Signs You May Need HVAC Repair or Replacement

If your home's HVAC system is malfunctioning or suffering from a lot of wear and tear, you may need to hire an HVAC contractor for maintenance or replacement. Watch for these common signs that your system needs professional attention:

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

If you're experiencing any of these HVAC issues, you should have a technician inspect your system. A local professional can identify problems and determine whether fixing or replacing your HVAC unit is the correct solution.

Cost of HVAC Installation and Maintenance in Lincolnshire

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

  • Split or mini-split: If your home lacks the ductwork for central air or heating, you likely have a split or mini-split system instead. Split HVAC systems have internal units in each room to control temperature. These connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC unit operates similarly to a regular split system. It provides flexibility by providing the option to draw on either electricity or gas for energy.
  • Heat pump: Heat pumps move warm and cool air between your home and the outside. These systems don't make 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 houses. These systems consist of a single heating and cooling unit that's usually 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 may require different kinds of maintenance. Fees for common services are as follows:

HVAC Unit TypeCost
Split$1,973-$5,030
Hybrid Split$3,998-$7,366
Heat Pump$3,096-$31,544
Packaged Heating and Air$259-$432

Ways to Save Money on HVAC Costs

Repairing or replacing your HVAC system when needed is important, but can be expensive. Fortunately, 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 routinely checking your thermostat and energy bills, helps you resolve them before they get out of hand.
  • Change filters regularly. Switching out your air filters or washing them every 30–90 days allows effective air circulation through your HVAC system. Also try to keep debris from accumulating on the outdoor sections of your HVAC.
  • Keep your system clean. Regularly cleaning condenser fan blades, indoor evaporator coil, grills, and ductwork helps keep your HVAC system running efficiently and lowers your risk of mold. The National Air Duct Cleaners Association recommends cleaning your system when it starts to look dirty.
  • 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.
ServiceCost
Filter Replacement$65-$173
Condensor Cleaning$1,295-$3,886
Thermostat Repair$86-$216
Ductwork Cleaning$414-$1,036

How To Choose a Local HVAC Company

Knowing the right things to look for in an HVAC company is key for a smooth installation or repair. Established providers with certified technicians can offer assurance your HVAC system will deliver consistent heating and cooling year-round.

Compare Multiple Bids

Get quotes from at least three HVAC companies. Explain your issues and ask if technicians can inspect your system in person. Review each provider's diagnoses, recommended solutions, estimated cost, timelines, and warranties. Avoid companies that pressure you or demand payment before work.

Check Credentials

Look for an HVAC company that employs skilled technicians who have the necessary training and licenses. HVAC contractors in all states need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for any individual who helps "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 on a state-by-state basis.

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 of the requirements. You can verify an Illinois business license on the Secretary of State's website. Checking reviews on the Better Business Bureau (BBB), Google Reviews, Yelp, and similar sites can aid your decision as well. Choose a provider with great reviews and stories of positive experiences from customers.

Understand Work Details

It’s important to understand what the work process will look like. For HVAC repairs, the company should explain the particular parts that need replacement and why. Confirm that your technician will clean and test your system afterward to guarantee everything is working correctly. For replacement, ask your contractor to explain the new HVAC system estimated installation time, brand, features, energy efficiency, and model. Before starting the project, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

A trustworthy HVAC company will stand behind its repair work and equipment installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully review warranty terms for each contractor and choose the provider that offers the greatest protection within your budget.

Get Quote in Writing

Always get quotes for HVAC service in writing before committing to a provider. A comprehensive quote should cover both materials and labor. Make sure you review all terms before signing a contract.

Frequently Asked Questions About HVAC in Lincolnshire, IL

Typically, your HVAC system should be inspected twice a year. After that inspection, your HVAC technician will tell you what, if any, services are required. You should also have an inspection if you start to notice any issues, such as leaks, strange noises, or unusual smells. If you have ductwork in your home, it should be serviced every few years.

The best times of the year to have an HVAC inspection are the spring and fall. Technicians are less busy during these times, so it will be easier to get an appointment. This also ensures that your system is ready for the summer and winter, when it typically sees the most use.

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

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

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

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

  • Make sure your air ducts remain clean, and change or clean your air filters regularly.
  • Schedule regular inspections to take care of problems as they arise.
  • 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 is comfortable.
  • When replacing part of your system, see if there are Energy Star-certified or other environmentally friendly options.
