high tides.

6. Schedule Preventive Maintenance

Coastal units need more frequent inspections. Have an HVAC pro check your unit at least once a year (twice if possible) to clean coils, check connections, and inspect for early signs of corrosion or wear.

Bonus Tips for Long-Term Protection

Consider a weatherproof AC cover for the off-season (but never while running).
Trim back shrubs and plants to keep salty moisture and debris at bay.
Record your unit’s serial number and warranty in case of salt-related failure.

Frequently Asked Questions About Coastal AC Units

How often should I rinse my AC unit if I live near the ocean?

Every 2–4 weeks in the summer and after any major windstorm or salt spray event.

What’s the best AC unit for coastal environments?

Choose a unit with a factory-applied coil coating and a marine-grade rating if available. Brands like Trane and Daikin offer coastal models.

Can I install the AC unit indoors to protect it?

No. Outdoor AC condensers require external airflow and heat dissipation. Protect it using barriers, coatings, and elevated mounts instead.

4. Full System Evaluation

If your system is 10+ years old, the technician may recommend evaluating whether a full unit replacement makes more financial sense—especially if efficiency is poor or rebates apply.

How to Prepare for Compressor Service

Clear debris and trim vegetation around the outdoor unit for technician access.
Turn off the system at the thermostat and breaker before service if instructed.
Keep pets indoors and ensure someone 18+ is home to approve any repair decisions.
Ask about warranty status—some compressor parts may be covered for up to 10 years.

Repair or Replace? Making the Right Call

If your compressor is still under warranty and your system is in good shape, repair may be your best option. But if the unit is aging or you’re facing repeated issues, replacement could be more cost-effective—especially with rebates available in BC for high-efficiency systems.

Ask your HVAC technician for a comparison of repair vs. replacement costs and long-term savings. Rebates through CleanBC Better Homes and FortisBC may help offset upgrade costs.

Frequently Asked Questions About AC Compressor Repair

Can a compressor be repaired or only replaced?

In some cases, damaged components like valves or wiring can be repaired. But if the compressor motor fails, replacement is usually required.

How long should an AC compressor last?

Most compressors last 10–15 years with regular maintenance, though poor installation or overheating can shorten their lifespan.

Will I need to replace refrigerant too?

Yes—if your system uses outdated R-22 refrigerant, it may require a full retrofit or replacement with a modern R-410A system.

Troubleshooting Common Issues with SEER Rating in Air Conditioning Systems

When evaluating air conditioners, the SEER rating (Seasonal Energy Efficiency Ratio) is often front and centre. But while it’s meant to be a simple measure of efficiency, homeowners often encounter confusion or unexpected issues when SEER ratings don’t match real-world performance.

In this guide, we’ll cover common SEER-related issues, how to troubleshoot them, and what factors can impact your air conditioner’s true efficiency.

What is a SEER Rating?

The SEER rating measures the cooling output of an air conditioner over a typical cooling season divided by the total electric energy input. Simply put, it indicates how energy-efficient an AC unit is under standardized conditions. Higher SEER ratings mean greater efficiency.

In Canada, modern air conditioners typically range from SEER 13 to SEER 21+, with rebates and incentives often available for high-efficiency models.

Common SEER Rating Issues Homeowners Face

1. SEER Rating Doesn’t Match Utility Bills

Many homeowners expect immediate savings after upgrading to a high-SEER unit, but see little change in their energy bills. Causes include:

Leaky or poorly insulated ductwork
Inaccurate thermostat calibration
Poor home insulation or air leaks
Oversized or undersized AC units

2. Mismatch Between Indoor and Outdoor Units

A high-SEER outdoor condenser paired with an older, less efficient indoor evaporator coil will not perform as advertised. Always ensure both components are compatible and matched in SEER rating.

3. Real-World Performance Differs from Lab Ratings

SEER ratings are calculated under controlled lab conditions. Factors like BC’s variable climate, humidity, home layout, and installation quality all affect real-world performance.

4. Misleading Marketing Claims

Some manufacturers or installers may promote \”up to SEER 21\” ratings, which reflect ideal conditions. Actual performance may be lower, especially in older homes with energy inefficiencies.

How to Troubleshoot SEER Performance Issues

1. Conduct a Home Energy Audit

An energy audit identifies insulation gaps, air leaks, and ductwork issues that reduce your system’s efficiency despite a high SEER rating.

