How often do I need an HVAC system tune-up in Boise?

We recommend having your HVAC system serviced twice a year in Boise. Tune-ups help improve energy efficiency, reduce wear and tear, and catch minor issues before they become costly problems.

How often should I change my filter?

Changing (or replacing) your filter depends on the environment you’re in and how busy your household is. Changing your 5-inch filter on schedule helps improve indoor air quality, reduce strain on your system, and lower energy costs.

What are the common signs that I need HVAC repair in Boise?

If your furnace, air conditioner, heat pump, or ductless system is making strange noises, producing uneven temps, cycling on and off too often, or driving up your energy bills, it may be time for a repair. Residents in Boise, Caldwell, Kuna, and nearby areas trust Western Heating & Air Conditioning to diagnose and fix HVAC issues fast—before a minor problem becomes a costly breakdown.

How long does an HVAC system typically last in Idaho homes? When should I replace my HVAC in Boise?

Most furnaces and air conditioners last 12 to 16 years in Idaho, depending on how well they’re maintained and how often they’re used. Regular tune-ups and timely repairs can extend your system’s life. 

If your HVAC is 12+ years old and requires frequent repairs or struggles to heat or cool your home evenly, it may be time to consider a replacement. We offer free quotes and expert recommendations to help you find the right system for your budget and comfort.

What size HVAC unit do I need for my Boise home?

HVAC size depends on several factors—like your home’s square footage, ceiling height, insulation, and window placement. Our HVAC experts in Boise perform detailed heat load calculations to recommend the properly sized furnace for maximum comfort and efficiency.

What does AFUE mean?

AFUE stands for Annual Fuel Utilization Efficiency—a measure of how efficiently your furnace converts fuel into heat. For example, a furnace with a 90% AFUE rating turns 90% of its fuel into usable heat. Higher AFUE = greater efficiency and lower utility bills.

What does SEER2 mean?

SEER2 stands for Seasonal Energy Efficiency Ratio 2. It’s a newer standard for measuring the energy efficiency of air conditioning and heat pump systems

How can I save on my heating and cooling bill?

Try these tips to lower your energy costs:

• Replace or clean air filters regularly
• Upgrade to a smart or programmable thermostat
• Keep sun-facing windows covered during summer and open during winter
• Seal gaps around doors and windows
• Improve insulation in attics or crawlspaces
• Schedule regular HVAC tune-ups with Western Heating & Air Conditioning
• Consider upgrading to a newer, ENERGY STAR® rated model

Why is my heater blowing cold air?

If your heater is pushing out cold air, it could be due to:

• The thermostat fan setting is on, which continually circulates air, even when it’s not being warmed, making it feel like cool air is blowing.
• The system hasn’t had time to warm up, especially after being off for a period. During this short time, the system is igniting the burners and heating the heat exchanger.
• A dirty or clogged air filter can limit airflow through your system, which may cause the heater to overheat and shut off the burners as a safety precaution. When that happens, the blower may continue running, pushing unheated air through the vents.
• If the igniter is dirty, worn out, or faulty, your heater may fail to light the burners—even though the blower fan continues to run.

Our team can perform a thorough heater inspection to quickly identify the issue and restore warm air to your home.

Why is my AC blowing warm air?

A few common culprits of warm air from your AC include:

• A dirty air filter can restrict airflow through your system, making it harder for the AC to circulate cool air throughout your home. 
• If your system is low on refrigerant (usually due to a leak), it can’t cool the air properly—it’s what absorbs heat from your indoor air and releases it outside.
• Frost buildup on coils can occur when airflow is reduced. This causes the system to blow warm air or stop working altogether.
• Dirty coils block heat exchange, which means your system can't remove heat from your home effectively. As a result, your AC might blow air that feels warm or humid.
• If your thermostat isn’t working correctly, it may be misreading your home’s temperature or sending the wrong signals to your AC unit. 

If your AC isn’t cooling as it should, call Western Heating & Air Conditioning. We’ll get your home comfortable again in no time.

Do I need to cover my outdoor AC unit in winter?

Your outdoor unit is built to handle Boise’s winter weather. No cover is necessary if utilizing a heat pump. The unit should be raised above snow level and protected from roof run off as it operates in winter. Avoid plastic tarps, which can trap moisture and cause damage.

Why is my air conditioner freezing up?

