10 Best HVAC Companies in Lisle, IL

Signs You May Need HVAC Repair or Replacement

A faulty or aging HVAC system probably needs professional attention from a technician who can make fixes or install a new unit. Watch out for these common signs that your HVAC needs service:

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

If you notice any of the above, have a local HVAC technician inspect your system. They can diagnose problems and determine whether repair or full HVAC replacement is required.

Cost of HVAC Installation and Maintenance in Lisle

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

• Split or mini-split: If your home lacks the right ductwork for central air or heating, you probably 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 performs similarly to a standard split system, but is able to utilize either electricity or gas as energy sources.
• Heat pump: Heat pumps exchange hot and cold air between your house and the outdoors. They don't make their own heating and cooling, so they work more efficiently in more mild climates.
• Packaged heating and air: Packaged HVAC systems are a smart choice for smaller homes. They have a single heating and cooling unit, typically in an attic or basement. This unit is often small, cost-effective, and easy to maintain.

HVAC expenses vary based on the services needed. HVAC systems are complicated and may need several types of maintenance. Costs for common jobs are as follows:

Ways to Save Money on HVAC Costs

Taking care of necessary HVAC repairs and replacements when needed is crucial, but can be expensive. Thankfully, there are steps you can take to minimize wear and tear over time on your system.

• Monitor for potential problems. Keeping an eye out for problems, for instance by consistently checking your thermostat and energy bills, helps you resolve them before they get too expensive.
• Change the position of your blinds seasonally. During winter, leave your blinds open so your home benefits from passive solar heat. In summer, keep blinds shut to block out heat. Doing both lowers the amount of work your HVAC system is required to do.
• Change filters regularly. Switching out your air filters or washing them every 30–90 days allows efficient air circulation through your system. Also try to keep debris from accumulating on the outside components of your HVAC.
• Keep your system clean. Keeping your condenser fan blades, indoor evaporator coil, grills, and ductwork clean helps your system run and reduces 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. Working with a contractor that's properly licensed and highly experienced will give you confidence that they can keep your system running efficiently, providing you with effective heating and cooling for 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

Look for an HVAC company that employs skilled technicians who have the necessary licensure and training. HVAC contractors in all states need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required 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 what kind of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled on a state-by-state basis.

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

Understand Work Details

Always make sure you understand what a company’s process looks like. When HVAC repairs are needed, ask your provider to explain which parts require replacement and explain why. Confirm that your technician will clean and test the full system after finishing the work to verify proper operation. When getting a replacement, ask the contractor to explain the new HVAC system energy efficiency, features, model, estimated installation time, and brand. Before starting the project, you should understand the process your provider will use to properly size the system for your home and the price you'll pay.

Compare Warranties

Good HVAC companies offer warranties on repairs and installations. The more complete the coverage, the better. Review warranty details between providers and pick the one that offers the most comprehensive protection for the fairest price.

Get Quote in Writing

Get a written estimate before HVAC work begins. A comprehensive quote includes both labor and material costs. Make sure you understand and agree to all terms before signing the contract.
