Signs You May Need HVAC Repair or Replacement

If your home's HVAC system isn't working correctly or suffering from a lot of wear and tear, you might need an HVAC contractor for maintenance or replacement. Watch for these common signs that your system requires expert attention:

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

If you notice any of these HVAC issues, have a technician inspect your system. A local professional can identify problems and let you know whether whether repairing or getting a new HVAC unit is the correct solution.

Cost of HVAC Installation and Maintenance in Issaquah

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

  • Split or mini-split: Homes without ductwork for central air frequently have split or mini-split HVAC systems. These systems consist of indoor units in each room to control temperature. These indoor units connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system operates similar to a normal split system, but has the advantage of being able to utilize energy from either electric or gas sources.
  • Heat pump: Heat pumps transfer hot and cool air between your home and the outdoors. They don't produce their own heat or AC, so they perform best in temperate 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 aid 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, 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 stand behind its repair services and installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully compare warranty terms between contractors and choose the company that provides the most protection at a reasonable price.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Issaquah, WA

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

The best times to have an HVAC inspection are the spring and fall. Technicians are generally less busy during these times, which makes it easier to get an appointment. This also helps get your system ready for the summer and winter, the times of the year when it 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 — only increase or decrease it a few degrees at a time. If possible, try switching to a smart thermostat.

Generally, HVAC installation or replacement takes one to three days for the entire system. 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 vary depending on things like how large your home is, how easily accessible different parts of the system are, and whether your technician finds any problems.

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

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.
  • Have regular inspections to take care of problems 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 your inside temperature as close to the outside temperature as you can.
  • When replacing part of your HVAC system, explore Energy Star-certified or other environmentally friendly options.
