"Max & Joe came out to our house and were not only professional but also very pleasant to host in our home. They made the entire experience prompt and pain free. While bringing a good amount of great advice for our air quality it was evident they knew exactly what they were doing and delivered on their promise of great quality service. Will definitely be calling Better Air for our next service."

"I had several companies bid on the project and the sales rep from Integrity Air was the only one to go under the house to check all issues and found one of the ducts disconnected and 'heating' the crawl space. Integrity Air's bid covered several options and was competitive. The installation crew was on time, courteous and efficient. The project passed inspection with no issues. All in all, I would recommend Integrity Air."

"Mark called me the same day I made the request for quotes/bids. He was on time for the in-home evaluation and provided a detailed estimate/proposal within a few hours. Mark is a straight shooter and gave me several options along with explanations as to what was gained or lost at the different price points. He was also very kind regarding other estimates and helping me to verify I was comparing apples to apples. The job was scheduled sooner than I anticipated, which was nice. His crew was on time and began removal before Mark arrived on sight to work with them and supervise. His workers were very professional and mindful of my overly curious cat that seeks to escape at any opportunity. The entire job took a day to complete from beginning to end and they hauled away the old equipment and scrap. The AC now blows nice and cold for the first time in about 10 years. After years of window A/C units, I had forgotten how great (and quiet) a properly installed and functioning central air system is. I highly recommend Mark and his business Air Control Systems for any HVAC work you may have. They have earned my business for as long as I live in this area. Thanks guys- Great job!"

"The bad air in that room has been a problem since I moved into the house and it has been hard to diagnose the problem. I am very grateful to Jim and Robert for their perseverance in figuring out how to approach this. The solution proved to be adding both the HRV and new thermostat, as well as adjusting the heat ducting. Now the air quality is very much improved and the heat is balanced throughout the house, where before it was either too hot or too cold upstairs. Robert is indeed a heating expert who also provided excellent tips for efficient operation of my furnace."

"Fast, efficient service. This Co. has worked on my furnace/AC for years. Only co. I have used. I was given a choice of 3 models, from $250 - $475, and opted for the most expensive, as that is the model being replaced. Thought (KNEW) the price was TOO high, but needed to get my system back on line in the current heat wave, and was desperate. My fault (caveat emptor) for not checking cost BEFORE they came. Checked after and found exact same MODEL for LESS than $150.00. Columbia charged me $325.00 more for the same control. I am never going to use them again, and suggest that you get bids from other cos. before you use them."

"Just wow! Our ducts were in a horrible state, probably never been cleaned and partially buried under the dirt in our crawlspace. There were massive leaks and even in our dinky house the air flow could hardly be felt out of the vents, and what did come out was filled with dust and who knows what else considering the varmint problems we've experienced in the past. The team came out on a Saturday which is huge so I didn't have to take time off of work, and a job that seemed to me to be pretty big only took 3 guys 2 hours start to finish!! The air current coming out now is so strong that our curtains move- something I have not witnessed in our home in 6 years; and the temperature in our back rooms are within a degree of the main living space now instead of being a freezer. I cant wait to start saving money on our heating and cooling bills while also being comfortable in our home, and I also look forward to not having to dust everything multiple times a week and suffering from less dust allergies. I am so grateful for the fast and great work Jesus and his team accomplished for us and it was surprisingly affordable. Thank you!!!"

Air Conditioning questions, answered by experts

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.

While your AC unit may still run even if its capacitor is going bad, doing so takes a lot more energy, so it can drive up your electric bill and cause further damage to your AC unit’s parts. If you suspect a bad capacitor, it’s important to have a professional diagnose and fix the problem before you continue to run your AC.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.