If your AC is forming ice or frost, it could be due to:

• A dirty filter is blocking airflow
• Low refrigerant levels
• Malfunctioning components
• Problems with the blower motor or coil

Turn off your system and contact Western Heating & Air Conditioning to avoid long-term damage.

What is a heat pump, and how does it work?

A heat pump is an all-in-one heating and cooling system that works by moving heat, rather than generating it. In the winter, it extracts heat from the outdoor air and transfers it inside to warm your home. In the summer, it reverses the process, removing heat from your home and releasing it outdoors to keep you cool. This makes heat pumps especially energy-efficient and environmentally friendly.

Can a heat pump replace my furnace and air conditioner?

Yes—heat pumps are designed to handle both heating and cooling. Many homeowners in the Treasure Valley use a heat pump as their primary HVAC system. For colder regions or older homes with higher heat loss, we can also install a dual-fuel system, which pairs your heat pump with a gas furnace for backup heating when temperatures drop significantly.

Do heat pumps work in Idaho’s cold weather?

Yes! Modern cold-climate heat pumps are designed to perform efficiently even when temperatures dip below freezing. While traditional heat pumps used to struggle in cold weather, today’s models can provide reliable heating in most Idaho winters. For especially frigid nights, we may recommend pairing your heat pump with a backup heat source for extra peace of mind.

What is a ductless mini split system, and how does it work?

A ductless mini split is a compact, energy-efficient heating and cooling solution that doesn’t rely on ductwork. Instead, it uses an indoor air handler connected to an outdoor compressor via refrigerant lines. The system transfers heat between the indoor and outdoor units—cooling your space in summer and warming it in winter. It’s perfect for single rooms, additions, or areas without duct access, offering zoned temperature control without the bulk of traditional HVAC systems.

Do ductless mini splits require regular maintenance?

Yes, regular upkeep is key to performance and longevity. You should:

• Clean the reusable filters every month.
• Keep the indoor and outdoor units free of dust and debris.
• Schedule a professional tune-up twice a year to check refrigerant levels, clean coils, inspect wiring, and ensure proper operation.

Need service? Western Heating & Air Conditioning offers convenient ductless mini split maintenance throughout Treasure Valley.

What IAQ services does Western Heating & Air Conditioning provide in Boise and surrounding areas?

We offer a full range of indoor air quality solutions across Boise, Eagle, Star, Emmett, and nearby areas, including:

• 5-inch air cabinets
• Duct cleaning and sanitizing
• Air scrubber, ionizer, and UV light installation
• Whole-home air filtration and HEPA systems
• Humidifiers and dehumidifiers

Whether you need to combat seasonal allergies, improve your home’s ventilation, or install high-efficiency filtration, Western Heating & Air Conditioning has the tools and experience to help you breathe easier.

What affects indoor air quality in Boise-area homes?

Many everyday elements can impact the air you breathe indoors, including:

• Dust, pet dander, and pollen
• Humidity levels (too dry or too moist)
• Nearby construction
• Mold and mildew growth
• Tobacco smoke or cooking fumes
• Wildfires
• Off-gassing from cleaning products and furniture
• Gas appliances and fireplaces
• Clogged filters or dirty ductwork

In homes across Boise, Meridian, Nampa, and Caldwell, a combination of outdoor pollution, older construction, and tightly sealed windows can trap these contaminants indoors.

How do I know if my indoor air quality needs help?

Here are some common signs your IAQ may need attention:

• Persistent dust even after cleaning
• Lingering odors that don’t go away
• Worsening allergies or sinus issues
• Dry skin, itchy eyes, or headaches
• Excess humidity or static electricity

If any of these sound familiar, contact Western Heating & Air Conditioning or try our IAQ Quiz to find the right solution for your home.

How does my heating/cooling system affect my IAQ?

Your HVAC system plays a major role in circulating and filtering the air you breathe. If it’s not properly maintained, it can spread dust, allergens, and even mold spores throughout your home.

Poor IAQ can result from:

• Dirty or clogged filters
• Leaky or unclean ductwork
• Inadequate ventilation
• Improper humidity control

At Western Heating & Air Conditioning, we offer IAQ add-ons that work with your HVAC system—like advanced filtration, UV purification, and humidity control—to improve the quality of your air while keeping your home comfortable.

General Electrical FAQs

What electrical services does Western Heating & Air Conditioning provide in Boise and the surrounding areas?

