Signs You May Need HVAC Repair or Replacement

An HVAC system that's malfunctioning or outdated likely needs professional attention for repairs or replacement. Watch for these signals that your system needs service:

  • Odd noises when turning on
  • Corrosion, cracking, or rust
  • Poor air circulation or uneven heating/cooling
  • Thermostat malfunctions or temperature control issues
  • Frequent breakdowns and need for repairs
  • Higher than normal energy bills
  • 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 pinpoint problems and recommend whether repair or full HVAC replacement is required.

Cost of HVAC Installation and Maintenance in Selden

The price of HVAC installation or maintenance will differ depending on the kind of unit you have. Common varieties of HVAC units 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 interior units in each room to regulate temperature. These indoor units 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 exchange hot and cold air between your home and the outdoors. They don't generate their own heating and cooling, so they work more effectively in more temperate climates.
  • Packaged heating and air: Packaged HVAC systems are a smart choice for smaller homes. These systems have a single combined AC and heating, normally located in a basement or attic. They're space-saving, energy-efficient, and easy to maintain.

HVAC maintenance costs vary depending on what services are needed. HVAC systems are complicated and may require different maintenance services. Fees for some common services 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

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

  • Change filters regularly. Replacing or cleaning your air filters every 1–3 months helps air flow smoothly through your system. Also try to keep debris away from the external sections of your HVAC system as much as possible.
  • Change the position of your blinds seasonally. Closing your blinds in the summer blocks some passive solar heat from getting indoors. Opening the blinds in the winter allows this same heat to help warm your home. Both of these measures help lower the work required from your HVAC system.
  • Keep your system clean. Keeping your indoor evaporator coil, grills, ductwork, and condenser fan blades clean helps your system function optimally and reduces the chance 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 regularly — helps you catch issues 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 what to look for in an HVAC company is important for a successful project. Partnering with an experienced, licensed contractor can give you peace of mind and ensure your system provides reliable heating and air conditioning for your home.

Compare Multiple Bids

Request estimates from three or more HVAC providers. Explain your issues and ask if technicians can inspect your system in person. Review each contractor's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid providers that pressure you or demand payment before work.

Check Credentials

Look for an HVAC company that employs qualified technicians with 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 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 by the state.

The state of New York doesn't have state-level HVAC licensing. However, there may be local requirements, so be sure to check with your city or municipal government. For example, in some cases, a technician may need an Oil Burning Equipment Installer or High Pressure Boiler Operating Engineer license from the NYC Department of Buildings, or a Certificate of Qualification for Refrigerating System Operating Engineer from the Fire Department of New York. You should also look at reviews and complaints on sites like the Better Business Bureau (BBB), Google Reviews, and Yelp. Pick 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 getting HVAC repairs, ask your provider to list which parts require replacement and why. Confirm that your technician will clean and test your system after finishing the work to ensure proper operation. When replacing your HVAC system, ask your contractor to provide details on the new energy efficiency, brand, features, model, and estimated installation time. Before signing a contract, make sure you understand the process your provider will use to select the correctly sized system for your home and what the cost will be.

Compare Warranties

A reputable HVAC company will back its repair services and installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully review warranty terms for each contractor and choose the provider that offers the most protection within your budget.

Get Quote in Writing

Always get estimates for HVAC service in writing before committing to a provider. An itemized quote should cover both labor and materials. Make sure you agree to all terms before signing a contract.

Frequently Asked Questions About HVAC in Selden, NY

Normally, you should have your HVAC system inspected twice a year. After that inspection, your technician will tell you what, if any, services are needed. You should also have an inspection if you notice any new issues, like strange noises, leaks, or unusual smells. If you have ductwork in your home, it should be serviced every few years.

The best times to have your HVAC system inspected are during the spring and fall. Technicians tend to be less busy during these times, which makes it easier to get an appointment. This also ensures that your system is ready for the summer and winter, the times of the year when it sees the most use.

You can save energy throughout the year by reducing the amount of work it takes for your HVAC system to maintain the temperature of your home. During all seasons, keep your thermostat as close to the outside temperature as possible, and avoid making drastic changes — adjust it only a few degrees at a time. You may also consider getting a smart thermostat.

It takes around one to three days to have your HVAC system installed or replaced. If you need just an air conditioning unit or a furnace, this can take between half a day and 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, 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 to purchase an air conditioning unit with between 2.5 and 5 tons of capacity. Usually, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.

There are a number of ways you can make your HVAC system more energy-efficient:

  • Keep ductwork clean, and change or clean your air filters regularly.
  • Have regular inspections to take care of issues 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 aren't able to purchase one, try keeping your inside temperature as close to the outside temperature as is comfortable.
  • When you need to replace part of your HVAC system, explore Energy Star-certified or other environmentally friendly options.
