Signs You May Need HVAC Repair or Replacement

If your home's HVAC system isn't working correctly or suffering from a lot of wear and tear, you may need to hire an HVAC contractor for repairs or replacement. Watch for these common indicators that your system requires professional attention:

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

Schedule an inspection if you notice any of these issues. A local technician can assess your system, detect problems, and decide whether you need repairs or a new HVAC unit.

Cost of HVAC Installation and Maintenance in Monrovia

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

  • Split or mini-split: If your home's ductwork can't accommodate a central HVAC system, you likely have a split or mini-split system. Split systems have interior units in each room to control temperature. These indoor units all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system operates similar to a normal split system, but has the advantage of being able to utilize energy from either electric or gas sources.
  • Heat pump: Heat pumps exchange hot and cool air between your home and outside. They don't make their own heat or AC, so they work best in temperate climates and may not be as effective during Monrovia's hot summers.
  • Packaged heating and air: Packaged HVAC systems are a good choice for smaller houses. These systems have a single heating and cooling unit, typically located in a basement or attic. They're small, energy-efficient, and easy to maintain.

HVAC expenses 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$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 repair or replace your HVAC system when it's broken, but it can also be expensive. Fortunately, there are steps you can take to reduce wear and tear on your HVAC.

  • Change filters regularly. Air flows most effectively through your HVAC system when you change out or clean the filters every 1–3 months. Also try not to let debris pile up on the external sections of your HVAC.
  • Monitor for potential problems. Monitoring your system for issues — for example, by checking your thermostat and energy bills routinely — helps you catch issues before they get too expensive.
  • Keep your system clean. Cleaning your ductwork, indoor evaporator coil, grills, and condenser fan blades regularly helps your HVAC system work efficiently 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 the position of your blinds seasonally. Opening your blinds in winter allows passive solar heat into your house. Closing your blinds in summer blocks some heat from getting indoors. Both of these measures help lower the work required from your home’s HVAC system.
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 to look for in an HVAC company is crucial for a successful project. Partnering with an experienced, licensed contractor can offer you peace of mind and ensure your system provides reliable heating and air conditioning for your home.

Compare Multiple Bids

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

Check Credentials

When selecting an HVAC company, choose one with technicians that have the appropriate training, licenses, and experience. HVAC contractors in all states need to 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." 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 on a state-by-state basis.

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. Always check a provider's reviews and complaints with organizations such as Google Reviews, Yelp, and the Better Business Bureau (BBB). You'll want to select a company with glowing reviews and stories of positive service experiences.

Understand Work Details

It’s important to know what the work process is going to 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 your system afterward to guarantee everything is working correctly. When replacing your HVAC, request that the company explain the new model, features, energy efficiency, estimated installation time, and brand. Before signing paperwork, be sure you understand how your provider will determine the right system size for your home and what the price will be.

Compare Warranties

Reputable HVAC companies stand behind their services with warranties. Compare warranties from different companies, remembering that more comprehensive coverage is better. Look for the provider that offers the most coverage for a fair price.

Get Quote in Writing

Always get estimates for HVAC service in writing before work begins. A detailed quote should cover both labor and materials. Make sure you agree to all terms before signing a contract.

Frequently Asked Questions About HVAC in Monrovia, CA

Typically, you should have your HVAC system inspected twice a year. After that inspection, your HVAC technician will tell you what, if any, services are needed. You should also have your system inspected and serviced if you notice any new issues, like leaks, unusual smells, or strange noises. If your home has ductwork, 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 often 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, the times of the year when it gets 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 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 between one and three days for the entire system. Installing or replacing a furnace or air conditioning unit can take as little as half a day or as much as two days. The exact amount of time will depend on factors like the size of your home, how easily accessible different sections are, and whether your technician runs into any problems.

For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. In Monrovia, you'll probably want to choose a unit that's on the higher end of this range. If your home is larger than 1,000 square feet, central air will be more effective for cooling than window units.

For a 2,000-square-foot home, you should also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units). In Monrovia, you might be able to make do with a lower-capacity furnace.

Normally, HVAC financing is through a third-party lender. If your HVAC company doesn't have financing options, you may consider taking out your own loan. Be sure to talk to your HVAC company and a financial advisor to determine what options are available to you and appropriate for your situation.

There are a number of ways you can make your HVAC system more energy-efficient:

  • Keep ductwork clean, and clean or change your air filters on a regular basis.
  • Have regular inspections to take care of issues as they come up.
  • 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 to keep 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 other environmentally friendly options.
