"When our AC went out on a Friday afternoon, we contacted our Home warranty provider who told us we would need to wait until Monday and the company they connected us to had a bad reputation. So we took matters into our own hands and contacted Rescue AC late on Friday night. We chose them due to the great reviews they have online and they lived up to them. As promised they had someone out to our house early in the day and didn't give us long ridiculous windows of time. Roman was assigned to us, called us as soon as he was on his way and arrived exactly when promised. Roman was awesome: friendly, personable and super knowledgable and help us understand not only the problem but also things to consider and think about related to condition of our AC unit and options for the future. The best part NO HARD SELL, just lots of good info. He stayed to ensure the AC was running (and we talked Star Wars and geeked out a little together while we waited) Loved the invoice form with clear, all inclusive pricing, no fine print and no "mystery" labor or service fees. We even signed up for the (no contract) year maintenance plan which paid for itself with the %15 we saved. Thank you Roman and Resuce Air for saving the day and for making it a pleasurable and satisfying experience."

"Ben at clean air pro services was prompt, professional, and personable. He showed me a before and after of my ducts, then showed me what he retrieved from my ducts. You won’t believe the amount of dust and crud that we breathe in on a daily basis. We also tried them out for our dryer vent cleaning. Again another professional and quality job. I totally recommend this company."

Customers say: Super punctual

"I recently hired Pure Air Ducts to clean the air ducts and dryer vent in my home, and I couldn’t be more satisfied with the results. From start to finish, they were professional, efficient, and thorough. The technicians arrived on time, explained the process clearly, and took great care to protect my home by covering the furniture. They were courteous and answered all my questions, making sure I understood what they were doing. The job itself was done with precision, and I noticed an immediate difference in the airflow and cleanliness of the air. They even showed me the lint build up in the dryer vent. The entire process was smooth, with no mess left behind. Overall, Pure Air Ducts exceeded my expectations. Their attention to detail, professsionalism, and quality of work make them an easy recommendation for anyone in need of air duct and dryer vent cleaning. I’ll definitely be using them again in the future!"

"We have 22 air conditioning units in our food processing facility, and on all the occasions we have requested them, they have worked out around the timelines we set up to not affect production. They cover up with plastic the machines we request, and clean themselves up after they finish. We highly recommend them to others who have similar needs."

Air Conditioning FAQs, answered by experts

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.

Yes. Your air supply should be balanced. The return and supply ducts need to maintain that balance, and this only occurs because an equal amount of air should be entering and leaving your HVAC system. Changes in pressure, extreme weather, and blocking vents with furniture or your stuff can make the air supply unbalanced and cause your home to get too cold or hot.

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.

Yes, AC coil cleaning is definitely worth it. Cleaning your AC coils ensures your AC unit will function efficiently for the long term. Dirty and grimy AC coils make your unit work harder to cool your home, resulting in higher electric bills. Additionally, having your coils professionally cleaned regularly will reduce the possibility of extensive maintenance and repair costs.
