Signs You May Need HVAC Repair or Replacement

An HVAC system that's broken or old likely needs professional attention for maintenance or replacement. Watch for these signals that your system needs service:

  • Refrigerant leaks
  • Strange noises when turning on
  • Frequent breakdowns and need for repairs
  • Poor air circulation or uneven heating/cooling
  • Cracking, rust, or corrosion
  • Temperature control issues or thermostat malfunctions
  • Unusually high 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 diagnose problems and determine whether repair or full HVAC replacement is the better solution.

Cost of HVAC Installation and Maintenance in Diamondhead

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 central air often 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 in the same way as a normal split system, but has the advantage of being able to draw power from either electric or gas sources.
  • Heat pump: Heat pumps work by transferring hot and cold air between your home and the outdoors. These systems don't create heat or air conditioning themselves, and are more suited to more moderate climates. They may not be as effective during Diamondhead's hot summers.
  • 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 small, cost-effective, and easy to maintain.

HVAC maintenance costs vary based on the specific services needed. HVAC systems can be complex and potentially require several different services. Fees for typical jobs are 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

HVAC system repairs and replacements are important, but can be expensive. Fortunately, there are steps homeowners can take to reduce wear and tear on their system and lower future maintenance needs.

  • Keep your system clean. Regularly cleaning indoor evaporator coil, ductwork, grills, and condenser fan blades helps your HVAC system run efficiently and reduces the risk of mold. The National Air Duct Cleaners Association recommends cleaning your system when it starts to look dirty.
  • Change filters regularly. Switching out or cleaning your air filters every 30–90 days helps air flow efficiently through your HVAC system. You should also try to prevent dirt and debris from building up around the external parts of your system.
  • Change the position of your blinds seasonally. Leaving your blinds open during the colder months 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 demand on your HVAC system.
  • Monitor for potential problems. Keeping an eye out for problems, for instance by routinely checking your thermostat and energy bills, helps you resolve them before they get out of hand.
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 keep your system running efficiently, providing you with effective heating and cooling in 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 companies that pressure you or demand upfront payment.

Check Credentials

Look for an HVAC company that employs skilled technicians who have the necessary licensure and training. In all states, HVAC contractors must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for any individual who helps "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.

HVAC contractors and subcontractors in Mississippi are required to be licensed by the Mississippi State Board of Contractors. To obtain this license, contractors must show proof of general liability insurance. They must also have workers' compensation insurance if they have above a certain number of employees. You should also read reviews and complaints on sites like Google Reviews, Yelp, and the Better Business Bureau (BBB). Pick a company with glowing reviews and testimonials about fantastic customer experiences.

Understand Work Details

It’s important to know what the work process will look like. For HVAC repairs, the company should detail the particular parts that need replacement and why. Confirm that your technician will clean and test the full system afterward to make sure everything is operating properly. When replacing your HVAC, have the contractor explain the new estimated installation time, model, features, energy efficiency, and brand. Before signing paperwork, be sure you understand how your provider will determine the right system size for your home and what the price will be.

Compare Warranties

A reputable HVAC company will back its repair work and installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully compare the fine print between contractors and choose the provider that offers the greatest protection within your budget.

Get Quote in Writing

Get written estimates before starting HVAC work. The quote should cover costs for both labor and materials. Read all terms carefully before signing.

Frequently Asked Questions About HVAC in Diamondhead, MS

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

Generally, 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 get your system ready for the summer and winter, when it probably sees the most use.

You can save energy during the summer by making it easier for your HVAC system to keep your home cool. Set your thermostat as close to the outside temperature as is comfortable, and avoid making drastic changes in temperature all at once. Keep your roof well-maintained and seal any leaks around your windows and doors 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 an HVAC system installed or replaced. If you need just an air conditioning unit or a furnace, this may take anywhere from a few hours up to two days. This timeline will be influenced by the size of your home, 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 Diamondhead, you'll probably want to choose a unit that's on the higher end of this range. For homes over 1,000 square feet, central air will be more effective than window units for cooling.

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). In Diamondhead, you might be able to make do with a lower-capacity furnace.

Your HVAC company might offer financing options via a third-party lender, or you might be able 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're choosing 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.
  • Schedule regular inspections to take care of issues as they arise.
  • Make sure your doors and windows are well-sealed and keep your attic well-ventilated.
  • Install a smart thermostat. If you aren't able to purchase one, try keeping the temperature indoors as close to the outside temperature as is comfortable.
  • When you need to replace part of your HVAC system, see if there are Energy Star-certified or similar environmentally friendly options.
