Maximum Comfort Heat and Air ConditioningAC Repair

AC Service in El Cajon, CA

As a full-service AC company, we understand that every air conditioner is different. Yes, they all have similar functions and components, but their installation and issues are always custom to each home. As such, we use a battle-tested method to diagnose air conditioner problems.

When we show up for an air conditioning service in El Cajon, CA, we check the following things:

  • Air filters
  • Thermostat
  • Condenser and evaporator coils
  • Drain lines and pipes
  • Condensation pumps
  • Blowers and condenser fans
  • All electrical components and controls
  • Ductwork and registers

If there’s a problem with your AC, we will find it when we check each of these systems. However, there are some things you can do to help us do our job. Below are some easy troubleshooting steps you can take when your AC malfunctions.

Check the Thermostat

First off, make sure that your thermostat screen is operational. When the screen is dark, the batteries are dead, you have tripped breakers, or your thermostat is malfunctioning. Check the circuit breakers, and see if that helps.

If that doesn’t work, see if your thermostat has batteries and change them. If that doesn't work, your thermostat likely needs a replacement.

Check the Outdoor Unit

The best way to help your outdoor unit is by maintaining it regularly throughout the year. Keep it free of debris, and cut back any tree limbs, vines, or plants that would reduce airflow to the unit. Additionally, wash the coils from time to time using a low-pressure hose and a vacuum with a brush attachment.

There are also fin combs available through hardware stores that will help you straighten the fins on your unit if they ever bend. Bent fins lead to airflow problems in the long run, so combing the bends out will lengthen your AC unit's lifespan considerably.

Change Air Filters

Changing your air filter is the easiest thing you can do as a homeowner, but it is often the most neglected form of maintenance. Air filters keep dust, animal hair, and debris from entering the duct that pulls air into the system. If you don't change your AC unit's filter regularly, it will limit the ability of your AC unit to draw in air.

Additionally, make sure you use medium-strength filters to catch debris. Light-duty filters don't capture enough debris, while too many allergen trapping and heavy-duty filters restrict airflow. Filters with a good balance of filtration and airflow are best for your AC unit.

Common AC Problems in El Cajon, CA

When you have over ten years of experience, it’s easy to narrow down problems with an AC unit just by hearing what it’s doing. When you call us to schedule your air conditioning repair in El Cajon, CA, we will ask a couple quesitons to better understand your system. We’ll come more prepared and better equipped to deal with the problem with detailed foreknowledge.

That said, there are still some prevalent problems with AC units that we see daily. Here are just a few of the most common ones.

The AC Unit Doesn’t Turn On

When your AC unit doesn't turn on, it's usually because of electrical problems. For example, there could be a blown fuse, corroded wire, or tripped breaker somewhere. It may even be a faulty thermostat or temperature sensor.

There are also less common reasons for an AC not turning on, such as a failed capacitor or a damaged motor. If you have a damaged capacitor, let us change it because changing electrical components can be dangerous. If you have a damaged motor, it's time to decide between repair or replacement.

Ac Constantly Running | AC Won't Turn Off

A constantly-running AC unit will cause significant damage if you don't address it early enough. If it cannot reach a cool temperature, there is either poor airflow, a ductwork leak, bad thermostat, or low refrigerant. Thankfully, these are all relatively easy fixes if you catch them early.

If your AC runs well, but the air isn't cool enough, there is likely loose ductwork somewhere. When we fix this, we'll search under the house or in the attic—depending on the location of the ductwork—and reattach any loose sections we find.

If the air is hot, then there is a problem with the outdoor unit. It may be a bad compressor, low refrigerant which requires simple repairs. It may also mean that your AC is too small for your house and can no longer operate correctly.

The AC Unit Cools Rooms Unevenly

Uneven cooling is usually an airflow problem. There are likely some loose ducts that need reattaching or ducts with holes or tears from rodents in the crawlspaces. Another possibility is a blocked vent.

Blocked vents are easy to fix because there is most likely some furniture somewhere preventing the cool air from flowing into the house. It may also mean that there are blocked or damaged registers. Check under and behind the furniture throughout your home for vents you may have accidentally covered.

There Is a Clogged Drain Pan

Your AC unit removes moisture from your home while it cools. All that moisture collects in the drain pan that sits under the evaporator coils, then drains outside through the drain line. In places with high humidity, these lines clog often.

AC Freezing Up

If your air conditioner keeps freezing up, it’s often a sign of restricted airflow, dirty filters, or low refrigerant levels. A frozen AC can quickly turn into bigger repair issues if left unchecked. Learn more about the common reasons your AC freezes up and how to fix the problem before it damages your system.

Generally, you should change out your air filters once every three months. If you buy certain filters, they may require that you change them more often. In addition, if you have pets, children, or have lots of dirt in or around your home, you should change them more often to protect your home’s indoor air quality.

You should service your air conditioner at least twice a year. Fall and spring servicing will help keep your AC unit clean and prolong its lifespan while reducing the risk of unexpected breakdowns. Keeping the unit clean will also help us find any problems before the extreme temperatures of summer and winter.

The best way to lower your bill is to set the temperature in your home higher in the summer and lower in the winter. Keeping the temperature moderate will prevent your AC from struggling to cool your home, saving you money on your monthly power bill.

While we offer air conditioning repair in El Cajon, CA, and the Greater San Diego area, we also specialize in installing new systems. We can help you decide what system is best for your home and budget.

A heat pump removes heat from inside the home and transfers it outside. Heat pumps are more efficient than central air systems, especially in more moderate climates like California’s. However, while a central AC unit is less efficient, it is more effective in larger homes and more extreme environments.

Our technicians can help you determine which heating and cooling system is best for your home by performing a comprehensive inspection and discussing your indoor air control needs with you. Once we know what system works best for your house and budget, we can help you narrow down your options and find the perfect unit.

Several things make your AC unit use more electricity and increase your monthly power bill. One straightforward explanation is that this month is hotter than usual, making your AC work harder.

Several different components work together in your air conditioner to cool your home. If any of these components malfunction, your AC must work harder to cool your home, raising your power bill. When we look at your AC, we will find which part is wearing out and replace it as quickly as possible.

There are multiple reasons why your air conditioner is using more energy than normal:

  • It’s too small for your house
  • It’s old
  • It has one or more malfunctioning components

Our technicians can inspect your unit, locate the cause of the problem, and restore your unit’s energy efficiency.

An air conditioner leaking water outside your home is normal, as the AC removes humidity and condensation from your home. An Air conditioner leaking water inside your home is not normal and should be addressed immediately. A clogged drain line, frozen condenser coils, low refrigerant, or a damaged drain pan are all common causes for an AC leaking water in your home. Our licensed technicians provide fast AC repair in El Cajon to fix leaks and prevent further damage to your system and home.

You should consider replacing your AC unit if it is between ten and 15 years old. Older systems are significantly less efficient, leading to higher repair costs and energy bills. Replacing an old or constantly malfunctioning unit can save you money in the long run while keeping your home more comfortable.

Our technicians will only suggest that you replace your AC unit if we deem it the most cost-efficient or safe solution. After a thorough inspection of your system, we’ll help you compare repair costs to new system installation expenses and help you determine the best course of action.
