HVAC stands for Heating, Ventilation, and Air Conditioning. It encompasses all the systems used to regulate indoor temperature, humidity, and air quality.

At Gillani Heating HVAC, we recommend replacing your HVAC filters every 1 to 3 months, depending on several factors such as the type of filter you're using, the air quality in your home, and whether you have pets. Regularly replacing your filters is essential to maintain optimal system performance, improve indoor air quality, and extend the lifespan of your HVAC system. For households with pets, allergies, or a high level of dust, more frequent changes, possibly every month, may be necessary. If you're unsure about the best schedule for your home, our skilled technicians can provide personalized recommendations during routine maintenance visits. From repairs to installations and everything in between, Gillani Heating HVAC is here to ensure your comfort and satisfaction.

A MERV (Minimum Efficiency Reporting Value) rating measures how effectively an air filter can capture airborne particles. The rating, which ranges from 1 to 20, is set by the ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) and helps determine the filter’s efficiency in trapping contaminants. MERV Rating Breakdown: • MERV 1-4: Basic filtration; captures large particles like dust, pollen, and carpet fibers. Used in residential window AC units and pre-filters. • MERV 5-8: Medium efficiency; traps mold spores, pet dander, and finer dust particles. Common in residential HVAC systems. • MERV 9-12: High efficiency; captures finer particles like auto emissions and some bacteria. Used in hospitals and high-quality residential systems. • MERV 13-16: Superior filtration; removes bacteria, smoke, and fine particles. Found in commercial buildings and hospital surgery rooms. • MERV 17-20: HEPA-level filtration; captures viruses, carbon dust, and ultra-fine particles. Used in cleanrooms and pharmaceutical facilities. Which MERV Rating is Best? For residential use, MERV 8-13 is ideal, balancing filtration and airflow efficiency. Higher MERV filters (above 13) may restrict airflow if the HVAC system isn’t designed for them.

Yes, smart thermostats can be a valuable addition to your home's heating system, and there are several reasons why you might consider installing one. Smart thermostats offer the convenience of controlling your HVAC system remotely through a smartphone or computer, allowing you to adjust the temperature settings even when you're not at home. This can lead to increased energy efficiency and lower utility bills, as you can program the thermostat to reduce heating when it's not needed and ensure a comfortable temperature when you return. Furthermore, smart thermostats can learn your schedule and preferences, automatically adjusting the temperature to optimize comfort and efficiency. They also provide detailed usage reports, giving you greater insight into your energy consumption and helping you make informed decisions to improve efficiency. At Gillani Heating HVAC, we believe in leveraging technology to provide the best possible service to our clients. Our experienced technicians can help you choose the right smart thermostat for your home and ensure it is installed correctly, optimizing your heating system's performance.

To keep your system running efficiently all year round, inspect, clean, or change air filters regularly in your central air conditioner, furnace, and/or heat pump. Your contractor can show you how to do this. Consult your owner’s manual or manufacturer’s guidance for how often you need to change the filters. Remember: a dirty filter can increase energy costs and damage your system.

7 Things to Check Before Calling a Furnace Technician If your furnace or cooling isn’t working the way it should, don’t panic—there are a few simple things you can check before calling a licensed technician. You might be able to solve the problem yourself and save time and money. Here are 7 things to inspect: Check the Thermostat Settings It may sound basic, but it happens more often than you think. Make sure your thermostat is set to “Heat” or "Cool" and the temperature is above for heating or lower for cooling than current room temperature. If it’s unresponsive or acting erratically, your thermostat might be faulty and may need to be replaced. Ensure the Furnace Switch is ON Look for a switch near your furnace—usually mounted on the wall or unit. It can resemble a light switch and may have been turned off accidentally. Flip it to the ON position. Inspect the Furnace / Air Conditioner Breaker or Fuse Locate your home’s electrical panel and find the breaker labeled for your furnace. If it’s tripped (in the middle position), turn it fully OFF and then back ON. If your system uses a fuse and it has blown, replace it with one of the same size. Repeated issues may signal an electrical problem that requires professional attention. Check the Furnace Filter A dirty or clogged filter can restrict airflow and cause your furnace to shut down. Inspect your filter and replace it if it’s visibly dirty or hasn’t been changed in a while. Clear Snow from Exterior Vents High-efficiency furnaces have intake and exhaust pipes that vent outside. After heavy snowfall, these pipes can become blocked, causing the furnace to shut down. Clear away any snow around the vent area to restore proper airflow. Ensure Access Panels Are Properly Reinstalled After changing your furnace filter, double-check that all access panels are securely reattached. Some furnaces have safety switches that prevent operation if the panel isn’t correctly in place. Check for Obstructed Airflow Make sure no furniture is blocking air vents or returns. Also, ensure that all supply registers are open. Poor airflow due to blockages or a clogged filter can cause your furnace to work inefficiently or shut down. Still Having Trouble? If these steps don’t solve the issue, it could be a more serious problem that needs professional diagnosis.

The size depends on factors like home square footage, insulation, and windows. Our experts can perform a load calculation to recommend the right unit.

With proper maintenance, most AC units last 10-15 years.

Common causes include low refrigerant, thermostat issues, or dirty filters. It’s best to have a professional diagnose the problem.

Furnaces typically last 15-20 years. Consider replacing yours if it’s nearing this age, requires frequent repairs, or has increased energy costs.

Unusual noises can indicate issues like loose components, a malfunctioning blower, or ductwork problems. Call a professional for a thorough inspection.

Schedule a maintenance check annually, ideally in the fall, to ensure optimal performance and safety.

Furnace ratings refer to the efficiency, performance, and capabilities of a furnace. The most important ratings include: 1. AFUE (Annual Fuel Utilization Efficiency) Rating • Measures how efficiently a furnace converts fuel into heat. • Expressed as a percentage (higher is better). • Example: A furnace with 90% AFUE converts 90% of fuel into heat, with 10% lost. 🔹 Standard Ratings: • 80% AFUE or lower – Older or basic models, common in warmer climates. • 90%-98% AFUE – High-efficiency models, often Energy Star certified. 2. BTU (British Thermal Unit) Rating • Measures heating capacity. • Example: A 100,000 BTU furnace can produce 100,000 BTUs of heat per hour. • Proper BTU sizing depends on home size, insulation, and climate. 3. ENERGY STAR Certification • Awarded to high-efficiency models that meet U.S. EPA guidelines. • Usually 90% AFUE or higher for gas furnaces. 4. ECM (Electronically Commutated Motor) Efficiency • ECM blowers adjust speed to improve efficiency and comfort. • More efficient than PSC (Permanent Split Capacitor) motors.
