10 Best HVAC Companies in Wilmette, IL

Signs You May Need HVAC Repair or Replacement

If your home's HVAC system is malfunctioning or getting old, you may need to hire an HVAC contractor for repairs or replacement. Look for these common signs that your system needs professional attention:

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

If you see any of these HVAC issues, you should have a technician inspect your system. A local professional can detect problems and decide whether repairing or getting a new HVAC unit is the best solution.

Cost of HVAC Installation and Maintenance in Wilmette

What you spend on HVAC installation or maintenance depends on your system type. Common HVAC unit styles include the following:

• Split or mini-split: If your home doesn't have the right ductwork for central heating or air, you likely have a split HVAC system. Split or mini-split systems consist of internal units that regulate the temperature in individual rooms. These interior units are all connected to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions very similarly to a standard split system. It has the benefit of having the capability to use either electricity or gas for power.
• Heat pump: Heat pumps circulate hot and cool air between your home and the outdoors. They don't generate their own heat or AC, so they perform best in temperate climates.
• Packaged heating and air: Packaged HVAC systems are a good choice for smaller houses. They have a single cooling and heating unit, typically in an attic or basement. This unit is often small, energy-efficient, and easy to maintain.

The cost of HVAC maintenance also depends on the kind of work you're having done. HVAC systems are complicated and might require different kinds of maintenance. The cost of some common repairs is 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. Fortunately, there are steps you can take to reduce wear and tear on your HVAC.

• Monitor for potential problems. Monitoring 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, ductwork, condenser fan blades, and grills clean helps your HVAC system function effectively and lowers your risk of mold. The National Air Duct Cleaners Association recommends cleaning your HVAC system when you notice things starting to get dirty.
• Change filters regularly. Changing or cleaning your air filters every 1–3 months helps air flow smoothly through your HVAC system. You should also try to prevent dirt and debris from building up around the outdoor sections of your system.
• Change the position of your blinds seasonally. Keeping your blinds closed in the summer helps block out passive solar heat. Keeping them open in the winter helps you take advantage of this same heat. Both of these measures help reduce the strain on your HVAC system.

How To Choose a Local HVAC Company

Knowing the indicators of a good HVAC company is important. A properly licensed contractor with the right experience will give you confidence that they can maintain your HVAC system properly, providing you with effective heating and cooling in your home.

Compare Multiple Bids

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

Check Credentials

When selecting an HVAC company, choose one with technicians that have the right training, licenses, and experience. HVAC contractors in all states must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for any individual who helps "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." An individual 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. Be sure to check with your municipal government to verify that your contractor meets all the requirements. You can verify an Illinois business license on the Secretary of State's website. You should also check reviews and complaints on sites like the Better Business Bureau (BBB), Google Reviews, and Yelp. Pick a company with positive reviews and testimonials about good customer experiences.

Understand Work Details

Always make sure you know the details of any project. For HVAC repairs, your provider should specify which parts require replacement and why. Confirm that your technician will clean and test your system after repairs are done to verify that it’s working properly. When replacing your HVAC, ask your installation company to provide details on the new brand, features, model, estimated installation time, and energy efficiency. Before work begins, make sure you understand how your provider will properly size the new unit for your home and what the cost will be.

Compare Warranties

A reputable HVAC company will stand behind its repair work and installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully compare the fine print between contractors and choose the provider that offers the most protection within your budget.

Get Quote in Writing

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