Signs You May Need HVAC Repair or Replacement

If your HVAC system is broken or getting old, it likely needs servicing or replacement from an HVAC company. Look for these signs your system needs service:

  • Unusually high energy bills
  • Odd noises when the system turns on
  • Rust, cracking, or corrosion
  • Frequent breakdowns and need for repairs
  • Poor air circulation or uneven heating/cooling
  • Temperature control issues or thermostat malfunctions
  • Refrigerant leaks
  • 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 diagnose problems and decide whether repairing or getting a new HVAC unit is the best solution.

Cost of HVAC Installation and Maintenance in Harrisburg

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

  • Split or mini-split: Homes without ductwork for centralized climate control often have split or mini-split HVAC systems. These systems consist of indoor units in each room to control temperature. These indoor units connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system performs similarly to a standard split system, but is able to utilize either electricity or gas for power.
  • Heat pump: Heat pumps exchange warm and cool air between your home and outside. They don't make their own heating and cooling, so they work more effectively in more mild climates.
  • Packaged heating and air: Packaged HVAC systems are a smart choice for smaller houses. They have a single cooling and heating unit, typically in an attic or basement. This unit is often compact, energy-efficient, and easy to maintain.

HVAC maintenance costs vary depending on what services are needed. HVAC systems are complicated and may require different kinds of maintenance. Costs for common services are as follows:

HVAC Unit Type Cost
Split $1,933-$4,928
Hybrid Split $3,917-$7,216
Heat Pump $3,033-$30,903
Packaged Heating and Air $254-$423

Ways to Save Money on HVAC Costs

HVAC system repairs and replacements are important, but can be pricey. Luckily, homeowners can take steps to reduce wear and tear on their HVAC and lower future maintenance needs.

  • 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.
  • Change filters regularly. Replacing or cleaning your air filters every 30–90 days helps air flow efficiently through your system. Also try to keep debris away from the external sections of your HVAC system as much as possible.
  • Change the position of your blinds seasonally. During winter, leave your blinds open so your home benefits from passive solar heat. In summer, keep blinds shut to block out heat. Doing both lowers the amount of work your HVAC system must perform.
  • Keep your system clean. Regularly cleaning grills, ductwork, condenser fan blades, and indoor evaporator coil helps keep your HVAC system running efficiently and reduces the risk of mold. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.

Service Cost
Filter Replacement $63-$169
Condensor Cleaning $1,269-$3,807
Thermostat Repair $85-$211
Ductwork Cleaning $406-$1,015

How To Choose a Local HVAC Company

Knowing the indicators of a reliable HVAC company is key for a smooth repair or installation. 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 three or more HVAC companies. Describe your issues and ask if technicians can inspect your system in person. Compare each company's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid companies that pressure you or demand payment before work.

Check Credentials

It's important to choose an HVAC company that employs technicians with the appropriate qualifications and expertise. In all states, HVAC contractors have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, a contractor must pass an exam (the specific exam depends on what kind of equipment they plan to work with). Section 608 certification is required for all technicians who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." All other licensing requirements are handled at the state level.

Illinois doesn't have state-level contractor licensing requirements. However, there may be local regulations. Be sure to check with your municipal government to verify that your contractor meets all the requirements. You can also verify an Illinois business license on the Secretary of State's website. You should also read reviews and complaints on sites like Yelp, Google Reviews, and the Better Business Bureau (BBB). Pick a company with positive reviews and testimonials about great customer experiences.

Understand Work Details

It’s important to know what the work process will look like. For HVAC repairs, the company should list the specific parts that need replacement and why. Confirm that your technician will clean and test the full system afterward to guarantee everything is working correctly. When replacing your HVAC, request that the company explain the new energy efficiency, brand, model, estimated installation time, and features. Before signing a contract, 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. Broader coverage is better, so make sure to compare warranties between providers. Choose the one that provides the most comprehensive coverage at a fair cost.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Harrisburg, IL

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

The best times of the year to have your HVAC system inspected are the spring and fall. Technicians are less busy during these times, making it easier to get an appointment. This also helps get your system ready for the summer and winter, which is when it normally gets 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. Always keep your thermostat as close to the outside temperature as you can, and try to adjust it only a few degrees at once. You might also consider a smart thermostat.

It takes around one to three days to have your HVAC system installed or replaced. If you only need a furnace or a single air conditioning unit, this can take between half a day and two days. This timeline can be determined 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, you should look for around 2.5 to 5 tons of air conditioning capacity. For homes over 1,000 square feet, central air will generally be more effective than window units for cooling.

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

Your HVAC company might offer financing options through a third-party lender, or you might choose 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're choosing the best option for you.
