Signs You May Need HVAC Repair or Replacement

A malfunctioning or aging HVAC system probably needs professional attention from a technician who can make repairs or install a new unit. Look out for these common indicators that your HVAC needs service:

  • Corrosion, rust, or cracking
  • Thermostat malfunctions or temperature control issues
  • Strange noises when the system turns on
  • Uneven heating/cooling or poor air circulation
  • Frequent breakdowns and need for repairs
  • Refrigerant leaks
  • Unusually high energy bills
  • An HVAC system that's over 15 years old

If you notice any of these HVAC issues, we recommend having a technician inspect your system. A local professional can diagnose problems and decide whether fixing or replacing your HVAC unit is the best solution.

Cost of HVAC Installation and Maintenance in Carol Stream

What you spend on HVAC installation or maintenance varies based on your system style. Common HVAC unit styles include the following:

  • Split or mini-split: If your home doesn't have the right ductwork for central air or heating, you likely have a split HVAC system. Split or mini-split systems consist of internal units that regulate the temperature in individual rooms, and that 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 being able to utilize either gas or electricity for power.
  • Heat pump: Heat pumps circulate warm and cold air between your home and the outdoors. They don't generate their own heat or AC, so they work best in moderate climates.
  • Packaged heating and air: Packaged HVAC systems are a smart choice for smaller homes. They have a single heating and cooling unit, normally in an attic or basement. This unit is often space-saving, energy-efficient, and easy to maintain.

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

HVAC Unit Type Cost
Split $2,006-$5,115
Hybrid Split $4,066-$7,490
Heat Pump $3,148-$32,077
Packaged Heating and Air $263-$439

Ways to Save Money on HVAC Costs

It's important to repair or replace your HVAC system when it's broken, but it can also be expensive. Fortunately, there are some steps you can take to reduce wear and tear on your HVAC.

  • Change filters regularly. Replacing or cleaning your air filters every 1–3 months helps air flow efficiently through your HVAC system. We also recommend regularly clearing dirt and debris away from the external parts of your system.
  • Change the position of your blinds seasonally. Leaving your blinds open during the winter helps warm your home with passive solar heating. Closing the blinds in warmer seasons helps prevent some heat from getting inside. Doing both helps reduce the demand on your HVAC system.
  • Monitor for potential problems. Monitor your system for issues, for example by consistently checking your thermostat and energy bills. This enables you to address issues before they get too expensive.
  • Keep your system clean. Keeping your ductwork, condenser fan blades, indoor evaporator coil, and grills clean helps your system function optimally and reduces the chance of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system whenever it begins to look dirty.

Service Cost
Filter Replacement $66-$176
Condensor Cleaning $1,317-$3,951
Thermostat Repair $88-$220
Ductwork Cleaning $421-$1,054

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is key for a smooth installation or repair. Hiring an experienced, credentialed HVAC contractor gives you confidence your system can provide reliable heating and air conditioning year-round.

Compare Multiple Bids

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

Check Credentials

When selecting an HVAC company, choose one with technicians that have the appropriate training, licenses, and experience. In all states, HVAC contractors must 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." 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 also verify an Illinois business license on the Secretary of State's website. You should also read reviews and complaints on sites like Google Reviews, the Better Business Bureau (BBB), and Yelp. Choose a company with glowing reviews and testimonials about good customer experiences.

Understand Work Details

Always make sure you know what a company’s process is like. When getting HVAC repairs, ask your provider to specify which parts require replacement and why. Confirm that your technician will clean and test the system afterward to verify proper operation. When replacing your HVAC system, ask the installation company to provide details on the new estimated installation time, features, model, energy efficiency, and brand. 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

Trustworthy HVAC companies provide warranties for their services. Broader coverage is better, so make sure to review warranties between companies. Choose the one that offers the best coverage at a fair cost.

Get Quote in Writing

Always get estimates for HVAC service in writing before committing to a provider. An itemized quote should cover both labor and materials. Make sure you agree to all terms before signing a contract.

Frequently Asked Questions About HVAC in Carol Stream, IL

You should have your HVAC system inspected about twice yearly. After the inspection, your technician will tell you what services are required. You should also call a technician if you notice new issues such as unusual smells, strange noises, or leaks. If your home has ductwork, it should be inspected every few years.

Normally, it's best to have your HVAC system inspected in the spring and fall, as technicians tend to be less busy at these times. This also helps get your system ready for the summer and winter, when it likely sees the most use.

You can save energy throughout the year by reducing the amount of power your HVAC system uses to maintain your home's temperature. During all seasons, keep your thermostat as close to the outside temperature as possible, and try to adjust it only a few degrees at a time. You could also consider a smart thermostat.

It takes around one to three days to have an HVAC system installed or replaced. If you only need an air conditioning unit or a furnace, this might take anywhere from a few hours up to two days. This timeline will be affected by the size of your house, how easily accessible your system is, and any new issues your technician runs into.

For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. If your home is larger than 1,000 square feet, central air is likely to be more effective than window units for cooling.

For a 2,000-square-foot home, you'll also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units).

Your HVAC company might offer financing options through a third-party lender, or you may be able to obtain a loan on your own. It's smart to discuss payment options with your HVAC company and a financial advisor to make sure that you find the best option for you.