2. Verify Proper Installation

Poor installation is one of the biggest causes of SEER underperformance. Ensure your unit is sized correctly, installed level, and that refrigerant levels are within manufacturer specifications.

3. Maintain Regular HVAC Service

Dirty coils, clogged filters, and low refrigerant can all reduce efficiency. Schedule annual maintenance to keep your AC performing to its rated SEER level.

4. Optimize Thermostat Settings

Using programmable or smart thermostats helps regulate temperatures more efficiently, maximizing your SEER-rated unit’s performance.

Are High SEER Units Worth It?

High-SEER air conditioners can offer substantial long-term savings, but only if your home’s infrastructure supports that efficiency. Upfront costs are higher, but rebates through programs like CleanBC Better Homes and FortisBC can offset installation expenses.

In British Columbia, where energy efficiency incentives are strong, high-SEER systems are often a worthwhile investment—especially in newer or upgraded homes.

Common Questions About SEER Ratings and Air Conditioning

What SEER rating should I look for in BC?

Most experts recommend SEER 16 or higher for homes in British Columbia, balancing efficiency with cost. Higher SEER units may qualify for rebates.

Does SEER rating affect heating performance?

SEER only measures cooling efficiency. For heating, look at the HSPF (Heating Seasonal Performance Factor) rating, especially with heat pumps.

Can maintenance improve SEER performance?

Yes. Regular maintenance like coil cleaning, filter replacement, and refrigerant checks can help your system perform closer to its rated SEER level.

Is SEER the only factor in AC efficiency?

No. Ductwork condition, home insulation, local climate, and installation quality all impact actual energy use and comfort levels.

Questions to Ask About Heating & Cooling When Purchasing a Home

Shopping for a new home is exciting—but don’t let beautiful countertops or curb appeal distract you from what’s going on behind the walls. Your potential new home’s heating and cooling systems (HVAC) play a huge role in both comfort and long-term costs. If you overlook them during the buying process, you could be in for unexpected repairs, poor efficiency, or a system that doesn’t suit your needs. Whether you’re a first-time buyer or moving into your next place, here are the most important heating and cooling questions to ask before making an offer.

1. What Type of HVAC System Is Installed?

Start with the basics. Is the home heated with a furnace, boiler, heat pump, or electric baseboard? Does it have central air conditioning, a ductless mini-split, or no cooling system at all? Knowing the system type gives you a sense of how the home is heated and cooled, what maintenance it requires, and whether it’s compatible with future upgrades (like switching to a heat pump).

2. How Old Is the Equipment?

HVAC systems have a lifespan. Furnaces and air conditioners typically last 10–15 years, while heat pumps can last up to 20 with proper care. Ask for installation records and see if any components have been replaced or upgraded. An older system isn’t necessarily a deal-breaker—but it may mean repair or replacement costs are coming soon.

3. What’s the Home’s Energy Efficiency Like?

Look beyond the appliances themselves—how energy-efficient is the home overall? Ask about:

Insulation levels in the attic and walls
Window type (single-pane vs. double-pane)
Drafts or cold spots
Monthly energy bills (ask for a 12-month average if possible)

This can give you insight into how hard the HVAC system has to work—and how much it might cost you to run it.

4. Are There Any Known Issues with the Heating or Cooling?

It’s important to ask the seller directly if there are any known problems—strange noises, uneven temperatures, persistent maintenance issues. Even if everything seems fine during a walkthrough, you could uncover problems with a simple question. Also: look at the vents. Are they dusty or blocked? Is airflow consistent in each room? Trust your senses.

5. Has the HVAC System Been Regularly Maintained?

Well-maintained systems last longer and perform more efficiently. Ask if the homeowner has kept up with routine maintenance like:

Annual furnace/boiler servicing
Air filter replacements
Air conditioner or heat pump inspections
Duct cleaning (if applicable)

Bonus if they have records from a professional HVAC company.

6. What’s the Heat Source?

Is the home heated with natural gas, electricity, propane, or oil? This makes a big difference in operating costs—especially in British Columbia, where switching from gas to electric heat pumps can qualify for rebates. If the home still runs on oil or propane, you may want to factor in conversion costs down the road.

