"Danny treated me like an old friend with helpful and timely service. It was refreshing. He inspected the unit, found a failed capacitor caused by an add-on Michael and Sons installed last inspection. Danny replaced the failed part, removed the add-on, and I was back in business in less than 30 minutes. I have a new HVAC provider!"

"I called Buric (on advice of friend/neighbor) when A/C wasn't working and I asked what to expect in their charges. The guy on the phone told me they charge a flat $95 (or $99?) for driving out here. So I asked if they charge by the hour or half hour. No, he said, by the job. He couldn't give me an estimate because he didn't know what was wrong. So, a technician came out and diagnosed my unit (which blew air but didn't get cold) as old & dead and needing replacement. So, in my mind, there was really there was no job outside of replacement. In their mind, they did a job by taking 10 minutes to look at the unit and tell me there was nothing to be done for it. So, instead of charging me $99 for coming out, they charged me $230 for coming out AND telling me the unit couldn't be fixed. That irritated me. Then I asked for a bid for new system. The guy went out and talked on the phone to his boss and come back with a written bid. I later compared it with my second bid from another co. Buric's bid was higher than the company I selected, but not enough to sway me if I had liked their way of doing business. However, the previous (over)charge, which was not explained by the guy I spoke to when I first called, left such a bad taste in my mouth I couldn't go with them. So that extra $130 they made cost them around $5000. I hope it was worth it to them. BTW, if I had gone with them, they would have subtracted the $230 from the bid, but I just couldn't get past it. So, I am not saying anything about the quality of their work--it may be just fine, but I don't like the way they did business."

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."

"Professional, diligent, excellent communications and attention to detail, It's hard to find tradesmen who you can have confidence in, But Edwin has it all. We contracted Edwin's HVAC to replace our 22 year old AC system, he provided a very prompt quotation, with two other company's in the bidding one never responded the other took a week, Work was carried out 3 days after awarding the works, Edwin arrived at the door on time and without delay proceeded to remove the existing system 7hrs later the new system was in, commissioned and handed over carried out in a very professional and excellent workmanship. Ah! I didn't mention price... Edwin's quote was 2/3's that of the competitor and didn't suggest or recommend additional un-necessary work(s) Would I hire Edwin's HVAC again - Yes without a doubt..."

"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!"

"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!"

"Moises, the company owner, is incredible. I called 5 HVAC companies to get quotes for full system replacement, and MSR was not only the most responsive, but he came out the very next day. He gave me an incredibly competitive and fair quote for my project, and we immediately gave him our business. Unfortunately, our AC died before he could do the work, but he came out to our house at 6pm on a Friday to drop off a portable AC unit so we wouldn't sweat all night long. We thought we'd be stuck without central air for a few days, but Moises came and worked 9 hours on a Saturday to replace both our furnace and our AC unit. Afterwards, he even gave us a great price on a yearly HVAC maintenance plan. MSR is run by an honest, hard-working tradesman who understands what customers want and need. I won't hesitate to recommend him to friends or to anyone who needs HVAC work done."

Air Conditioning questions, answered by experts

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?

A frosty expansion valve that isn't blowing out cool air is a sure sign that it’s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.

Yes, adding central air can increase your home value by as much as 10%. Generally speaking, prospective buyers prefer a central AC system over a ductless system or room-by-room AC units. That’s because central air conditioning blends into the home easier than individual room air conditioners and typically has less equipment to maintain.

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.

You can protect your air conditioner in the winter by turning off the power at the thermostat and performing routine HVAC maintenance in the spring. Regular maintenance, cleaning, and repair of your AC unit helps protect it and extend its life span. If you have a window AC unit, remove it from the window and store it in a dry place during the winter. Window units cannot withstand freezing temperatures. Keeping them in your window also allows cold air to seep into your home.
