He said he would come out the next morning between 8:00 and 10:00 am snd he was promptly on time.

Response from the owner: Thanks so much!
Zac and Giovanni are always extremely polite, considerate and professional. We are thrilled to have the new A/C unit. Our unit was 18 years old and stopped working in the thick of 100 degree weather. Tom (the owner) came over within an hour (after hours) and bought us time by changing out some parts until we could have the new one installed. We’re very happy with Thomas Hoffmann A/C and Heating!
Response from the owner: Katie, we're delighted that Zac, Giovanni, and Tom were able to assist you promptly and effectively during the heatwave. Thank you for choosing Thomas Hoffmann A/C and Heating!
Honest takes his time to listen and help you without charging Arm and a leg
Response from the owner: Thank you so much for your kind words, Carrie! We truly appreciate your feedback.
Couldn't be happier with our experience. Our AC stopped working after typical hours and they were the only "24/7" HVAC service who was able to come out same day. Not only were they fast, but they identified and fixed the problem immediately and did some preventative maintenance (and showed me how to do it) to prevent it from happening again. Will absolutely use them again in the future.
Response from the owner: We're so glad to hear about your positive experience, Hannah White! Thank you for choosing us and we look forward to helping you again in the future.
Great service! Prompt, polite and got the job done quickly.
Response from the owner: We're so happy to hear that you had a great experience with us! Thank you for your kind words.
Thomas Hoffman personally quoted the job at a fair price and they did a quality install! I would highly recommend them!
Response from the owner: Thank you for recommending us, Joe! We appreciate your feedback and are glad you were satisfied with our service!
Came same day and fixed the problem.
Response from the owner: Thank you for your feedback! Glad we could help you out the same day.
Caught in a bind one evening (no AC), I called for an appointment to get mine repaired. They came out the next morning, one half hour early! Within 30 minutes we back up and running!! Thank you, Thomas Hoffman. You are my guys!
Response from the owner: Thank you for choosing us, Sue! We're glad we could help you out quickly and get your AC up and running smoothly again! Thomas Hoffman and the team appreciate your kind words!
Blower went out on a Sunday. They answered my call, got me in, replaced blower, very easy!
Response from the owner: We're so glad we could assist you with your blower on a Sunday! Thank you for sharing your experience with us.
Thomas is amazing and came over in only a couple hours and fixed my ac! True life saver 🙏🏼
Response from the owner: Thank you for sharing your experience with Thomas! We're glad to hear he was able to help you out quickly and efficiently. 👍
Fantastic experience! Our AC went out on a scorching Saturday evening. I wasn’t actually expecting anybody to get out that night, but when calling - I immediately got an answer, was on the schedule in 5 minutes, and Thomas showed up an hour later. He was honest, professional, and educational. Most importantly, I didn’t feel like he was cutting corners or trying to get in and out… a welcome contrast from most services these days. 6 stars out of 5, highly recommend.
Response from the owner: Thank you for sharing your experience, Andrew! We're so glad to hear that Thomas provided such honest and professional service for your AC needs. We truly appreciate your recommendation and look forward to serving you again in the future.

Possible Causes

There are many reasons why your air conditioner filters are getting dirty quickly. Here are the top four culprits. 

  1. Cheap filters: Cheap filters tend to have shorter lifespans than high-quality filters. Take, for instance, the standard fiberglass air filters. These types of air filters are generally designed to last for 30 days. Therefore, if you notice that your air filters are gathering dirt fast, it may be due to the inexpensive and low-quality air filters you’re buying.
  1. High temperatures: When the outside temperatures become extreme, your air filter might begin to experience dirt problems. This is because, during extremely hot weather, more air is pushed through the AC system by the blower motor. As a result, the filters will capture more dirt and clog faster. 
  1. Contaminants in the Air: High levels of dust and debris put a strain on your unit, making your filters clog faster. An increase in the number of people in your home can also increase the amount of dirt being kicked up into your system.
  1. Leaking air ducts: The air ducts are responsible for carrying heated or cooled air around your home. If there are duct leaks, this will make your unit work harder and get dirtier faster.
  1. Mold: In some cases, moisture can transfer to the air conditioner, leading to growth and accumulation of mold on the air filters. Aside from slowing your system, mold can also cause health issues. 

Problems Caused by Dirty Filters

When your air filter becomes dirty, you may experience the following problems:

  • Overheating: When the AC filters are dirty, they may eventually cause your air conditioning system to overheat. This is because the system has to work harder to keep up. 
  • Inadequate heating/cooling: If your AC filters become clogged, reaching the desired indoor temperature levels can be difficult. Less air blowing through the system due to dirt and debris can, in turn, lead to uncomfortable warm temperatures in your home. 
  • Unclean air: If your conditioner is not working properly, the air inside your house will become stagnant, and this can cause poor indoor air quality. Poor indoor air quality has been linked to respiratory issues such as asthma and lung disease.

How to Choose the Best Air Filters for Your Home

Air filters are one of the most important components of your HVAC system. Your unit’s performance is directly influenced by what air filters you choose and how well you maintain them.

Here is a breakdown of the main types of air filters for your home and how to choose the right one for you. 

Types of Filters

Certain features and properties set apart different types of filters. To browse for air filters efficiently, you have to decide what kind of product your unit needs. Here’s what to keep in mind.

  • The Size of the Filters – Make sure to accurately measure or check the size of the old filters on your HVAC system. Only go with what the manufacturer recommends, as filters that are incorrectly sized will not perform properly. Atypical openings will need air filters in special sizes and shapes, as trying to adjust a standard one yourself can render it inefficient. 
  • The Materials Used – The variety of materials and styles you can find can make your choice difficult, especially if you don’t know what to look for. You might need a thicker and denser filter if you live in a house where more air is circulated. Most air filters are made out of fiberglass, as it’s one of the more affordable options. Eco-friendly materials are also available, especially for reusable filters that one can wash for maintenance.
  • The Style – Two of the most commonly found styles of air filters are: pleated and honeycomb. Pleated filters have a bigger surface area to process the air, allowing the filter to catch more particles and circulate the air easier. In addition to the pleated style, these filters often have an electrostatic charge, which traps the particles and makes them stick to the filter. The honeycomb structure is mostly seen in more affordable filters. The honeycomb cells are made with paper fibers, fiberglass, or textile fibers, filtering the dirty air through the flutes.

The above characteristics are the very basics of air filters for your home. Here is more information that you can check when looking for air filters for your home.

The MERV Rating

The MERV rating system (an acronym for the minimum efficiency reporting value) is a 1 to 16 scale that shows how effective an air filter is in filtering out particles.

MPR (Microparticle Performance Rating)

MPR rates the filter’s ability to keep out nanoparticles from the air (particles with a circumference smaller than 1 micron. For people suffering from dust, mites, pollen allergies, a system with a high MPR can drastically change the quality of their life.
