Signs You May Need HVAC Repair or Replacement

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

  • Thermostat malfunctions or temperature control issues
  • Odd noises when the system turns on
  • Frequent breakdowns and need for repairs
  • Unusually high energy bills
  • Refrigerant leaks
  • Poor air circulation or uneven heating/cooling
  • Cracking, rust, or corrosion
  • 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 determine whether repair or full HVAC replacement is the best course of action.

Cost of HVAC Installation and Maintenance in San Carlos

The price of HVAC installation or maintenance changes depending on the type of unit you have. Common types of HVAC units include the following:

  • Split or mini-split: If your home doesn't have the right ductwork for central heating or air, you probably have a split HVAC system. Split or mini-split systems consist of indoor units that regulate the temperature in individual rooms, and that are all connected 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 being able to utilize either electricity or gas for power.
  • Heat pump: Heat pumps work by moving warm and cool air between your home and the outdoors. These systems don't generate heat or air conditioning themselves, and are better for more moderate climates.
  • Packaged heating and air: Packaged HVAC systems work well in smaller houses. They consist of a single combined air conditioner and heating unit, typically located in a basement or attic. This unit is typically space-saving, energy-efficient, and easy to maintain.

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

HVAC Unit Type Cost
Split $2,119-$5,402
Hybrid Split $4,294-$7,911
Heat Pump $3,325-$33,879
Packaged Heating and Air $278-$464

Ways to Save Money on HVAC Costs

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

  • Keep your system clean. Regularly cleaning ductwork, condenser fan blades, indoor evaporator coil, and grills helps keep your HVAC system running efficiently and reduces the risk of mold. The National Air Duct Cleaners Association advises cleaning your heating and cooling system when it starts to look dirty.
  • 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 frequency with which you need to run your HVAC.
  • Monitor for potential problems. Monitoring the efficiency of your HVAC system — for instance by checking your thermostat settings and energy bills — helps you find and solve issues before they get out of hand.
  • Change filters regularly. Changing or cleaning your air filters every 30–90 days helps air flow smoothly through your HVAC system. We also recommend regularly clearing dirt and debris away from the external parts of your system.

Service Cost
Filter Replacement $70-$185
Condensor Cleaning $1,391-$4,173
Thermostat Repair $93-$232
Ductwork Cleaning $445-$1,113

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is crucial for a successful project. Look for an experienced, licensed contractor that can offer you peace of mind and ensure 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 contractors' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid companies that pressure you or demand upfront payment.

Check Credentials

It's important to choose an HVAC company that employs technicians with the proper qualifications and expertise. HVAC contractors in all states have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, a contractor must pass an exam (the type of 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 on a state-by-state basis.

HVAC contractors in California must be licensed by the Department of Consumer Affairs Contractors State License Board (CSLB). HVAC contractors are considered specialty contractors by the CSLB. 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 reviews and complaints on sites like the Better Business Bureau (BBB), Google Reviews, and Yelp. Choose a company with glowing reviews and reports of great customer experiences.

Understand Work Details

Always make sure you understand what a company’s process looks like. When HVAC repairs are needed, ask your provider to specify which parts need replacement and why. Confirm that your technician will clean and test your system afterward to guarantee proper operation. When replacing your HVAC, ask the provider to explain the new model, features, estimated installation time, energy efficiency, and brand. Before work starts, be 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

Trustworthy HVAC companies back their services with warranties. Compare warranties from different companies, keeping in mind that more comprehensive coverage is better. Look for the company that offers the most coverage for a reasonable price.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in San Carlos, CA

You should have your HVAC system inspected approximately twice yearly. After completing their inspection, your technician will inform you if any services are required. You should also schedule an inspection 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.

Generally, it's a good idea to have your HVAC system inspected 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 probably sees the most use.

You can save energy throughout the year by making it easier for your HVAC system to maintain your home's temperature. During all seasons, keep your thermostat as close to the outside temperature as you can, and try to adjust it only a few degrees at a time. You might also consider a smart thermostat.

It takes roughly one to three days to have an HVAC system installed or replaced. If you need just a furnace or a single air conditioning unit, this can take anywhere from a few hours up to two days. This timeline will be determined by the size of your home, the accessibility of your system, and any issues your technician uncovers.

For a 2,000-square-foot home, you'll want a furnace that's between 50,000 and 80,000 BTUs (British thermal units). In San Carlos, 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 an air conditioning unit with between 2.5 and 5 tons of capacity. Usually, 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 provide financing options through a third-party lender, or you may choose to obtain your own loan. It's smart to discuss payment options with a financial advisor and your HVAC company to make sure that you find the best option for you.

There are several ways you can make your HVAC system more energy-efficient:

  • Keep your air ducts clean and change or clean your air filters on a regular basis.
  • Have regular inspections to take care of issues 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 aren't able to purchase one, try keeping your inside temperature as close to the outside temperature as is comfortable.
  • When you need to replace part of your system, see if there are Energy Star-certified or similar environmentally friendly options.
