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. Keep an eye out for these common signs that your HVAC needs service:

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

If you notice any of these HVAC red flags, your system evaluated. A local company can complete an inspection, identify problems, and recommend repairing or replacing your HVAC unit.

Cost of HVAC Installation and Maintenance in Clayton

Your HVAC installation or maintenance cost changes depending on the style of unit. Common HVAC unit varieties include the following:

  • Split or mini-split: Homes without ductwork for central air often have split or mini-split HVAC systems. These systems consist of interior units in each room to control temperature, which all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions comparably to a regular split system. It provides flexibility by having the option to use either electricity or gas for energy.
  • Heat pump: Heat pumps work by circulating hot and cold air between your home and the outdoors. These systems don't generate heat or air conditioning themselves, and are more suited to more moderate climates. They may not be as effective during Clayton's hot summers.
  • Packaged heating and air: Packaged HVAC systems are a smart choice for smaller homes. They have a single cooling and heating unit, normally in a basement or attic. This unit is often small, cost-effective, and easy to maintain.

The price of HVAC maintenance also depends on the kind of work being done. HVAC systems are complex and might require different kinds of maintenance. The cost of some common repairs is as follows:

HVAC Unit TypeCost
Split$2,024-$5,159
Hybrid Split$4,100-$7,554
Heat Pump$3,175-$32,351
Packaged Heating and Air$266-$443

Ways to Save Money on HVAC Costs

Fixing your HVAC by repairing or replacing parts when needed is important, but can be expensive. Thankfully, there are actions you can take to reduce gradual wear and tear on your system.

  • 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 routinely checking your thermostat and energy bills. This allows you to address issues before they get too expensive.
  • Keep your system clean. Keeping your condenser fan blades, grills, indoor evaporator coil, and ductwork clean enables your HVAC system to function properly and lowers your risk of mold. The National Air Duct Cleaners Association suggests cleaning your home's HVAC system when you notice it starting to get dirty.
  • Change filters regularly. Air flows best through your HVAC system when you change out or clean the filters every 1–3 months. Also try not to let debris pile up on the outdoor parts of your HVAC.
ServiceCost
Filter Replacement$66-$177
Condensor Cleaning$1,328-$3,985
Thermostat Repair$89-$221
Ductwork Cleaning$425-$1,063

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is vital for a successful installation or repair. Hiring an experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning year-round.

Compare Multiple Bids

Get quotes from three or more HVAC providers. Describe your issues and ask if specialists can inspect your system in person. Review each contractor's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid providers that pressure you or demand payment before work.

Check Credentials

It's important to choose an HVAC company that employs technicians with the appropriate 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, an individual must pass an exam (the specific 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 at the state level.

In California, HVAC contractors 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 read reviews and complaints on sites like Yelp, the Better Business Bureau (BBB), and Google Reviews. Choose a company with glowing reviews and testimonials about great customer experiences.

Understand Work Details

Always make sure you know what a company’s process is like. When getting HVAC repairs, ask your provider to specify which parts need replacement and why. Confirm that your technician will clean and test the full system after finishing the work to ensure proper operation. When replacing your HVAC system, ask your contractor to provide details on the new features, energy efficiency, model, brand, and estimated installation time. Before work begins, make sure you understand how your provider will properly size the new unit for your home and what the cost will be.

Compare Warranties

Reliable HVAC companies offer warranties on repairs and installations. The more complete the coverage, the better. Review warranty details between companies and pick the one that provides the most comprehensive protection within your budget.

Get Quote in Writing

Always get quotes for HVAC service in writing before committing to a provider. An itemized quote should cover both materials and labor. Make sure you understand all terms before signing a contract.

Frequently Asked Questions About HVAC in Clayton, CA

You should have your HVAC system inspected about twice annually. After completing their inspection, your technician will inform you if any services are needed. You should also call a technician if you start noticing issues such as leaks, strange noises, or unusual smells. If your home has ductwork, you should have it inspected every few years.

Normally, it's smart to have your HVAC system inspected in the spring and fall, as technicians tend to be less busy at these times. This also helps make sure your system is prepared for the summer and winter, when it likely sees the most use.

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

For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. In Clayton, 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 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). In Clayton, you might 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 choose to obtain a loan on your own. It's smart to discuss payment options with a financial advisor and your HVAC company 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:

  • Make sure your air ducts remain clean, and clean or change your air filters regularly.
  • Have regular inspections to take care of issues 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 your inside temperature as close to the outside temperature as is comfortable.
  • When replacing part of your system, see if there are Energy Star-certified or similar environmentally friendly options.