7. Is the HVAC System Covered Under Warranty?

Some systems (especially newer ones) may still be under manufacturer or extended warranty. This could save you a lot of money on unexpected breakdowns. Ask for paperwork. If the system was professionally installed, the installer’s name and date should be listed.

8. Is the HVAC System Sized Correctly for the Home?

This is something your home inspector or an HVAC professional should verify. An oversized or undersized system won’t run efficiently and may leave parts of your home too hot or too cold. It can also shorten the equipment’s lifespan.

9. Could I Be Eligible for Rebates If I Upgrade?

If you’re thinking of switching to a heat pump or upgrading to a more energy-efficient system, check out rebate options through:

These programs offer thousands in savings for switching from fossil fuels to high-efficiency electric systems.

Frequently Asked Questions

Heat Pumps vs. Air Conditioners – Which HVAC System Is Best for BC Homes?

Heat Pumps vs. Air Conditioners: Which is Better for Year-Round Comfort?

If you’re looking to upgrade your home’s HVAC system, you’ve likely come across two main options: a heat pump or a central air conditioner. At first glance, they may seem similar—they both cool your home in the summer—but there’s more to the story. One can also heat your home. In this guide, we’ll compare the two systems and help you decide which is better for year-round comfort based on how they work, their energy efficiency, costs, and how well they perform in British Columbia’s climate.

What’s the Difference Between a Heat Pump and an Air Conditioner?

Air Conditioners are designed for one thing: cooling. They extract heat from inside your home and release it outdoors. They rely on a furnace or other heat source to provide warmth in the winter. Heat Pumps, on the other hand, can both cool and heat. In the summer, they work just like an air conditioner. In the winter, they reverse direction and pull heat from the outdoor air to warm your home. Modern heat pumps can do this efficiently even in colder temperatures, making them a strong contender for BC homeowners.

Energy Efficiency

Heat pumps tend to be more energy-efficient year-round, especially in regions with moderate winters like the Lower Mainland. That’s because they transfer heat instead of generating it, using less electricity than electric baseboard heaters or a furnace with standard AC. If you only need cooling, a high-efficiency air conditioner can still be an effective choice—but you’ll also need to factor in the efficiency of your heating system. British Columbia Efficiency Tip: Consider pairing a heat pump with your existing furnace in a dual-fuel system. This lets the heat pump handle most of the heating and cooling, while the furnace kicks in only when temperatures drop below a certain point.

Installation and Cost

Upfront Costs: Heat pumps generally cost more to install than air conditioners, especially if they’re replacing a cooling-only setup.
Long-Term Savings: Because heat pumps offer both heating and cooling, you may save money over time—especially when you factor in available rebates.

BC Rebates Available:

Up to $10,000 in rebates through the CleanBC Better Homes program for switching to an eligible heat pump or dual fuel system.
FortisBC also offers rebates when upgrading from fossil-fuel systems to electric or dual fuel heat pump systems.

Climate Considerations in BC

In the Lower Mainland, heat pumps are often the more practical choice. Winters are typically mild enough for a heat pump to provide reliable warmth without needing a backup system. In colder interior regions, you might want to pair a heat pump with a furnace for optimal performance during freezing temperatures. Many BC homes now use dual-fuel setups to get the best of both worlds.

Which Should You Choose?

Choose a heat pump if you want:

One system that heats and cools
Long-term energy savings
Access to provincial rebates
A more sustainable, all-electric home

Choose an air conditioner if you:

Already have an efficient heating system
Only need cooling
Want a lower upfront cost

Still unsure? The best system depends on your home size, layout, insulation, and your comfort preferences. A qualified HVAC professional can evaluate your home and recommend a system tailored to your needs.

Understanding Flow Rates in Tankless Water Heaters

When upgrading to a tankless water heater, one of the most important factors to consider is flow rate. Unlike traditional water heaters, which store a set amount of hot water, tankless systems heat water on demand. This means that the flow rate directly impacts how much hot water you can use at one time. If your unit’s flow rate isn’t high enough, you may run into issues like lukewarm water when multiple fixtures are in use.

Let’s break down what flow rate is, how it affects your tankless water heater, and what you need to know to get the right system for your home.

What Is Flow Rate?

