Signs You May Need HVAC Repair or Replacement

An HVAC system that's malfunctioning or old likely needs professional attention for repairs or replacement. Watch for these signals that your system needs service:

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

These HVAC red flags indicate that you should have 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 Chatham

Your HVAC installation or maintenance cost changes depending on the type of unit. Common HVAC unit varieties include the following:

  • Split or mini-split: If your home doesn't have 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, and that are all connected to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system works almost the same as a standard split system. It has the benefit of being able to utilize either electricity or gas for power.
  • Heat pump: Heat pumps exchange warm and cold air between your home and outside. They don't make their own heat or AC, so they function best in temperate climates.
  • Packaged heating and air: Packaged HVAC systems are a smart choice for smaller homes. These systems have a single combined AC and heating, typically located in a basement or attic. They're small, cost-effective, and easy to maintain.

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

HVAC Unit TypeCost
Split$1,840-$4,690
Hybrid Split$3,728-$6,868
Heat Pump$2,886-$29,411
Packaged Heating and Air$242-$403

Ways to Save Money on HVAC Costs

It’s important to complete repairs or full-system HVAC replacements as needed, though they can be expensive. The good news is that homeowners have ways to minimize progressive deterioration and reduce the frequency of breakdowns.

  • Change filters regularly. Switching out your air filters or washing them every 1–3 months allows smooth air circulation through your system. Also try to keep debris from accumulating on the external parts of your HVAC.
  • Keep your system clean. Regularly cleaning ductwork, grills, indoor evaporator coil, and condenser fan blades helps keep your HVAC system running efficiently and reduces the risk of mold. The National Air Duct Cleaners Association recommends cleaning your heating and cooling system when it starts to look dirty.
  • Monitor for potential problems. Monitoring the efficiency of your HVAC system — for instance by reviewing your thermostat settings and energy bills — helps you identify and fix problems before they get out of hand.
  • Change the position of your blinds seasonally. Leaving your blinds open during the colder months allows passive solar heating to warm your home. Closing the blinds during the summer helps prevent the heat from getting inside. Doing both helps decrease the demand on your HVAC system.
ServiceCost
Filter Replacement$60-$161
Condensor Cleaning$1,208-$3,623
Thermostat Repair$81-$201
Ductwork Cleaning$386-$966

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is important for a successful project. Partnering with an experienced, licensed contractor can give you peace of mind and ensure your system provides reliable air conditioning and heating for your home.

Compare Multiple Bids

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

Check Credentials

Look for an HVAC company that employs skilled technicians who have the necessary training and licenses. In all states, HVAC contractors must 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." 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 on a state-by-state basis.

Illinois doesn't have state-level contractor licensing requirements. 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 Google Reviews, the Better Business Bureau (BBB), and Yelp. Pick a company with great feedback and stories of satisfied customers.

Understand Work Details

Always make sure you know the details of your project. For HVAC repairs, your provider should list which parts need replacement and why. Confirm that your technician will clean and test your system after repairs are finished to verify that it’s working properly. When replacing your HVAC, have the contractor explain the new estimated installation time, features, model, brand, and energy efficiency. Before signing paperwork, be sure you understand how your provider will determine the right system size for your home and what the price will be.

Compare Warranties

Trustworthy HVAC companies stand behind their work with warranties. Compare warranties from different companies, remembering that broader coverage is better. Look for the company that provides the most coverage for a reasonable price.

Get Quote in Writing

Get written quotes before starting any HVAC work. The quote should outline costs for both labor and materials. Read all terms carefully before signing.

Frequently Asked Questions About HVAC in Chatham, IL

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

Usually, it's a good idea 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 probably sees the most use.

You can save energy throughout the year by making it easier for your HVAC system 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 purchasing a smart thermostat.

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

For a 2,000-square-foot home, you'll also want to look for an air conditioning unit with between 2.5 and 5 tons of capacity. Usually, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.

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

There are a number of ways you can make your HVAC system more energy-efficient:

  • Keep ductwork clean, and change or clean your air filters regularly.
  • Have regular inspections to take care of issues as they come up.
  • Make sure your doors and windows are well-sealed and keep your attic well-ventilated.
  • Install a smart thermostat. If you aren't able to purchase one, try keeping the temperature indoors as close to the outside temperature as you can.
  • When replacing part of your system, explore Energy Star-certified or other environmentally friendly options.
