"BUYER BEWARE!!!! DO NOT USE THIS COMPANY IF YOU VALUE YOUR TIME & MONEY. Owner is extremely unprofessional. I have reached out to the company a total of 5 times. Before coming to this point of leaving this review. I am now out over $7.5k. I hired allen heating and cooling to replace my 26 year old AC and 10ish year old furnace on May 2022. They have since been out on 4 occasions to try to get it to function properly. Once in December of 2022 in which they turned up the blower motor and turned down the gas. Because my home was 50 degrees and wouldn't heat. Then 3 times from April-May because the AC cant reach temp. All 3 times with no explanation as to why my AC wasn't properly functioning. No leak. Added freon just to be safe. But no other explanation and after every visit they said they'd let Tom know. Following every visit I'd have to email and call the office and explain its STILL not working. During these visits my caps where left off my AC the first time as photographed. Damaging the valve which was discovered on the 4th visit on the exterior unit. My interior unit was never put back together right the last visit.. and after ALL THESE VISITS and missed time at work. I spent THOUSANDS of dollars for a HVAC unit that has functioned less then 50% of the time I've had it. The owner has not ONCE reached out personally to handle this issue. The front desk staff just continues to send out techs & Tom continues to not take responsibility for the poorly installed system his buisness put in. Not standing by his contract terms or "worry free guarantee". I have done my part. I use the cheapest filters. I have air deflectors. Weather stripping. Blackout curtains & a great thurmostat. My AC functioned perfectly prior and was only replaced due to age along with the furnace. There is no excuse why after over $7.5k I do not have a working HVAC system. The company needs to stand by their work and rectify the situation. The company also gives a nice little discount for any customers who leaves a 5 star review.... if u look at how many negative reviews they have and the argumentative replies from the buisness to anyone who has something negative to say... well.. I see why they have to do this. I have provided photos to show what I've gone through with each visit and documented as much as possible to share. I have tried to be nice and gave the company way to many chances. I'm all for supporting local businesses and thought that this was a truly reputable buisness to go with as a 23 year old woman at the time just wanting the best for my first home. However I can't help but feel like I've been completely taken advantage of at this point. So I hope this review saves others from being in my same situation."

Air Duct Cleaning questions, answered by experts

It is common for mold to grow around air vents, especially in areas with high humidity or moisture problems. These vents provide a perfect environment for mold to thrive due to the condensation caused by the meeting of warm and cool air. Mold growth can be accelerated by the presence of dust and debris around the vents. Regular maintenance, proper ventilation, and addressing any water leaks or excess humidity can prevent the growth of mold around air vents.

Mold in HVAC ducts is a relatively common issue that homeowners struggle with—especially in humid climates or homes with poor ventilation. Moisture from condensation, combined with dust and organic debris, creates the perfect environment for mold growth. Homes with high humidity, leaky ducts, or clogged drains are more prone to this issue. Regular inspections and proper HVAC maintenance significantly reduce the risk of mold developing in your ducts.

Air duct cleaning is always worth the money. Not only will it increase the air quality in your home but it can actually be a net positive over the long term if your vents are so dirty or damaged that they leak air. Cleaning or fixing them ensures the air you are paying to cool and heat actually reaches the livable space of your home instead of dissipating through the walls.

Smoke damage will not go away on its own, but with professional remediation and restoration, you can return your home to its original condition after a fire. Trained smoke restoration professionals can eliminate smoke damage, which can affect areas of your home that are hard to see or access, and restore or replace smoke-damaged materials.

For most homes, the common causes of poor airflow in a duct system are blockages, typically from dust, debris, or buildup. Other factors include leaky or disconnected ducts, improper duct sizing, and clogged air filters. These issues restrict airflow, reducing HVAC efficiency.
