"Two visits and that's not our fault: Brian came, diagnosed the problem (capacitor if not blower died, and tune up). He was right: a new capacitor made it work well, until the old blower just refused to obey. Two days later we called and said that Brian was right: the blower needed replacement. Doing just the capacitor was our call to try to save money. Now our 20+ year old furnace runs like new. And I'll be calling them to replace our HVAC ('cuz it's 20+ years old) when it decides to give up the ghost."

"I hired Capital Heating &Cooling for air duct cleaning. The technician, Garrett, was very friendly, explained everything he was going to do, and clean up was great. The one thing I didn’t like was the aggressiveness of their sales team. They continue to text, call, etc. until they hear from you."

"Hired to clean my dryer vent. I will say the tech who showed up was very nice and he even took his shoes off when he came in. He cleaned my vent from the outside in (which I thought was strange) because I was told he would do this**the technician will disconnect the vent from the dryer machine itself , and then from the inside-out he will clean the vent from lint and everything inside with specially designed equipment only for the dryer vent. If possible he will clean the outside of the vent as well ( If it is not too high in the air exit )** So he actually didn't disconnect the dryer from the inside first, he actually had it turned on while he cleaned it from the outside. 1. I could hear it running and 2. I could hear the alert it makes when it turns off). I could see everything blowing out and all over the place outside, also I heard a loud noise but then nothing so I figured it was just part of cleaning, about 10 minutes later the tech calls me downstairs, the dryer is now disconnected and he told me he found all these broken plastics pieces just inside the vent where the dryer connects. He has no Idea at all what happened or what the pieces are. I go upstairs and google and it looks like the blower wheel broke apart. The tech now reconnects the dryer and turns it on and it makes a loud noise, He says "maybe it's unbalanced" I mean really??! I mean maybe the piece would have broke anyway (dryer 8 years old) but at the very least admit it happened. He had the dryer on previously while he was cleaning and it sounded fine. So anyway I pay him because he did clean the vent, I want to pay CC , he suggests venmo, I say cc is fine , he says he'll have to charge me a percentage for fees, I told him I didn't care, so he goes to put thru card then all of a sudden says he just got a text and the system is down so I have to pay another way...Ok..LOL. So he leaves and I looks outside and there was Lint everywhere! I told him he didn't need to go crazy picking up every piece but he didn't pick up anything, All over my bushes, grass, blew up to my deck. The more I thought about it I decided to email the company with pictures, told I would hear back Tuesday. They wanted to send the tech back so I could explain what he didn't do?? then they gave me this explanation**** *** Technician said that he cleaned your dryer vent from both sides. From the inside - out and from the outside - in. When he touched the hose from the inside out , he found plastic pieces inside of the vent, which he reported right away to you . He believes that those pieces were from a dryer blower ( plastic blowers are rare and this probably means that it needs to be changed ) . Those pieces were already there , generally he doesn't touch the machine itself at all which means he couldn't cause those pieces to be there. As for the mess, he says that he picked up like 95% of it , but because it is kinda picky small stuff and the dryer vent was clogged a lot, so the smaller portion of it was probably blown by the wind around the bushes . He says also that you have seen him how he looked after that and he told you that because of that clogness the blower was putting too much force and probably got overheated and that caused those broken plastic pieces. That is what he said , if you want to have a word directly with him please let us know, or suggest what we should do. Thank you.**** I mean the plastic pieces were already there?? he cleaned up 95 percent?? and I'm the one who told the tech what I thought the pieces were!?? Honestly a manager/owner should take responsibility for his employees and not go back and forth with a customer. Also they state they are BBB accredited and they are not. I advise people to look elsewhere."

"Shane was able to schedule a prompt appointment. He arrived on time and performed a thorough diagnostic on the furnace. He identified an issue I was unaware of and corrected the problem with the air conditioner using parts that were still under warranty. I will gladly use his services again."

Air Conditioning questions, answered by experts

Most AC repair technicians will take between two and six hours to carry out repairs, depending on the work needed and the accessibility of the unit. For example, recharging refrigerant lines should take one to two hours to service, while replacing a compressor, blower fan, or other major components can take five to eight hours. You can ask your AC repair technician how long they expect the job to take, but just in case, you should plan on being home and available for most of the day.

No, it isn’t necessarily bad to turn your AC on and off frequently—contrary to popular belief. Even if you stop and start your AC throughout the day, it won’t use as much energy as it would if you ran it nonstop. 

If you’re concerned about your power consumption and energy costs, there are a few simple ways to use your AC more efficiently. Regularly cleaning the filters, scheduling routine maintenance, and using a programmable thermostat are all great choices.

To find a reputable HVAC company, start by researching providers in your area. Look for companies with mostly positive online reviews and check the Better Business Bureau’s website for customer complaints. Next, verify their credentials. Rule out any companies that aren’t licensed, as this is a requirement in some states and municipalities, and confirm they are insured. Once you have a shortlist, contact each professional to ask key questions: How many years of experience do you have? Do you hold any third-party certifications? Do you have experience working on my specific type of HVAC system or brand? Can you provide references? What is your per-hour pricing? Do you offer maintenance contracts for ongoing savings? Do you provide a warranty for your work?

Yes, it’s important to turn off your AC sometimes to give it a break and prevent it from freezing up. If your AC runs all the time, your system’s parts will wear down quicker, which may mean that you need to replace it sooner. Plus, using your AC constantly uses more electricity and leads to higher energy bills.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.
