"Project went very well. My old air conditioner broke down in the middle of summer and the guys at Presidential made every effort to get my new unit installed quickly. They were very professional and I'm very happy with the workmanship. Great experience overall."

"My A/C stopped cooling on one of the hottest days of the summer. Corey from Hotzople Heating and Air Conditioning came out, did his assessment, explained in detail and showed me what needed repaired. A/C was up and running in no time. Highly recommend!"

"Everything went great. My AC died and it was close to 20 years old so I wanted the whole unit replaced. I have 4 young kids so no AC in the summer was not a pleasant option. The owner came out on site the day we called and was able to have the new unit installed the next day. I have dealt with many HVAC companies in the past as an Insurance Adjuster. These guys exceeded my expectations and were very reasonable on price. I highly recommend using Buric Heating and Air Conditioning!"

"I was lucky enough to have someone refer me to BlueStar Air Mechanical when my AC started acting up. The home warranty company confirmed that it was busted, but their mechanic was unreliable. After contacting a couple of other companies and having high quotes, I contacted Danny at BlueStar. The next morning (on a Saturday, nonetheless) I met Rhandel who quickly gave me a quote to replace my HVAC system (furnace and condenser). Rhandel was very nice and thoroughly explained my options. My home has two HVAC systems, so he also added a quote for the second system (which was on its last legs, too). The systems recommended were upgrades to what I had (increasing 1/2 ton on each system). To accommodate this, BlueStar included extra ductwork for me so that my house could accommodate. We met on a Saturday, agreed on a price on Monday, and everything was installed on a Thursday. They sent two crews and these guys worked hard for 12 hours straight to make sure both units were completed that day. I was very happy with their pricing and service. I have already recommended them to people I know in need of HVAC service. Pros: Pricing, options, promptness, service. Cons: 3% surcharge for credit cards"

"GAC services was able to come out for a same day trouble shooting appointment. Jim S arrived on time and was very courteous and professional. He was able to quickly identify the problem with the registers and dampers and able to get warm air flowing to the otherwise very cold areas of the house. In addition, Jim was able to recommend some additional services that would help me achieve the desired evenness of temperature such as an additional return and humidifier for the home. Great experienced master certified technician!"

"We had them Replaced furnace and air conditioning unit. It was installed about a year ago but they came out for a regular service about a month ago. the service was free, part of the contract. I have no complaints, it was all good. They were responsive. they were punctual. I have no problems, it was a good deal when I bought it, it's a good deal now. I don't have any issues with how the service went. i bought it through them and I have no regrets and everything was the same as I felt when I bought it. It was a good deal, I made the right choice. Anytime you buy a major system and it doesn't go right you have a problem. I'm a happy camper.1 worker took less than an hour to complete."

"Sean was very prompt in responding to me request for service and did his absolute best to accommodate my schedule at my convenience. He was very flexible overall and helped get my AC repair ASAP after it was broken. This was especially helpful since it was getting warm outside! He was on time for all of our appointments and communicated what needed to be done/fixed clearly, so I wasn’t left with a huge bill that I wasn’t expecting. Expectations are very important and he seems to understand. I would highly recommend Sean and/or his team for any issues you might have for a cost effective and friendly solution. Thank you so much for your help Sean!"

"Moises came out the same day that I requested an estimate for the installation of a UV light whole house air purification system, and to chemically clean my AC coil. I had another estimate but Moises gave me a better deal. He also recommended getting a cover for my AC unit for the winter, when he opened it up it was full of leaves and debris. I am very satisfied with the work that was done and would highly recommend MSR."

Customers say: True professional

"I had the best experience with Hecomo Heating & Cooling. My house's AC/heating system stopped working all of the sudden and the temperatures at the time were 90 degrees and up. I was desperate looking into many different companies. Many of them, came over to my house and did estimates at ridiculously high prices. Luckily, I found Hecomo. They came to my house, did an estimate and were ready to install my AC/heating unit very quickly and at a good price. Also, the customer service was great. They were there for me throughout the whole process. They explained to me everything that I needed to know about the system and the features. Everything is very modern and updated. I am very happy I found Hecomo."

Air Conditioning questions, answered by experts

Yes, high-efficiency models reduce environmental impact with lower energy use.

Signs that your A/C system needs professional service include increased energy bills, uneven or poor cooling, loud or unusual noises, and frequent cycling.

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

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 difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.
