Signs You May Need HVAC Repair or Replacement

A malfunctioning or aging HVAC system probably needs attention from a professional who can make fixes or install a new unit. Watch out for these common indicators that your HVAC needs service:

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

Arrange an inspection if you notice any of these problems. A local technician can inspect your system, identify problems, and determine whether you need to fix or replace your HVAC.

Cost of HVAC Installation and Maintenance in Buffalo Grove

The price of HVAC installation or maintenance changes depending on the kind of unit you have. Common types of HVAC units include the following:

  • Split or mini-split: Homes without ductwork for central heating and cooling often have split or mini-split HVAC systems. These systems consist of internal units in each room to control temperature, which all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions comparably to a regular split system. It provides flexibility by having the option to use either electricity or gas for energy.
  • Heat pump: Heat pumps move warm and cool air between your home and outside. These systems don't make their own heat or AC, so they work more effectively in milder climates.
  • Packaged heating and air: Packaged HVAC systems work best in smaller homes. They consist of a single combined air conditioner and heating unit, commonly located in a basement or attic. This unit is typically compact, energy-efficient, and straightforward to maintain.

HVAC maintenance costs vary based on the specific services needed. HVAC systems can be complex and potentially require a number of services. Costs for typical jobs are as follows:

HVAC Unit TypeCost
Split$1,973-$5,030
Hybrid Split$3,998-$7,366
Heat Pump$3,096-$31,544
Packaged Heating and Air$259-$432

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. Fortunately, there are steps you can take to slow the wear and tear on your HVAC.

  • Change filters regularly. Air flows through your HVAC system most effectively when you replace or clean the filters every 30–90 days. Also try not to let debris pile up on the external sections of your HVAC.
  • Monitor for potential problems. Keeping an eye out for problems, for instance by consistently checking your thermostat and energy bills, lets you resolve them before they get too expensive.
  • Keep your system clean. Cleaning your condenser fan blades, grills, indoor evaporator coil, and ductwork regularly helps your HVAC system work efficiently and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system once it starts to look dirty.
  • 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 lower the work required from your home’s HVAC system.
ServiceCost
Filter Replacement$65-$173
Condensor Cleaning$1,295-$3,886
Thermostat Repair$86-$216
Ductwork Cleaning$414-$1,036

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 heating and air conditioning for your home.

Compare Multiple Bids

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

Check Credentials

Choose an HVAC company with well-trained technicians who have appropriate licensing and experience. HVAC contractors in all states have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, an individual must pass an exam (the type of exam depends on the 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 verify an Illinois business license on the Secretary of State's website. You should also look at reviews and complaints on sites like Google Reviews, Yelp, and the Better Business Bureau (BBB). Pick a company with glowing reviews and testimonials about great customer experiences.

Understand Work Details

Always make sure you know the details of any project. For HVAC repairs, your provider should list 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, ask the provider to explain the new energy efficiency, model, brand, features, and estimated installation time. Before signing a contract, be sure you understand the process your provider will use to size the new HVAC system appropriately 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 companies. Choose the one that provides the most comprehensive coverage at a reasonable cost.

Get Quote in Writing

Get written estimates before beginning any HVAC work. The quote should outline costs for both materials and labor. Review all terms carefully before signing.

Frequently Asked Questions About HVAC in Buffalo Grove, IL

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

Usually, it's smart to have your HVAC system inspected in the spring and fall, as technicians tend to be less busy at these times. This also helps get your system ready for the summer and winter, when it probably sees the most use.

You can save energy throughout the year by making it easier for your HVAC system to maintain the temperature of your home. Always 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 could also consider a smart thermostat.

Generally, whole-system HVAC installation or replacement takes between one and three days. 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 be based on things like the size of your home, how easily accessible different parts of the system are, and whether your technician discovers any problems.

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

There are a number of ways you can make your HVAC system more energy-efficient:

  • Keep ductwork clean, and clean or change your air filters regularly.
  • Have regular inspections to take care of issues as they come up.
  • Keep your attic well-ventilated and make sure all doors and windows are well-sealed.
  • Install a smart thermostat. If you don't want to or can't buy one, try keeping the temperature indoors as close to the outside temperature as is comfortable.
  • When replacing part of your system, see if there are Energy Star-certified or similar environmentally friendly options.
