Signs You May Need HVAC Repair or Replacement

If your home's HVAC system isn't working correctly or nearing the end of its lifespan, you may need to hire an HVAC contractor for repairs or replacement. Watch for these common indicators that your system needs expert attention:

  • Refrigerant leaks
  • Temperature control issues or thermostat malfunctions
  • Frequent breakdowns and need for repairs
  • Unusually high energy bills
  • Corrosion, rust, or cracking
  • Uneven heating/cooling or poor air circulation
  • Odd noises when turning on
  • 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 decide whether fixing or replacing your HVAC unit is the correct solution.

Cost of HVAC Installation and Maintenance in Issaquah

The price of HVAC installation or maintenance varies depending on the type of unit you have. Common varieties of HVAC units include the following:

  • Split or mini-split: If your home's ductwork can't accommodate a central HVAC system, you probably have a split or mini-split system. Split systems have indoor units in each room to control temperature. These indoor units all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions very similarly to a standard split system. It has the benefit of having the capability to use either electricity or gas for power.
  • Heat pump: Heat pumps move warm and cool air between your home and outside. They don't make their own heating and cooling, so they work best in more moderate climates.
  • Packaged heating and air: Packaged HVAC systems are a smart choice for smaller houses. These systems have a single combined AC and heating, normally located in a basement or attic. They're space-saving, cost-effective, and easy to maintain.

HVAC maintenance prices vary based on the specific services required. HVAC systems can be complex and potentially require a number of services. Costs for typical jobs are as follows:

HVAC Unit TypeCost
Split$2,063-$5,259
Hybrid Split$4,180-$7,701
Heat Pump$3,236-$32,978
Packaged Heating and Air$271-$451

Ways to Save Money on HVAC Costs

HVAC system repairs and replacements are important, but can be expensive. Fortunately, homeowners can take steps to reduce wear and tear on their HVAC and lower future maintenance needs.

  • Change filters regularly. Air flows most effectively through your HVAC system when you replace or clean the filters every 1–3 months. Also avoid letting debris pile up on the external sections of your HVAC.
  • Change the position of your blinds seasonally. During winter, leaving your blinds open allows your home to benefit from passive solar heating. In the summer, keeping your blinds shut helps to block out heat. Doing both decreases the amount of work your HVAC system must perform.
  • Monitor for potential problems. Keep an eye on your system for issues, for example by consistently checking your thermostat and energy bills. This enables you to address issues before they get out of hand.
  • Keep your system clean. Keeping your ductwork, indoor evaporator coil, grills, and condenser fan blades clean helps your HVAC system function properly and lowers the risk of mold. The National Air Duct Cleaners Association recommends cleaning your home's HVAC when you notice it starting to get dirty.
ServiceCost
Filter Replacement$68-$181
Condensor Cleaning$1,354-$4,062
Thermostat Repair$90-$226
Ductwork Cleaning$433-$1,083

How To Choose a Local HVAC Company

Knowing the indicators of a reliable HVAC company is key for a smooth installation or repair. Picking an established business with certified technicians gives you assurance your HVAC system will deliver consistent heating and cooling year-round.

Compare Multiple Bids

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

Check Credentials

Look for an HVAC company that employs skilled technicians who have the necessary training and licenses. In all states, HVAC contractors must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for all technicians who "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 the type of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled by the state.

In the state of Washington, HVAC contractors are required to be licensed as specialty contractors. Individuals must have a speciality HVAC license and may also require electrical or plumbing licensure depending on the type of job. Licensing is handled by the State Department of Labor and Industries, which mandates that contractors must be both bonded and insured. Reviewing feedback on Google Reviews, Yelp, the Better Business Bureau (BBB), and similar sites can assist your decision. Choose a provider with great reviews and reports of positive experiences from customers.

Understand Work Details

Make sure you know the details of any project before it begins. If HVAC repairs are required, have your provider list which parts require replacement and why. Confirm that your technician will clean and test the entire system after the repair to verify that everything works. When replacing your HVAC, request that the company explain the new estimated installation time, model, features, brand, and energy efficiency. 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

Trustworthy HVAC companies back their work with warranties. Look at warranties from different companies, keeping in mind that more comprehensive coverage is better. Look for the provider that offers the most coverage for a reasonable price.

Get Quote in Writing

Always get HVAC bids in writing before work begins. A comprehensive quote covers costs for both materials and labor. Make sure that you understand all terms before signing the contract.

Frequently Asked Questions About HVAC in Issaquah, WA

Generally, your HVAC system should be inspected twice a year. After that inspection, your HVAC technician will tell you what services are needed. You should also have an inspection if you notice any new 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 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, 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 is comfortable and avoid making drastic temperature changes — only increase or decrease it a few degrees at a time. If possible, try switching to a smart thermostat.

Generally, whole-system HVAC installation or replacement takes one to three days. Installing or replacing a furnace or air conditioning unit can take as little as half a day or as much as two days. The exact amount of time will depend on factors like the size of your house, how easily accessible different areas are, and whether your technician discovers any problems.

For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. In Issaquah, you can probably make do with a unit that's on the lower end of this range. If your home is larger than 1,000 square feet, central air is likely to 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).

Your HVAC company might offer financing options via a third-party lender, or you may be able to obtain a loan on your own. It's a good idea to discuss payment options with your HVAC company and a financial advisor 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:

  • Keep ductwork clean, and change or clean your air filters on a regular basis.
  • 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 keeping your inside temperature as close to the outside temperature as is comfortable.
  • When you need to replace part of your HVAC system, explore Energy Star-certified or other environmentally friendly options.
