10 Best HVAC Companies in Winnetka, IL

Signs You May Need HVAC Repair or Replacement

An HVAC system that's malfunctioning or old likely needs professional attention for maintenance or replacement. Watch for these signals that your system needs service:

• Cracking, corrosion, or rust
• Odd noises when turning on
• Poor air circulation or uneven heating/cooling
• Unusually high energy bills
• Frequent breakdowns and need for repairs
• Temperature control issues or thermostat malfunctions
• Refrigerant leaks
• An HVAC system that's over 15 years old

If you notice any of these HVAC red flags, your system evaluated. A local technician can complete an inspection, identify problems, and recommend repairing or replacing your HVAC unit.

Cost of HVAC Installation and Maintenance in Winnetka

HVAC installation or maintenance costs vary depending on your system. Common HVAC unit types include the following:

• Split or mini-split: Homes without ductwork for central heating and cooling frequently have split or mini-split HVAC systems. These systems consist of indoor units in each room to regulate temperature. These indoor units connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions very similarly to a standard split system. It has the benefit of being able to utilize either electricity or gas for power.
• Heat pump: Heat pumps exchange warm and cool air between your home and the outdoors. They don't make their own heating and cooling, so they work more effectively in more moderate climates.
• Packaged heating and air: Packaged HVAC systems work well in smaller homes. They consist of a single combined air conditioner and heating unit, commonly located in an attic or basement. This unit is typically space-saving, cost-effective, and easy to maintain.

HVAC expenses vary based on the work needed. HVAC systems are complicated and may need a number of types of maintenance. Prices for common jobs are as follows:

Ways to Save Money on HVAC Costs

It's important to fix or swap out your HVAC components when they become damaged, but it can also be expensive. Thankfully, there are steps you can take to slow the wear and tear on your system.

• Change the position of your blinds seasonally. Leaving your blinds open during the winter allows passive solar heating to warm your home. Closing the blinds during the summer helps prevent the same heat from getting inside. Doing both helps minimize the demand on your HVAC system.
• Monitor for potential problems. Keeping a close eye on the efficiency of your HVAC system — for instance by checking your thermostat settings and energy bills — helps you find and solve issues before they get out of hand.
• Keep your system clean. Keeping your indoor evaporator coil, condenser fan blades, ductwork, and grills clean helps your system function optimally and reduces the chance of mold growth. The National Air Duct Cleaners Association recommends that you clean your HVAC system when it starts to look dirty.
• Change filters regularly. Air flows most effectively through your HVAC system when you change out or clean the filters every 30–90 days. Also try not to let debris pile up on the outdoor parts of your HVAC.

How To Choose a Local HVAC Company

Knowing the right things to look for in an HVAC company is key for a smooth repair or installation. Picking an established business with certified technicians gives you assurance your HVAC system will deliver consistent heating and cooling year-round.

Compare Multiple Bids

Contact at least three HVAC providers for quotes. Describe the issues and have specialists visit to inspect your system if possible. Compare the companies' explanations, solutions, estimated costs, warranties, and timeframes. Avoid companies that pressure you or demand payment upfront.

Check Credentials

When looking for an HVAC company, choose one with technicians that have the right training, licenses, and experience. In all states, HVAC contractors must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for all contractors who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." Contractors must pass an exam (the type of exam depends on the type of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled at the state level.

The state of Illinois doesn't have state-level licensing requirements for contractors. However, there may be local regulations, so make sure to check with your municipal government to confirm that your contractor meets all the requirements. You can verify an Illinois business license on the Secretary of State's website. Checking reviews on the Better Business Bureau (BBB), Yelp, Google Reviews, and similar sites can assist your decision. Choose a company with great reviews and stories of positive experiences from customers.

Understand Work Details

Make sure you know the details of any project before starting. When getting HVAC repairs, have your provider list which parts need replacement and why. Confirm that your technician will clean and test the entire system after the repair to ensure that everything works. When replacing your HVAC system, ask the installation company to provide details on the new model, features, energy efficiency, brand, and estimated installation time. Before work begins, make sure you understand the process your provider will use to select the correctly sized system for your home and what the cost will be.

Compare Warranties

Reliable HVAC companies provide warranties for their services. Broader coverage is better, so make sure to compare warranties between providers. Choose the one that provides the most comprehensive coverage at a reasonable cost.

Get Quote in Writing

Get written estimates before beginning HVAC work. The quote should cover costs for both labor and materials. Review all terms carefully before signing.
