Frequent Questions
We believe an informed homeowner is a comfortable homeowner. Find honest answers to the most common heating and cooling questions in Southern California.
Air Conditioning
If your AC is blowing warm air, it usually means the compressor outside isn't running or you are low on refrigerant. During a Southern California heatwave, systems work overtime and expose hidden issues like clogged filters or failing capacitors. We check the airflow and refrigerant levels first to get the cold air flowing again without trying to sell you a whole new system.
An AC freezes up when there is restricted airflow or a refrigerant leak, causing the indoor coils to drop below freezing. This is very common in the Inland Empire when dry, dusty air clogs your air filters. The best immediate step is to turn the system OFF and let the ice melt, then check your filter. If the filter is clean, we can come measure your refrigerant levels.
Water leaking from your AC is almost always caused by a clogged condensate drain line. As your system pulls humidity out of the air, the water drains through a pipe that can get blocked by dirt or algae. We can clear that line quickly and make sure your drain pan isn't rusted, preventing expensive water damage to your ceiling or floors.
For the best balance of comfort and energy savings in Southern California, the Department of Energy recommends setting your thermostat to 78°F in the summer when you are home. If 78° feels too warm, try 74°F or 75°F while using ceiling fans to keep the air moving. Every degree you raise the thermostat can save you up to 3% on your Edison bill.
If your AC never shuts off, it might be undersized for your home, extremely dirty, or struggling against a massive heatwave. However, if it's running constantly and your house still isn't cooling down to the set temperature, you likely have a refrigerant leak or a failing compressor. We can perform an honest diagnostic to find out exactly why it's struggling.
In the Inland Empire, you should change your standard 1-inch AC filter every 30 to 60 days. Because of our dry climate, high winds, and occasional wildfire smoke, filters clog much faster here than in other parts of the country. A clean filter is the #1 way to prevent expensive breakdowns and keep your system running efficiently.
You can lightly rinse the outside of your AC condenser with a garden hose to remove loose dirt and leaves. However, do not use a pressure washer, as it will bend the delicate aluminum fins and ruin the unit. For a deep clean, it's best to have a professional safely remove the casing and clean the coils from the inside out using specialized solutions.
A mildew or vinegar smell usually means there is algae or mold growing in your indoor condensate drain pan, or your system is suffering from "Dirty Sock Syndrome." Because the inside of your AC is dark and damp, it's a breeding ground for bacteria. We can thoroughly clean the coils and clear the drain lines to restore fresh, healthy air to your home.
You should almost always leave your AC fan set to "AUTO." When set to AUTO, the fan only runs when the system is actively cooling or heating. If you leave it set to ON, the fan runs 24/7, which significantly increases your electricity bill and can actually pull humidity back into your home after the AC shuts off.
SEER2 (Seasonal Energy Efficiency Ratio) measures how efficiently an air conditioner uses electricity. The higher the number, the less electricity it uses. In California, state laws require all new AC installations to meet a minimum SEER2 rating to help lower stress on the power grid. Upgrading to a high-SEER2 unit can drastically reduce your summer cooling bills.
A loud buzzing noise usually points to an electrical issue, such as a failing contactor or a dying capacitor in the outside unit. A clicking noise can mean the system is trying to start but failing. Electrical issues can be dangerous and cause further damage to the compressor, so it is best to turn the system off and have us test the electrical components safely.
The cost to replace an AC unit in the Inland Empire varies widely based on the size of your home, the SEER2 efficiency rating you choose, and whether your ductwork needs repairs. Because we don't rely on high-pressure sales tactics, we offer completely free, zero-obligation quotes for system replacements. We prefer to visit your home, evaluate your specific needs, and provide a transparent, upfront estimate so you know exactly what to expect with absolutely no hidden fees.
Heating
If your heater is blowing cold air, it could be a dirty flame sensor, a broken ignitor, or an overheating issue caused by a dirty filter. For safety reasons, modern gas furnaces will shut down the burners if they detect a problem, but the fan may keep running. We carry replacement parts for most major brands and can usually fix this on the very first visit.
It is completely normal for your heater to smell like burning dust the first few times you turn it on in the winter. In Southern California, our furnaces sit unused for 8 to 9 months, allowing dust to settle on the heat exchanger. When the burners ignite, that dust burns off. The smell should dissipate within an hour; if it doesn't, give us a call.
Because Southern California winters are mild and the heating system is used less frequently, a well-maintained gas furnace can last 15 to 20 years or more. However, skipping annual maintenance can cause the heat exchanger to crack prematurely, which is a major safety hazard. Regular tune-ups are the best way to maximize the lifespan of your heater.
A gas furnace burns natural gas to create heat, while a heat pump uses electricity to move heat from the outside air into your home. Heat pumps are incredibly efficient for the mild winters in Southern California and double as an air conditioner in the summer. We can help you compare your SoCalGas and Edison rates to see which system makes the most financial sense for your home.
A loud bang when the heater turns on could be delayed ignition, where gas builds up before igniting. This is a serious issue that needs immediate attention. A clicking noise is usually a struggling ignitor. Never ignore loud noises from a gas appliance; we can diagnose the issue safely and prevent a small repair from turning into a major safety hazard.
General Comfort & IAQ
Uneven temperatures are usually caused by leaky ductwork, poor insulation, or an improperly sized HVAC system. Over time, flexible ducts in your attic can tear or become disconnected, blowing your conditioned air into the attic instead of your bedroom. We can inspect your ductwork and airflow to balance the temperatures throughout your entire home.
The best way to lower your energy bills is to change your air filters regularly, keep your outdoor condenser clean, and schedule annual maintenance to keep the system running efficiently. Additionally, upgrading to a smart thermostat and sealing any leaks in your attic ductwork can stop you from wasting money heating and cooling the outdoors.
To combat Southern California dust and wildfire smoke, you need a high-quality air filter and a well-sealed duct system. If your ducts have leaks, they will pull dirty attic air straight into your living room. We can seal your ductwork and install whole-home air purifiers or better filtration systems to keep your indoor air healthy and clean.
For most homes, a MERV 8 to MERV 11 filter is the perfect balance. It catches dust, pollen, and pet dander without severely restricting the airflow to your system. Using a filter with too high of a rating (like MERV 13+) can actually suffocate your HVAC system and cause the coils to freeze up, unless the system was specifically designed for hospital-grade filtration.
Yes, absolutely. Preventative maintenance catches small, inexpensive issues (like a weak
If your system is over 12 years old and the repair cost is more than 30% of the cost of a new system, it usually makes financial sense to replace it. However, if it's a simple fix, we will always offer the repair option first. We pride ourselves on giving you honest advice, not pushing you into a high-pressure replacement sale if you don't truly need it.
