Signs You May Need HVAC Repair or Replacement

If your home's HVAC system isn't working correctly or suffering from a lot of wear and tear, you may need to hire an HVAC contractor for repairs or replacement. Look for these common indicators that your system requires expert attention:

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

If you notice any of these HVAC red flags, your system evaluated. A local company can complete an inspection, diagnose problems, and advise you whether you should repair or replace your HVAC unit.

Cost of HVAC Installation and Maintenance in Greenwood

What you spend on HVAC installation or maintenance depends on your system style. Common HVAC unit styles include the following:

  • Split or mini-split: Homes without ductwork for central air often have split or mini-split HVAC systems. These systems consist of internal units in each room to control temperature. These indoor units connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system operates similar to a normal split system, but has the benefit of being able to utilize energy from either gas or electric sources.
  • Heat pump: Heat pumps circulate warm and cold air between your home and the outdoors. They don't generate their own heat or AC, so they work best in moderate climates.
  • Packaged heating and air: Packaged HVAC systems are good for smaller houses. They consist of a single combined heating and cooling unit, normally located in an attic or basement. This unit tends to be compact, efficient, and easy to maintain.

HVAC maintenance prices differ depending on what services are needed. HVAC systems are complicated and may require different maintenance services. Prices for some common services are as follows:

HVAC Unit TypeCost
Split$1,932-$4,924
Hybrid Split$3,914-$7,211
Heat Pump$3,031-$30,881
Packaged Heating and Air$254-$423

Ways to Save Money on HVAC Costs

Repairing or replacing your HVAC system when needed is crucial, but can be costly. Fortunately, there are actions you can take to reduce gradual wear and tear on your system.

  • 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 reduce the strain on your HVAC system.
  • Change filters regularly. Replacing your air filters or washing them every 30–90 days 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 indoor evaporator coil, ductwork, condenser fan blades, and grills helps keep your HVAC system running efficiently and lowers your risk of mold. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.
  • Monitor for potential problems. Monitor your system for issues, for example by routinely checking your thermostat and energy bills. This allows you to address issues before they get out of hand.
ServiceCost
Filter Replacement$63-$169
Condensor Cleaning$1,268-$3,804
Thermostat Repair$85-$211
Ductwork Cleaning$406-$1,014

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is crucial for a successful project. Look for an experienced, licensed contractor that 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 contractors for quotes. Describe your issues and schedule an in-person inspection if possible. Compare contractors' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid providers that pressure you or demand upfront payment.

Check Credentials

When picking an HVAC company, 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 required for all contractors who "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.

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 also verify an Illinois business license on the Secretary of State's website. You should also look at a company's reviews and complaints on sites such as the Better Business Bureau (BBB), Google Reviews, and Yelp. Pick a company with great feedback and good customer testimonials.

Understand Work Details

Always make sure you know the details of a planned project. For HVAC repairs, your provider should specify which parts need replacement and why. Confirm that your technician will clean and test the system after repairs are done to ensure that it’s working properly. When replacing your HVAC, have the contractor explain the new estimated installation time, brand, model, energy efficiency, and features. 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 provide warranties for their work. The broader the coverage, the better, so make sure to review warranties between companies. Choose the one that offers the best coverage at a fair cost.

Get Quote in Writing

Always get HVAC estimates in writing before work begins. A thorough quote will cover costs for both labor and materials. Make sure that you agree to all terms before signing the contract.

Frequently Asked Questions About HVAC in Greenwood, IL

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

Normally, 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 make sure your system is prepared 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. Always 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 a smart thermostat.

Generally, whole-system HVAC installation or replacement takes one to three days. Installing or replacing an air conditioning unit or a furnace may take anywhere from a few hours up to two days. The exact amount of time will depend on factors like how large your home is, how easily accessible different sections are, and whether your technician finds any problems.

For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. If your home is larger than 1,000 square feet, central air will usually 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).

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 a financial advisor and your HVAC company to make sure that you find the best option for you.
