"Technicians were very professional and did a great job of cleaning the dryer and 18 vents, as there has been a very noticeable change in the air flow. We had a few rooms where there was hardly any air coming from the AC but after the vent cleaning the rooms now get improved air flow and are able to cool down. Will definitely use them again."

"Tyler Jones from All City Plumbing Air and Electrical did a great job replacing a gas valve in our garage. He was friendly and easy to engage with, clearly knowledgeable, and took the time to explain what he was doing. The work was completed efficiently and effectively, and everything was handled professionally from start to finish. I’d definitely recommend Tyler and All City for plumbing and gas-related work."

"We had Temp Air install our AC unit. The best decision we ever made. They were fast, reliable and dependable. Excellent customer service, did a phenomenal job. After a couple of years something was going on with our unit, I called them and immediately they send out a technician Juan, who was phenomenal. He explained what the issue was and resolved it asap! Highly recommend this company!"

"My least favorite part of owning a home is paying for it. That's probably true for most people, but I find it very difficult to part with a dollar. For that reason, about 10 years ago, when my air conditioning died, I told my family we were going to live without it - I grew up without air conditioning and did just fine. About 2 years ago, the furnace started to give us a little trouble as well, and this year, before the winter started in earnest, it died too. Both systems dated to 1977 (I bought the house in 2005). As soon as the cold weather kicked in this past year, I knew I was going to have to have everything replaced. The extreme cold this year, plus the unreasonably hot summer in 2022...well, it was time to fix things. I got on Angie's list to find some contractors. I stuck with people with 5 stars (or as close as possible) and over 100 reviews, and had about 8 different outfits come by to look at the job and give me bids. It took a while, but when you are looking to have to spend 25-30,000 dollars, you want to make sure it doesn't go to waste. I found that, even with 5 stars, a company might not be too impressive when they come by to look at a job. One company tried to hard sell me with fancy brochures and pressure tactics. Another opened up our discussion by saying that he "refuses to pull permits - it saves us both money," and that he insisted on installing a furnace that did not comply with county emissions standards, because "it'll be nothing but problems if you follow the rules." Gustavo, from GC Heating and Cooling, struck me as a cut above the rest of the guys that showed up. First off, the first thing he wanted to do was see the current system himself, despite being the owner of the company and not a young man. He and I climbed into the attic - the fact that he invited me to check it out was cool - and after he saw everything, we sat down to talk. He was patient and kind - I felt like he was excited about doing the job, excited about how he could improve the situation of our house, and he wanted to communicate that excitement to me. I told him what we wanted to do, and he gave me several options to accomplish the goal - of course, as a professional with a college degree in mechanical engineering, he had an opinion about which was the best option for us, but (and this is a testament to his honesty) crucially, his "best" option was not the most expensive option. After we were done talking, he gave me a very fair price (I base my opinion on the other estimates I got), told me that no matter what happened on the job he would not increase the price, and told me to call him if I liked what he had to say. Let me make this long story a little bit longer - I chose Gustavo to get the job done, and I'm grateful to him and his crew for getting the job done in as excellent and efficient a manner as I could have hoped. His crew is clean and polite, and they work quietly and quickly, always cleaning up after themselves. Any time I pointed out a problem, they fixed it. Any time I had a question, they answered it. To be honest, these guys were so cool, it made me not want to go to work on the Friday they started the job so I could work with them and maybe learn something! They wrapped up a full HVAC job, removing all of the old equipment and installing the new, in a 2400 square foot house, in two and a half days. The whole time, Gustavo was running the show, keeping tabs on his guys, making sure things were running smoothly, and always answering all of my questions. On the final walk though for the job, when everything was done, he was still excited about the work, showing me all the different stuff he and his crew had done. Believe me, I was glad to shake the guy's hand and thank him and his team for a job well done. Gustavo's secret, if you ask me? He likes people, and he likes helping them out. He's got a lot of energy, and he directs it in a very positive way. All of that, and he's an expert in his craft. My recommendation to you, dear reader, is: hire Gustavo for your HVAC needs. I'm sure glad I did!"

"I highly recommend this company. Penguin heating & Air was very quick to respond to my request, fast text reply, sent them pics, they replied with a quote, which was way lower than anyone else on this site, or even our regular guy that we normally use, we scheduled an appointment for the very next day, which was today, he also finished the job the same day! David did a very good job, very professional. Despite a terrible rainy day, he got the job done. When he was done he walked me through with exactly what he did. He also quoted me for a service on an existing unit and his quote was almost $200 less than what our regular guy charges us... We will absolutely be using this company again."

Air Conditioning questions, answered by experts

After a while, dust, dirt, and other debris accumulates on an AC unit's coils and filters, making it less efficient and spreading allergens and other air pollutants throughout your home. Cleaning your AC unit will keep it running efficiently, minimizing future breakdowns and improving your indoor air quality.

The simplest indicator is how long it’s been since your last tune-up. You should schedule an annual AC tune-up each spring. Beyond that, there are multiple signs that your AC needs a quick check by a professional. These issues include higher-than-average energy bills, decreased air flow from vents, higher indoor temperatures, and an air conditioning unit that stays on all the time or frequently turns on and off.

A frozen coil can cause permanent damage to your HVAC system and lead to costly repairs if not fixed. It can cause the unit to overheat and also cause the compressor to fail. It’s vital to turn the unit off if the coil is frozen and address the issue as soon as possible. 

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.

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.
