AC THERMOSTAT SETTINGS: 10 IDEAL SETTINGS YOU SHOULD KNOW Best temperature while you’re away 85-88°F. Turning the thermostat up will keep the heat and humidity under control while you’re away, and also help you save on cooling. Turning your system off is OK if you don’t have anything in your home that would be at risk of overheating (pets, plants). HOW TO FIX INDOOR LEAKS Clear out and inspect the pan. Use a wet-dry vacuum to clean the drain pan after inspecting it from all sides using a flashlight. Use a water sealant. You can try to fix the drain pan temporarily using a water sealant. Replace the drain pan. It’s usually best to WHY DO AIR CONDITIONERS FAIL IN SUMMER? Understanding these reasons and how to detect them can help you identify and remedy issues with minimal hassle. Here are 6 reasons why ACs sometimes fail during the cooling season: 1. Fan issues. Most AC units contain two fans: one to blow indoor air over the evaporator coil, and another to expel warm air by blowing it over the condensercoils.

VRF. VRF or Variable Refrigerant Flow takes air con to wholly new heights. It’s an extremely sophisticated technology that basically operates on the same principle like the multisplit system. The crucial difference is that one outdoor unit can support as many as 48 indoor units.

If your air conditioner is tripping the breaker in your home, there could be a number of reasons, but the most common causes include: Loss of refrigerant. Frozen evaporator coil.

In short, these type of systems do not protect you from blackouts. DO I NEED A BATTERY BACKUP SYSTEM FOR MY SOLAR PANELS The simplest answer for this question is no, you do not need a battery backup system for your solar panels. A solar electric system works just fine without a storage system. In lieu of a storage system, a grid-tied solar electric system simply uses the grid to supplement anypower it needs.

WITH OUR 44+ YEARS OF EXPERIENCE, YOU ARE IN GOOD HANDS WITH ACTION AIR CONDITIONING & HEATING OF SAN DIEGO. REPLACING OR INSTALLING×
DID YOU KNOW?
HVAC costs make up for 48% of your energy bill * One degree of temperature adjustment can save you 1% * You can save 10% on your HVAC costs annually with a brand new replacement hvac system. WHAT’S WRONG WITH MY OLD AC, HEATING UNIT, OR FURNACE? Not all HVAC systems are efficient. Old furnaces or heating systems, or even boilers, were not created in accordance with today’s high energy conservation standards. And now, they are likely running higher costs on your bill each month then necessary. YOU’VE NOTICED YOUR ENERGY BILLS ARE TOO HIGH. If you’ve noticed a spike in your energy bills, it may be time to think about replacing or installing a new furnace or heating system. Many San Diego households are getting by with heating or AC systems over 10 years old. Like everything, heaters, furnaces, boilers, even your stove, must be replaced as the years go on.WINTER IS HERE!
Let’s restore your home to that cozy temperature with a new furnace or heating system that will make the holidays just a little bit less stressful! Nothing is better than sipping hot cocoa on a cold night surrounded by family and friends.DUCTLESS MINI SPLIT
×
Using a ductless mini split in San Diego is ideal as it draws hot air directly from the unit inside your home and then pushes it out side. If the temperature is cooler, it can reverse direction keeping the home at a nice cool temperature. Some of the positives around this are: * No duct work required * Energy efficient for hot or cool weather * Cost effective maintenance (installation is a bit more pricey) * Size of the AC/heating unit is compact * Total control of the home. You can cool or heat one room at atime.
* Improved air quality – indoor air is often lower in quality than outdoor air despite this being San Diego. Cons of a Ductless AC/Heater Unit * Installation Costs – Mini split systems are around 25-30% more expensive than traditional furnace, heating, or AC systems. * Location Calculations – If the contractor doesn’t properly locate the mini split systems, it can result in short-cycling which defeats the purpose in the first place. It’s crucial to use a certified HVAC contractor like Action Air Conditioning & Heating to properly place these systems. * The way it looks – Some homeowners in San Diego don’t like the way the heating/AC unit or system looks on their wall. It can be bulky in certain circumstances. In this case, replacing the traditional central air, heating or furnace unit may not be the best choice foryour home.
FURNACE OR HEATING SYSTEMS×
Nothing is more frustrating when it gets cold at night (yes, even in San Diego we have a winter!) and the furnace or heater unit unexpectedly just stops working. Heating systems or furnaces are something we take for granted in our daily life much like your oven orstove!
Unfortunately, repairs and service are a part of life but they don’t need to be a hassle! With over 44+ years in the business, Action AC & Heating can provide you with a timely and affordable service to get your heating system back up to speed! While many times repair or service is certainly possible, it’s often better to upgrade to a new heater or furnace. Unlike in the past years, furnaces today are much more energy efficient and will end up saving money in the long run. WHEN DOES MY FURNACE OR HEATING SYSTEM NEED TO BE REPLACED? Today’s furnaces can last up to around 15-20 years. But if your older, less efficient model is nearing the 15-year mark, it’s time to start thinking about replacing or installing a new furnace. THE ROOMS IN YOUR HOME ARE ALTERNATING TEMPERATURES As your furnace or heating unit ages, it can start to get inefficient to the point where it can’t evenly heat the rooms in your house. STEADILY INCREASING BILLS (REPAIR AND MONTHLY) This is a clearcut sign that your furnace or heating unit is starting to give out. Older systems have to be active longer to produce heat. As a result, that repair bill may come more frequently than you’d like to keep the old system going. With today’s modern HVAC units, due to the reduced monthly bills, you will often save money even with the cost of replacement. ISN’T THIS ALL EXPENSIVE? Replacing a heating or furnace system can be pricey. But there are several financing options we offer for San Diego homeowners backed by a very long warranties. Due to the current economic expansion in the US, there has never been cheaper or more affordable time to install or replace a new furnace or heating system.
