Signs You May Need HVAC Repair or Replacement

A faulty or aging HVAC system probably needs professional attention from a technician who can make fixes or install a new unit. Look out for these common signs that your HVAC needs service:

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

If you notice any of the above, have a local HVAC technician inspect your system. They can identify problems and let you know whether repair or full HVAC replacement is needed.

Cost of HVAC Installation and Maintenance in Florissant

What you spend on HVAC installation or maintenance depends on your system style. Common HVAC unit styles include the following:

  • Split or mini-split: If your home lacks the ductwork for central air or heating, you probably have a split or mini-split system instead. Split HVAC systems have interior units in each room to regulate temperature. These 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 moving warm and cool air between your home and the outdoors. These systems don't generate heat or air conditioning themselves, and are more suited to more moderate climates.
  • Packaged heating and air: Packaged HVAC systems are often a good option for smaller homes. They consist of a single combined heating and cooling unit, typically located in an attic or basement. This unit tends to be compact, efficient, and easy to maintain.

HVAC maintenance costs vary depending on what services are needed. HVAC systems are complex and can require different kinds of maintenance. Prices for some common services 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

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.

  • Change the position of your blinds seasonally. Keeping your blinds open in the winter helps you take advantage of passive solar heating. Keeping them closed in the summer helps keep some of this heat out. Both of these measures help reduce the frequency with which you need to run your HVAC.
  • Change filters regularly. Replacing or cleaning your air filters every 1–3 months helps air flow smoothly through your HVAC system. We also recommend regularly clearing dirt and debris away from the outside areas of your system.
  • Keep your system clean. Keeping your grills, indoor evaporator coil, ductwork, and condenser fan blades clean helps your system function optimally and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends that you clean your HVAC system when it starts to look dirty.
  • Monitor for potential problems. Monitoring your system for issues — for example, by checking your thermostat and energy bills routinely — helps you catch issues before they get too expensive.

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 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

Request estimates from at least three HVAC contractors. Explain your issues and ask if specialists can inspect your system in person. Review each company's diagnoses, recommended solutions, estimated cost, timelines, and warranties. Avoid companies that pressure you or demand payment before work.

Check Credentials

Choose an HVAC company with highly trained technicians who have proper licensing and experience. HVAC contractors in all states have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, individuals must pass an exam (the specific exam depends on what kind of equipment they intend to work with). Section 608 certification is required for all technicians who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." All other licensing requirements are handled on a state-by-state basis.

Missouri doesn't have state-level licensing requirements for HVAC contractors; however, most municipalities have local requirements. Make sure that you check with your local government to understand requirements for licenses such as HVAC Contractor or HVAC Journeyman Contractor. You can also check that a company holds a valid business license. Always check a provider's reviews and complaints with organizations such as the Better Business Bureau (BBB), Google Reviews, and Yelp. You'll want to select a company with positive reviews and a history of good customer service.

Understand Work Details

Make sure you understand the details of any project before starting. When getting HVAC repairs, have your provider detail which parts require replacement and why. Get confirmation that your technician will clean and test your system after the repair to ensure that everything works. When replacing your HVAC, request that the company explain the new energy efficiency, estimated installation time, features, brand, and model. Before signing paperwork, make sure you understand the process your provider will use to size the new HVAC system appropriately for your home and what the price will be.

Compare Warranties

Trustworthy HVAC companies back their services with warranties. Compare warranties from different companies, while remembering that broader coverage is better. Look for the provider that offers the most coverage for a reasonable price.

Get Quote in Writing

Get a written estimate before HVAC work starts. A full quote includes both labor and material costs. Make sure you understand and agree to all terms before signing the contract.

Frequently Asked Questions About HVAC in Florissant, MO

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

Generally, it's smart 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 probably 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 you can, and avoid making drastic changes — adjust it only a few degrees at once. You may also consider getting a smart thermostat.

It takes roughly one to three days to have your HVAC system installed or replaced. If you only need a furnace or a single air conditioning unit, this can take between half a day and two days. This timeline will be affected by the size of your house, the accessibility of your system, and any issues your technician discovers.

For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. For homes over 1,000 square feet, central air will generally 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 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 talk to your HVAC company and a financial advisor to find out what options are available to you and appropriate for your situation.
