10 Best HVAC Companies in Northbrook, IL

Signs You May Need HVAC Repair or Replacement

An HVAC system that's malfunctioning or outdated likely needs professional attention for maintenance or replacement.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

• Refrigerant leaks
• Higher than normal energy bills
• Corrosion, cracking, or rust
• Temperature control issues or thermostat malfunctions
• Frequent breakdowns and need for repairs
• Odd noises when the system turns on
• Uneven heating/cooling or poor air circulation
• An HVAC system that's over 15 years old

If you notice any of these HVAC red flags, your system evaluated. A local provider can complete an inspection, identify problems, and advise you whether you should repair or replace your HVAC unit.

Cost of HVAC Installation and Maintenance in Northbrook

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

• Split or mini-split: If your home doesn’t have the ductwork for central heating and cooling, you likely have a split or mini-split system instead. Split HVAC systems have internal units in each room to control temperature. These connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions much like a standard split system, but has the capacity to draw on either gas or electricity as energy sources.
• Heat pump: Heat pumps work by moving hot and cold air between your home and the outdoors. These systems don't create heat or air conditioning themselves, and are more suited to more moderate climates.
• Packaged heating and air: Packaged HVAC systems are a good choice for smaller homes. These systems have a single combined AC and heating, normally located in a basement or attic. They're compact, cost-effective, and easy to maintain.

HVAC maintenance prices vary depending on what services are needed. HVAC systems are complex and may require different maintenance services. Costs for some common services are as follows:

Ways to Save Money on HVAC Costs

It's important to take care of HVAC repairs and replacements in a timely manner, but it can also be expensive. Fortunately, there are some steps you can take to slow the wear and tear on your system.

• Change filters regularly. Replacing or cleaning your air filters every 30–90 days 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 open in the winter helps you take advantage of passive solar heating. Keeping them closed in the summer helps keep some of this heat out. Both of these measures help reduce the frequency with which you need to run your HVAC.
• Monitor for potential problems. Monitoring your system for problems — for example, by checking your thermostat and energy bills regularly — helps you get ahead of problems before they get too expensive.
• Keep your system clean. Cleaning your ductwork, condenser fan blades, indoor evaporator coil, and grills regularly helps your HVAC system work efficiently and lowers the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.

How To Choose a Local HVAC Company

It's important to know what makes a good HVAC company. A properly licensed contractor with the right experience will give you confidence that they can maintain your HVAC system properly, providing you with effective air conditioning and heating for your home.

Compare Multiple Bids

Request estimates from at least three HVAC contractors. Describe your issues and ask if technicians can inspect your system in person. Compare each contractor's diagnoses, recommended solutions, estimated cost, warranties, and timelines. Avoid companies that pressure you or demand payment before work.

Check Credentials

When looking for an HVAC company, choose one with technicians that have the proper training, licenses, and experience. HVAC contractors in all states need to 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 what kind of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled at the state level.

There are no state-level licensing requirements for contractors in Illinois. However, there may be local regulations. Be sure to check with your municipal government to confirm that your contractor meets all the requirements. You can also verify an Illinois business license on the Secretary of State's website. You should also look at reviews and complaints on sites like Yelp, Google Reviews, and the Better Business Bureau (BBB). Choose a company with positive reviews and reports of great customer experiences.

Understand Work Details

Make sure you understand the details of your project before starting. For HVAC repairs, have your provider specify 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. For replacement, ask your contractor to explain the new HVAC system energy efficiency, model, estimated installation time, features, and brand. Before signing a contract, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

A trustworthy HVAC company will back its repair services and installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully compare the fine print between contractors and choose the provider that offers the greatest protection at a reasonable price.

Get Quote in Writing

Always get HVAC estimates in writing before work begins. A thorough quote covers costs for both materials and labor. Ensure that you agree to all terms before signing the contract.