Flow rate refers to the amount of water moving through your tankless water heater, measured in gallons per minute (GPM). The higher the flow rate, the more hot water your system can provide at once. Each fixture in your home has a different flow rate:

Shower: ~2.5 GPM
Kitchen Sink: ~1.5 GPM
Bathroom Faucet: ~1.0 GPM
Dishwasher: ~1.5 GPM
Washing Machine: ~2.0 GPM

If you’re using multiple fixtures at the same time, your water heater needs to meet the total demand. For example, if you’re running a shower and a dishwasher simultaneously, you’ll need at least 4 GPM to maintain a steady hot water supply.

Why Flow Rate Matters in a Tankless System

Unlike traditional water heaters, which have a storage tank, tankless water heaters must instantly heat water as it flows through the system. If your unit isn’t powerful enough, you may experience:

Inconsistent water temperatures – Hot water may turn lukewarm when multiple fixtures are in use.
Lower water pressure – A heater with insufficient flow rate may struggle to provide adequate pressure.
Reduced energy efficiency – An overworked system may consume more energy, leading to higher utility bills.

Choosing the Right Tankless Water Heater for Your Home

To ensure you get the right system, follow these steps:

Calculate Your Home’s Peak Demand: Add up the flow rates of all fixtures you expect to use simultaneously. This will determine the minimum GPM rating you need.
Consider the Incoming Water Temperature: In the winter months in British Columbia, incoming water is colder and takes more energy to heat. This can reduce the heater’s effective GPM output, therefor you should choose a higher-capacity unit to compensate for this.

Match the Heater’s Capacity to Your Needs :Standard homes typically require 6–8 GPM for comfortable use, while larger households may need 10+ GPM.

Ways to Improve Flow Rate & Hot Water Performance

Install a Secondary Tankless Heater: Large homes may benefit from a second unit for extra capacity.
Upgrade Your Pipes: Narrow pipes can restrict water flow, affecting pressure and temperature.
Use Low-Flow Fixtures: Reducing water demand helps maximize efficiency without sacrificing comfort.

Tankless Water Heater Rebates in British Columbia

If you’re upgrading to an energy-efficient tankless water heater, you may be eligible for rebates and incentives in BC:

FortisBC Natural Gas Water Heater Rebates – Up to $3,000 for income-qualified homeowners switching to an energy-efficient tankless system. (Learn more)
CleanBC Better Homes Program – Rebates of up to $3,500 for upgrading to a heat pump water heater. (Learn more)
BC Hydro Rebates – Financial incentives for installing high-efficiency water heating systems. (Learn more)

Taking advantage of these programs can help offset installation costs while lowering your energy bills.

Choosing the Right Tankless Water Heater

Understanding flow rates is key to getting the most out of your tankless water heater. Choosing the right unit ensures consistent hot water, better energy efficiency, and long-term savings.

Use a humidifier to increase moisture levels or a dehumidifier to eliminate excess humidity. Running your AC and exhaust fans also helps regulate indoor moisture levels.

Set Up Air Purifiers

Air purifiers help remove allergens, microbes, and pollutants, making them an excellent investment for pet owners. Place them in areas where pets spend most of their time to maximize effectiveness.

For a whole-home solution, consider installing a whole-house air purifier connected to your HVAC system. These systems help remove airborne contaminants throughout your entire home.

Run Your Central AC

Your air conditioner helps circulate and filter air, improving IAQ. Even when temperatures are mild, use the “fan” setting to keep air moving and reduce airborne pollutants. Your AC also helps maintain optimal humidity levels.

Change Air Filters Regularly

HVAC filters trap dust, pet dander, and other particles, but when they become dirty, they lose efficiency and can lower air quality. Check and replace filters frequently, especially in homes with pets.

Vacuum and Dust Frequently

Pet fur, dander, and dust accumulate quickly, contributing to poor IAQ. Vacuuming and dusting regularly can reduce allergens and pollutants. Use a vacuum with a HEPA filter for best results.

Open (or Close) the Windows as Needed

Letting fresh air circulate can improve IAQ, but it depends on outdoor conditions. Open windows when the air outside is clean, but keep them closed during high pollen seasons or when air pollution levels are high.

Get Professional HVAC Maintenance

Routine HVAC maintenance ensures your system runs efficiently, helping control humidity and improving IAQ. A professional technician will:

Inspect components and replace parts as needed
Check for early signs of damage
Clean the HVAC unit to prevent dust buildup and maintain optimal airflow
