Signs You May Need HVAC Repair or Replacement

If your home's HVAC system is malfunctioning or nearing the end of its lifespan, you might need an HVAC contractor for repairs or replacement. Watch for these common signs that your system requires expert attention:

  • Frequent breakdowns and need for repairs
  • Refrigerant leaks
  • Poor air circulation or uneven heating/cooling
  • Odd noises when the system turns on
  • Temperature control issues or thermostat malfunctions
  • Corrosion, rust, or cracking
  • Higher than normal energy bills
  • 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 Grafton

Your HVAC installation or maintenance cost changes depending on the style of unit. Common HVAC unit varieties include the following:

  • Split or mini-split: Homes without ductwork for centralized climate control frequently have split or mini-split HVAC systems. These systems consist of indoor units in each room to control temperature, which all 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 draw power from either gas or electric sources.
  • Heat pump: Heat pumps exchange warm and cold air between your home and outside. They don't produce their own heat or AC, so they perform best in temperate climates.
  • Packaged heating and air: Packaged HVAC systems are a good choice for smaller homes. These systems have a single heating and cooling unit, typically located in a basement or attic. They're space-saving, cost-effective, and easy to maintain.

HVAC expenses vary based on the work needed. HVAC systems are complicated and may need several types of maintenance. Prices for common jobs are as follows:

HVAC Unit Type Cost
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

Taking care of necessary HVAC repairs and replacements when needed is crucial, but can be costly. Luckily, there are steps you can take to reduce gradual wear and tear on your system.

  • Keep your system clean. Keeping your ductwork, grills, condenser fan blades, and indoor evaporator coil clean enables your HVAC system to function properly and lowers the risk of mold. The National Air Duct Cleaners Association suggests cleaning your HVAC when you notice it starting to get dirty.
  • Change filters regularly. Air flows through your HVAC system most effectively when you replace or clean the filters every 30–90 days. Also avoid letting debris pile up on the outdoor parts of your HVAC.
  • 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 amount of work your HVAC system needs to do.
  • Monitor for potential problems. Keeping a close eye on the efficiency of your HVAC system — for instance by reviewing your thermostat settings and energy bills — helps you find and solve issues before they get too expensive.

Service Cost
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 makes a trustworthy HVAC company is vital for a smooth installation or repair. Hiring an experienced, credentialed HVAC contractor gives you confidence your system can provide reliable heating and air conditioning year-round.

Compare Multiple Bids

Get quotes from at least three HVAC contractors. Describe your issues and ask if specialists can inspect your system in person. Review each company's diagnoses, recommended solutions, estimated cost, warranties, and timelines. Avoid contractors that pressure you or demand payment before work.

Check Credentials

Look for an HVAC company that employs qualified technicians who have the necessary training and licenses. 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 at the state level.

There are no state-level licensing requirements for contractors in Illinois. However, there may be local regulations, so make sure to check with your municipal government to verify 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 check a provider's reviews and complaints with organizations such as the Better Business Bureau (BBB), Yelp, and Google Reviews. You'll want to select a provider with positive reviews and a history of good customer service.

Understand Work Details

Always make sure you know the details of any project. When HVAC repairs are required, your provider should detail which parts require replacement and why. Confirm that your technician will clean and test the full system after repairs are finished to ensure that it’s working properly. When replacing your HVAC, ask the installation company to provide details on the new estimated installation time, model, brand, features, and energy efficiency. Before work begins, 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 offer warranties on repairs and equipment installations. The more complete the coverage, the better. Compare warranty details between companies and pick the one that offers the most comprehensive protection for the fairest price.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Grafton, IL

Normally, your HVAC system should be inspected twice a year. After that inspection, your HVAC technician will tell you what services are needed. You should also have an inspection if you notice any new issues, such as unusual smells, leaks, or strange noises. 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 during the spring and fall. Technicians are often less busy during these times, which makes it easier to get an appointment. This also helps get your system ready for the summer and winter, when it typically sees the most use.

You can save energy throughout the year by making it easier for your HVAC system 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 a time. You might also consider getting a smart thermostat.

Generally, HVAC installation or replacement takes between one and three days for the entire system. Installing or replacing a furnace or air conditioning unit may take anywhere from a few hours up to two days. The exact amount of time will vary depending on things 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 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 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 these options, you may consider taking out a loan on your own. Be sure to talk to a financial advisor and your HVAC company to find out what options are available and appropriate for your situation.

There are a number of 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.
  • 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 to keep the temperature indoors as close to the outside temperature as you can.
  • When it comes time to replace any part of your system, explore Energy Star-certified or other environmentally friendly options.
