When to Call for AC Repair Services?

Don’t wait until your AC unit stops working to call for repairs. By being proactive, you can prevent further damages and save money on costly repairs.

At DG Heating & Air Conditioning, we recommend that you schedule an AC repair in Daly City if you notice any of the following signs.

Signs your AC unit needs repairs include:

• Warm air: If your AC unit is blowing warm air, it could be a sign that your refrigerant is low or your compressor is failing. Regardless of the cause, it’s best to call for repairs as soon as possible.
• Inadequate airflow: If you notice that some rooms in your home are cooler than others, it could be a sign that your AC unit’s compressor is failing.
• Leaking: If you notice any water pooling around your unit, it’s likely that your AC unit’s drain tube is clogged. A clogged drain tube can cause your unit to leak, which can lead to water damage and mold growth.
• Unusual noises or smells: If you hear any grinding, squealing, or banging noises coming from your AC unit, it’s best to call for repairs. Additionally, if you notice any unusual smells, it could be a sign that your unit’s wire insulation is damaged or that your unit has mold growth.
• Short cycling: If your AC unit is turning on and off frequently, it could be a sign that your unit is short-cycling. Short-cycling can be caused by a variety of issues, including a clogged air filter and a refrigerant leak.

Why Is My Heater Blowing Cold Air?

When the weather gets cold, the last thing you want is for your heater to blow cold air. If your heater is blowing cold air, don’t panic. There are a few reasons why this might be happening, and most of them are quick and easy to fix. At DG Heating & Air Conditioning, we can quickly diagnose the issue and provide you with an effective solution.

Common reasons why your heater is blowing cold air include:

• Thermostat settings: If your thermostat is set to “on” instead of “auto,” your heater’s fan will blow continuously, even when your heater isn’t producing warm air. This can make it seem like your heater is blowing cold air.
• Pilot light: If you have a gas furnace, your heater’s pilot light might have gone out. If this happens, your heater won’t be able to produce warm air. In some cases, you might be able to relight the pilot light yourself. However, if you don’t feel comfortable doing this, it’s best to call in a professional.
• Air filter: If your air filter is dirty or clogged, it can restrict airflow to your heater, causing it to overheat and shut off. If this happens, your heater will blow cold air. To prevent this from happening, it’s recommended that you replace your air filter at least once every three months.
• Ductwork: If your ductwork is leaking, your heater’s warm air can escape through the cracks and be replaced by cold air from your attic or crawlspace. If you suspect that your ductwork is leaking, it’s best to call for repairs as soon as possible. Leaking ductwork can cause your energy bills to skyrocket and put unnecessary wear and tear on your heater.

How to Choose the Right HVAC System

When it comes to choosing an HVAC system, there are a few things you need to consider. First and foremost, you need to consider the size of your home. If your HVAC system is too small, it won’t be able to keep your home cool or warm. On the other hand, if your HVAC system is too big, it will cycle on and off frequently, which can put unnecessary wear and tear on your unit and increase your energy bills.

Another thing you need to consider is your budget. HVAC systems can be expensive, so it’s important to have a budget in mind before you start shopping around. Additionally, you need to consider the energy efficiency of the unit. Energy-efficient HVAC units can help you save money on your energy bills and reduce your carbon footprint. Lastly, you need to consider the type of HVAC system that’s best for your home. If you have ductwork, a split HVAC system might be your best option. However, if you don’t have ductwork, a ductless mini-split system might be a better option for you.
