Signs You May Need HVAC Repair or Replacement

An HVAC system that's broken or outdated likely needs professional attention for maintenance or replacement.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

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

These HVAC red flags indicate that you should have your system evaluated. A local technician can complete an inspection, diagnose problems, and advise you whether you should repair or replace your HVAC unit.

Cost of HVAC Installation and Maintenance in Smithtown

Your HVAC installation or maintenance cost fluctuates depending on the style of unit. Common HVAC unit types include the following:

  • Split or mini-split: If your home's ductwork isn’t suited for a central HVAC system, you probably have a split or mini-split system. Split systems have indoor units in each room to regulate temperature. These indoor units all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions very similarly to a standard split system. It has the advantage of being able to utilize either gas or electricity for power.
  • 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.
  • Packaged heating and air: Packaged HVAC systems are more popular in smaller homes. These systems consist of a single heating and cooling unit, typically located in an attic or basement. This unit tends to be efficient, compact, and easy to maintain.

HVAC maintenance costs vary depending on what services are needed. HVAC systems are complex and might 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

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

  • Change filters regularly. Cleaning or replacing 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.
  • Monitor for potential problems. Monitor your system for issues, for example by routinely checking your thermostat and energy bills. This allows you to address problems before they get out of hand.
  • Change the position of your blinds seasonally. During winter, leaving your blinds open allows your home to benefit from passive solar heating. In the summer, keeping your blinds shut helps to block out heat. Doing both lowers the amount of work your HVAC system needs to do.
  • Keep your system clean. Keeping your ductwork, grills, indoor evaporator coil, and condenser fan blades clean enables your HVAC system to function effectively and lowers your risk of mold. The National Air Duct Cleaners Association recommends cleaning your home's HVAC when you notice things starting to get dirty.
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

It's important to know what makes a good HVAC company. Working with a contractor that's properly licensed and highly experienced will give you confidence that they can keep your system running efficiently, providing you with effective air conditioning and heating for your home.

Compare Multiple Bids

Contact at least three HVAC contractors for quotes. Describe your issues and schedule an in-person inspection if possible. Compare providers' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid providers that pressure you or demand upfront payment.

Check Credentials

Choose an HVAC company with well-trained technicians who have proper licensing and experience. In all states, HVAC contractors have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, an individual must pass an exam (the specific exam depends on the kind of equipment they intend to work with). Section 608 certification is required for all technicians who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." All other licensing requirements are handled on a state-by-state basis.

There is no state-level HVAC licensing in New York. 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 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. Also look at a company's reviews and complaints on sites such as Yelp, Google Reviews, and the Better Business Bureau (BBB). Pick a company with glowing feedback and good customer testimonials.

Understand Work Details

Always make sure you know what a company’s process looks like. When HVAC repairs are needed, ask your provider to specify which parts need replacement and why. Confirm that your technician will clean and test your system at the end of the job to guarantee proper operation. When replacing your HVAC system, ask the installation company to provide details on the new estimated installation time, energy efficiency, features, brand, and model. Before work begins, 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 trustworthy HVAC company will stand behind its repair work and installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully compare the fine print between contractors and choose the company that provides the most protection at a reasonable price.

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 understand all terms before signing a contract.

Frequently Asked Questions About HVAC in Smithtown, NY

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

Usually, it's a good idea to 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 probably 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. Always keep your thermostat as close to the outside temperature as is comfortable, and avoid making drastic changes — adjust it only a few degrees at a time. You may also consider getting a smart thermostat.

It takes roughly one to three days to have an HVAC system installed or replaced. If you need just a furnace or a single air conditioning unit, this might take between half a day and two days. This timeline can be influenced by the size of your home, the accessibility of your system, and any issues your technician uncovers.

For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. For a house over 1,000 square feet, central air will be more effective for cooling than window units.

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).

There are several ways you can make your HVAC system more energy-efficient:

  • Keep ductwork clean, and clean or change your air filters regularly.
  • Schedule regular inspections to take care of problems as they arise.
  • Keep your attic well-ventilated and make sure all doors and windows are well-sealed.
  • Install a smart thermostat. If you don't want to or can't buy one, try keeping the temperature indoors as close to the outside temperature as is comfortable.
  • When replacing part of your HVAC system, see if there are Energy Star-certified or similar environmentally friendly options.
