Common Air Conditioning FAQs in Harrisburg, PA

As homeowners in Harrisburg, PA, prepare for the hot summer months, many find themselves with questions about their air conditioning systems. At WM Buffington Company Heating, Cooling & Plumbing, we understand how important it is to keep your home cool and comfortable. Whether you're dealing with a malfunctioning AC unit or simply want to know more about maintaining it, our expert team is here to help. Below, we’ve answered some of the most common questions about air conditioning to help you make informed decisions about your system.

1. How often should I replace my air conditioning filter?

Changing your air conditioning filter is one of the easiest and most effective ways to maintain your system’s efficiency. As a general rule of thumb, it's recommended to replace your filter every 1-3 months, depending on the type of filter and your home's environment. If you have pets or a lot of dust in your home, you may need to change it more frequently. A clogged filter restricts airflow, reduces system efficiency, and can lead to higher energy costs.

2. Why is my air conditioner not cooling the house properly?

If your air conditioner isn’t cooling your home as it should, several issues could be at play. A common reason is low refrigerant levels, which could be a sign of a leak. Another possibility is a dirty air filter or coils, which restrict airflow and prevent your system from working efficiently. If your system is old, it could also be struggling to keep up with your cooling needs. Contact WM Buffington Company to have a professional HVAC technician inspect and diagnose the issue.

3. How can I improve the efficiency of my air conditioner?

To improve the efficiency of your air conditioner, start by scheduling regular maintenance. This includes cleaning the coils, checking refrigerant levels, and replacing filters. Additionally, using a programmable thermostat can help control your home’s temperature more efficiently, reducing energy usage when you're not home. You can also improve your home’s insulation and seal any air leaks to prevent cool air from escaping. A well-maintained system can run up to 15% more efficiently, saving you money on energy bills.

4. What are some signs that my air conditioner needs repair?

Some common signs that your air conditioner may need repair include poor airflow, strange noises (like grinding or banging), water leakage, or inconsistent cooling. If your system is blowing warm air or making unusual sounds, it’s important to call a professional right away to avoid further damage. Scheduling annual maintenance can often catch small issues before they become major repairs, helping your system last longer and run more efficiently.

5. How long should an air conditioner last?

The lifespan of an air conditioning system typically ranges from 10 to 15 years, depending on factors like maintenance, usage, and the quality of the unit. Regular professional maintenance can extend the life of your system, helping it perform at its best for as long as possible. If your system is nearing the end of its lifespan and requiring frequent repairs, it might be time to consider a replacement.

6. What size air conditioner do I need for my home?

Choosing the right size air conditioner is crucial for optimal performance and efficiency. An air conditioner that is too small will struggle to cool your home, while one that is too large can waste energy and leave the air humid. A professional HVAC technician can perform a load calculation to determine the proper size based on factors like the size of your home, insulation, and the number of windows. This ensures your system will keep your home cool without overworking itself.

7. What’s the difference between a central air system and a ductless mini-split system?

A central air system uses ducts to distribute cool air throughout your home, while a ductless mini-split system doesn’t require ducts at all. Ductless systems are ideal for homes without existing ductwork or for cooling specific rooms. They are also more energy-efficient because they avoid energy loss associated with ductwork. Central air systems are generally more affordable to install in homes with existing ducts, but ductless systems offer flexibility and precise control over cooling different areas of the home.

8. Why is my air conditioner making a strange noise?

If your air conditioner is making a strange noise, it’s usually a sign that something isn’t functioning properly. Common noises include rattling, buzzing, grinding, or hissing. Rattling can indicate loose parts, while buzzing could be a sign of electrical issues. Grinding noises often indicate problems with the motor or fan. If you hear strange sounds, it's best to call an HVAC technician right away to prevent further damage to your system.

9. Can I install an air conditioner myself?

While it may be tempting to install an air conditioner yourself, it's generally not recommended. Professional installation ensures that your unit is properly sized, connected, and functioning as efficiently as possible. A poorly installed air conditioner can result in system inefficiencies, safety hazards, and even void your manufacturer’s warranty. It’s always best to rely on a licensed HVAC technician for proper installation to avoid complications down the line.

10. How often should I schedule professional maintenance for my air conditioner?

It’s recommended to have your air conditioner professionally serviced at least once a year, ideally before the cooling season begins. Annual maintenance ensures that your system is running efficiently and helps catch any minor issues before they become major problems. Regular maintenance includes cleaning the coils, checking refrigerant levels, and inspecting the system for wear and tear. This proactive approach can extend the lifespan of your AC unit and improve its performance.

11. What is SEER, and why is it important when choosing an air conditioner?

SEER stands for Seasonal Energy Efficiency Ratio, and it’s a measure of an air conditioner’s efficiency. The higher the SEER rating, the more efficient the system is, which means it will use less energy to cool your home. When purchasing a new air conditioner, look for one with a high SEER rating to save money on energy bills over the long term. New air conditioners are required to have a minimum SEER rating of 13, but systems with ratings of 16 or higher offer significantly better efficiency.

12. How do I know if I need a new air conditioner or if I can repair my current one?

If your air conditioner is more than 10 years old and requires frequent repairs, it may be more cost-effective to replace it rather than continue to repair it. Additionally, if the cost of repairs exceeds 50% of the cost of a new unit, replacement is often the better option. Newer air conditioners are more energy-efficient, which can save you money on energy bills. A professional HVAC technician can help you determine whether repair or replacement is the best choice for your situation.

13. Can a smart thermostat help my air conditioner run more efficiently?

Yes, a smart thermostat can help your air conditioner run more efficiently by allowing you to program temperature changes based on your schedule. Smart thermostats can also learn your preferences and adjust temperatures accordingly, which can lead to lower energy bills. They can even be controlled remotely via a smartphone, giving you full control over your home's temperature. Upgrading to a smart thermostat is a simple yet effective way to improve your air conditioner's efficiency.

14. Why is my air conditioner blowing warm air?

If your air conditioner is blowing warm air, it could be due to several reasons. One of the most common is low refrigerant levels, which could indicate a leak in the system. Another possibility is a dirty air filter, which restricts airflow and causes your system to underperform. It could also be an issue with the thermostat or a malfunctioning compressor. A professional technician can inspect your system and determine the root cause of the problem.

15. How can I reduce my energy bills with my air conditioner?

To reduce your energy bills with your air conditioner, start by scheduling regular maintenance to keep your system running efficiently. Installing a programmable thermostat can help you adjust the temperature when you’re not home, saving energy. Additionally, ensure that your home is properly insulated and that windows are sealed to prevent cool air from escaping. Upgrading to an energy-efficient model can also significantly reduce your energy costs over time.
