Signs You May Need HVAC Repair or Replacement

If your HVAC system is broken or getting old, it likely needs repairs or replacement from an HVAC company. Watch for these indicators your system needs service:

  • Frequent breakdowns and need for repairs
  • Poor air circulation or uneven heating/cooling
  • Strange noises when turning on
  • Cracking, corrosion, or rust
  • Temperature control issues or thermostat malfunctions
  • Higher than normal energy bills
  • Refrigerant leaks
  • 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 diagnose problems and determine whether repair or full HVAC replacement is the best course of action.

Cost of HVAC Installation and Maintenance in Altadena

The cost 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 ductwork for central heating and cooling, you probably have a split or mini-split system instead. Split HVAC systems have indoor units in each room to control temperature. These connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions comparably to a regular split system. It gives flexibility by having the option to use either electricity or gas for energy.
  • Heat pump: Heat pumps exchange warm and cold air between your home and the outdoors. They don't make their own heat or AC, so they work best in temperate climates and may not be as effective during Altadena's hot summers.
  • Packaged heating and air: Packaged HVAC systems are a smart choice for smaller houses. They have a single cooling and heating unit, typically in a basement or attic. This unit is often small, energy-efficient, and easy to maintain.

HVAC costs differ based on the work needed. HVAC systems are complex and may need multiple types of maintenance. Costs for common jobs are as follows:

HVAC Unit TypeCost
Split$1,918-$4,889
Hybrid Split$3,886-$7,159
Heat Pump$3,009-$30,658
Packaged Heating and Air$252-$420

Ways to Save Money on HVAC Costs

It's important to fix or swap out your HVAC components when they become damaged, but it can also be expensive. Fortunately, there are some steps you can take to reduce wear and tear on your HVAC.

  • Keep your system clean. Regularly cleaning condenser fan blades, grills, indoor evaporator coil, and ductwork helps your HVAC system run efficiently and reduces your risk of mold. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.
  • Change the position of your blinds seasonally. During winter, leave your blinds open so your home benefits from passive solar heat. In summer, keep blinds shut to block out heat. Doing both decreases the amount of work your HVAC system must perform.
  • Change filters regularly. Air flows through your HVAC system most effectively when you replace or clean the filters every 1–3 months. Also avoid letting debris pile up on the outside areas of your HVAC.
  • Monitor for potential problems. Keeping an eye out for problems, for instance by routinely checking your thermostat and energy bills, lets you resolve them before they get too expensive.
ServiceCost
Filter Replacement$63-$168
Condensor Cleaning$1,259-$3,777
Thermostat Repair$84-$210
Ductwork Cleaning$403-$1,007

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is crucial for an easy installation or repair. Hiring an experienced, credentialed HVAC contractor gives you confidence your system can provide reliable 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. Compare each company's diagnoses, recommended solutions, estimated cost, warranties, and timeline. Avoid providers that pressure you or demand payment before work.

Check Credentials

Look for an HVAC company that employs skilled technicians who have the necessary licensure and training. HVAC contractors in all states must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for all technicians 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 the type of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled by the state.

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, and contractors with employees must also meet insurance requirements. Reviewing feedback on Google Reviews, Yelp, the Better Business Bureau (BBB), and similar sites can aid your decision as well. Choose a company with stellar reviews and stories of positive customer experiences.

Understand Work Details

Always make sure you understand what a company’s process is like. When getting HVAC repairs, ask your provider to list which parts require replacement and why. Confirm that your technician will clean and test the system afterward to ensure proper operation. For replacement, ask the contractor to explain the new HVAC system estimated installation time, brand, model, energy efficiency, and features. Before starting the project, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

Reliable HVAC companies provide warranties for their services. The broader the coverage, the better, so make sure to review warranties between providers. Choose the one that gives you the most coverage at a fair cost.

Get Quote in Writing

Always get estimates 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 Altadena, CA

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

The best times to have an HVAC inspection are during the spring and fall. Technicians tend to be less busy during these times, which makes it easier to get an appointment. This also helps get your system ready for the summer and winter, which is when it normally gets 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. 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 in good shape and seal any door or window leaks to avoid letting cool air escape. Similarly, make sure your attic is well ventilated to avoid trapping excess heat in your home.

Generally, whole-system HVAC installation or replacement takes between one and three days. 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 factors like the size of your house, how easily accessible different sections are, and whether your technician discovers any problems.

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 Altadena, you may be able to make do with a lower-capacity furnace.

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

Your HVAC company may offer financing options through a third-party lender, or you might be able to obtain a loan on your own. 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.
