Signs You May Need HVAC Repair or Replacement

If your HVAC system is faulty or getting old, it likely needs repairs or replacement from an HVAC company. Look for these indicators your system needs service:

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

Cost of HVAC Installation and Maintenance in Holtsville

The cost of HVAC installation or maintenance varies depending on the kind of unit you have. Common types 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 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 benefit of being able to utilize energy from either gas or electric sources.
  • Heat pump: Heat pumps transfer warm and cool air between your home and outside. These systems don't produce their own heat or AC, so they work more effectively in more temperate climates.
  • Packaged heating and air: Packaged HVAC systems are often a good option for smaller houses. They consist of a single heating and cooling unit, usually located in a basement or attic. This unit tends to be compact, efficient, and easy to maintain.

HVAC maintenance prices differ depending on the particular service needed. HVAC systems are complex and can require different maintenance services. Costs 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

Fixing your HVAC by repairing or replacing parts when needed is crucial, but can be expensive. Luckily, there are steps you can take to minimize wear and tear over time on your system.

  • Change filters regularly. Air flows most effectively through your HVAC system when you change out or clean the filters every 1–3 months. Also try not to let debris pile up on the external sections of your HVAC.
  • Keep your system clean. Regularly cleaning grills, ductwork, indoor evaporator coil, and condenser fan blades helps your HVAC system run efficiently and reduces your risk of mold. The National Air Duct Cleaners Association recommends cleaning your system when it starts to look dirty.
  • Monitor for potential problems. Keeping an eye out for problems, for instance by consistently checking your thermostat and energy bills, helps you resolve them before they get too expensive.
  • 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 needs to do.
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

Finding the right HVAC company is crucial for an easy installation or repair. 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 companies for quotes. Describe your issues and schedule an in-person inspection if possible. Compare providers' 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. 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.

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 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 check a provider's reviews and complaints with organizations such as the Better Business Bureau (BBB), Google Reviews, and Yelp. Look for a a company with glowing reviews and stories of positive service experiences.

Understand Work Details

It’s important to understand 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 ensure proper functioning. When replacing your HVAC, ask the contractor to provide details on the new estimated installation time, brand, model, energy efficiency, and features. 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

Reliable HVAC companies offer warranties on repairs and installations. The more complete the coverage, the better. Review warranty details between providers and pick the one that offers the most comprehensive protection for a fair price.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Holtsville, NY

Generally, you should have your HVAC system inspected twice a year. After that inspection, your technician will tell you what services are required. You should also call a technician if you start to notice any issues, like strange noises, unusual smells, or leaks. If your home has ductwork, it should be serviced every few years.

The best times of the year to have your HVAC system inspected are during the spring and fall. Technicians are often less busy during these times, so it will be easier to get an appointment. This also ensures that your system is ready for the summer and winter, which is when it normally gets 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 try to adjust it only a few degrees at once. You might 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 anywhere from a few hours up to two days. This timeline will be affected by the size of your home, the accessibility of your system, and any new issues your technician runs into.

For a 2,000-square-foot home, you'll need between 2.5 and 5 tons of air conditioning capacity. If your home is larger than 1,000 square feet, central air will be more effective for cooling than window units.

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

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

  • Keep your air ducts clean and change or clean your air filters regularly.
  • Schedule regular inspections to take care of issues 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 to keep your inside temperature as close to the outside temperature as you can.
  • When it comes time to replace any part of your HVAC system, explore Energy Star-certified or similar environmentally friendly options.
