10 Best HVAC Companies in Northfield, IL

Signs You May Need HVAC Repair or Replacement

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

• Temperature control issues or thermostat malfunctions
• Corrosion, rust, or cracking
• Frequent breakdowns and need for repairs
• Odd noises when the system turns on
• Unusually high energy bills
• Refrigerant leaks
• 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 company can complete an inspection, diagnose problems, and advise you whether you should repair or replace your HVAC unit.

Cost of HVAC Installation and Maintenance in Northfield

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

• Split or mini-split: If your home lacks the right ductwork for central heating or air, you likely have a split HVAC system. Split or mini-split systems consist of interior 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 has the capacity to draw on either electricity or gas for power.
• Heat pump: Heat pumps move hot and cold air between your home and the outside. These systems don't generate their own heat or AC, so they work better in more temperate climates.
• Packaged heating and air: Packaged HVAC systems are a good choice for smaller houses. They have a single heating and cooling unit, usually in an attic or basement. This unit is often compact, energy-efficient, and easy to maintain.

HVAC maintenance costs differ depending on what services are needed. HVAC systems are complex and might require different maintenance services. Prices for common services 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. Fortunately, there are actions you can take to minimize wear and tear over time on your system.

• Keep your system clean. Regularly cleaning condenser fan blades, grills, ductwork, and indoor evaporator coil helps keep your HVAC system running efficiently and reduces your risk of mold. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.
• Monitor for potential problems. Monitor your system for issues, for example by consistently checking your thermostat and energy bills. This enables you to address problems before they get out of hand.
• Change filters regularly. Cleaning or replacing your air filters every 1–3 months helps air flow smoothly through your system. You should also try to keep debris away from the outdoor portions of your HVAC system as much as possible.
• Change the position of your blinds seasonally. During winter, leaving your blinds open allows your home to benefit from passive solar heating. In the summer, keeping your blinds shut helps to block out heat. Doing both lowers the amount of work your HVAC system needs to do.

How To Choose a Local HVAC Company

Knowing the indicators of a good HVAC company is important. Working with a contractor that's properly licensed and highly experienced will give you confidence that they can maintain your HVAC system properly, providing you with effective air conditioning and heating in your home.

Compare Multiple Bids

Contact at least three HVAC providers for quotes. Describe your issues and schedule an in-person inspection if possible. Compare providers' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid providers that pressure you or demand upfront payment.

Check Credentials

When selecting an HVAC provider, 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 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 verify that your contractor meets all of the requirements. You can also verify an Illinois business license on the Secretary of State's website. You should also look at a company's reviews and complaints on sites such as the Better Business Bureau (BBB), Yelp, and Google Reviews. Pick a company with glowing feedback and good customer testimonials.

Understand Work Details

Make sure you understand the details of any project before starting. For HVAC repairs, have your provider detail which parts require replacement and why. Get confirmation that your technician will clean and test the entire system after the repair to ensure that everything works. When getting a replacement, ask the contractor to explain the new HVAC system estimated installation time, model, features, energy efficiency, 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

Reputable HVAC companies stand behind their work with warranties. Look at warranties from different companies, remembering that more comprehensive coverage is better. Look for the provider that offers the most coverage for a reasonable price.

Get Quote in Writing

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