"It was our third time using The Handy Veteran and it will not be the last. Kevin and his team are absolutely top notch! Our first job with Kevin was to replace and paint all of the wood and trim in our entire house, replace carpet with LVP flooring on a third of the floors in our 3000sqf home, refaced our fireplace, install a new front door, & paint the entire house. Second job was to repair and paint our large deck. This last job was to replace more floors, remodel our guest bathroom and hang multiple lights fixtures. Our first job was in 2020 and the initial work they did is still perfect. Kevin stands by his work. He is not satisfied until the job is done right and was extremely accommodating to all of our requests. He wanted us satisfied and happy with the work and even made some great suggestions that really enhanced the final outcome. Him and his team are extremely respectful of our time, professional, friendly and trustworthy. Also very fair with their pricing! "

"I had some backup into the basement, they came to rod it out and told me I needed to check the line going to the street and they could come back for a video check. Well they said they came back and took the video and I needed some expensive work to clear the line. I called to ask them for the video, they said that they'd have someone call me back. They called me back and said that there was no video, their worker didn't put in a USB drive and besides they said I didn't ask for one. What did they expect I was asking for??? I said I expected and wanted a video, how do I know they even really performed the work. They said they would call me back. THEY DIDN'T. I called them back, they again said they'd call me. Again no call. The last time they told me, the owner was on another call but would definitely call me back. One week later NO CALLBACK. I firmly believe they didn't do a video, charged me for one and took me for a sucker. I will NEVER use this company again. I think they are crooks. P.S. Ever since they rodded the drain one of my toilets started have trouble flushing. I won't doubt they messed it up so they could come back again for more money. DO NOT USE. P.P.S. I wonder if they will contact me on this posting, I doubt it."

Heating and Air Conditioning questions, answered by experts

Unfreezing an AC unit is not a DIY project unless the problem is a dirty air filter. Changing out an air filter is easy for homeowners, but otherwise, trying to repair ductwork, refill refrigerant, or replace a blower fan motor are tasks best left to the pros. Otherwise, you could cause further damage to your cooling system or even harm to yourself.

Some of the signs of HVAC issues include rising energy bills, rooms not cooling or heating properly, loud noises when in operation, and signs of condensation. To illustrate, if you’re wondering how to stop condensation on air vents, you’ll need to have your HVAC inspected. 

While it’s possible to only replace an evaporator coil to keep your AC running, this could cause issues down the line. An AC system relies on the harmony between its condenser and evaporator coils for efficient operation. Replacing only one coil, especially in older units, can cause compatibility issues, leading to inefficiency and potential system breakdown. 

As AC units near the end of their expected lifespan, investing in the cost for a new AC system is typically better than paying for individual component upgrades to avoid costly repairs and ensure optimal performance.

In most cases, you should hire a professional to carry out services on your HVAC system, as the components are complicated, expensive, and potentially dangerous to work with. However, there are a few things you can do on your own to keep your HVAC system in good condition, including changing your filters every three months, keeping the area around your outdoor condenser clear of debris and plant growth, making sure your or intakes aren’t blocked, and keeping an eye out for increased energy bills, strange noises, and unusual odors related to your equipment.

Replacing both an AC and a furnace takes a full day on average, ranging from eight to 12 hours. The process involves removing the old units, installing the new ones, and ensuring all connections are properly made. If both systems are being replaced simultaneously, it can take longer than installing a furnace alone, so plan accordingly.
