10 Best HVAC Companies in Long Grove, IL

Signs You May Need HVAC Repair or Replacement

If your home's HVAC system is malfunctioning or getting old, you might need an HVAC contractor for maintenance or replacement. Look for these common indicators that your system needs professional attention:

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

If you see any of these HVAC issues, we recommend having a technician inspect your system. A local professional can diagnose problems and decide whether repairing or getting a new HVAC unit is the correct solution.

Cost of HVAC Installation and Maintenance in Long Grove

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

• Split or mini-split: If your home's ductwork can't accommodate a central HVAC system, you probably have a split or mini-split system. Split systems have interior units in each room to regulate temperature; these indoor units all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions in the same way as a normal split system, but has the benefit of being able to utilize energy from either gas or electric sources.
• Heat pump: Heat pumps exchange hot and cold air between your home and the outside. These systems don't produce their own heat or AC, so they work more efficiently in milder climates.
• Packaged heating and air: Packaged HVAC systems are more popular in smaller homes. These systems consist of a single heating and cooling unit that's typically located in a basement or attic. This unit tends to be efficient, compact, and easy to maintain.

HVAC maintenance prices vary depending on the particular service needed. HVAC systems are complicated and might require different maintenance services. Fees for some common services are as follows:

Ways to Save Money on HVAC Costs

Repairing or replacing your HVAC system when needed is crucial, but can be costly. Fortunately, there are actions you can take to reduce gradual wear and tear on your system.

• Monitor for potential problems. Monitoring the efficiency of your HVAC system — for instance by checking your thermostat settings and energy bills — helps you identify and fix problems before they get too expensive.
• Change filters regularly. Air flows best 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 outside areas of your HVAC.
• 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 strain on your HVAC system.
• Keep your system clean. Keeping your ductwork, grills, condenser fan blades, and indoor evaporator coil clean enables your HVAC system to function properly and lowers the risk of mold. The National Air Duct Cleaners Association recommends cleaning your HVAC when you notice things starting to get dirty.

How To Choose a Local HVAC Company

Knowing the indicators of a reliable HVAC company is key for a smooth installation or repair. 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 contractors for quotes. Describe your issues and schedule an in-person inspection if possible. Compare contractors' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid providers that pressure you or demand upfront payment.

Check Credentials

When picking an HVAC provider, 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 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 by the state.

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 of the requirements. You can verify an Illinois business license on the Secretary of State's website. Also look at a company's reviews and complaints on sites such as the Better Business Bureau (BBB), Google Reviews, and Yelp. Pick a company with glowing feedback and stories of satisfied customers.

Understand Work Details

Always make sure you know the details of a planned project. For HVAC repairs, your provider should detail which parts require replacement and why. Confirm that your technician will clean and test the system after repairs are finished to verify that it’s working properly. When replacing your HVAC, have the provider describe the new model, features, brand, estimated installation time, and energy efficiency. Before signing a contract, ask how your provider plans to accurately size the unit for your home and how much it will cost.

Compare Warranties

Reliable HVAC companies offer warranties on repairs and equipment installations. The more complete the coverage, the better. Review warranty details between providers and pick the one that offers the best protection for a fair price.

Get Quote in Writing

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