Signs You May Need HVAC Repair or Replacement

A malfunctioning or aging HVAC system probably needs professional attention from a technician who can make repairs or install a new unit. Watch out for these common signs that your HVAC needs service:

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

Book an inspection if you notice any of these problems. A local technician can inspect your system, identify problems, and figure out whether you need repairs or a new HVAC unit.

Cost of HVAC Installation and Maintenance in Fremont

What you pay for HVAC installation or maintenance varies based on your system style. Common HVAC unit styles 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 regulate temperature. These indoor units connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system works almost the same as a standard split system. It has the benefit of having the capability to use either electricity or gas for power.
  • Heat pump: Heat pumps transfer hot and cool air between your home and outside. They don't produce their own heat or AC, so they function best in moderate climates and may not be as effective during Fremont's hot summers.
  • Packaged heating and air: Packaged HVAC systems are often a good option for smaller houses. Packaged systems consist of a single combined heating and cooling unit that's typically located in a basement or attic. This unit tends to be efficient, compact, and easy to maintain.

HVAC maintenance costs differ based on the specific services required. HVAC systems can be complex and potentially require several different services. Costs for typical jobs are as follows:

HVAC Unit TypeCost
Split$2,094-$5,338
Hybrid Split$4,243-$7,817
Heat Pump$3,285-$33,475
Packaged Heating and Air$275-$458

Ways to Save Money on HVAC Costs

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

  • 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.
  • Keep your system clean. Keeping your grills, indoor evaporator coil, ductwork, and condenser fan blades clean helps your system function optimally and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.
  • Change filters regularly. Changing your air filters or washing them every 1–3 months allows effective air circulation through your system. You should also try to keep debris from accumulating on the outdoor sections of your HVAC.
  • Monitor for potential problems. Monitoring 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 out of hand.
ServiceCost
Filter Replacement$69-$183
Condensor Cleaning$1,375-$4,124
Thermostat Repair$92-$229
Ductwork Cleaning$440-$1,100

How To Choose a Local HVAC Company

It's important to know what makes a good HVAC company. 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 air conditioning and heating in your home.

Compare Multiple Bids

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

Check Credentials

When selecting an HVAC provider, choose one with technicians that have the appropriate training, licenses, and experience. HVAC contractors in all states must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for any individual who helps "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 what kind of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled at the state level.

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 are required to have four years of experience and to be bonded, and contractors with employees must also meet insurance requirements. You should also look at a company's reviews and complaints on sites such as the Better Business Bureau (BBB), Yelp, and Google Reviews. Pick a company with positive feedback and good customer testimonials.

Understand Work Details

It’s important to understand what the work process is going to look like. For HVAC repairs, the company should detail the specific 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 system, request that the installation company describe the new energy efficiency, model, brand, estimated installation time, and features. Before signing a contract, ask about the process your provider will use to properly size the new system for your home and how much it will cost.

Compare Warranties

Good HVAC companies offer warranties on repairs and installations. The more complete the coverage, the better. Compare warranty details between providers and pick the one that offers 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 review all terms before signing a contract.

Frequently Asked Questions About HVAC in Fremont, CA

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

The best times of the year to have an HVAC inspection are the spring and fall. Technicians are generally less busy during these times, so it will be 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 summer by making it easier for your HVAC system to keep your home cool. Keep your thermostat temperature 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 doors and windows 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 one to three days for the entire system. Installing or replacing an air conditioning unit or a furnace may take anywhere from a few hours up to two days. The exact amount of time will vary depending on things like how large your home is, how easily accessible different sections are, and whether your technician discovers any problems.

For a 2,000-square-foot home, you should look for a furnace that's between 50,000 and 80,000 BTUs (British thermal units). In Fremont, 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 between 2.5 and 5 tons of capacity. In Fremont, you'll likely look for a unit on the higher end of this range. Generally, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.

Your HVAC company may have financing options through a third-party lender, or you may choose to obtain your own loan. 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.
