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. Keep an eye out for these common indicators that your HVAC needs service:

  • Unusually high energy bills
  • Temperature control issues or thermostat malfunctions
  • Strange noises when the system turns on
  • Refrigerant leaks
  • Rust, corrosion, or cracking
  • Poor air circulation or uneven heating/cooling
  • Frequent breakdowns and need for repairs
  • An HVAC system that's over 15 years old

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

Cost of HVAC Installation and Maintenance in Washington

What you pay for HVAC installation or maintenance is determined by your system style. Common HVAC unit styles 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 internal units in each room to regulate temperature, which all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions much like a standard split system, but has the capacity to draw on either electricity or gas for power.
  • Heat pump: Heat pumps exchange hot and cold air between your home and the 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 smart choice for smaller houses. They have a single heating and cooling unit, usually in an attic or basement. This unit is often space-saving, energy-efficient, 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 TypeCost
Split$1,779-$4,535
Hybrid Split$3,604-$6,641
Heat Pump$2,791-$28,439
Packaged Heating and Air$234-$389

Ways to Save Money on HVAC Costs

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

  • Change filters regularly. Air flows most effectively through your HVAC system when you change out or clean the filters every 1–3 months. Also try not to let debris pile up on the outside areas of your HVAC.
  • Monitor for potential problems. Monitor your system for issues, for example by routinely checking your thermostat and energy bills. This enables you to address issues before they get too expensive.
  • Keep your system clean. Keeping your indoor evaporator coil, ductwork, condenser fan blades, 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. Closing your blinds in the summer blocks some passive solar heat from getting indoors. Opening the blinds in the winter allows this same heat to help warm your home. Both of these measures help lower the work required from your home’s HVAC system.
ServiceCost
Filter Replacement$58-$156
Condensor Cleaning$1,168-$3,503
Thermostat Repair$78-$195
Ductwork Cleaning$374-$934

How To Choose a Local HVAC Company

Knowing the indicators of a good HVAC company is important. A properly licensed contractor with the right experience will give you confidence that they can maintain your HVAC system properly, providing you with effective air conditioning and heating in your home.

Compare Multiple Bids

Contact at least three HVAC providers for quotes. Describe the issues and have technicians visit to inspect your HVAC system if possible. Compare the providers' 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 training and licenses. HVAC contractors in all states must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for all technicians 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 at the state level.

There are no state-level licensing requirements for HVAC technicians in Missouri; however, most municipalities have local requirements. Be sure to check with your local government to understand requirements for licenses like HVAC Contractor or HVAC Journeyman Contractor. You can also verify that a company holds a valid business license. You should also check reviews and complaints on sites like Google Reviews, the Better Business Bureau (BBB), and Yelp. Pick a company with positive reviews and reports of good customer experiences.

Understand Work Details

Always make sure you know what a company’s process is like. When getting HVAC repairs, ask your provider to explain which parts need replacement and why. Confirm that your technician will clean and test the system at the end of the job to guarantee proper operation. When replacing your HVAC system, have the provider describe the new estimated installation time, model, features, energy efficiency, and brand. Before signing a contract, ask how your provider plans to accurately size the unit for your home and how much it will cost.

Compare Warranties

Trustworthy HVAC companies provide warranties for their work. Broader coverage is better, so make sure to review warranties between providers. Choose the one that provides the most comprehensive coverage at a reasonable cost.

Get Quote in Writing

Always get quotes for HVAC service in writing before work begins. A comprehensive quote should cover both labor and materials. Make sure you agree to all terms before signing a contract.

Frequently Asked Questions About HVAC in Washington, MO

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

Usually, it's a good idea to schedule inspections 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 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. 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 a time. You might also consider a smart thermostat.

Generally, HVAC installation or replacement takes one to three days for the entire system. Installing or replacing an air conditioning unit or a furnace takes anywhere from about half a day up to two days. The exact amount of time will depend on things like the size of your house, how easily accessible different areas are, and whether your technician finds any problems.

For a 2,000-square-foot home, look for 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 around 2.5 to 5 tons of capacity. Usually, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.

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 keeping the temperature indoors as close to the outside temperature as you can.
  • When you need to replace part of your HVAC system, explore Energy Star-certified or other environmentally friendly options.