Western Heating & Air Conditioning offers expert electrical services across Boise, Garden City, Nampa, Kuna, Meridian, and surrounding areas. Our licensed electricians handle everything from installing ceiling fans, outlets, indoor/outdoor lighting, and generators to electrical panel upgrades, whole-home rewiring, and surge protection. Whether you need a simple fixture swap or a complete electrical system overhaul, we’re the team to call.

Do you offer emergency electrical services?

Yes! Western Heating & Air Conditioning provides emergency electrical services for everything from panel failures to faulty wiring. If something goes wrong, give us a call. We’re here when you need us most in Boise and surrounding areas.

Do I need a permit for electrical work in my home?

Yes—most electrical projects in Idaho require a permit, especially if you're adding new wiring, upgrading your service panel, or installing circuits for appliances like hot tubs or EV chargers. At Western Heating & Air Conditioning, we handle the permitting and inspection process to ensure your project meets local Boise-area codes and safety standards.

Is it safe to do my own electrical work?

DIY electrical work might seem simple, but even basic tasks, like outlet swaps or fan installs, can be risky if done improperly. Incorrect wiring can lead to electrical fires, shock hazards, or failed inspections. Western Heating & Air Conditioning always recommends hiring a licensed electrician—it’s the safest, fastest, and most code-compliant way to get the job done right.

What are the signs of electrical problems in a home?

Look out for:

• Flickering or dimming lights
• Burning smells near outlets or switches
• Buzzing sounds from the panel
• Warm or discolored outlets
• Frequently tripped breakers or blown fuses

If you notice any of these issues in your home—from Boise to Eagle—call Western Heating & Air Conditioning for a professional inspection.

How often should I have my home’s electrical system inspected?

An electrical inspection every 3–5 years is a good rule of thumb—sooner if your home is 30+ years old, you’re planning a remodel, or you’ve recently moved in. Western Heating & Air Conditioning provides comprehensive inspections for homes throughout Boise, Meridian, Nampa, and nearby cities.

Can I install a ceiling fan where a light fixture was?

Yes, in many cases, you can replace a light fixture with a ceiling fan. However, the electrical box must be fan-rated to support the weight and movement. Western Heating & Air Conditioning can inspect the setup and safely install your new ceiling fan.

How do I know if my home needs rewiring?

Common signs include flickering lights, tripped breakers, burning smells, or outlets that feel warm. Homes over 40 years old are especially likely to need partial or full rewiring. Schedule an inspection with Western Heating & Air Conditioning to find out for sure.

Can you rewire part of a home without tearing out all the walls?

Yes, we often rewire using minimal intrusion techniques like fishing wires through existing cavities. Western Heating & Air Conditioning works efficiently to preserve your home’s structure while upgrading its electrical safety.

How long does a whole-home rewiring project take?

Most rewiring jobs take 3 to 10 days, depending on home size and accessibility. We’ll provide a clear timeline and keep disruptions to a minimum.

When should I upgrade my electrical panel?

If your electrical panel is over 25 years old, breakers trip frequently, or you're adding high-demand systems like EV chargers or HVAC equipment, you may need an upgrade. Western Heating & Air Conditioning offers panel upgrades tailored to modern needs.

What’s the difference between a fuse box and a circuit breaker?

Both protect your circuits from overloads. Circuit breakers are resettable switches commonly found in modern homes. Fuses, often seen in older panels, need to be replaced when blown. Western Heating & Air Conditioning can help you upgrade outdated fuse boxes to safer, more convenient breaker panels. 

What’s a GFCI outlet, and where is it required?

GFCI (Ground Fault Circuit Interrupter) outlets shut off power immediately if they detect a shock hazard. Modern code requires them in areas with water, such as bathrooms, kitchens, garages, laundry rooms, basements, and outdoors, though older homes may not have them since they were built to the code at the time. 

If you’re unsure your Boise-area home is fully protected, we can inspect and upgrade your outlets as needed.

What does whole-home surge protection do?

It safeguards your entire home from power surges caused by lightning strikes, grid issues, or internal surges from large appliances. These devices protect sensitive electronics and HVAC systems from permanent damage. 

Our licensed electricians professionally install whole-home surge protection at the electrical panel to guard your home against voltage spikes.

Do I need surge protection if I already use power strips?

Power strips offer minimal protection at a single outlet. Whole-home surge protection defends every circuit in your home, giving you broader and more reliable coverage.

Do you offer emergency plumbing services?

