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An HVAC system that's malfunctioning or outdated likely needs professional attention for repairs or replacement.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

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

Schedule an inspection if you notice any of these problems. A local technician can inspect your system, detect problems, and determine whether you need repairs or a new HVAC unit.

Cost of HVAC Installation and Maintenance in Bellingham

What you pay for HVAC installation or maintenance is determined by your system style. Common HVAC unit styles include the following:

  • Split or mini-split: If your home lacks the ductwork for central heating and cooling, you probably have a split or mini-split system instead. Split HVAC systems have internal units in each room to manage temperature. These 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 advantage of being able to utilize energy from either electric or gas sources.
  • Heat pump: Heat pumps move warm and cool air between your home and the outside. These systems don't make their own heat or AC, so they work more effectively in moderate climates and may not be as effective during Bellingham's cold winters.
  • Packaged heating and air: Packaged HVAC systems are a good choice for smaller houses. They have a single heating and cooling unit, usually in an attic or basement. This unit is often small, cost-effective, and easy to maintain.

HVAC maintenance costs differ based on the specific services required. HVAC systems can be complex and potentially require several different services. Fees for typical jobs are as follows:

HVAC Unit TypeCost
Split$1,963-$5,005
Hybrid Split$3,978-$7,329
Heat Pump$3,080-$31,386
Packaged Heating and Air$258-$430

Ways to Save Money on HVAC Costs

It’s important to take care of HVAC repairs and replacements when they are required, though they can be expensive. The good news is that homeowners have methods to decrease the effect of wear and tear and reduce the frequency of breakdowns.

  • Keep your system clean. Keeping your grills, condenser fan blades, indoor evaporator coil, and ductwork 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.
  • Change filters regularly. Air flows through your HVAC system most effectively when you replace or clean the filters every 30–90 days. Also avoid letting debris pile up on the external sections of your HVAC.
  • Change the position of your blinds seasonally. Leaving your blinds open during the colder months helps warm your home with passive solar heating. Closing the blinds during the summer helps prevent the same heat from getting inside. Doing both helps reduce the demand on your HVAC system.
  • 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 out of hand.
ServiceCost
Filter Replacement$64-$172
Condensor Cleaning$1,289-$3,866
Thermostat Repair$86-$215
Ductwork Cleaning$412-$1,031

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is vital for a successful installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide reliable 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, warranties, and timeframes. Avoid providers that pressure you or demand upfront payment.

Check Credentials

It's important to choose an HVAC company that employs technicians with the proper qualifications and expertise. In all states, HVAC contractors have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, a contractor must pass an exam (the type of exam depends on what 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 by the state.

HVAC contractors are required to be licensed as specialty contractors in the state of Washington. An individual must possess a speciality HVAC license and may also require plumbing or electrical licensure depending on the type of job. Licensing is handled by the State Department of Labor and Industries, which requires contractors to be both bonded and insured. Always check a provider's reviews and complaints with organizations such as Yelp, Google Reviews, and the Better Business Bureau (BBB). You want to hire a company with glowing reviews and stories of positive service experiences.

Understand Work Details

Make sure you understand the details of your project before it begins. If HVAC repairs are required, have your provider specify which parts require replacement and why. Confirm that your technician will clean and test your system after the repair to ensure that everything works. When replacing your HVAC, request that the company explain the new estimated installation time, features, brand, energy efficiency, and model. Before signing paperwork, be sure you understand how your provider will determine the right system size for your home and what the price will be.

Compare Warranties

Reputable HVAC companies back their services with warranties. Compare warranties from different companies, keeping in mind that broader coverage is better. Look for the provider that offers the most coverage for a fair price.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Bellingham, WA

Normally, your HVAC system should be inspected twice a year. After that inspection, your technician will tell you what services are needed. You should also have an inspection if you start to notice any issues, such as leaks, unusual smells, or strange noises. 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 the spring and fall. Technicians tend to be less busy during these times, making it easier to get an appointment. This also ensures that your system is ready 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 don't make 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 roughly one to three days to have your HVAC system installed or replaced. If you only need 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 house, the accessibility of your system, and any new issues your technician uncovers.

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

For a 2,000-square-foot home, you'll also want to look for an air conditioning unit with between 2.5 and 5 tons of capacity. In Bellingham, a unit on the lower end of this range may be sufficient. Typically, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.

Usually, HVAC financing is through a third-party lender. If your HVAC company doesn't have financing options, you could consider taking out a loan on your own. Be sure to speak with a financial advisor and your HVAC company to determine what options are available to you and appropriate for your situation.

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 on a regular basis.
  • Schedule 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 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 system, explore Energy Star-certified or similar environmentally friendly options.
