Signs You May Need HVAC Repair or Replacement

If your home's HVAC system isn't working correctly or nearing the end of its lifespan, you might need an HVAC contractor for maintenance or replacement. Watch for these common indicators that your system needs expert attention:

  • Odd noises when the system turns on
  • Frequent breakdowns and need for repairs
  • Uneven heating/cooling or poor air circulation
  • Refrigerant leaks
  • Higher than normal energy bills
  • Temperature control issues or thermostat malfunctions
  • Cracking, rust, or corrosion
  • An HVAC system that's over 15 years old

Schedule an inspection if you notice any of these problems. A local technician can evaluate your system, detect problems, and figure out whether you need to fix or replace your HVAC.

Cost of HVAC Installation and Maintenance in Westchester

The price of HVAC installation or maintenance will vary depending on the type 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 air or heating, you likely have a split or mini-split system instead. Split HVAC systems have internal units in each room to regulate temperature. These connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions very similarly to a standard split system. It has the advantage of being able to utilize either gas or electricity for power.
  • Heat pump: Heat pumps exchange 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 more temperate climates.
  • Packaged heating and air: Packaged HVAC systems are often a good option for smaller houses. Packaged systems consist of a single combined heating and cooling unit that's normally located in an attic or basement. This unit tends to be compact, efficient, and easy to maintain.

HVAC maintenance prices vary based on the specific services needed. HVAC systems can be complicated and potentially require several different services. Fees for typical jobs are as follows:

HVAC Unit TypeCost
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 complete repairs or full-system HVAC replacements as needed, though they can be expensive. The good news is that homeowners have ways to reduce gradual wear and tear and reduce the frequency of breakdowns.

  • Change the position of your blinds seasonally. Opening your blinds in winter allows passive solar heat into your house. Closing your blinds in summer blocks some heat from getting indoors. Both of these measures help decrease the work required from your HVAC system.
  • Keep your system clean. Cleaning your grills, ductwork, indoor evaporator coil, and condenser fan blades regularly helps keep your HVAC system working efficiently and lowers the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system once it begins to look dirty.
  • Monitor for potential problems. Monitoring your system for problems — for example, by checking your thermostat and energy bills routinely — helps you catch issues before they get too expensive.
  • Change filters regularly. Changing or cleaning your air filters every 30–90 days helps air flow smoothly through your HVAC system. We also recommend regularly clearing dirt and debris away from the outside areas of your system.
ServiceCost
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

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 heating and air conditioning for your home.

Compare Multiple Bids

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

Check Credentials

When selecting an HVAC provider, choose one with technicians that have the right training, licenses, and experience. In all states, HVAC contractors need to 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 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 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 Yelp, the Better Business Bureau (BBB), and Google Reviews. Pick a company with positive feedback and stories of satisfied customers.

Understand Work Details

Always make sure you know what a company’s process is like. When getting HVAC repairs, ask your provider to list which parts require replacement and explain why. Confirm that your technician will clean and test your system afterward to ensure proper operation. For replacement, ask your contractor to explain the new HVAC system energy efficiency, features, brand, estimated installation time, and model. Before signing a contract, 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 back its repair work and installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully compare the fine print between contractors and choose the provider that offers the greatest protection at a reasonable price.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Westchester, IL

You should have your HVAC system inspected about twice a year. Following an inspection, your technician will inform 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.

Generally, it's a good idea 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 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 might also consider installing a smart thermostat.

Generally, whole-system HVAC installation or replacement takes one to three days. Installing or replacing a furnace or air conditioning unit takes anywhere from about half a day up to two days. The exact amount of time will be based on factors like how large your home is, how easily accessible different parts of the system are, and whether your technician finds any problems.

For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. For a house over 1,000 square feet, central air will usually be more effective than window units for cooling.

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).

Your HVAC company might provide financing options via a third-party lender, or you might be able to obtain your own loan. 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.

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 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 keeping your inside temperature as close to the outside temperature as you can.
  • When it comes time to replace any part of your HVAC system, explore Energy Star-certified or similar environmentally friendly options.
