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 repairs or replacement from an HVAC company. Watch for these signs your system needs service:

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

These HVAC red flags indicate that you should have your system evaluated. A local technician can complete an inspection, diagnose problems, and recommend repairing or replacing your HVAC unit.

Cost of HVAC Installation and Maintenance in Hazelwood

HVAC installation or maintenance prices change depending on your system. Common HVAC unit types include the following:

  • Split or mini-split: If your home's ductwork can't accommodate a central HVAC system, you probably have a split or mini-split system. Split systems have interior units in each room to control temperature; these indoor units all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC unit operates similarly 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 transfer hot and cold air between your house and outside. They don't create their own heating and cooling, so they work more efficiently in more mild climates.
  • Packaged heating and air: Packaged HVAC systems work well in smaller homes. They consist of a single combined air conditioner and heating unit, typically located in an attic or basement. This unit is typically compact, cost-effective, and easy to maintain.

HVAC maintenance prices vary based on the work needed. HVAC systems are complicated and may need several types of maintenance. Costs for common jobs are as follows:

HVAC Unit Type Cost
Split $1,987-$5,064
Hybrid Split $4,025-$7,416
Heat Pump $3,117-$31,760
Packaged Heating and Air $261-$435

Ways to Save Money on HVAC Costs

Fixing your HVAC by repairing or replacing parts when needed is important, but can be costly. Luckily, there are steps you can take to slow the wear and tear on your system.

  • Keep your system clean. Cleaning your indoor evaporator coil, ductwork, condenser fan blades, and grills regularly helps your HVAC system work efficiently and lowers the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.
  • Change the position of your blinds seasonally. During winter, leave your blinds open so your home benefits from passive solar heat. In summer, keep blinds shut to block out heat. Doing both helps minimize the amount of work your HVAC system must perform.
  • Monitor for potential problems. Keeping an eye out for problems, for instance by routinely checking your thermostat and energy bills, lets you resolve them before they get too expensive.
  • Change filters regularly. Replacing or cleaning your air filters every 1–3 months helps air flow smoothly through your system. Also try to keep debris away from the external sections of your HVAC system as much as possible.

Service Cost
Filter Replacement $65-$174
Condensor Cleaning $1,304-$3,912
Thermostat Repair $87-$217
Ductwork Cleaning $417-$1,043

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is important for a successful project. Look for an experienced, licensed contractor that can give you peace of mind and make sure your system provides reliable heating and air conditioning for your home.

Compare Multiple Bids

Contact at least three HVAC providers for quotes. Describe your issues and schedule an in-person inspection if possible. Compare contractors' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid providers that pressure you or demand upfront payment.

Check Credentials

When looking for an HVAC company, choose one with technicians that have the proper training, licenses, and experience. In all states, HVAC contractors need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for any individual who helps "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 HVAC technicians in Missouri; however, most municipalities have local requirements. It's important 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. Always check a company's reviews and complaints with organizations such as the Better Business Bureau (BBB), Google Reviews, and Yelp. You want to hire a provider with glowing reviews and stories of positive service experiences.

Understand Work Details

Make sure you know the details of any project before starting. If HVAC repairs are required, have your provider detail which parts require replacement and why. Confirm that your technician will clean and test the entire system after the repair to ensure that everything works. When getting a replacement, ask your contractor to explain the new HVAC system estimated installation time, brand, model, features, and energy efficiency. Before starting the project, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

Trustworthy HVAC companies provide warranties for their services. The broader the coverage, the better, so make sure to review warranties between providers. Choose the one that provides the most comprehensive coverage at a fair cost.

Get Quote in Writing

Get written quotes before starting any HVAC work. The quote should include costs for both labor and materials. Review all terms carefully before signing.

Frequently Asked Questions About HVAC in Hazelwood, MO

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

Generally, it's a good idea to schedule inspections in the spring and fall, as these times tend to be less busy. This also helps get your system ready for the summer and winter, when it typically sees the most use.

You can save energy throughout the year by making it easier for your HVAC system to maintain your home's temperature. During all seasons, keep your thermostat as close to the outside temperature as is comfortable, and try to adjust it only a few degrees at once. You could also consider installing a smart thermostat.

Generally, whole-system HVAC installation or replacement takes between one and three days. Installing or replacing an air conditioning unit or a furnace can take as little as half a day or as much as two days. The exact amount of time will be based on factors like the size of your home, how easily accessible different sections 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. If your home is larger than 1,000 square feet, central air will usually be more effective for cooling than window units.

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

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