"Reliable, honest service, and fair prices. They just did a two-system replacement for us and it went extremely well. I've been working with Robby and his team for over 10 years on behalf of third-party clients and he is one of the most trustworthy contractors I've known. When I moved to the Atlanta area two years ago it was a no-brainer to hire R Wiley for my home's yearly HVAC maintenance package and I'm glad I did. We've had Miguel, one of R Wiley's outstanding technicians out for service and maintenance and I've been happy with his work and helping to diagnose issues. When it came time to replace our very old AC & Furnace units, there was no sales pressure - just consultative solutions. R Wiley's pricing was in line with some of the more affordable bids and they don't try to push you into super high-priced marked-up units or things that should be included with installation, or all those "financing" programs where you end up paying way more for your project. Installation with Marvin was awesome - they were done with two units in one day and what a difference it's made. Overall an awesome experience from day one, with a successful multiple unit replacement. I'm glad I have them to continue to keep the units serviced on an annual basis as well. Highly recommend!"

"Update from 20 Jan 2026: I`ve been a repeat customer of Keep Smiling Plumber, Electrical, Heating and Cooling in the past for several home-related repairs. After having an unfortunate experience with Keep Smiling PEHC during my most recent service, I had some misgivings about the company and whether I would return as a customer. In regards to their customer service, everyone that I`ve engaged with (technicians, onsite supervisor, receptionist) has always been professional and courteous which goes a long way with me. The issue that I had was technical in nature and left me with some dissatisfaction regarding the quality of work. After speaking with leadership of this organization Mr. Powell and Ms. Amy ,I believe that they hold the highest standards and expectations for their employees and ensure that any work-related issues are duly addressed/resolved. I can sincerely say that they have regained my confidence and trust in contacting them in the future for my future HVAC, Electrical and Plumbing home needs. The manager I spoke with told me that there wasn`t any way the damage of the pump could come from the technician doing a drain and flush of the water heater. He told me that it would cost $1200 to replace the pump on the water heater. After speaking with the manager at Keep Smiling, I called another company which I`ve seen before in the community and spoke with a plumber and explained to him what happened. The technician at the other company told me that the pump could definitely be damaged if the pump was still plugged up and not turned off while the water heater was being drained and flush. I called the manager at Keep Smiling and shared those details with him and he replied that he understands what I`m saying but there was nothing he could do about it. I told him that I don`t have any reason to lie about any of this and felt very frustrated and cheated by the fact that I went in expecting for them to do a maintenance check for $59 for plumbing but ended up spending a $1000 for new.

"There was very little work to do. They came out on time and I was happy for the professionalism, but there was nothing to do because it's a brand new system. The service is free for a year. I could have had them come out in April to check the air conditioning system, but since they just installed the unit in April, I didn't bother, but it would have been free. This fall, when I called him to check the furnace, he thought he was coming out to check the air conditioning, I said, "no, you're here to check the furnace because I'm going to be using the heat this fall". He said, "no problem" and he checked that out, he said, "I feel like I'm not doing anything, I can still check the air conditioner", and I said, "if you want to, but I've been running it all summer and it's been great". I asked him there was a charge and he said, "no, the first year was free"."

This photo shows the new 3-Stage Water Filter System we installed for the client to resolve the bad smelling and bad tasting water. The system we installed has a stainless-steel drip tray to manage the water spilled during filter replacements. The Filters are bolted to the support beam to ensure it is not going anywhere. The photo also shows the shoe cover station we created to help maintain the quality of the vapor barrier and keep everything clean.
This photo shows the newly installed comfort system for the client. We love metal ductwork and its anti-microbial properties; however, the client did not want to replace the rest of the duct-board-air-boxes with metal at that time, but as you can see in the photo, we have made sure that can be replaced at a later date without any modifications to the system we installed. This system passed all of our performance checks and has since performed above the client's expectations, especially with hum

"Armato Heating and Air and Brent Weiss oversaw the recent purchase and install of a Daikin Mini split unit in my mid century modern renovated ranch house sunroom. The financing option Armato Heat and Air offered was very helpful, communication with the installers and speed of the installation was impressive. And the new unit- amazing! The room cools in record time. But the fine point of the attractiveness of the piping and tubing was what I like the most. Brent and Dylan cleaned up the clutter of cords and tubing from the unit that was replaced to get it down to very clean and simple lines. I am so pleased with the whole job. I really recommend this company for HVAC needs."

Install Boiler questions, answered by experts

The best time to buy home heating oil is in the summer when the demand is lowest, as the prices are usually lower. However, waiting until the summer to buy is often unavoidable unless you install a separate storage tank. If you have the space for a second tank, you can expect to pay between $1,000 and $4,000 for the oil tank replacement or installation, depending on the capacity and location. You could quickly recuperate these costs, though, by stocking up on heating oil in the summer and avoiding deliveries in the winter when prices are highest.

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.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.
