Signs You May Need HVAC Repair or Replacement

If your HVAC system is faulty or getting near the end of its lifespan, it likely needs repairs or replacement from an HVAC company. Watch for these indicators your system needs service:

  • Corrosion, cracking, or rust
  • Temperature control issues or thermostat malfunctions
  • Higher than normal energy bills
  • Frequent breakdowns and need for repairs
  • Odd noises when turning on
  • Refrigerant leaks
  • Uneven heating/cooling or poor air circulation
  • An HVAC system that's over 15 years old

If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can pinpoint problems and recommend whether repair or full HVAC replacement is required.

Cost of HVAC Installation and Maintenance in Antioch

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

  • Split or mini-split: If your home lacks the ductwork for central air or heating, you probably have a split or mini-split system instead. Split HVAC systems have interior units in each room to regulate temperature. These connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system performs similarly to a standard split system, but is able to utilize either gas or electricity as energy sources.
  • Heat pump: Heat pumps exchange hot and cold air between your home and the outdoors. They don't generate their own heating and cooling, so they work more effectively in more moderate climates and may not be as effective during Antioch's hot summers.
  • Packaged heating and air: Packaged HVAC systems are more popular in smaller houses. These systems consist of a single combined heating and cooling unit, normally located in a basement or attic. This unit tends to be compact, efficient, and easy to maintain.

The cost of HVAC maintenance also varies depending on what kind of work being done. HVAC systems are complex and may require different kinds of maintenance. The prices of some common jobs are 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

Taking care of necessary HVAC repairs and replacements when needed is crucial, but can be costly. Thankfully, there are steps you can take to slow the wear and tear on your system.

  • Change the position of your blinds seasonally. Leaving your blinds open during the winter allows passive solar heating to warm your home. Closing the blinds in warmer seasons helps prevent the heat from getting inside. Doing both helps decrease the demand on your HVAC system.
  • Keep your system clean. Regularly cleaning condenser fan blades, grills, ductwork, and indoor evaporator coil helps your HVAC system run efficiently and lowers the risk of mold. The National Air Duct Cleaners Association advises cleaning your HVAC system when it starts to look dirty.
  • Monitor for potential problems. Monitoring your system for problems — for example, by checking your thermostat and energy bills routinely — helps you get ahead of problems before they get too expensive.
  • Change filters regularly. Changing your air filters or washing them every 30–90 days allows smooth air circulation through your HVAC system. Also try to keep debris from accumulating on the external 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 the indicators of a good HVAC company is important. Working with a contractor that's properly licensed and highly experienced will give you confidence that they can keep your system running efficiently, providing you with effective heating and cooling in your home.

Compare Multiple Bids

Get quotes from at least three HVAC contractors. Describe your issues and ask if specialists can inspect your system in person. Review each company's diagnoses, recommended solutions, estimated cost, warranties, and timelines. Avoid companies that pressure you or demand payment before work.

Check Credentials

When picking an HVAC provider, choose one with technicians that have the appropriate training, licenses, and experience. In all states, HVAC contractors 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 on a state-by-state basis.

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 read reviews and complaints on sites like the Better Business Bureau (BBB), Google Reviews, and Yelp. Pick a company with glowing reviews and testimonials about good customer experiences.

Understand Work Details

It’s important to know what the work process will look like. For HVAC repairs, the company should explain the exact parts that need replacement and why. Confirm that your technician will clean and test the full system afterward to ensure proper functioning. When replacing your HVAC, ask the contractor to provide details on the new estimated installation time, features, model, brand, and energy efficiency. Before signing a contract, make sure you understand the process your provider will use to select the correctly sized system for your home and what the cost will be.

Compare Warranties

Trustworthy HVAC companies stand behind their services with warranties. Compare warranties from different companies, bearing in mind that broader coverage is better. Look for the provider that offers the most coverage for a fair price.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Antioch, CA

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

Normally, 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 try to avoid making drastic changes in temperature all at once. Keep your roof well-maintained and seal any leaks around your windows and doors to avoid letting cool air escape. Similarly, make sure your attic is well ventilated to avoid trapping excess heat in your home.

Generally, HVAC installation or replacement takes between one and three days for the entire system. Installing or replacing a furnace or air conditioning unit takes anywhere from about half a day up to two days. The exact amount of time will be based on factors like the size of your house, how easily accessible different parts of the system are, and whether your technician runs into any problems.

For a 2,000-square-foot home, look for a furnace that's between 50,000 and 80,000 BTUs (British thermal units). In Antioch, you may be able to make do with a furnace on the lower end of this range.

For a 2,000-square-foot home, you'll also want to look for an air conditioning unit with around 2.5 to 5 tons of capacity. In Antioch, you'll likely want a unit on the higher end of this range. Generally, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.

Normally, HVAC financing is provided by a third-party lender. If your HVAC company doesn't offer financing, you may consider taking out your own loan. Be sure to speak with your HVAC company and a financial advisor to learn what options are available to you and appropriate for your situation.

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.
  • Have regular inspections to take care of problems as they arise.
  • Keep your attic well-ventilated and make sure all doors and windows are well-sealed.
  • Install a smart thermostat. If you aren't able to purchase 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.
