Signs You May Need HVAC Repair or Replacement

An HVAC system that's malfunctioning or past its lifespan likely needs professional attention for maintenance or replacement. Watch for these signs that your system needs service:

  • Frequent breakdowns and need for repairs
  • Odd noises when the system turns on
  • Unusually high energy bills
  • Poor air circulation or uneven heating/cooling
  • Refrigerant leaks
  • Rust, cracking, or corrosion
  • Temperature control issues or thermostat malfunctions
  • 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, identify problems, and advise you whether you should repair or replace your HVAC unit.

Cost of HVAC Installation and Maintenance in Montgomery

Your HVAC installation or maintenance cost varies depending on the type 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 functions comparably to a regular split system. It provides flexibility by providing the option to draw on either electricity or gas for energy.
  • Heat pump: Heat pumps work by transferring hot and cold air between your home and the outdoors. These systems don't generate heat or air conditioning themselves, and are better for more moderate climates.
  • Packaged heating and air: Packaged HVAC systems are good for smaller houses. Packaged systems consist of a single heating and cooling unit that's typically located in an attic or basement. This unit tends to be efficient, compact, and easy to maintain.

The price of HVAC maintenance also varies depending on what kind of work being done. HVAC systems are complex and may require different kinds of maintenance. The cost of some common repairs is as follows:

HVAC Unit TypeCost
Split$1,985-$5,060
Hybrid Split$4,022-$7,409
Heat Pump$3,114-$31,731
Packaged Heating and Air$261-$434

Ways to Save Money on HVAC Costs

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

  • Keep your system clean. Keeping your condenser fan blades, indoor evaporator coil, ductwork, and grills clean enables your HVAC system to function properly and lowers your risk of mold. The National Air Duct Cleaners Association suggests cleaning your HVAC when you notice things starting to get dirty.
  • Change the position of your blinds seasonally. Leaving your blinds open during the winter allows passive solar heating to warm your home. Closing the blinds in warmer seasons helps prevent the same heat from getting inside. Doing both helps lessen the strain on your HVAC.
  • 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 identify and fix problems before they get out of hand.
  • Change filters regularly. Cleaning or replacing your air filters every 1–3 months helps air flow smoothly through your system. Also try to keep debris away from the outdoor portions of your HVAC system as much as possible.
ServiceCost
Filter Replacement$65-$174
Condensor Cleaning$1,303-$3,909
Thermostat Repair$87-$217
Ductwork Cleaning$417-$1,042

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. Established providers with certified technicians can offer assurance your HVAC system will deliver consistent heating and cooling year-round.

Compare Multiple Bids

Contact at least three HVAC providers for quotes. Explain the issues and have specialists visit to inspect your HVAC 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 selecting an HVAC provider, choose one with technicians that have the appropriate training, licenses, and experience. In all states, HVAC contractors must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for all contractors who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." Contractors 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.

The state of Illinois doesn't have state-level licensing requirements for contractors. However, there may be local regulations. Be sure to check with your municipal government to confirm 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 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

Always make sure you understand what a company’s process looks like. When getting HVAC repairs, ask your provider to explain which parts require replacement and explain why. Confirm that your technician will clean and test your system afterward to ensure proper operation. When getting a replacement, ask your contractor to explain the new HVAC system brand, model, estimated installation time, energy efficiency, and features. Before starting the project, you should understand the process your provider will use to properly size the system for your home and the price you'll pay.

Compare Warranties

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

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Montgomery, IL

You should have your HVAC system inspected about twice annually. At the time of the inspection, your technician will inform you if any services are needed. You should also call a technician if you start noticing issues such as leaks, unusual smells, or strange noises. If your system has ductwork, it should be inspected every few years.

Normally, it's best to have your HVAC system inspected in the spring and fall, as these times tend to be less busy. This also helps make sure your system is prepared for the summer and winter, when it probably 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 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 a smart thermostat.

For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. If your home is larger than 1,000 square feet, central air will generally be more effective for cooling than window units.

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 via a third-party lender, or you might choose to obtain a loan on your own. 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.

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

  • Keep ductwork clean, and change or clean your air filters regularly.
  • Schedule regular inspections to take care of problems as they arise.
  • 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 replacing part of your system, explore Energy Star-certified or similar environmentally friendly options.
