Signs You May Need HVAC Repair or Replacement

An HVAC system that's malfunctioning or past its lifespan likely needs professional attention for repairs or replacement. Watch for these signs that your system needs service:

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

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

Cost of HVAC Installation and Maintenance in Libertyville

The price of HVAC installation or maintenance will vary depending on the kind of unit you have. Common kinds of HVAC units include the following:

  • Split or mini-split: If your home doesn’t have the ductwork for central heating and cooling, you likely have a split or mini-split system instead. Split HVAC systems have interior units in each room to control temperature. These connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions comparably to a regular split system. It gives flexibility by providing the option to use either electricity or gas for energy.
  • Heat pump: Heat pumps circulate hot and cool air between your home and outside. They don't make their own heat or AC, so they work best in mild climates.
  • Packaged heating and air: Packaged HVAC systems are a great choice for smaller houses. They have a single cooling and heating unit, normally in an attic or basement. This unit is often space-saving, cost-effective, and easy to maintain.

HVAC maintenance costs differ depending on the particular service needed. HVAC systems are complicated and might require different kinds of maintenance. Fees for common services are as follows:

HVAC Unit Type Cost
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

It's important to take care of HVAC repairs and replacements in a timely manner, but it can also be expensive. Fortunately, there are steps you can take to reduce wear and tear on your system.

  • Monitor for potential problems. Monitoring the efficiency of your HVAC system — for instance by checking your thermostat settings and energy bills — helps you find and solve issues before they get too expensive.
  • Keep your system clean. Cleaning your indoor evaporator coil, ductwork, grills, and condenser fan blades regularly helps your HVAC system work efficiently and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.
  • Change filters regularly. Air flows through your HVAC system most effectively when you change out or clean the filters every 30–90 days. Also avoid letting debris pile up on the outside areas of your HVAC.
  • 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 is required to do.

Service Cost
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 indicators of a good HVAC company is important. A properly licensed contractor with the right experience will give you confidence that they can fix your system, providing you with effective air conditioning and heating for your home.

Compare Multiple Bids

Get quotes from three or more HVAC providers. Describe your issues and ask if specialists can inspect your system in person. Compare each contractor's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid providers that pressure you or demand payment before work.

Check Credentials

Look for an HVAC company that employs skilled technicians who have the necessary licensure and training. 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." An individual 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 by the state.

The state of Illinois doesn't have state-level licensing requirements for contractors. However, there may be local regulations, so make sure to check with your municipal government to verify that your contractor meets all 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 company with great reviews and reports of positive experiences from customers.

Understand Work Details

It’s important to know what the work process is going to look like. For HVAC repairs, the company should detail the exact parts that need replacement and why. Confirm that your technician will clean and test your system afterward to ensure proper functioning. When replacing your HVAC, ask your contractor to provide details on the new energy efficiency, estimated installation time, model, features, and brand. Before signing a contract, make sure you understand the process your provider will use to select the correctly sized system for your home and what the cost will be.

Compare Warranties

Reliable HVAC companies provide warranties for their work. Broader coverage is better, so make sure to review warranties between providers. 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. A comprehensive quote should cover both materials and labor. Make sure you agree to all terms before signing a contract.

Frequently Asked Questions About HVAC in Libertyville, IL

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

Normally, it's smart to have your HVAC system inspected in the spring and fall, as these times tend to be less busy. 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 reducing the amount of power your HVAC system uses to maintain your home's temperature. Always keep your thermostat as close to the outside temperature as you can, and avoid making drastic changes — adjust it only a few degrees at once. You may also consider getting a smart thermostat.

It takes roughly one to three days to have an HVAC system installed or replaced. If you only need an air conditioning unit or a furnace, this can take between half a day and two days. This timeline can be influenced by the size of your home, how easily accessible your system is, and any issues your technician uncovers.

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 an air conditioning unit with between 2.5 and 5 tons of capacity. In general, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.

Your HVAC company might offer financing options through a third-party lender, or you may be able 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 your air ducts clean and change or clean your air filters on a regular basis.
  • 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 don't want to or can't buy one, try keeping your inside temperature as close to the outside temperature as is comfortable.
  • When it comes time to replace any part of your system, explore Energy Star-certified or other environmentally friendly options.
