Signs You May Need HVAC Repair or Replacement

If your home's HVAC system is malfunctioning or getting old, you may need to hire an HVAC contractor for maintenance or replacement. Look for these common signs that your system needs professional attention:

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

If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can diagnose problems and let you know whether repair or full HVAC replacement is the best course of action.

Cost of HVAC Installation and Maintenance in Port Jefferson

What you spend on 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 often have split or mini-split HVAC systems. These systems consist of internal units in each room to regulate temperature, which all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system works almost the same as a standard split system. It has the benefit of being able to utilize either electricity or gas for power.
  • Heat pump: Heat pumps work by circulating 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 houses. These systems consist of a single heating and cooling unit, normally located in an attic or basement. This unit tends to be efficient, compact, and easy to maintain.

HVAC maintenance prices vary based on the specific services needed. HVAC systems can be complex and potentially require several different services. Price ranges for typical jobs are as follows:

HVAC Unit TypeCost
Split$1,948-$4,966
Hybrid Split$3,947-$7,272
Heat Pump$3,056-$31,141
Packaged Heating and Air$256-$426

Ways to Save Money on HVAC Costs

It's important to repair or replace your HVAC system when it's broken, but it can also be expensive. Luckily, there are some steps you can take to slow the wear and tear on your system.

  • Change filters regularly. Cleaning or replacing your air filters every 1–3 months helps air flow efficiently through your system. You should also try to keep debris away from the outside areas of your HVAC system as much as possible.
  • Change the position of your blinds seasonally. Keeping your blinds closed in the summer helps block out passive solar heat. Keeping them open in the winter helps you take advantage of this same heat. Both of these measures help reduce the amount of work your HVAC system needs to do.
  • Keep your system clean. Cleaning your indoor evaporator coil, ductwork, condenser fan blades, and grills regularly helps your HVAC system work efficiently and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system once it begins to look dirty.
  • Monitor for potential problems. Keep an eye on your system for issues, for example by routinely checking your thermostat and energy bills. This enables you to address problems before they get too expensive.
ServiceCost
Filter Replacement$64-$170
Condensor Cleaning$1,279-$3,836
Thermostat Repair$85-$213
Ductwork Cleaning$409-$1,023

How To Choose a Local HVAC Company

Knowing the indicators of a good HVAC company is important. A properly licensed contractor with the right experience will give you confidence that they can maintain your HVAC system properly, providing you with effective air conditioning and heating in your home.

Compare Multiple Bids

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

Check Credentials

When hiring an HVAC company, 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 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 what kind of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled by the state.

The state of New York doesn't have state-level HVAC licensing; however, many cities and municipalities have their own requirements, so be sure to check with your local government. For example, in some cases, a technician may need a High Pressure Boiler Operating Engineer or Oil Burning Equipment Installer license from the NYC Department of Buildings, or a Certificate of Qualification for Refrigerating System Operating Engineer from the Fire Department of New York. Always check a company's reviews and complaints with organizations such as the Better Business Bureau (BBB), Google Reviews, and Yelp. Choose a provider with positive reviews and a history of good customer service.

Understand Work Details

It’s important to understand what the work process will look like. For HVAC repairs, the company should list the particular 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, have the provider describe the new model, estimated installation time, brand, energy efficiency, and features. Before work starts, ask how your provider plans to accurately size the unit for your home and how much it will cost.

Compare Warranties

A trustworthy HVAC company will back its repair services and equipment 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 best protection at a reasonable price.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Port Jefferson, NY

You should have your HVAC system inspected twice yearly. 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 leaks, strange noises, or unusual smells. If your system has ductwork, it should be inspected every few years.

Usually, it's best to 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 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 avoid making drastic changes — adjust it only a few degrees at once. You might also consider installing a smart thermostat.

It takes roughly one to three days to have your HVAC system installed or replaced. If you need just 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 runs into.

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

For a 2,000-square-foot home, you'll also want an air conditioning unit with between 2.5 and 5 tons of capacity. Generally, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.

Typically, HVAC financing is through a third-party lender. If your HVAC company doesn't offer financing, you might consider taking out your own loan. Be sure to speak with a financial advisor and your HVAC company to find out what options are available and appropriate for your situation.
