"I called R.Wiley, Heating and Air, and Leonard came out right away. Rather than immediately telling me that I needed to replace the system because it was so old, he searched first what the problem could be. He replaced a part, but it turned out that this was not going to work very well because my furnace was just too old. It helped a bit but it was only a temporary fix to keep the furnace going for a while longer. We then decided that I would have to replace the system. He did NOT charge me for the part or for the service call! The price he quoted for a new system, was very reasonable, and on top of that, he gave me a discount because I am a service contract client. Then, two days later, because of the very cold weather, my system decided to quit altogether on Saturday morning. I left a message on Leonards phone asking if they could come out the next Monday to install the new furnace instead of the Tuesday we had agreed on. He called me back a few hours later and told me that they had made some arrangements with the supplier of the furnace and that they would COME OUT THE NEXT DAY WHICH WAS A SUNDAY!!!! They installed the system on Sunday and in the evening my house was comfortably warm again! This is amazing service that you don't see very often! It made me bless the day I signed the service contract with R. Wiley Heating and Air a few years ago! I Can really recommend this company for its courteous, friendly, and professional service!"

"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

"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!"

Install Boiler questions, answered by experts

The cost of heating oil fluctuates rapidly based on supply and demand, but the average price is between $4.00 and $4.50 per gallon, which means filling a standard 275-gallon tank would cost between $1,100 and $1,240. Much like automotive gasoline, the price of home heating oil changes constantly, so the only way to get an accurate and current price per gallon is to contact a heating oil delivery company. Some companies also offer contracts with a set price that should be an average cost over the contract term.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

Probably not. Moving a boiler to a new location is a very different prospect from replacing it in the same spot, and significantly more expensive. Plus, boilers are typically carefully positioned in proximity to pipes and radiators when installed. Homeowners may want to move boilers to free up space, prevent freezing problems that have happened in winter, or solve a noise issue—but it’s a much more costly proposition.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

Depending on the size of your home and system, as well as any upgrades or add-ons you choose, it may take between three and five days to completely replace an existing HVAC system from start to finish. Your contractor should be able to give you an estimate before they begin the actual replacement.
