Signs You May Need HVAC Repair or Replacement

If your HVAC system is broken or getting near the end of its lifespan, it likely needs servicing or replacement from an HVAC company. Watch for these signs your system needs service:

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

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

Cost of HVAC Installation and Maintenance in Oak Park

What you pay for 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 heating or air, you likely have a split HVAC system. Split or mini-split systems consist of interior units that control the temperature in individual rooms, and that are all connected to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system operates similar to a normal split system, but has the advantage of being able to draw power from either gas or electric sources.
  • Heat pump: Heat pumps move hot and cold air between your home and outside. These systems don't generate their own heat or AC, so they work more efficiently in moderate climates.
  • Packaged heating and air: Packaged HVAC systems work best in smaller houses. They consist of a single combined air conditioner and heating unit, usually located in an attic or basement. This unit is typically compact, cost-effective, and easy to maintain.

The cost of HVAC maintenance also varies depending on what kind of work you're having done. HVAC systems are complicated and might require different kinds of maintenance. The prices of some common jobs are as follows:

HVAC Unit Type Cost
Split $1,960-$4,995
Hybrid Split $3,971-$7,315
Heat Pump $3,074-$31,328
Packaged Heating and Air $257-$429

Ways to Save Money on HVAC Costs

It's important to fix or swap out your HVAC components when they become damaged, but it can also be expensive. Luckily, there are some steps you can take to reduce wear and tear on your system.

  • Change filters regularly. Replacing or cleaning your air filters every 30–90 days helps air flow efficiently through your system. You should also try to keep debris away from the external sections of your HVAC system as much as possible.
  • Keep your system clean. Cleaning your grills, indoor evaporator coil, condenser fan blades, and ductwork regularly helps your HVAC system work efficiently and lowers the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.
  • Change the position of your blinds seasonally. Keeping your blinds closed in the summer helps block out passive solar heat. Keeping them open in the winter helps you take advantage of this same heat. Both of these measures help reduce the frequency with which you need to run your HVAC.
  • Monitor for potential problems. Monitoring your system for problems — for example, by checking your thermostat and energy bills routinely — helps you get ahead of problems before they get too expensive.

Service Cost
Filter Replacement $64-$172
Condensor Cleaning $1,286-$3,859
Thermostat Repair $86-$214
Ductwork Cleaning $412-$1,029

How To Choose a Local HVAC Company

Finding the right HVAC company is key for a successful installation or repair. 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 companies for quotes. Describe the issues and have specialists visit to inspect your system if possible. Compare the companies' explanations, solutions, estimated costs, timeframes, and warranties. Avoid companies that pressure you or demand payment upfront.

Check Credentials

When looking for 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 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 confirm that your contractor meets all 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 the Better Business Bureau (BBB), Yelp, and Google Reviews. Pick a company with glowing feedback and good customer testimonials.

Understand Work Details

Always make sure you know the details of your project. When HVAC repairs are required, your provider should specify which parts require replacement and why. Confirm that your technician will clean and test the system after repairs are finished to ensure that it’s working properly. When replacing your HVAC, ask the contractor to describe the new features, brand, model, energy efficiency, and estimated installation time. Before work starts, ask how your provider plans to accurately size the unit for your home and how much it will cost.

Compare Warranties

Reliable HVAC companies provide warranties for their services. The broader the coverage, the better, so make sure to compare warranties between companies. Choose the one that offers the best coverage at a reasonable cost.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Oak Park, IL

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

Usually, it's best to have your HVAC system inspected in the spring and fall, as these times tend to be less busy. This also helps make sure your system is prepared for the summer and winter, when it likely sees the most use.

You can save energy throughout the year by reducing the amount of work it takes 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 avoid making drastic changes — adjust it only a few degrees at a time. You may also consider purchasing a smart thermostat.

It takes between one and three days to have an HVAC system installed or replaced. If you only need a furnace or a single air conditioning unit, this can take anywhere from a few hours up to two days. This timeline can be influenced by the size of your house, the accessibility of your system, and any issues your technician runs into.

For a 2,000-square-foot home, you'll need between 2.5 and 5 tons of air conditioning capacity. For homes over 1,000 square feet, central air is likely to be more effective for cooling than window units.

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

Usually, HVAC financing is through a third-party lender. If your HVAC company doesn't offer financing, you might consider taking out your own loan. Be sure to speak with a financial advisor and your HVAC company to learn what options are available and appropriate for your situation.

There are several ways you can make your HVAC system more energy-efficient:

  • Make sure your air ducts remain clean, and clean or change your air filters regularly.
  • Schedule regular inspections to take care of problems 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 don't want to or can't buy one, try to keep your inside temperature as close to the outside temperature as you can.
  • When you need to replace part of your HVAC system, see if there are Energy Star-certified or similar environmentally friendly options.
