"From soup to nuts, the entire experience was made easy for us by the company. The salesman, Nick, came out to see us the day after my system kicked the bucket, and after checking out the system, he presented me with a few different options, and without using fancy words, explained everything plainly and easy for me to understand. After I discussed things with my wife, we called him a few hours later to give the go-ahead, and he had us scheduled just 2 days out. The installation team arrived promptly at the scheduled window, and took care to treat our house like it was their own. Drop cloths were used to protect my flooring, and after the job was done they made sure to remove all the debris from the job so nothing was left. After the job was done, the job foreman took me around and showed me everything that they did and explained the function of the system, and when I had questions, they explained plainly and without complaint or exasperation. They treated me and my house with the utmost respect. I highly recommend this company for any HVAC needs anyone might have."

Customers say: Quick response

"I cannot recommend this cleaning company highly enough! I hired them to do a deep clean on a three-story townhome to get it ready for the rental market, and they exceeded every expectation. Preparing a rental property is always stressful, but they made the transition seamless. Managing three floors of living space is no small feat, but the team tackled it with incredible efficiency and attention to detail. Here is what really impressed me: Flawless Attention to Detail: They didn't just do a surface wipe-down. They got into every nook and cranny, from the baseboards and window tracks to the inside of the appliances and cabinets. Tackled the High-Traffic Areas: With three floors, stairs can be a nightmare to get perfectly clean. They made the stairwells and banisters look brand new. Professional & Reliable: They arrived right on time, brought all their own high-quality supplies, and worked tirelessly until the job was done."

"Very well. Sunny's Services not only moved our new stand up freezer into our house, they removed the old one AND all the packing materials from the new one. They even advised us not to plug in the new one for a couple hours because they tipped it when they moved it. They were on time, courteous and the price was very reasonable."

Heating and Air Conditioning FAQs, answered by experts

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

A few drips here and there should not be cause for concern, but if your unit is leaking a large amount of water, then it’s advised that you stop using it until the problem is identified and a solution is determined. The more you use it during a leak, the more issues it will cause.

A power outage can damage your air conditioner, just like a power surge can damage any electrical device or appliance. In most cases, your circuit breaker or built-in surge protection on your AC unit protects your AC and just needs a reset. But in other cases, it might be that your AC compressor or capacitor was blown during the power surge. You’ll need to have an HVAC professional repair or replace any AC parts. 

Many factors affect how much adding air conditioning will cost you, from the size of your home to the size, type, brand, and installation specifics of the system itself. Chances are, a new central air conditioning system for a 2,000-square-foot house will cost somewhere between $3,900 and $7,900 to install, with an average around $6,000. 

Absolutely! You can seriously improve the overall value of your home by maintaining high-quality, compatible systems for heating and cooling. Potential buyers will love not having to worry about getting a new HVAC unit for 15 to 20 years and will pay more for it. For maximum efficiency and cost savings, replacing the furnace and air conditioner at the same time, when possible, gives you (and potential future buyers) reliable comfort and modern convenience.
