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 indicators that your HVAC needs service:

  • Thermostat malfunctions or temperature control issues
  • Frequent breakdowns and need for repairs
  • Higher than normal energy bills
  • Cracking, corrosion, or rust
  • Poor air circulation or uneven heating/cooling
  • Refrigerant leaks
  • Odd noises when the system turns on
  • 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 Monroe

The cost of HVAC installation or maintenance changes depending on the kind of unit you have. Common types of HVAC units include the following:

  • Split or mini-split: If your home doesn’t have 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 control 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 benefit of being able to utilize energy from either gas or electric sources.
  • Heat pump: Heat pumps work by transferring hot and cold air between your home and the outdoors. These systems don't generate heat or air conditioning themselves, and are better for more moderate climates.
  • Packaged heating and air: Packaged HVAC systems are a good choice for smaller homes. They have a single cooling and heating 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 needed. HVAC systems can be complicated and potentially require several different services. Price ranges for typical jobs are as follows:

HVAC Unit TypeCost
Split$1,998-$5,093
Hybrid Split$4,048-$7,458
Heat Pump$3,135-$31,940
Packaged Heating and Air$262-$437

Ways to Save Money on HVAC Costs

It's important to repair or replace your HVAC system when it's broken, but it can also be expensive. Thankfully, there are steps you can take to reduce wear and tear on your HVAC.

  • Change the position of your blinds seasonally. Leaving your blinds open during the winter helps warm your home with passive solar heating. Closing the blinds during the summer helps prevent some heat from getting inside. Doing both helps decrease the strain on your HVAC system.
  • Monitor for potential problems. Monitor your system for issues, for example by routinely checking your thermostat and energy bills. This allows you to address issues before they get too expensive.
  • Change filters regularly. Changing your air filters or washing them every 30–90 days allows efficient air circulation through your system. Also try to keep debris from accumulating on the outside components of your HVAC.
  • Keep your system clean. Keeping your ductwork, indoor evaporator coil, condenser fan blades, and grills clean helps your system function optimally and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends that you clean your HVAC system whenever it begins to look dirty.
ServiceCost
Filter Replacement$66-$175
Condensor Cleaning$1,312-$3,935
Thermostat Repair$87-$219
Ductwork Cleaning$420-$1,049

How To Choose a Local HVAC Company

Knowing the right things to look for in an 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

Get quotes from three or more HVAC contractors. Explain your issues and ask if technicians can inspect your system in person. Compare each provider's diagnoses, recommended solutions, estimated cost, warranties, and timeline. Avoid companies that pressure you or demand payment before work.

Check Credentials

Choose an HVAC company with well-trained technicians who have proper licensing and experience. HVAC contractors in all states have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, contractors 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 by the state.

In the state of Washington, HVAC contractors are required to be licensed as specialty contractors. An individual must possess a speciality HVAC license and may also require plumbing or electrical licensure depending on the job. Licensing is handled by the State Department of Labor and Industries, which mandates that contractors must be both bonded and insured. Always check a provider's reviews and complaints with organizations such as Yelp, the Better Business Bureau (BBB), and Google Reviews. Look for a a company with positive reviews and a history of good customer service.

Understand Work Details

Always make sure you understand what a company’s process is like. When getting HVAC repairs, ask your provider to specify which parts need replacement and explain why. Confirm that your technician will clean and test the full system at the end of the job to ensure proper operation. When replacing your HVAC system, request that the installation company describe the new estimated installation time, brand, model, energy efficiency, and features. Before work starts, ask about the process your provider will use to properly size the new system for your home and how much it will cost.

Compare Warranties

Reliable HVAC companies offer warranties on repairs and installations. The more complete the coverage, the better. Compare warranty details between companies and pick the one that offers the best protection for the fairest price.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Monroe, WA

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

The best times to have an HVAC inspection are during the spring and fall. Technicians are often 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, which is when it normally 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 you can and don't make drastic changes in the temperature — increase or decrease it a few degrees at a time. If you're able to, 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 an air conditioning unit or a furnace, this might take anywhere from a few hours up to two days. This timeline will be influenced by the size of your house, 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).

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 Monroe, a unit with a lower capacity may be sufficient. Generally, 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 might choose 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 find 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 change or clean your air filters on a regular basis.
  • Have regular inspections to take care of problems as they come up.
  • 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 you can.
  • When it comes time to replace any part of your HVAC system, explore Energy Star-certified or similar environmentally friendly options.
