"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."

"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!"

"Quickly diagnosed the central air conditioning system, and gave an estimate on the cost of recharging the refrigerant in the compressor. The system is a 14 year old Carrier unit. Albert also included some sealant that may plug up the slow leak of refrigerant that occurs every 2 years or so. Albert also, showed me how to adjust the damper to control the flow of air to the second and third floors of the house. The other company that arrived wanted to charge me $5,000 to repair the system or close to $7,000 to replace the AC system with new. I intend to call upon Magna Tech Temp Air, Inc when I'm ready to purchase a new HVAC system. Thanks again for taking the time to listen to my concerns. Well done!!!"

"Sean was great during his visit to fix our furnace. He met us right away on a weekend, knew exactly what was wrong and repaired it for a very reasonable price. He was so good we asked him on the spot to do our twice a year furnace/AC checkups. Can’t recommend him highly enough."

"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."

"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 got a new unit from them, the system is really good but the office is bad. It is when you call them for the check up, it is a pain to make an appointment. They call and cancel and I have already taken the day off, or they just don't call or show up. They finally come out but that was after I called twice and talked to the office manager and them trying to cancel again. Even though I had a credit on my account I had to pay. Initially it was suppose to be preventative maintenance, but he refused to do both heating and AC and only did once, so another guy came out and did the other."

Air Conditioning FAQs, answered by experts

Yes, HVAC zoning systems offer energy savings by allowing precise temperature control in different zones in your home. Rather than conditioning the whole house uniformly, these systems direct airflow where needed, preventing energy waste. Tailoring comfort to specific areas reduces energy consumption and lowers utility costs, making HVAC zoning an energy-efficient choice.

Florida rooms can have heat or air conditioning, although not all do. These rooms can be added to the existing HVAC system or use a mini-split system, or they may just use a ceiling fan or the breeze from the windows for cooling. Florida rooms with air conditioning often have glass windows to keep the cool inside instead of just mesh screens.

A dual evaporator coil is a specific design that allows the AC system to cool different compartments at different levels. It’s usually seen in refrigerators and similar appliances, but not in whole-house air conditioning systems. Talk with your AC technician about the best uses for a dual evaporator coil.

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.

If both your furnace and AC unit are more than a decade old, it may be a good idea to replace both of them. However, your furnace can last up to three decades, and your air conditioner can typically last up to 15 years, so consulting with a pro before deciding to replace both of them is best. If it’s before that time limit for each, you can fix many problems with repairs or just replace one.
