There IS A DIFFERENCE in duct cleaners. Most only clean "some" of the system, but DUCTZ Cleans the entire system including the Air Handler, supply and return ducts, and all components in the duct system. We are NADCA Certified (National Air Duct Cleaners Assoc) Air duct and Dryer vent Cleaning. DUCTZ is dedicated to making every home a cleaner and healthier place to be. We care about your home and respect it in every way. We don’t just clean ducts, we restore air conditioning systems to peak cleanliness. Our cleaning procedures are in full compliance with the industry standards from NADCA and ACCA. Not all duct cleaners are alike. Our techniques involve far more than simply air whipping your ducts. Ducts are fully brushed with brushes suitable for the ductwork being cleaned (see photos for the huge difference brushing makes over just using air tools). We take before and after photos as part of our process, assuring that all ducts are thouroughly clean. We are experienced and professional HVAC Air Duct cleaners, Ventilation System inspectors, and also perform quality Dryer Vent Cleanng serving Baltimore, Harford and Cecil Counties in Maryland. We are members of, and certified by NADCA (National Air Duct Cleaners Association) specializing in HVAC units and duct work: Certifications include "Air System Cleaning Specialist" and "Ventilation Sytem Mold Remediator" and certified Ventiliation System Inspector (ASCS, VSMR, CVI) from NADCA.

Estimates are free, as they are an expected part of cleaning using the right methods and at the right price. When you want to breath easy, and live healthy, call DUCTZ. 410-692-9775

"We are having our HVAC replaced and our salesperson recommended DUCTZ. DUCTZ came out on-time today to clean our air vents. The communication prior to the visit was very clear and it was easy to understand the upcoming process. They were very considerate, we toured our home and they went right to work bringing in the needed equipment and moving necessary furniture to access the vent covers. They were diligent and stayed focused on the task. Before I knew it, they were reattaching the cleaned vent covers and removing the equipment. Within a few hours, we had before/after pictures and have a great sense of comfort knowing all the gunk is gone! I highly recommend DUCTZ!"

"My chest freezer broke down and I did not want to buy a new one since I could not afford the same size. I reached out to appliance parts pro and they were confident that what I ordered would fix my problem. $200 in parts later and I now have a broken freezer on my porch and am still paying the loan to this terrible company. They just want you to order parts and try them because they know you can't return them.

At American Heating and Air Conditioning, we know all too well that heat pumps, furnaces, boilers, and air conditioners don’t give any warning before they decide to stop working. Part of our commitment to our customers is to provide round-the-clock emergency service. That means someone is available for a repair call 24/7. If you wake up to a freezing house to discover your furnace or boiler is not heating, you don’t have to wait till morning to call us for help. If you call in the middle of the night, we’ll be there ASAP to get it up and running and make your home comfortable. If you are a "service customer" of American Heating and Air Conditioning, there is no extra charge for emergency, after hours repair calls. If you live in the Bel Air area or surrounding cities, give American Heating and Air Conditioning a call. We may not be the biggest heating and air conditioning company in town, but we can guarantee we’ll treat you right and charge you a fair price for you repair, maintenance, and installation. We strive for 100% customer satisfaction.

"Josh came out and gave us an estimate. He checked over our existing system and had good ideas. He got back to me with written prices in just a day and we decided to hire him. We scheduled the work and they came on time and installed both systems in just two days. We are pleased with the workmanship and we love the mini split system on the second floor. American was great to work with."

"I contracted Level Home Services through Costco for a full A/C and furnace replacement and have been satisfied with their service at every point so far. The initial inspection to get a quote was extremely thorough and informative, and they gave me several options at different price points, all of which beat the other vendors I was looking at. When it was time to actually complete the work, the technicians were prompt, professional, helpful, and courteous. After 2 full days of work, they walked me through everything they did in detail and answered all my questions. By the time they left, the only sign anyone had been here was the shiny new equipment in my basement and yard -- no mess/dirt anywhere (except my own). It was a big job so it was pricey, but definitely money well spent and I would not hesitate to hire them again."

Your quality of life IS our business.

"In 2017, I contracted with them via Pepco because the 2nd floor rooms were hotter than the rest of the house, costing me greater A/C expenses. I worked with them on an energy audit to the upstairs bedrooms, removal of the acoustic ceiling tile in one room, addition/improvement of insulation, sealing in kneewalls, installation of new ceiling, insulation in the basement, and a follow-up energy audit. The auditor was very prompt and friendly but the workers didn't do an good job. The contractor was flaky. The HVAC crew were sloppy. The drywall installer/carpenter did a low-grade job by using low grade wood for the knee wall doors, and he set the ceiling inappropriately for house settling (now there are cracks between ceiling and walls). The energy audit following the work showed improvement but I'll need additional solutions to get the house to a more efficient state. I shared my disappointment with them and in 2018 they refinished cracking drywall ceiling without charge and replaced the doors - still not quality. They were bought by Minnick's, with whom in 2019 I scheduled an estimate for additional HVAC solutions for the upstairs. Minnick's jerked me around, never gave a complete estimate (I had to keep asking if it included what we discussed) and the estimate was exponentially more pricey than others and they proposed a solution that wouldn't solve the problem. I wouldn't recommend them at all."

Heating and Air Conditioning questions, answered by experts

Yes, a frozen AC unit can affect your indoor air quality since the reduced airflow won't be as effective at removing air pollutants, like dust and other allergens. Additionally, ice around the unit can create excess moisture, leading to mold and mildew that can damage your home if you don’t catch it early.

There are plenty of different not-so-great sounds to hear from your air conditioning unit, like squealing, grinding, water running, excessive gurgling, banging, and clanking. Each of these sounds can indicate a different malfunction with your unit, so it’s important to have a professional assess the problem before it gets worse.

To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Next, find the “reset” button on your AC unit and hold it for three to five seconds. The unit should beep several times. If your air conditioner doesn’t have a reset button, leave the circuit breaker off for 30 minutes. Afterward, turn the power back on at the breaker and program the thermostat to “cool” to test the system.

The standard HVAC warranty is around five years. Still, many brands offer an extension to 10 years if you register the product within a specific timeframe, typically 60 to 90 days post-purchase or HVAC installation. Over the past decade, warranty periods have substantially increased, shifting from 3-5 years in the 90s to the now-prevalent 10+ year warranties. Both warranty types cover parts failing due to manufacturer defects, incurring no additional costs. Some manufacturers provide extended warranties surpassing the usual 15- to 20-year window, though these often involve extra fees. 

Yes, unfortunately, scorpions do come up through air vents on occasion if they’re not properly sealed. These pests are excellent at finding small openings and may use vents as a pathway to cooler areas inside, especially during hot weather. To prevent this, inspect your vents, seal any gaps, and install fine mesh screens where necessary.
