AC Repairs

 

If your air conditioning is not working correctly, we’ll come to your home and diagnose the problem quickly. If a repair is the best option for you, we’ll make sure it is done quickly and correctly. Ac Repair Fremont locations make sure that their vehicles are well-stocked, so many repair jobs can be accomplished on the same visit as the estimate!

 

AC Installation

 

Sometimes an old air conditioning unit needs to be replaced for cost, efficiency, or other reasons. However, choosing an air conditioner is never a one-size-fits-all situation. Our AC pros come to your home to determine precisely which air conditioner will work best for you. We’ll always work with you to consider your budget, preferences, and other factors important for you and your home’s comfort.

 

AC Maintenance

 

Maintaining your air conditioner is important because it can help your unit last longer. In fact, the U.S. Department of Energy estimates homeowners could make their unit between 5 and 15 percent more efficient just through regular filter replacements! Additionally, some manufacturer and repair warranties require annual system maintenance to remain valid. We offer a range of annual maintenance plans to fit various budgets and needs. Our plans also include member perks, such as priority service and discounts on products and repairs.

Here are a few simple tips and steps that can end up saving you a lot of money when it comes to running your air conditioner.

 

Try setting your thermostat between 72°F and 78°F. Each degree setting below 78°F will increase your energy consumption by approximately 8%. As you can see, that can add up to a lot of money over a year.

 

Inspect and clean both the indoor and outdoor AC/Heating coils. The indoor coil in your air conditioner acts as a magnet for dust because it is constantly wetted during the cooling season. Dirt build-up on the indoor coil is the single most common cause of poor efficiency. The outdoor coil must also be checked periodically for dirt build-up and cleaned if necessary.

 

Check the refrigerant charge. The circulating fluid in your air conditioner is a special refrigerant gas that is put in when the system is installed. If the system is overcharged or undercharged with refrigerant, it will not work properly. You may need a service contractor to check the fluid and adjust it appropriately.

 

Use bath and kitchen fans sparsely when you are running the air conditioning system.

 

Reduce the cooling load by using cost-effective conservation measures. For example, effectively shade east and west windows. When possible, delay heat-generating activities, such as dishwashing or baking, until the evening on hot days.

 

Try to not use a dehumidifier at the same time your air conditioner is operating. The dehumidifier will increase the cooling load and force the air conditioner to work harder, which in turn increases your utility bill.

 

Over most of the cooling season, keep the house closed tight during the day. Don’t let in unwanted heat and humidity. If practical, ventilate at night either naturally or with fans.

 

Room Air Conditioning Units

 

The unit should be level when installed so that the inside drainage system and other mechanisms operate efficiently. If possible, install the unit in a shaded spot on your home’s north or east side. Direct sunshine on the unit’s outdoor heat exchanger decreases efficiency by as much as 10%. You can plant trees and shrubs to shade the air conditioner, but do not block the airflow.

 

Set the fan speed on high, except on very humid days. When humidity is high, set the fan speed on low for more comfort. The low speed on humid days will cool your home better and will remove more moisture from the air because of slower air movement through the cooling equipment. Consider using an interior fan in conjunction with your window air conditioner to spread the cooled air more effectively through your home without greatly increasing electricity use.

 

Set your air conditioner’s thermostat as high as comfortably possible in the summer. The less difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be. And don’t set your thermostat at a slighter setting than normal when you turn on your air conditioner. It will not cool your home any faster and could result in excessive cooling and, therefore, unnecessary expense.

 

  • Don’t place lamps or televisions near your air-conditioner’s thermostat. The thermostat senses heat from these appliances, which can cause the air conditioner to run longer than necessary.
  • In the winter, either cover your room’s air conditioner or remove and store it.
  • Proper maintenance of your air conditioner will also save energy. Be sure to do the following:
  • At the start of each cooling season, inspect the seal between the air conditioner and the window frame to ensure it makes contact with the unit’s metal case. Moisture can damage this seal, allowing cool air to escape from your house.
  • Check your unit’s air filter once a month and clean or replace filters as necessary. Keeping the filter clean can lower your air conditioner’s energy consumption by 5% to 15%.

 

Occasionally pass a stiff wire through the unit’s drain channels. Clogged drain channels prevent a unit from reducing humidity, and the resulting excess moisture may discolor walls or carpet.

Came to identify the issue and replaced the unit the same day. They were very professional, courteous and efficient. They keep good records once they work on your house so they were already familiar with the issues. These guys are definitely keepers. We'll absolutely go to them again.

Second time in less than 3 months that I’ve used these guys on 2 separate units. Both times issues were quickly diagnosed, explained, and after multiple courses of action to remedy were presented the fix was performed efficiently and professionally. Very fast response as well.