Yes! Western Heating & Air Conditioning provides emergency plumbing services in Boise and surrounding areas for everything from burst pipes to major leaks and water heater breakdowns. If something goes wrong, give us a call. 

Do I need plumbing maintenance?

Annual plumbing inspections are a smart way to catch minor issues before they become expensive problems—especially in older homes or before buying/selling a house. 

Western Heating & Air Conditioning offers maintenance services designed to extend the life of your plumbing and keep everything flowing smoothly.

Why is my water pressure so low?

Low water pressure can stem from:

• Pipe corrosion or buildup
• A partially closed shut-off valve
• A broken pressure regulator
• Leaks in the plumbing system
• Clogs in the pipes or fixtures

Our plumbers will diagnose the exact cause and get your water pressure back to normal.

Can I upgrade plumbing fixtures myself?

Some small upgrades, like replacing a showerhead or faucet handle, are DIY-friendly. But anything involving pipes, shut-off valves, or drainage should be left to a licensed and insured plumber like Western Heating & Air Conditioning. We can help install new sinks, toilets, faucets, or fixtures quickly and safely.

Should I use chemical drain cleaners to fix a clog?

Chemical cleaners can damage pipes over time and are not always effective. For stubborn or recurring clogs, it’s best to call a professional.

How do I know if I have a hidden water leak?

Common signs of hidden leaks include:

• A sudden spike in your water bill
• Damp spots or warping on floors or walls
• Musty smells, mold, or mildew
• Low water pressure
• The sound of running water when everything is turned off

What should I do if my pipes freeze in winter? How do I prevent it?

First, turn off your home’s main water shut-off valve. If possible and safe, also switch off the electricity to the affected area. Then call Western Heating & Air Conditioning right away. Our emergency response team serves Boise and surrounding cities and will arrive quickly to stop the leak and minimize water damage.

To prevent this issue from happening, keep your thermostat set to at least 55°F, even if you’re away from home. Open cabinet doors to let warm air circulate around plumbing, and consider pipe insulation for unheated areas like basements, attics, garages, and exterior spigots.

How long do water heaters typically last?
When should I replace my water heater?

Most tank-style water heaters last 8–12 years. Tankless water heaters generally last longer—up to 20 years—and Western Heating & Air Conditioning installs and services both types across the Treasure Valley. 

Consider replacing yours if you notice:

• Rust-colored or smelly water
• Rumbling or banging noises from the tank
• Water is leaking around the base
• Inconsistent hot water

How often should I flush my water heater?

For homes in the Boise area, we recommend flushing your tank-style water heater once a year to remove sediment buildup. Hard water minerals common in Idaho can settle at the bottom of your tank, causing noise, corrosion, and efficiency loss. 

Start flushing early on in the life of your water heater—waiting too long can lead to significant sediment buildup, which can cause plumbing damage. 

Western Heating & Air Conditioning offers professional water heater maintenance that helps extend system life and performance.

What are the signs of a sewer line problem?

Sewer line issues often show up as:

• Slow drains or frequent backups
• Gurgling noises in pipes or toilets
• Foul sewage odors from drains
• Wet spots or lush patches in your yard
• Multiple fixtures clogging at once

If you suspect a sewer issue, call Western Heating & Air Conditioning. We use camera inspections to pinpoint the problem and offer trenchless repair options whenever possible.

Why does my drain smell bad?

Foul drain odors can come from:

• Dry P-traps (especially in unused sinks)
• Clogged vents or buildup of organic material
• Sewer gas leaks or bacterial growth

Running water down the drain or cleaning it with baking soda and vinegar may help, but if the smell persists, Western Heating & Air Conditioning can clean the drain lines and inspect for deeper issues.

What causes a toilet to run continuously?

A constantly running toilet usually indicates:

• A worn-out flapper that doesn’t seal properly
• A misaligned float or fill valve
• A corroded flush lever or chain issue

These parts are inexpensive but important. Western Heating & Air Conditioning can repair or replace faulty components quickly and check for any underlying issues with your home’s plumbing system.

Why is my faucet dripping, and how can I fix it?

Dripping faucets are typically caused by:

• A worn-out washer or O-ring
• Corrosion or mineral buildup
• Loose or damaged valve seats

While DIY kits exist, improper repairs can lead to worse leaks. Western Heating & Air Conditioning can replace faulty faucet parts or recommend new fixtures if needed—helping you conserve water and lower your utility bill.
