Signs You May Need HVAC Repair or Replacement

An HVAC system that's broken or past its lifespan likely needs professional attention for repairs or replacement. Watch for these signs that your system needs service:

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

Schedule an inspection if you notice any of these problems. A local technician can inspect your system, identify problems, and figure out whether you need to fix or replace your HVAC.

Cost of HVAC Installation and Maintenance in Glendora

What you pay for HVAC installation or maintenance varies based on your system type. Common HVAC unit styles include the following:

  • Split or mini-split: If your home lacks the ductwork for central air or heating, you probably have a split or mini-split system instead. Split HVAC systems have indoor units in each room to manage temperature. These connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system works almost the same as a standard split system. It has the advantage of being able to utilize either gas or electricity for power.
  • Heat pump: Heat pumps work by moving warm and cool air between your home and the outdoors. These systems don't produce heat or air conditioning themselves, and are more suited to more moderate climates. They may not be as effective during Glendora's hot summers.
  • Packaged heating and air: Packaged HVAC systems are a good choice for smaller houses. These systems have a single combined AC and heating, normally located in an attic or basement. They're space-saving, energy-efficient, and easy to maintain.

The amount you spend on HVAC maintenance also varies depending on the kind of work you're having done. HVAC systems are complex and can require different kinds of maintenance. The cost of some common repairs is as follows:

HVAC Unit Type Cost
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. Luckily, there are some steps you can take to slow the wear and tear on your HVAC.

  • Keep your system clean. Cleaning your grills, indoor evaporator coil, condenser fan blades, and ductwork regularly helps keep your HVAC system working 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 filters regularly. Replacing or cleaning your air filters every 1–3 months helps air flow efficiently through your system. Also try to keep debris away from the outdoor portions of your HVAC system as much as possible.
  • 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 reduces the amount of work your HVAC system must perform.
  • Monitor for potential problems. Monitoring your system for issues — for example, by checking your thermostat and energy bills regularly — helps you get ahead of problems before they get too expensive.

Service Cost
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

Finding the right HVAC company is key 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

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

Check Credentials

Look for an HVAC company that employs skilled technicians with the necessary training and licenses. In all states, HVAC contractors 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." 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 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 are required to have four years of experience and to be bonded, and contractors with employees must also meet insurance requirements. You should also check a provider's reviews and complaints with organizations such as Google Reviews, Yelp, and the Better Business Bureau (BBB). Look for a a company with glowing reviews and stories of positive service experiences.

Understand Work Details

Make sure you know the details of your project before it begins. If HVAC repairs are required, have your provider specify which parts need replacement and why. Get confirmation that your technician will clean and test the system after the repair to verify that everything works. When replacing your HVAC system, request that the installation company describe the new energy efficiency, brand, features, estimated installation time, and model. Before work starts, ask how your provider plans to accurately size the unit for your home and how much it will cost.

Compare Warranties

A trustworthy HVAC company will back its repair services and installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully review warranty terms for each contractor and choose the company that provides the greatest protection within your budget.

Get Quote in Writing

Get a written quote before HVAC work starts. A comprehensive quote includes both labor and material costs. Make sure you understand and accept all terms before signing the contract.

Frequently Asked Questions About HVAC in Glendora, CA

Generally, your HVAC system should be inspected twice a year. After an inspection, your HVAC technician will tell you what services are needed. You should also have an inspection if you start to notice any 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 during the spring and fall. Technicians are often 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, when it typically 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 avoid making drastic changes in temperature all at once. Keep your roof well-maintained and seal any window or door leaks to help keep cool air in. Similarly, ensure that your attic is well ventilated to avoid trapping excess heat in your home.

It takes around one to three days to have an HVAC system installed or replaced. If you only need a furnace or a single air conditioning unit, this can take between half a day and two days. This timeline can be affected by the size of your home, the accessibility of your system, and any new issues your technician runs into.

For a 2,000-square-foot home, try to purchase a furnace that's between 50,000 and 80,000 BTUs (British thermal units). In Glendora, 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 around 2.5 to 5 tons of capacity. In Glendora, you'll likely want something on the higher end of this range. In general, 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 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 a number of ways you can make your HVAC system more energy-efficient:

  • Keep your air ducts clean and clean or change your air filters regularly.
  • Schedule regular inspections to take care of issues as they arise.
  • Keep your attic well-ventilated and make sure all doors and windows are well-sealed.
  • Install a smart thermostat. If you don't want to or can't buy one, try to keep your inside temperature as close to the outside temperature as you can.
  • When replacing part of your system, explore Energy Star-certified or similar environmentally friendly options.
