Signs You May Need HVAC Repair or Replacement

If your HVAC system is having issues 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:

  • Frequent breakdowns and need for repairs
  • Strange noises when turning on
  • Corrosion, rust, or cracking
  • Refrigerant leaks
  • Temperature control issues or thermostat malfunctions
  • Unusually high energy bills
  • Poor air circulation or uneven heating/cooling
  • 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 diagnose problems and let you know whether repair or full HVAC replacement is required.

Cost of HVAC Installation and Maintenance in Bay St. Louis

The cost of HVAC installation or maintenance will differ depending on the type of unit you have. Common varieties of HVAC units include the following:

  • Split or mini-split: If your home lacks the right ductwork for central air or heating, you probably have a split HVAC system. Split or mini-split systems consist of interior units that regulate the temperature in individual rooms. These interior units are all connected to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system performs similarly to a standard split system, but is able to utilize either electricity or gas for power.
  • Heat pump: Heat pumps exchange warm and cold air between your home and the outdoors. They don't make their own heat or AC, so they perform best in temperate climates and may not be as effective during Bay St. Louis' hot summers.
  • Packaged heating and air: Packaged HVAC systems work well in smaller houses. They consist of a single combined air conditioner and heating unit, commonly located in a basement or attic. This unit is typically space-saving, cost-effective, and easy to maintain.

The amount you spend on HVAC maintenance also depends on the kind of work you're having done. HVAC systems are complicated and can require different kinds of maintenance. The cost of some common repairs is as follows:

HVAC Unit TypeCost
Split$1,703-$4,341
Hybrid Split$3,450-$6,356
Heat Pump$2,671-$27,221
Packaged Heating and Air$224-$373

Ways to Save Money on HVAC Costs

Repairing or replacing your HVAC system when needed is important, but can be costly. Luckily, there are steps you can take to reduce gradual wear and tear on your system.

  • Monitor for potential problems. Monitoring your system for problems — for example, by checking your thermostat and energy bills regularly — helps you get ahead of problems before they get too expensive.
  • 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 outdoor sections of your system.
  • 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 amount of work your HVAC system needs to do.
  • Keep your system clean. Regularly cleaning grills, condenser fan blades, indoor evaporator coil, and ductwork helps your HVAC system run efficiently and reduces the risk of mold. The National Air Duct Cleaners Association advises cleaning your HVAC system when it starts to look dirty.
ServiceCost
Filter Replacement$56-$149
Condensor Cleaning$1,118-$3,353
Thermostat Repair$75-$186
Ductwork Cleaning$358-$894

How To Choose a Local HVAC Company

It's important to know what makes a good HVAC company. A properly licensed contractor with the right experience will give you confidence that they can maintain your HVAC system properly, providing you with effective heating and cooling for your home.

Compare Multiple Bids

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

Check Credentials

When picking 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 mandatory for all technicians 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.

In Mississippi, HVAC contractors and subcontractors are required to be licensed by the Mississippi State Board of Contractors. To obtain this license, contractors must provide proof of general liability insurance, as well as workers' compensation insurance if they have above a certain number of employees. You should also look at a company's reviews and complaints on sites such as Yelp, the Better Business Bureau (BBB), and Google Reviews. Pick a company with great feedback and good customer testimonials.

Understand Work Details

It’s important to understand what the work process will look like. For HVAC repairs, the company should list the exact parts that need replacement and why. Confirm that your technician will clean and test your system afterward to make sure everything is operating properly. When replacing your HVAC system, ask the contractor to describe the new features, estimated installation time, brand, model, and energy efficiency. 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

Reliable HVAC companies offer warranties on service and installations. The more complete the coverage, the better. Review warranty details between companies and pick the one that provides the most comprehensive protection within your budget.

Get Quote in Writing

Always get HVAC quotes in writing before work begins. A thorough quote covers costs for both labor and materials. Confirm that you understand all terms before signing the contract.

Frequently Asked Questions About HVAC in Bay St. Louis, MS

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

Generally, you should schedule inspections in the spring and fall, as technicians tend to be less busy at these times. This also helps make sure your system is prepared for the summer and winter, when it typically sees the most use.

You can save energy during the summer by reducing the amount of power your HVAC system uses to keep your home cool. Set your thermostat as close to the outside temperature as you comfortably can, and avoid making drastic changes in temperature all at once. Keep your roof well-maintained and seal any door or window leaks to help keep cool air in. Similarly, make sure your attic is well ventilated to avoid trapping excess heat in your home.

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 might take between half a day and two days. This timeline can be determined by the size of your house, how easily accessible your system is, and any new 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. In Bay St. Louis, you'll probably want to explore units on the higher end of this range. For a house 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'll also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units). In Bay St. Louis, you might be able to make do with a lower-capacity furnace.

Your HVAC company may offer financing options via a third-party lender, or you may choose to obtain your own loan. It's a good idea to discuss payment options with a financial advisor and your HVAC company to make sure that you find the best option for you.

There are a number of 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.
  • Have regular inspections to take care of problems 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 your inside temperature as close to the outside temperature as you can.
  • When replacing part of your system, explore Energy Star-certified or similar environmentally friendly options.
