Signs You May Need HVAC Repair or Replacement

An HVAC system that's not working properly or past its lifespan likely needs professional attention for maintenance or replacement. Watch for these indicators that your system needs service:

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

If you notice any of the above, have a local HVAC technician inspect your system. They can identify problems and let you know whether repair or full HVAC replacement is the better solution.

Cost of HVAC Installation and Maintenance in Cupertino

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 doesn’t have the ductwork for central air or heating, you likely have a split or mini-split system instead. Split HVAC systems have internal units in each room to regulate temperature. These connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system operates similar to a normal split system, but has the benefit of being able to utilize energy from either gas or electric sources.
  • Heat pump: Heat pumps move hot and cold air between your home and the outdoors. They don't create their own heating and cooling, so they work more effectively in more temperate climates and may not be as effective during Cupertino's hot summers.
  • Packaged heating and air: Packaged HVAC systems are a good choice for smaller houses. These systems have a single combined AC and heating, normally located in an attic or basement. They're small, cost-effective, and easy to maintain.

The amount you spend on HVAC maintenance also depends on what kind of work you're having done. HVAC systems are complex and might require different kinds of maintenance. The prices of some common jobs are as follows:

HVAC Unit Type Cost
Split $2,049-$5,224
Hybrid Split $4,152-$7,650
Heat Pump $3,215-$32,762
Packaged Heating and Air $269-$448

Ways to Save Money on HVAC Costs

It's important to take care of HVAC repairs and replacements in a timely manner, but it can also be expensive. Luckily, there are some steps you can take to slow the wear and tear on your system.

  • Monitor for potential problems. Keeping a close eye on the efficiency of your HVAC system — for instance by reviewing your thermostat settings and energy bills — helps you identify and fix problems before they get too expensive.
  • Keep your system clean. Keeping your indoor evaporator coil, condenser fan blades, ductwork, 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.
  • Change filters regularly. Switching out or cleaning your air filters every 30–90 days helps air flow efficiently through your HVAC system. We also recommend regularly clearing dirt and debris away from the external parts of your system.
  • Change the position of your blinds seasonally. Keeping your blinds open in the winter helps you take advantage of passive solar heating. Keeping them closed in the summer helps keep some of this heat out. Both of these measures help reduce the amount of work your HVAC system needs to do.

Service Cost
Filter Replacement $67-$179
Condensor Cleaning $1,345-$4,036
Thermostat Repair $90-$224
Ductwork Cleaning $430-$1,076

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is important for a successful project. Look for an experienced, licensed contractor that can give you peace of mind and make sure your system provides reliable air conditioning and heating for your home.

Compare Multiple Bids

Contact at least three HVAC companies for quotes. Explain your issues and schedule an in-person inspection if possible. Compare companies' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid providers that pressure you or demand upfront payment.

Check Credentials

Look for an HVAC company that employs skilled technicians who have the necessary training and licenses. HVAC contractors in all states need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for all contractors who "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 by the state.

HVAC contractors in California must be licensed by the Department of Consumer Affairs Contractors State License Board (CSLB). The CSLB considers HVAC contractors to be specialty contractors. All contractors must have four years of experience and be bonded. Contractors with employees must also meet insurance requirements. You should also check reviews and complaints on sites like Google Reviews, Yelp, and the Better Business Bureau (BBB). Pick a company with glowing reviews and testimonials about great customer experiences.

Understand Work Details

Always make sure you know the details of your project. When HVAC repairs are required, your provider should list which parts require replacement and why. Confirm that your technician will clean and test the system after repairs are finished to ensure that it’s working properly. When getting a replacement, ask your contractor to explain the new HVAC system features, model, estimated installation time, brand, and energy efficiency. Before work begins, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

A trustworthy HVAC company will stand behind its repair work and equipment installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully review the fine print for each contractor and choose the provider that offers the greatest protection at a reasonable price.

Get Quote in Writing

Always get quotes for HVAC service in writing before work begins. A detailed quote should cover both materials and labor. Make sure you review all terms before signing a contract.

Frequently Asked Questions About HVAC in Cupertino, CA

You should have your HVAC system inspected twice annually. At the time of the inspection, your technician will inform you what services are required. You should also schedule an inspection if you notice new issues such as unusual smells, strange noises, or leaks. If your system has ductwork, you should have it inspected every few years.

Usually, it's a good idea to schedule inspections in the spring and fall, as these times tend to be less busy. This also helps make sure your system is prepared for the summer and winter, when it typically sees the most use.

You can save energy during the summer by making it easier for your HVAC system to keep your home cool. Set your thermostat as close to the outside temperature as you can, and avoid making drastic changes in temperature all at once. Keep your roof well-maintained and seal any leaks around your doors and windows to help keep cool air in. Similarly, ensure that your attic is well ventilated to avoid trapping excess heat in your home.

It takes roughly one to three days to have your HVAC system installed or replaced. If you need just 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 runs into.

For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. In Cupertino, you'll probably want to purchase a unit on the higher end of this range. For a house over 1,000 square feet, central air will usually be more effective than window units for cooling.

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). In Cupertino, you may be able to make do with a lower-capacity furnace.

Your HVAC company may provide financing options via a third-party lender, or you may be able to obtain your own loan. It's smart 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 a number of ways you can make your HVAC system more energy-efficient:

  • Keep ductwork clean, and change or clean your air filters regularly.
  • 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 aren't able to purchase one, try to keep your inside temperature as close to the outside temperature as is comfortable.
  • When replacing part of your system, explore Energy Star-certified or similar environmentally friendly options.
