Signs You May Need HVAC Repair or Replacement

If your HVAC system is broken or getting near the end of its lifespan, it likely needs servicing or replacement from an HVAC company. Watch for these indicators your system needs service:

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

If you see any of these HVAC issues, we recommend having a technician inspect your system. A local professional can diagnose problems and let you know whether whether fixing or replacing your HVAC unit is the best solution.

Cost of HVAC Installation and Maintenance in Johnstown

HVAC installation or maintenance costs change depending on your system. Common HVAC unit varieties include the following:

  • Split or mini-split: If your home lacks the right ductwork for central heating or air, you likely have a split HVAC system. Split or mini-split systems consist of interior units that regulate the temperature in individual rooms, and that are all connected 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 having the capability to use either gas or electricity 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. They may not be as effective during Johnstown's cold winters.
  • Packaged heating and air: Packaged HVAC systems are a smart choice for smaller houses. These systems have a single heating and cooling unit, normally located in an attic or basement. They're compact, energy-efficient, and easy to maintain.

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

HVAC Unit TypeCost
Split$1,772-$4,518
Hybrid Split$3,591-$6,615
Heat Pump$2,780-$28,331
Packaged Heating and Air$233-$388

Ways to Save Money on HVAC Costs

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

  • Monitor for potential problems. Keeping an eye out for problems, for instance by routinely checking your thermostat and energy bills, lets you resolve them before they get too expensive.
  • Keep your system clean. Regularly cleaning ductwork, indoor evaporator coil, grills, and condenser fan blades helps your HVAC system run efficiently and reduces the risk of mold. The National Air Duct Cleaners Association advises cleaning your system when it starts to look dirty.
  • Change filters regularly. Changing or cleaning your air filters every 1–3 months helps air flow smoothly through your HVAC system. You should also try to prevent dirt and debris from building up around the outside areas of your system.
  • Change the position of your blinds seasonally. Opening your blinds in winter allows passive solar heat into your house. Closing your blinds in summer blocks some heat from getting indoors. Both of these measures help lower the work required from your house's HVAC system.
ServiceCost
Filter Replacement$58-$155
Condensor Cleaning$1,163-$3,490
Thermostat Repair$78-$194
Ductwork Cleaning$372-$931

How To Choose a Local HVAC Company

Knowing the indicators of a reliable HVAC company is key for a smooth installation or repair. Established providers with certified technicians can offer assurance your HVAC system will deliver consistent heating and cooling year-round.

Compare Multiple Bids

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

Check Credentials

Choose an HVAC company with skilled technicians who have appropriate licensing and experience. HVAC contractors in all states have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, contractors must pass an exam (the type of 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 at the state level.

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 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. Checking reviews on the Better Business Bureau (BBB), Google Reviews, Yelp, and similar sites can help your decision. Choose a company with great reviews and stories of positive experiences from customers.

Understand Work Details

It’s important to know what the work process will look like. For HVAC repairs, the company should detail the specific 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 provider to explain the new energy efficiency, estimated installation time, features, model, and brand. Before signing paperwork, make sure you understand the process your provider will use to size the new HVAC system appropriately for your home and what the price will be.

Compare Warranties

A reputable HVAC company will back its repair work and installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully review the fine print for each contractor and choose the company that provides the best protection at a reasonable price.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Johnstown, NY

You should have your HVAC system inspected approximately twice a year. After the inspection, your technician will tell you what services are needed. You should also have your system inspected if you notice new issues such as strange noises, unusual smells, or leaks. If your home has ductwork, you should have it inspected every few years.

Normally, you should 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 during the winter by reducing the amount of work your HVAC system needs to do to heat your home. Keep your thermostat as low as is comfortable and avoid making drastic changes in the temperature — only increase or decrease it a few degrees at a time. If possible, try switching to a smart thermostat.

It takes between one and three days to have your HVAC system installed or replaced. If you only need a furnace or a single air conditioning unit, this may take between half a day and two days. This timeline can be influenced by the size of your home, how easily accessible your system is, and any issues your technician discovers.

For a 2,000-square-foot home, try to purchase a furnace that's between 50,000 and 80,000 BTUs (British thermal units). In Johnstown, you'll probably want a furnace on the higher end of (or even above) this range.

For a 2,000-square-foot home, you'll also want to purchase an air conditioning unit with around 2.5 to 5 tons of capacity. In Johnstown, a unit with a lower capacity may be sufficient. Typically, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.

Your HVAC company might have financing options via a third-party lender, or you may be able 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're choosing the best option for you.

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

  • Make sure your air ducts remain clean, and change or clean your air filters on a regular basis.
  • Have regular inspections to take care of problems as they arise.
  • Make sure your doors and windows are well-sealed and keep your attic well-ventilated.
  • Install a smart thermostat. If you don't want to or can't buy one, try keeping your inside temperature as close to the outside temperature as you can.
  • When you need to replace part of your system, see if there are Energy Star-certified or other environmentally friendly options.
