Signs You May Need HVAC Repair or Replacement

An HVAC system that's malfunctioning or outdated likely needs professional attention for maintenance or replacement. Watch for these signals that your system needs service:

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

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

Cost of HVAC Installation and Maintenance in Westminster

The cost of HVAC installation or maintenance changes depending on the kind of unit you have. Common kinds of HVAC units include the following:

  • Split or mini-split: Homes without ductwork for centralized climate control often have split or mini-split HVAC systems. These systems consist of interior units in each room to control temperature. These indoor units connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions in the same way as a normal split system, but has the advantage of being able to draw power from either gas or electric sources.
  • Heat pump: Heat pumps move warm and cool air between your home and the outside. These systems don't produce their own heat or AC, so they work more efficiently in more temperate climates and may not be as effective during Westminster's hot summers.
  • Packaged heating and air: Packaged HVAC systems are more popular in smaller homes. Packaged systems consist of a single combined heating and cooling unit that's normally located in an attic or basement. This unit tends to be compact, efficient, and easy to maintain.

HVAC maintenance prices vary based on the work needed. HVAC systems are complex and may need several types of maintenance. Prices for common jobs are as follows:

HVAC Unit TypeCost
Split$2,035-$5,187
Hybrid Split$4,123-$7,596
Heat Pump$3,193-$32,531
Packaged Heating and Air$267-$445

Ways to Save Money on HVAC Costs

Fixing your HVAC by repairing or replacing parts when needed is crucial, but can be costly. Thankfully, there are actions you can take to minimize wear and tear over time on your system.

  • Change the position of your blinds seasonally. Keeping your blinds closed in the summer helps block out passive solar heat. Keeping them open in the winter helps you take advantage of this same heat. Both of these measures help reduce the strain on your HVAC system.
  • Keep your system clean. Cleaning your condenser fan blades, grills, ductwork, and indoor evaporator coil regularly helps keep your HVAC system working efficiently and lowers the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it begins to look dirty.
  • 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.
  • Change filters regularly. Switching out your air filters or washing them every 30–90 days allows smooth air circulation through your HVAC system. You should also try to keep debris from accumulating on the outdoor sections of your HVAC.
ServiceCost
Filter Replacement$67-$178
Condensor Cleaning$1,336-$4,007
Thermostat Repair$89-$223
Ductwork Cleaning$427-$1,069

How To Choose a Local HVAC Company

Knowing the indicators of a reliable HVAC company is key for a smooth installation or repair. Picking an established business with certified technicians gives you assurance your HVAC system will deliver consistent heating and cooling year-round.

Compare Multiple Bids

Contact at least three HVAC companies for quotes. Describe the issues and have technicians visit to inspect your system if possible. Compare the contractors' explanations, solutions, estimated costs, timeframes, and warranties. Avoid companies that pressure you or demand payment upfront.

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, individuals must pass an exam (the type of exam depends on the kind of equipment they plan 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). The CSLB considers HVAC contractors to be specialty contractors. All contractors are required to have four years of experience and to be bonded. Contractors with employees must also meet insurance requirements. Always check a provider's reviews and complaints with organizations such as Google Reviews, Yelp, and the Better Business Bureau (BBB). You want to hire a provider with glowing reviews and stories of positive service experiences.

Understand Work Details

Always make sure you understand the details of any project. For HVAC repairs, your provider should specify which parts need replacement and why. Confirm that your technician will clean and test the full system after repairs are done to ensure that it’s working properly. When getting a replacement, ask your contractor to explain the new HVAC system brand, model, estimated installation time, features, and energy efficiency. Before work begins, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

Good HVAC companies offer warranties on repairs and equipment installations. The more complete the coverage, the better. Compare warranty details between providers and pick the one that offers the best protection for a fair price.

Get Quote in Writing

Always get quotes for HVAC service in writing before work begins. An itemized quote should cover both labor and materials. Make sure you review all terms before signing a contract.

Frequently Asked Questions About HVAC in Westminster, CA

Generally, you should have your HVAC system inspected twice a year. After an inspection, your HVAC technician will tell you what, if any, services are required. 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 of the year to have an HVAC inspection are the spring and fall. Technicians are less busy during these times, which makes it 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 avoid making drastic changes in temperature all at once. Keep your roof in good shape and seal any leaks around your windows and doors to help keep cool air in. 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 depend on things like the size of your home, how easily accessible different parts of the system 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 Westminster, 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 purchase an air conditioning unit with between 2.5 and 5 tons of capacity. In Westminster, you'll likely look for a unit on the higher end of this range. In general, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.

Your HVAC company might provide financing options via a third-party lender, or you might be able to obtain your own loan. It's a good idea 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 ductwork clean, and change or clean your air filters on a regular basis.
  • Schedule 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 don't want to or can't buy one, try keeping the temperature indoors as close to the outside temperature as is comfortable.
  • When you need to replace part of your HVAC system, explore Energy Star-certified or similar environmentally friendly options.
