Signs You May Need HVAC Repair or Replacement

A malfunctioning or aging HVAC system probably needs attention from a professional who can make fixes or install a new unit. Watch out for these common signs that your HVAC needs service:

  • Higher than normal energy bills
  • Frequent breakdowns and need for repairs
  • Strange noises when the system turns on
  • Thermostat malfunctions or temperature control issues
  • Uneven heating/cooling or poor air circulation
  • Refrigerant leaks
  • Corrosion, rust, or cracking
  • 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 Williston

Your HVAC installation or maintenance cost fluctuates depending on the style of unit. Common HVAC unit varieties 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 interior units in each room to regulate temperature, which all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system performs similarly to a standard split system, but is able to utilize either gas or electricity as energy sources.
  • Heat pump: Heat pumps exchange 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 milder climates and may not be as effective during Williston's cold winters.
  • Packaged heating and air: Packaged HVAC systems work best in smaller houses. They consist of a single combined air conditioner and heating unit, commonly located in an attic or basement. This unit is typically small, energy-efficient, and straightforward to maintain.

The cost of HVAC maintenance also varies depending on the kind of work being done. HVAC systems are complicated and can require different kinds of maintenance. The cost of some common repairs is as follows:

HVAC Unit TypeCost
Split$1,981-$5,049
Hybrid Split$4,014-$7,394
Heat Pump$3,108-$31,667
Packaged Heating and Air$260-$433

Ways to Save Money on HVAC Costs

HVAC system repairs and replacements are important, but can be pricey. Luckily, homeowners can take steps 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 consistently checking your thermostat and energy bills, allows you to 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 decreases the amount of work your HVAC system is required to do.
  • Change filters regularly. Replacing or cleaning your air filters every 30–90 days helps air flow efficiently through your system. Also try to keep debris away from the outside areas of your HVAC system as much as possible.
  • Keep your system clean. Regularly cleaning indoor evaporator coil, grills, condenser fan blades, and ductwork helps keep your HVAC system running efficiently and reduces the risk of mold. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.
ServiceCost
Filter Replacement$65-$173
Condensor Cleaning$1,300-$3,901
Thermostat Repair$87-$217
Ductwork Cleaning$416-$1,040

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 fix your system, providing you with effective heating and cooling in 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, timeframes, and warranties. Avoid providers that pressure you or demand upfront payment.

Check Credentials

When selecting an HVAC provider, choose one with technicians that have the proper 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." An individual 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.

Vermont doesn't have state-level licensing requirements for HVAC contractors, but a contractor will need to be certified by the Division of Fire Safety in order to install or service natural gas, propane or oil-burning units. Individuals must also be certified to work on electrical refrigeration and air conditioning units.

It's a good idea to look into whether your city or municipal government has any additional requirements. You should also read reviews and complaints on sites like Yelp, the Better Business Bureau (BBB), and Google Reviews. Pick a company with positive reviews and testimonials about good customer experiences.

Understand Work Details

Always make sure you know the details of a planned project. For HVAC repairs, your provider should detail which parts require replacement and why. Confirm that your technician will clean and test your system after repairs are finished to ensure that it’s working properly. When replacing your HVAC, ask the contractor to describe the new model, estimated installation time, energy efficiency, brand, 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 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 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 quote before HVAC work begins. A comprehensive quote includes both materials and labor costs. Make sure you understand and agree to all terms before signing the contract.

Frequently Asked Questions About HVAC in Williston, VT

Normally, your HVAC system should be 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 start to notice any issues, such as unusual smells, strange noises, or leaks. If your home has ductwork, it should be serviced every few years.

The best times of the year to have an HVAC inspection are during the spring and fall. Technicians are often 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 gets the most use.

You can save energy during the winter by reducing how much power your HVAC system uses to heat your home. Keep your thermostat as low as is comfortable and don't make drastic temperature changes — increase or decrease it a few degrees at a time. If possible, try switching to a smart thermostat.

It takes roughly one to three days to have your HVAC system installed or replaced. If you only need an air conditioning unit or a furnace, this can 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 uncovers.

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

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

Your HVAC company may provide financing options through a third-party lender, or you might choose to obtain a loan on your own. It's a good idea 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 a number of ways you can make your HVAC system more energy-efficient:

  • Make sure your air ducts remain clean, and clean or change your air filters on a regular basis.
  • Schedule regular inspections to take care of issues 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 the temperature indoors as close to the outside temperature as is comfortable.
  • When it comes time to replace any part of your HVAC system, explore Energy Star-certified or similar environmentally friendly options.
