Signs You May Need HVAC Repair or Replacement

An HVAC system that's not working properly or old likely needs professional attention for repairs or replacement. Watch for these indicators that your system needs service:

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

If you notice any of these HVAC red flags, your system evaluated. A local company can complete an inspection, diagnose problems, and recommend repairing or replacing your HVAC unit.

Cost of HVAC Installation and Maintenance in Key Largo

What you pay for HVAC installation or maintenance varies based on 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 control temperature, which all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions much like a standard split system, but is able to utilize either gas or electricity as energy sources.
  • Heat pump: Heat pumps transfer hot and cold air between your home and the outside. These systems don't make their own heat or AC, so they work better in milder climates and may not be as effective during Key Largo's hot summers.
  • Packaged heating and air: Packaged HVAC systems are a smart choice for smaller houses. They have a single cooling and heating unit, normally in a basement or attic. This unit is often space-saving, energy-efficient, and easy to maintain.

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

HVAC Unit TypeCost
Split$1,922-$4,899
Hybrid Split$3,894-$7,174
Heat Pump$3,015-$30,723
Packaged Heating and Air$252-$421

Ways to Save Money on HVAC Costs

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

  • Monitor for potential problems. Keeping an eye out for problems, for instance by consistently checking your thermostat and energy bills, allows you to resolve them before they get out of hand.
  • Change filters regularly. Changing or cleaning your air filters every 1–3 months helps air flow efficiently through your HVAC system. You should also try to prevent dirt and debris from building up around the outdoor sections of your system.
  • 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 reduces the amount of work your HVAC system must perform.
  • Keep your system clean. Keeping your grills, indoor evaporator coil, condenser fan blades, and ductwork clean helps your system function optimally and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system whenever it begins to look dirty.
ServiceCost
Filter Replacement$63-$168
Condensor Cleaning$1,262-$3,785
Thermostat Repair$84-$210
Ductwork Cleaning$404-$1,009

How To Choose a Local HVAC Company

Finding the right HVAC company is key for an easy installation or repair. Hiring an experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning year-round.

Compare Multiple Bids

Contact at least three HVAC providers for quotes. Explain the issues and have technicians visit to inspect your system if possible. Compare the contractors' explanations, solutions, estimated costs, warranties, and timeframes. Avoid companies that pressure you or demand payment upfront.

Check Credentials

When selecting an HVAC provider, choose one with technicians that have the proper training, licenses, and experience. HVAC contractors in all states 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." Contractors must pass an exam (the type of exam depends on what kind of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled at the state level.

HVAC contractors in Florida must be registered or certified with the Department of Business and Professional Regulation. Certified HVAC contractors must have four years of experience, pass an exam, and carry HVAC business insurance. Registered HVAC contractors may only work in one specific city, and the local government sets licensing requirements. You should also look at reviews and complaints on sites like Google Reviews, the Better Business Bureau (BBB), and Yelp. Choose a company with positive reviews and testimonials about fantastic customer experiences.

Understand Work Details

Always make sure you understand what a company’s process is like. When HVAC repairs are needed, ask your provider to list which parts require replacement and explain why. Confirm that your technician will clean and test the full system after finishing the work to guarantee proper operation. When replacing your HVAC system, ask the contractor to provide details on the new estimated installation time, features, brand, energy efficiency, and model. Before signing a contract, make sure you understand how your provider will properly size the new unit for your home and what the cost will be.

Compare Warranties

Trustworthy HVAC companies stand behind their services with warranties. Compare warranties from different companies, keeping in mind that broader coverage is better. Look for the provider that offers the most coverage for a reasonable price.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Key Largo, FL

You should have your HVAC system inspected approximately twice yearly. At the time of the inspection, your technician will tell you what services are required. 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.

Normally, you should have your HVAC system inspected 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 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 try to avoid making drastic changes in temperature all at once. Keep your roof in good shape and seal any door or window leaks to avoid letting cool air escape. Similarly, ensure that your attic is well ventilated to avoid trapping excess heat in your home.

It takes between one and three days to have your HVAC system installed or replaced. If you only need an air conditioning unit or a furnace, this can take anywhere from a few hours up to two days. This timeline will be affected by the size of your house, the accessibility of your system, and any new issues your technician uncovers.

For a 2,000-square-foot home, look for a furnace that's between 50,000 and 80,000 BTUs (British thermal units). In Key Largo, you may be able to make do with a furnace on the lower end of this range.

For a 2,000-square-foot home, you'll also want to look for an air conditioning unit with between 2.5 and 5 tons of capacity. In Key Largo, you'll likely want a unit on the higher end of this range. Typically, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.

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