6. How does HVAC financing work?

HVAC financing spreads the cost of a new system over monthly payments. You apply through a lender of your choice or directly through one of our financing partners.

8. What is SEER2?

SEER2 stands for Seasonal Energy Efficiency Ratio 2. It measures how efficiently an air conditioner or heat pump cools your home over a season. The higher the SEER2 rating, the more energy-efficient the system is. SEER2 is a newer standard that gives a more accurate picture of real-world performance than the old SEER rating.

9. Why is my AC blowing warm air?

A few common culprits of warm air from your air conditioner 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 Sales & Services. We’ll get your [city-1], home comfortable again in no time. We’ve been finding HVAC solutions for homeowners in Jefferson and Shelby counties since 1948.

10. Why is my air conditioner freezing up? 

Ice buildup could be caused by dirty filters, low refrigerant, or poor airflow. To avoid further damage, turn the system off and call Western Sales & Services for AC repair.

11. Do you install and service furnaces in Birmingham? 

Yes! If you have been searching for “furnaces in Birmingham,” Western Sales & Services is your go-to team for expert help. We specialize in American Standard furnace installations in Birmingham, and nearby communities like Homewood, and Hoover.  

We also repair and maintain all furnace brands and models. 

12. What is AFUE? 

AFUE, or annual fuel utilization efficiency, is a rating that shows how effectively a furnace converts fuel into usable heat. Higher numbers mean better efficiency.

13. Why is my furnace blowing cold air?

If your furnace 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 furnace 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 furnace may fail to light the burners—even though the blower fan continues to run.

Our NATE-certified team at Western Sales & Services can perform a thorough furnace inspection to quickly identify the issue and restore warm air to your Birmingham, home.

14. Where is my HVAC filter located?

Your HVAC air filter may be located inside the return air grille, in the furnace cabinet, or near the air handler unit. During a maintenance visit, our technician can help you locate and access the filter to ensure regular replacement.

15. Can you install and service heat pumps in [linked-city-1]?

16. What is HSPF2?

HSPF2 stands for Heating Seasonal Performance Factor 2. It measures how efficiently a heat pump heats your home over a season. Like SEER2 (the cooling efficiency rating), a higher HSPF2 rating means better energy efficiency. HSPF2 is part of updated testing standards that better reflect how systems perform in real homes.

17. What’s the difference between a heat pump and a gas furnace?

A heat pump uses electricity to move heat, working as both a heater and an air conditioner. In contrast, a gas furnace burns natural gas to generate heat.

Here in Alabama, where winters are mild, heat pumps are often more energy-efficient and cost-effective because they don’t rely on fuel combustion.

18. Can a heat pump replace my furnace and air conditioner? 

Absolutely. A heat pump can serve as both your heating and cooling system in Birmingham, Homewood, and all the surrounding communities in Jefferson and Shelby County. Western Sales & Services, founded in 1948, is a leader in installing heat pumps for homes and businesses throughout Alabama.

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

A ductless mini split is a heating and cooling system that doesn’t require ductwork. It consists of an indoor air handling unit and an outdoor compressor. The system transfers heat between the indoor and outdoor units using a refrigerant, providing efficient, zoned climate control for individual rooms or areas.

Ductless mini splits add comfort in additions, finished garages and basements, and other areas without ductwork.

20. Are ductless mini splits a good option for older homes in Birmingham?

Absolutely. Ductless mini splits are ideal for older homes without ductwork in Birmingham, Homewood, Hoover, and other nearby communities. They offer an efficient, non-invasive heating and cooling solution without the need for major renovations or structural changes.

Our NATE-certified technicians install, repair, and maintain ductless systems throughout West Jefferson County.

21. Can a ductless mini split heat and cool my entire Alabama home?

Yes, a multi-zone ductless system can heat and cool an entire Birmingham, home. Multiple indoor units can be connected to a single outdoor unit, allowing for customized climate control in each room without the need for ductwork.

22. Do you offer water heater repair and replacement in Birmingham? 

Yes, our water heater repair and replacement services are available in Birmingham, and the surrounding areas. Whether you have a traditional tank or tankless water heater, our professionals at Western Sales & Services can help.

• Dust, pet dander, and pollen 
• Mold and mildew 
• Household cleaning products 
• Tobacco smoke 
• Poor ventilation 
• Combustion appliances (gas stoves, furnaces)

26. Should I close vents in unused rooms to save energy? 

Closing vents in unused rooms may seem like a good way to save energy, but it can actually have the opposite effect. Most modern HVAC systems are designed to balance airflow throughout the entire home.

When you close vents, it can increase pressure in the ductwork, causing your system to work harder and less efficiently. This added strain can lead to higher energy bills, reduced comfort, and even premature wear on your HVAC system.

Instead of closing vents, consider using a programmable thermostat, installing an HVAC zoning system, or adding energy-efficient upgrades to better manage heating and cooling in your home.

Our professionals at Western Sales & Services can help recommend the best HVAC solutions for your home.

27. What boiler services do you provide in Birmingham, and the surrounding areas?

Western Sales & Services provides a full range of residential boiler services in Birmingham, Homewood, and nearby communities. Our services include boiler installation, replacement, repairs, routine maintenance, system inspections, and emergency boiler service.

Whether you have a gas, electric, or oil boiler, our experienced technicians are equipped to keep your system running safely, efficiently, and reliably year‑round.

28. Why is my boiler making banging or whistling noises?

Banging, knocking, or whistling noises are often caused by a condition known as “kettling,” which occurs when mineral buildup restricts water flow and causes overheating. Whistling sounds can also indicate trapped air, pressure issues, or a failing pump. These noises should never be ignored, as they can signal internal damage to your boiler. A professional inspection from Western Sales & Services can identify the cause and prevent further issues.

29. Do you offer radiant floor heating?

Yes! In fact, Western Sales & Services is one of the few contractors in the state of Alabama qualified to install and service hydronic floor heating systems.
