0 stars if I could. Bought a faulty (not to mention overpriced) surface igniter, called back five minutes later after installing, of course they didn’t stand behind their part. Go to Grainger instead. Same (working) part, half the price.

Your service technician was very professional and knowledgeable. And did not appear to try to give me bogus information. I truly appreciate his honesty because several other companies did not appear to be honest, obviously wasn’t honest, my gut feeling told me they were not honest and tried to get me to spend $10,000 for a problem that was much simpler to fix. I look forward to you servicing all my properties, and possibly those of the rest of my family.
Response from the owner:Thank you so much for the kind words and great review! We appreciate your support.

⭐️⭐️⭐️⭐️⭐️ If I could give 10 stars, I absolutely would.

Last night our furnace went out unexpectedly, and with three kids in the house, the temperature dropped fast. Giovanni went above and beyond in every way possible. Instead of charging me a late-night service fee, he simply asked, “Are you decently handy?” and offered to walk me through some troubleshooting steps to get our heat back on so my children wouldn’t have to sleep in the cold.

Not only did he guide me through the process, he even FaceTimed me and showed me exactly what to take apart, how to put it back together, and what signals to watch for. It felt like having a real technician standing right next to me the entire time. Thanks to him, our heat was restored within minutes.

In a world where true customer service is hard to come by, Giovanni is a rare find. It is a guaranteed fact that any future repairs, maintenance, and the new heater/AC system we’ll be needing this coming summer/fall will absolutely be done through him. His honesty, kindness, and expertise have earned our business for life.

Highly, highly recommend.
Response from the owner:Thank you, Jeff, for sharing your experience! We're so glad to hear Giovanni was able to help you and your family during that tough situation. Your recommendation means a lot to us, and we appreciate your trust in our services for the future!

In today’s world, where indoor air pollution is a growing concern, home air purifiers have emerged as essential appliances for maintaining clean, healthy indoor environments. Home air purifiers are designed to remove harmful particles, allergens, odors, and pollutants from the air, improving indoor air quality (IAQ) and promoting better respiratory health.

At Thomas Hoffmann Air Conditioning & Heating, we prioritize customer satisfaction. From the moment you contact us to the installation and ongoing support, we strive to provide exceptional customer service. Our friendly and knowledgeable staff can answer your questions, provide guidance, and ensure a smooth and hassle-free experience.

Air Purifiers

Air purifiers are generally portable devices equipped with filters and fans that work together to capture and remove harmful particles from the air. They effectively eliminate allergens, odors, smoke, and other common pollutants. Air purifiers employ different filters, such as HEPA (High-Efficiency Particulate Air), activated carbon, and electrostatic filters, depending on the specific contaminants they target.

Whole House Air Purifiers

Whole-house air purifiers are advanced systems designed to clean and purify the air throughout a house, ensuring optimal indoor air quality. Unlike standalone air purifiers that only target specific rooms, whole-house systems are integrated into the existing HVAC system. This integration allows for a centralized approach, purifying the air in every corner of your home.

Since whole-house air purifiers are connected to the existing HVAC system, they leverage its power and infrastructure. This makes them more energy-efficient than multiple standalone air purifiers running simultaneously in different rooms.

Air Filtration Systems

While air purifiers provide localized air cleaning, air filtration systems offer a whole-house approach to improving IAQ. These systems are installed in your home’s HVAC system and are designed to clean the air. Air filtration systems typically use a combination of pre-filters, HEPA filters, and sometimes activated carbon filters to remove a wide range of contaminants. By integrating with your existing HVAC system, air filtration systems ensure that every room in your home benefits from cleaner and healthier air.

Benefits of Air Purifiers and Air Filtration Systems

  • Improved Indoor Air Quality: By removing allergens, dust, pollutants, and other harmful particles, air purifiers and filtration systems significantly enhance the IAQ in your home, reducing the risk of respiratory issues and allergies.
  • Odor and Smoke Elimination: Air purifiers with activated carbon filters effectively neutralize unpleasant odors and eliminate tobacco smoke, cooking smells, and pet-related odors.
  • Allergy and Asthma Relief: HEPA filters, commonly found in air purifiers, capture allergens like pollen, mold spores, and pet dander, relieving allergy sufferers and those with asthma.
  • Enhanced Respiratory Health: By reducing airborne bacteria, viruses, and other pathogens, air purifiers contribute to a healthier respiratory system and help prevent the spread of infectious diseases.
  • Peaceful Sleep: Air purifiers with quiet operation modes ensure a relaxed sleep environment by minimizing noise disruptions while cleaning the air throughout the night.

Factors to Consider When Selecting a Home Air Purifier

At Thomas Hoffmann Air Conditioning & Heating, we offer a range of high-quality air purifiers to help you achieve optimal indoor air quality. With over 30 years of experience in the HVAC industry, we have the knowledge and expertise to provide top-notch air purification solutions.

We will help you choose the right air filtration system for your home or business. Some of the factors to consider before purchasing a system include:

  1. Filter Type: The filter used in an air purifier is crucial in determining its efficiency. HEPA filters are highly recommended for their ability to capture small particles effectively. Activated carbon filters are beneficial for odor removal, while pre-filters can help extend the life of the main filter by capturing larger particles.
  2. Room Size: Consider the room’s square footage where the air purifier will be used. Different models have varying coverage capacities, so choosing one that matches your room’s size for optimal air purification is essential.
  3. Clean Air Delivery Rate (CADR): CADR is a measurement that indicates the cleaner’s ability to remove pollen, dust, and smoke from the air. Look for a purifier with a CADR rating appropriate for your room size and desired air purification level.
  4. Noise Level: Consider the noise level of the air purifier, especially if you plan to use it in bedrooms or other quiet areas. Look for purifiers with noise-reducing features or specific sleep modes for silent operation.
  5. Maintenance and Filter Replacement: Check the air purifier’s maintenance requirements, including how often the filters need to be replaced or cleaned. Ensure that replacement filters are readily available and reasonably priced.

Investing in an air purifier from Thomas Hoffmann Air Conditioning & Heating is a proactive step towards cleaner, healthier indoor air. With our advanced filtration technologies, odor-elimination capabilities, and whole-house air-purification solutions, we can help you create a comfortable, refreshing indoor environment. Contact us today to let our experts assist you in choosing the perfect solution for your air purification needs. Breathe easy with Thomas Hoffmann Air Conditioning & Heating!
