Signs You May Need HVAC Repair or Replacement

If your HVAC system is broken or getting near the end of its lifespan, it likely needs servicing or replacement from an HVAC company. Watch for these indicators your system needs service:

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

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

Cost of HVAC Installation and Maintenance in Woodstock

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

  • Split or mini-split: If your home doesn’t have the ductwork for central heating and cooling, you likely have a split or mini-split system instead. Split HVAC systems have internal units in each room to manage temperature. These connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system operates similar to a normal split system, but has the advantage of being able to draw power from either electric or gas sources.
  • Heat pump: Heat pumps move hot and cold air between your home and outside. These systems don't make their own heat or AC, so they work more effectively in moderate climates.
  • Packaged heating and air: Packaged HVAC systems are a good choice for smaller houses. They have a single heating and cooling unit, usually in an attic or basement. This unit is often small, energy-efficient, and easy to maintain.

HVAC maintenance prices differ based on the specific services needed. HVAC systems can be complicated and potentially require several different services. Price ranges for typical jobs 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

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

  • 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 outdoor parts of your HVAC.
  • Monitor for potential problems. Monitoring the efficiency of your HVAC system — for instance by checking your thermostat settings and energy bills — helps you identify and fix problems before they get out of hand.
  • Change the position of your blinds seasonally. Leaving your blinds open during the colder months helps warm your home with passive solar heating. Closing the blinds during the summer helps prevent the same heat from getting inside. Doing both helps minimize the demand on your HVAC system.
  • Keep your system clean. Regularly cleaning indoor evaporator coil, grills, ductwork, and condenser fan blades helps keep your HVAC system running efficiently and reduces the risk of mold. The National Air Duct Cleaners Association recommends cleaning your heating and cooling system when it starts to look dirty.
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 the indicators of a good HVAC company is important. Working with a contractor that's properly licensed and highly experienced will give you confidence that they can maintain your HVAC system properly, providing you with effective air conditioning and heating for your home.

Compare Multiple Bids

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

Check Credentials

When picking an HVAC provider, choose one with technicians that have the proper training, licenses, and experience. HVAC contractors in all states need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory 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 the type 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 confirm that your contractor meets all of the requirements. You can also verify an Illinois business license on the Secretary of State's website. Checking reviews on Google Reviews, the Better Business Bureau (BBB), Yelp, and similar sites can aid your decision as well. Choose a provider with great reviews and stories of positive experiences from customers.

Understand Work Details

Always make sure you understand the details of any project. For HVAC repairs, your provider should detail which parts require replacement and why. Confirm that your technician will clean and test your system after repairs are finished to verify that it’s working properly. When replacing your HVAC system, ask the contractor to describe the new estimated installation time, model, energy efficiency, brand, and features. Before work starts, ask how your provider plans to accurately size the unit for your home and how much it will cost.

Compare Warranties

Good HVAC companies offer warranties on repairs and installations. The more complete the coverage, the better. Review warranty details between providers and pick the one that offers the most comprehensive protection for the fairest price.

Get Quote in Writing

Get a written quote before HVAC work begins. A full 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 Woodstock, IL

Generally, your HVAC system should be inspected twice a year. After an inspection, your HVAC technician will tell you what services are required. You should also call a technician if you notice any new issues, like unusual smells, leaks, or strange noises. If you have ductwork in your home, 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 less busy during these times, making it easier to get an appointment. This also helps get your system ready for the summer and winter, the times of the year when it gets 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 is comfortable, and avoid making drastic changes — adjust it only a few degrees at once. You may also consider installing a smart thermostat.

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

For a 2,000-square-foot home, you'll also want an air conditioning unit with between 2.5 and 5 tons of capacity. In general, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.

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

There are several ways you can make your HVAC system more energy-efficient:

  • Make sure your air ducts remain clean, and change or clean your air filters regularly.
  • Schedule regular inspections to take care of issues 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 is comfortable.
  • When it comes time to replace any part of your HVAC system, see if there are Energy Star-certified or other environmentally friendly options.
