Nick VerhamTrustindex verifies that the original source of the review is Google. We have had an extremely poor experience with Automatic Climate. We had a maintenance service agreement plan with them. Our tech who performed the annual maintenance was great and professional, but the other techs and office staff were very frustrating to work with. Our HVAC stopped blowing cold air one week after our maintenance service. When the tech came out, I asked if it could be the blower motor and he said no. He then misdiagnosed the issue as a refrigerant leak and charged us $1500 for refrigerant and a leak test, which did not fix the issue. He also tried to upsell us on duct cleaning, even though our service one week prior had not indicated we had dirty ducts. Since he did not fix the system, we were without HVAC for an additional day and a half until a different tech would be available. The different tech was able to correctly diagnose and fix the issue, which was in fact the blower motor. I tried to call the office to discuss the billing for the work. I called 5 different times, each time having to explain my issue, and was told that someone would call me immediately. No one ever called me back and this went on for over a week and a half. Finally, I called and someone was able to explain the billing. They ended up charging us for the work that was required to fix the issue with no discount for the misdiagnosis, additional days without HVAC, or the MANY issues trying to get in contact with the office. The misdiagnosis was frustrating and mistakes happen, but the office is disorganized and poor at communicating with their customers especially when dealing with an issue. I would not recommend using Automatic Climate for HVAC services. Scot WirthlinTrustindex verifies that the original source of the review is Google. On time, efficient, polite, thorough

Thank you for your feedback! We're glad to hear that our team was on time, efficient, and polite during your service. Eric BarnumTrustindex verifies that the original source of the review is Google. I have worked with several HVAC co since moving to Midlo in ‘11. Automatic Climate quickly became our servicer. They have been fantastic. At the end of June ‘23, one of 2 outside air handlers began acting odd so we scheduled an appt. I was expecting the usual crew but was surprised when a lone professional came one, Antonio. I want to note several things. I always have questions. While working, Antonio was pleasant and professional and got the work done and answered all my questions. He also uptalked the company to the point I was thinking, “Should I apply for a job here? Wow!” Besides fixing what turned out to be nothing, he found a warranty issue that would have been so easy to hide the weekend before the 4th of July. He got it done. Through it all, on a 98 deg day, Antonio painstakingly went through everything when it would have been so easy to not. I wouldn’t have known. The ethic demonstrated is a credit to the company. I want to note both the excellent service and professionals, like Antonio, who work here. Thank you. Timothy FergusonTrustindex verifies that the original source of the review is Google.

Signs Your Duct Sealing Might Need Attention
DIY Checks vs. Professional Duct Sealing Verification
Simple DIY Inspections
The Limitations of DIY Checks
While these DIY steps can identify major, obvious problems, they have significant limitations:
- Inaccessibility: Much of your ductwork is hidden within walls, floors, and ceilings, making visual inspection impossible without demolition. Significant leaks often occur in these hidden areas.
- Small Leaks Add Up: DIY methods are poor at detecting numerous small leaks, which collectively can account for substantial energy loss. Proper duct sealing addresses these comprehensively.
- Quantification Issues: DIY checks can’t measure the *total* leakage rate. You might find *a* leak, but you won’t know if the overall system meets acceptable standards for duct sealing.
- Safety Concerns: Navigating attics and crawl spaces can be hazardous. Working near HVAC equipment also carries risks if you’re unfamiliar with it.
When to Call the Professionals
Professional Methods for Confirming Duct Sealing Integrity
Duct Leakage Tester (Duct Blaster® Test)
This is the industry standard for quantifying duct leakage. The process generally involves:
- Temporarily sealing all supply registers and return grilles throughout the house.
- Connecting a calibrated fan (the “Duct Blaster”) to the duct system, usually at the air handler or a large return opening.
- Pressurizing (or depressurizing) the entire duct system to a standard pressure, typically 25 Pascals (Pa). This pressure difference simulates the operational pressure within the ducts.
- Measuring the amount of airflow (in cubic feet per minute, CFM) required by the fan to maintain that standard pressure. This airflow measurement represents the total leakage rate of the duct system (often referred to as CFM25).
The results of this HVAC duct testing provide a precise measure of how airtight your ducts are. Technicians compare this CFM25 number against industry standards or local building codes to determine if the duct sealing is adequate. A test performed after air duct repair can confirm its effectiveness. Quality duct sealing results in a low CFM25 reading.

Maintaining Ductwork Integrity: Post-Sealing Tips
What Constitutes “Properly Sealed”? Understanding the Standards
Beyond the numbers, proper duct sealing also involves using the right materials and techniques. Reputable professionals like those at Automatic Climate will use:
- Mastic Sealant: A gooey substance applied generously over joints and seams. It remains flexible and provides a durable, long-lasting seal.
- Metal-Backed Foil Tape: Specifically designed for HVAC applications (like UL 181 tape). It adheres strongly and withstands temperature fluctuations.
- Proper Mechanical Fasteners: Screws or clamps at connections before sealing ensure structural integrity.
- Aerosolized Sealants (e.g., Aeroseal): An advanced technique where sealant particles are blown into the duct system under pressure, automatically finding and sealing leaks from the inside. This method often achieves very tight duct sealing results.
Conversely, plain cloth-backed “duct tape” should *never* be used for sealing ducts. It degrades quickly under temperature changes and fails, negating any duct sealing effort. Seeing this tape is a red flag. Effective duct sealing relies on correct materials and skilled application, often involving comprehensive air sealing techniques.
The Long-Term Benefits of Confirmed Duct Sealing

Taking the step to verify your duct sealing after a repair isn’t just about fixing a potential immediate problem; it’s an investment that pays dividends over the long term.
- Sustained Energy Savings: Properly sealed ducts minimize wasted energy month after month, year after year, leading to consistently lower utility bills and a quicker return on your repair investment. This is key to long-term improve energy efficiency.
- Consistent Home Comfort: Enjoy reliable heating and cooling in every room, eliminating frustrating hot and cold spots. Verified duct sealing equals consistent comfort.
- Healthier Indoor Air: By preventing the infiltration of dust, allergens, and pollutants from unconditioned spaces, effective duct sealing contributes significantly to better home air quality and a healthier living environment.
- Reduced HVAC Strain: An efficient duct system allows your heating and cooling equipment to operate as designed, reducing wear and tear and potentially extending its operational lifespan, saving you from premature replacement costs. Good duct sealing protects your HVAC investment.
- Peace of Mind: Knowing that your duct system has been professionally tested and confirmed to be properly sealed provides confidence that your home is operating efficiently and safely.
Effective duct sealing isn’t a one-time fix forgotten after repair; it’s fundamental to your home’s performance.
