You may have tried to cover up indoor odors by spraying air fresheners or lighting candles. Unfortunately, these tactics only mask the odors, they don’t get rid of them. These remedies may in fact negatively affect indoor air quality from chemicals that cause allergic reactions or eye irritation for homeowners.

Bacteria, dust mites, animal dander, cat saliva and mold may also be roots of your home’s odor problem. One method to purify the air is integrating germicidal (UV) lights in your home, which helps kill odors and inhibit the growth of biological contaminants, sterilizing surfaces in the HVAC system. They also purify the air, preventing the growth of contaminants. The UV lights are installed to work with your home comfort system.

Sometimes poor ventilation contributes to unpleasant odors. Moisture condensation on walls windows and stagnant air are signs of poor ventilation. A qualified Service technician can inspect your home comfort system to determine if this is an issue that should be addressed. The technician can also inform you how to solve the ventilation system’s ability to correctly circulate and ventilate indoor air. Call us at 215-366-1001 for more information.

A few quick HVAC question tips:

• Clean and replace your air filters frequently.
• Your system will heat and cool more evenly when the blower is in the “on” position. The blower provides constant air movement throughout the home, and allows for better filtration. If everything works the way you want, “auto” fan mode would reduce energy consumption.
• Install shades, drapes, shutters, or screens on windows that are exposed to extreme sunlight to keep room temperatures at moderate levels.

For PECO electric customers rebates for heating and cooling are based on ENERGY STAR criteria, rated as a whole system by the Air Conditioning, Heating, & Refrigeration Institute (AHRI). Federal requirements and amount of rebates change based on the time of installation and ENERGY STAR, AHRI ratings, and the new federal SEER2, EER2, and HSPF2. You can find up-to-date answers to HVAC questions and apply on the PECO website, or by contacting our office at 215-366-1001.

Ionizers release electrically charged ions into the air to attach to particles and force them to stick to surfaces or collector plates. Some air cleaners also produce ozone, either intentionally or as a byproduct, to neutralize odors and pollutants. However, ozone generators are not recommended by the EPA for occupied spaces, as ozone can irritate lungs and worsen asthma. Always choose ozone-free air purifiers or models that produce negligible amounts within safety guidelines.

If you suffer from allergies, asthma, or notice lingering odors or visible dust in your home, an air purifier can be an effective solution. Homes in urban or high-pollution areas or with pets and smokers benefit most from a quality air cleaner. For best results, combine an air purifier with duct cleaning, regular filter replacement, and HVAC maintenance to maintain a healthy indoor environment.

Yes, many Carrier heat pumps qualify for federal tax credits and local utility rebates due to their energy efficiency. Check with your HVAC provider or local energy company for specific offers available in your area.

Adding air purifiers, humidifiers, or advanced filtration systems to your HVAC setup can improve indoor air quality. Regular duct cleaning and filter changes also help reduce allergens and maintain healthy air circulation.

Check the thermostat settings, replace the air filter, and ensure vents aren’t blocked. If the issue persists, it could indicate a problem with the furnace, heat pump, or ductwork. Schedule a professional inspection to identify and resolve the issue.

If you observe any unusual sounds, it is advisable to seek professional service promptly. Similarly, if your HVAC system is unable to regulate the temperature in all areas of your residential or commercial property, professional service should be sought promptly. If there has been an unexplained escalation in your utility bills, it may well indicate an underlying issue with your system. Delaying prompt attention to these HVAC questions or problems can worsen existing issues. Therefore, we advise you to schedule a service appointment with EMCO Tech Heating & Cooling without hesitation. Our experienced heating and AC contractors can provide a reliable diagnosis of the problem. They can also make the necessary repairs to prevent further damage and avert potential safety hazards.

There are a few signs that can help you determine if your A/C unit is big enough for your house. Some of these signs include your A/C not cooling your home, inconsistent room temperatures in your home, your air conditioner not turning off, high energy bills, high humidity levels inside your home, and low airflow in your home. Additionally, you can use an AC Size Calculator to estimate the proper Central AC size in TONs & BTUs based on your house size, SEER rating (Glossary page), conditioned space (house) size, heat load & loss, and other parameters. This calculator can also help you estimate the cost of installing your Central Air system in different climate zones (regions).

It’s important to note that bigger isn’t always better; it is performance and efficiency that count. Before purchasing a replacement system you should always make sure your system is sized properly to match your needs and budget. A service manager from EMCO Tech Heating and Cooling aka Emergency Maintenance Company will thoroughly assess your home and comfort requirements to determine the proper size and make the appropriate recommendation.

Common Questions About Air Conditioning Installation
Ensure That Your Air Conditioning Runs Efficiently

Loud HVAC equipment can contribute to sound disturbance, which can affect the comfort of the occupants. While lower sound levels may not always result in financial savings, the sound rating of a cooling system plays a crucial role in ensuring a pleasant and peaceful environment. Several factors determine the sound level of an air conditioner or heat pump, such as the unit’s make and age. The the AC compressor sound blanket can also affect the noise levels it generates. Therefore, it is vital to consider these factors when selecting a new HVAC system to ensure optimal comfort and minimal sound disruption. Contact our office to get a no obligation on-site quote and consultation.

Regular filter replacement helps your heating and cooling system operate at peak levels and improves indoor air quality. It is important to change filters regularly to ensure proper airflow and to keep your home free from dust, allergens, and germs.

To determine whether an existing warranty is in place for a furnace, air conditioner, or boiler heating system, one may refer to the label affixed to the exterior of the equipment to ascertain the manufacturing date. If the equipment is less than five years old, it may warrant coverage. However, this is subject to the model as well as the terms and conditions of the warranty, which can vary by both manufacturer and installation company.

Interested parties may contact EMCO Tech, formerly known as Emergency Maintenance Company for assistance in verifying the status of a heating and cooling system warranty. Office managers are standing by to provide support and guidance. Those who want to verify their equipment warranty status can complete and submit the Get Warranty form.

A HEPA filter (High-Efficiency Particulate Air filter) is a dense mechanical filter that captures at least 99.97% of airborne particles as small as 0.3 microns. These include dust, pollen, mold spores, pet dander, and even some bacteria. HEPA filters are widely used in air purifiers and HVAC systems to improve indoor air quality, especially in homes with allergies or respiratory concerns.

The MERV rating (Minimum Efficiency Reporting Value) is a scale from 1 to 20 that measures how effectively an air filter captures particles. The higher the MERV rating, the more efficient the filter is at trapping small airborne pollutants. For most residential HVAC systems, a MERV rating between 8 and 13 offers a balance of efficiency and airflow. Higher MERV ratings (like 16 or above) are typically found in hospitals or clean rooms.

Yes, Carrier systems are compatible with smart thermostats like the Infinity Touch Control and third-party devices like Nest or Ecobee, allowing you to control your heating remotely and optimize energy use.
