"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."

"Mark and helper climbed their ladder outside to the Soffit under the roof overhanging. They cleaned the vent and ran a brush all the way down to the clothes dryer. Now my clothes are dry and the amount of dust has increased due to the opened pathway. Any dust that came outside was cleaned up. Great job. Thanks!"

Heating and Air Conditioning FAQs, answered by experts

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

Keeping your air filter clean is crucial for your heat pump's efficiency. As a general rule, you should check your air filter every 1 to 3 months. However, the actual frequency might vary depending on factors like the type of filter, indoor air quality, and the amount of dust and debris in your area. If you notice the filter is visibly dirty or clogged, it's a clear sign it needs attention sooner. Regular filter maintenance ensures proper airflow and helps your heat pump perform optimally, keeping your indoor air fresh and comfortable.

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.

The best way to save money on HVAC repairs is by regularly having your system inspected and maintained. This can prevent bigger problems and costly repairs and replacements in the future. It’s also smart to buy quality equipment and hire companies that provide warranties on equipment and labor. If you need repairs, you may be able to save money by cashing in on rebates and incentives or keeping the area around your HVAC unit clear to shorten the time your contractor needs to spend in your home.

Here’s the cost formula to find out how much it’ll cost you to run a window air conditioner in your home:  Watts * (hours used) / 1,000 * (Local kWh) = daily cost of running a window unit. If you need help calculating the cost of running your window AC unit, consult an AC repair or installation pro for an accurate estimate.
