Signs You May Need HVAC Repair or Replacement

An HVAC system that's not working properly or old likely needs professional attention for repairs or replacement. Watch for these indicators that your system needs service:

  • Temperature control issues or thermostat malfunctions
  • Refrigerant leaks
  • Unusually high energy bills
  • Cracking, rust, or corrosion
  • Poor air circulation or uneven heating/cooling
  • Frequent breakdowns and need for repairs
  • Odd noises when turning on
  • 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 Buffalo Grove

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

  • Split or mini-split: If your home lacks the right ductwork for central air or heating, you likely have a split HVAC system. Split or mini-split systems consist of indoor units that regulate the temperature in individual rooms, and that are all connected to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system works almost the same as a standard split system. It has the benefit of being able to utilize either electricity or gas for power.
  • Heat pump: Heat pumps move hot and cold air between your house and the outdoors. 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 often a good option for smaller houses. They consist of a single heating and cooling unit that's normally located in an attic or basement. This unit tends to be efficient, compact, and easy to maintain.

HVAC maintenance costs differ depending on what services are needed. HVAC systems are complex and can require different maintenance services. Fees for common services 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

Fixing your HVAC by repairing or replacing parts when needed is important, but can be expensive. Luckily, there are actions you can take to reduce gradual wear and tear on your system.

  • Change filters regularly. Changing or cleaning your air filters every 1–3 months helps air flow efficiently through your HVAC system. You should also try to prevent dirt and debris from building up around the outside areas of your system.
  • 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.
  • Keep your system clean. Cleaning your condenser fan blades, grills, ductwork, and indoor evaporator coil 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 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 the right things to look for in an HVAC company is key for a smooth installation or repair. Picking an established business with certified technicians gives you assurance your HVAC system will deliver consistent coolig and heating year-round.

Compare Multiple Bids

Contact at least three HVAC providers for quotes. Describe 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

Look for an HVAC company that employs skilled technicians who have the necessary licensure and training. In all states, HVAC contractors must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for all technicians 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 the type 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 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 check a company's reviews and complaints on sites such as Google Reviews, Yelp, and the Better Business Bureau (BBB). Pick a company with positive feedback and stories of satisfied customers.

Understand Work Details

Make sure you know the details of any project before it begins. When getting HVAC repairs, have your provider list which parts require replacement and why. Get confirmation that your technician will clean and test the entire system after the repair to ensure that everything works. When replacing your HVAC system, ask your installation company to provide details on the new brand, energy efficiency, features, model, and estimated installation time. Before signing a contract, make sure you understand how your provider will properly size the new unit 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. Review warranty details between providers and pick the one that offers the most comprehensive protection within your budget.

Get Quote in Writing

Always get HVAC bids in writing before work begins. A comprehensive quote covers costs for both materials and labor. Confirm that you agree to all terms before signing the contract.

Frequently Asked Questions About HVAC in Buffalo Grove, IL

You should have your HVAC system inspected twice a year. After completing their inspection, your technician will inform you if any services are needed. You should also have your system inspected if you start noticing issues such as strange noises, leaks, or unusual smells. If your home has ductwork, you should have it inspected every few years.

Usually, you should schedule inspections 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 likely sees 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. During all seasons, keep your thermostat as close to the outside temperature as you can, and try to adjust it only a few degrees at a time. You may also consider installing a smart thermostat.

It takes around one to three days to have an HVAC system installed or replaced. If you only need a furnace or a single air conditioning unit, this may take anywhere from a few hours up to two days. This timeline can be determined by the size of your home, the accessibility of your system, and any new issues your technician runs into.

For a 2,000-square-foot home, you'll need between 2.5 and 5 tons of air conditioning capacity. If your home is larger than 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).

Normally, HVAC financing is through a third-party lender. If your HVAC company doesn't offer financing, you could consider taking out a loan on your own. Be sure to speak with a financial advisor and your HVAC company to find out what options are available to you and appropriate for your situation.

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 on a regular basis.
  • Have regular inspections to take care of issues as they arise.
  • Keep your attic well-ventilated and make sure all doors and windows are well-sealed.
  • Install a smart thermostat. If you aren't able to purchase one, try keeping the temperature indoors as close to the outside temperature as you can.
  • When replacing part of your HVAC system, explore Energy Star-certified or other environmentally friendly options.
