Frequently Asked Questions About HVAC Services

At Magtek Mechanical, we understand that homeowners in New Lenox, Joliet, Frankfort, Mokena, and Tinley Park have many questions about their heating and cooling systems. Here are answers to some of the most common inquiries we receive.

Air Conditioning Service Questions

How often should I have my air conditioning system serviced?

We recommend having your AC system professionally serviced at least once per year, ideally in the spring before the cooling season begins. Regular maintenance helps ensure optimal performance, extends equipment life, and can prevent costly breakdowns during peak summer months.

What are signs that my air conditioner needs repair?

Common warning signs include:

• Insufficient cooling or uneven temperatures throughout your home
• Unusual noises such as grinding, squealing, or banging
• Higher than normal energy bills
• Frequent cycling on and off
• Poor airflow from vents
• Strange odors coming from the system

How long do air conditioning systems typically last?

With proper maintenance, most AC units last 15-20 years. However, factors like usage patterns, maintenance history, and local climate conditions can affect lifespan. Systems that are well-maintained and serviced regularly tend to last longer and operate more efficiently.

Heating Service Questions

When should I schedule heating system maintenance?

The best time to schedule heating maintenance is in the fall, before you need to rely on your system for warmth. This timing allows us to identify and address any issues before they become problems during cold weather.

What types of heating systems do you service?

Our experienced technicians service all major types of heating systems, including:

• Gas furnaces
• Electric furnaces

How can I improve my heating system’s efficiency?

Several steps can help improve efficiency:

• Replace air filters regularly

• Seal air leaks around windows and doors
• Add insulation to your home where needed

HVAC Installation Questions

How do I know when it’s time to replace my HVAC system?

Consider replacement when:

• Your system is over 15 years old and requiring frequent repairs
• Energy bills have increased significantly
• Your home has comfort issues despite repairs
• Repair costs exceed 50% of a new system’s value

What size HVAC system do I need for my home?

Proper sizing requires a professional load calculation that considers factors such as:
