How a Faulty Thermostat Can Create AC Problems

Monday, May 20th, 2019


Do you usually think of your thermostat as a part of the HVAC system? Or do you consider it something separate, a basic control panel on the wall that you have to adjust occasionally when somebody in the house starts complaining about it being too hot or too cold?

The thermostat is a control panel, but it’s also an essential part of the HVAC system. The thermostat connects you to the air conditioner and blower fan, but it also monitors temperatures in the house to detect and regulate how the AC works. If a thermostat has faults, such as miscalibrations or lost connections, it can create a slew of cooling troubles in your home. Often, those troubles may not at first seem like they’re coming from the thermostat, although professional HVAC technicians can track down the source for accurate air conditioning repair in Bellevue, WA.

Ways to Minimize Air Conditioning Repairs

Friday, September 19th, 2014

As the owner of an air conditioning system in Seattle, WA, it is very likely that, at some point, you will need to schedule an appointment for repair. While there is no way to completely avoid ever having to make a repair to your air conditioner, there are some preventative measures you can take to help reduce the amount of problems you experience. It is important, though, to have a company you rely on for those times when you need repairs, and the trained technicians at S&L Mechanical are available to help you 24/7.

Ways to Help Minimize AC Repairs

While we don’t recommend performing your own air conditioning repair work, there are a few steps you can take to help minimize the amount and impact of repairs:

  • Change the filter regularly – a clogged air filter can cause a number of problems with your air conditioning system, including restricted air flow, strain to your system and potential breakdown. It’s recommended that your air filter be changed every 3 months to ensure continued effectiveness and to avoid problems.
  • Make needed repairs – are you ignoring the signs or sounds of problems in your air conditioning system? Operational issues usually don’t go away on their own, and typically get worse with time. Making needed repairs as they occur not only takes care of that particular problem, but helps reduce the chances of a secondary problem developing.
  • Schedule bi-annual maintenance – maintenance is one of the best ways to keep your air conditioning system running optimally while also preventing repair. During a maintenance appointment, your system is thoroughly inspected, adjusted, lubricated and repaired as necessary. Maintenance allows the technician to detect problems and fix them, rather than having these issues develop into potentially large and costly repairs.

Having to repair your air conditioner is part of ownership, but following the suggestions above can help you reduce the amount of repairs your system may need. Experiencing problems now? Call S&L Mechanical today and schedule air conditioning repairs in Seattle.

How Does AC Maintenance Help With Repairs?

Friday, August 22nd, 2014

Even if you own a top-of-the-line air conditioner, your system is not safe from repair needs. Air conditioners work hard over the summer, which means it may become damaged over time. But if your air conditioner breaks down suddenly, you may be without air conditioning when you need it the most. Air conditioning maintenance is a service that can help decrease your cooling costs and prevent sudden problems from occurring.

Let’s take a look at some of the steps of this important service and how it may help prevent repairs in the future.


During maintenance, a technician cleans various parts of your system including the indoor and outdoor coils. This is partly because dirty parts can decrease the efficiency of your air conditioner, but they can also cause damage to your system that may lead to the need for repairs. If dirt or debris infiltrates a motor, for example, it may overheat and break down. The cost of a maintenance visit may be offset by the money you’ll save on such repairs.


A technician will also make minor adjustments or repairs that may be completed quickly at no extra cost, including bent condenser fins or loose parts. Minor problems may end up damaging large components of your air conditioner. A loose fan blade, for example, may inhibit airflow to the evaporator. Low airflow can cause the evaporator coil to freeze.


At the end of the maintenance visit, the technician will inform you of any problems found in your system during inspection so that you can schedule repairs. It’s important to catch issues early on, because a failing part may affect other components of your system, leading to a whole-system breakdown. If the technician notices a problem early on, you can reduce wear and tear to your system by scheduling an appointment right away.

The end of the cooling season is near, but that doesn’t mean it’s too late to protect your air conditioner from breakdowns for the rest of the summer. Call the experts at S&L Mechanical for repairs or maintenance for your air conditioner in Seattle.

3 Signs of Low Refrigerant

Friday, August 15th, 2014

Air conditioners are often a necessity in the warm summer months and many homeowners will do anything they can to prevent their systems from breaking down. One of the most common problems with air conditioners is low refrigerant. Refrigerant levels may be low if the technician did not add the proper amount upon installation or if your system is leaking. Leaks may form from corrosion or loose connections along the refrigerant line. Insufficient levels may lead to a variety of problems, such as limited cooling, frozen coils, or compressor damage, so it’s important to call for air conditioning repair when you notice any of the following signs of low refrigerant.

Hissing Sounds

If your refrigerant is leaking, you likely won’t be able to see any signs, but you may be able to hear it. A leaking refrigerant line sometimes makes a hissing noise as liquid or gas leaks from a small hole or tear. Whenever you hear unusual noises from your AC, you should call a technician right away.

Reduced Cooling

The air conditioning process needs refrigerant in order to cool a home. Without the right levels of refrigerant, the AC may be unable to remove heat from the home, and you may not feel any cool air at all. Your air conditioner will continue to attempt to cool your home, however, which means it will use a lot of energy to run, costing you money every month.

Air Conditioner Won’t Turn On

Some air conditioners are designed to shut off when the refrigerant gets too low. However, don’t assume a breakdown is an easy fix. If your air conditioner stops running, it may also be a sign of a more serious problem, such as a broken compressor.

You should keep in mind that simply recharging the refrigerant does not address the source of the problem. Refrigerant leaks can lead to major damages in your system. If you believe you have low refrigerant or any other problem with your air conditioning system, call S&L Mechanical for air conditioning repair service in Seattle. Our experts will fix leaks and add the proper level of refrigerant to prevent further repair needs and keep your AC running smoothly.
