Most Common AC Problems and Their Causes
When your AC isn’t working the way it should, it’s not always easy to pinpoint the issue. That’s why it helps to understand the typical warning signs and their root causes.
Let’s break down some of the most frequent problems homeowners face with their cooling systems, and what might be happening behind the scenes.
Weak or Uneven Airflow
Santa Clara homes rely on steady, reliable cooling, but when airflow is weak or patchy, it can throw everything off. This issue often comes from clogged filters, duct issues, or aging AC units that need attention. Sandium’s team uses high-precision tools to diagnose and fix the problem, so every room feels just right.
Warm Air Coming from Vents
AC on, but still feeling the heat? You could be dealing with low refrigerant, a thermostat glitch, or ductwork that’s letting cool air escape. Whatever the reason, Sandium’s pros will find the problem fast and talk you through a fix that makes sense for your home and your budget.
Strange Noises During Operation
Unusual sounds during operation are often a warning. Whether it’s a loose part rattling around or a motor on its way out, catching these issues early can save you a major repair. Sandium’s deep experience in Santa Clara homes means we know what to listen for and how to stop it.
Water Leaks or Frozen Coils
Notice puddles forming or a layer of ice on your AC coils? Those are red flags for drainage problems or restricted airflow. These issues can quietly cause mold or water damage if ignored. Sandium’s skilled team gets to the bottom of it fast, so your system stays dry and running strong.
Unpleasant Odors When the AC Runs
Bad smells might mean mold in the ducts or burnt wires inside the unit. We offer indoor air quality services in Santa Clara, CA that eliminate odors and improve your home’s breathability with filtration, duct cleaning, and ventilation solutions.
Rising Energy Bills Without More Usage
This could be a sign that your AC system is losing efficiency with age or struggling due to hidden issues. Sandium’s pros can run a full audit of your system, identify energy drains, and help you upgrade to modern, money-saving alternatives.
Common Energy Leaks Found in Bay Area Homes
Older properties in Santa Clara, particularly those built before the energy-conscious 1980s, are prone to:
- Poor attic insulation
- Leaky ducts in crawlspaces
- Drafty windows and doorframes
- Gaps in exterior wall penetrations
Through our home performance auditing, Sandium helps homeowners uncover these issues and reduce long-term energy costs. We also help with rebate paperwork and financing options to make upgrades more accessible.
What an Indoor Air Quality Test Measures
Indoor air quality plays a big role in comfort and health, especially in Santa Clara, where dry summers and wildfire season can affect what’s floating through your home’s air. An indoor air quality test gives you a clear picture of what you’re breathing and how your HVAC system is performing.
Here’s what our team looks for during a detailed home assessment.
Particulate Matter
These include dust, dirt, pollen, and smoke particles. Santa Clara’s dry summers can elevate particulate levels, especially during wildfire season. We test and offer filtration systems that address these risks.
Volatile Organic Compounds (VOCs)
VOCs are the invisible offenders hiding in common household products, from floor finishes to room sprays. Poor ventilation lets them build up in your air. Sandium’s IAQ solutions help identify VOC presence and improve your home’s air quality through advanced ventilation and filtration.
Carbon Monoxide & Carbon Dioxide Levels
These gases can impact safety and comfort. We test for both and recommend smart monitors and HVAC adjustments when needed.
Humidity and Moisture Levels
Excess moisture can cause mold and mildew. Low levels can affect health and wood furnishings. We balance your home’s humidity to fit Santa Clara’s natural climate conditions.
Allergen and Pet Dander Concentrations
For families with allergies or pets, these pollutants can trigger symptoms. Sandium offers advanced air purification solutions to help you breathe easier.
Benefits of Professional Ductwork Repair Services
Instead of guessing where your airflow issues come from, we use diagnostic tools to pinpoint problems inside your ductwork. Our repairs focus on sealing joints, replacing damaged sections, and boosting insulation where needed.
Well-repaired ducts can:
- Improve airflow by up to 30%
- Lower energy usage
- Enhance indoor air quality
- Extend the life of your HVAC system
Our team is licensed, bonded, insured, and backed by P1 Service Group, which means you benefit from national warranties and elite technician training.

Comparing Ductless Mini Splits to Traditional HVAC Systems: Which Should You Install?
As energy costs rise and home designs evolve, so do the options for keeping your space comfortable year-round. Whether you’re upgrading an older system or planning for new construction, understanding the differences between ductless mini splits and traditional HVAC systems can help you make a smarter investment.
Traditional HVAC Installation
Best for large homes or those with existing ductwork. Offers centralized control, but may lose efficiency through leaky ducts.
We design and install traditional systems with performance, efficiency, and comfort in mind. As licensed general contractors, our installations meet high structural standards.
Ductless Mini Split Installation
Perfect for room additions, converted garages, or homes without ducts. Offers zoned comfort and high efficiency.
Sandium’s mini split systems are installed with precision and come with smart control options. Our team also handles heat pump retrofits for all-electric conversions, popular among Santa Clara homeowners looking to reduce fossil fuel use.
Signs You Need Air Duct Installation
Many homes in Santa Clara still have aging ductwork from decades past. If you notice excessive dust, uneven cooling, or poor airflow, it might be time to replace your ducts. We specialize in custom ductwork that maximizes comfort, matches your home’s layout, and improves energy efficiency.
With C-20 and C-2 licenses, Sandium can take care of everything from HVAC to insulation-related upgrades. Our factory-trained team builds every duct system to spec, sealing each connection to improve airflow and reduce waste across your entire system.
Frequently Asked Cooling, Heating, & Indoor Air Quality Questions
How long does a full AC replacement typically take?
Most replacements take one full day. Larger or more complex systems may require additional time, especially if ductwork or electrical upgrades are involved.
Can maintenance prevent refrigerant leaks?
Yes, regular tune-ups can catch worn valves or loose connections early. Our technicians are trained to spot potential leak points during service.
What does it mean if I smell gas when the furnace runs?
This could indicate a dangerous leak or combustion issue. Turn off the system and contact Sandium immediately. Our licensed techs perform thorough diagnostics and safe repairs.
Do my heat pumps need maintenance?
Absolutely. Heat pumps work year-round, so we recommend twice-a-year tune-ups, once in spring and again in fall, to keep performance high and costs low.
