It may still be warm in RVA, but winter is just around the corner. As the cold weather moves in, air conditioning units will be turned off and heating turned on. Even though your AC has worked well throughout the hot summer season, there are still a few things you should do before you forget about it for the next few months. The G-Man has a few tips on how to winterize your AC:HVAC outside in snow

1. Change your filters. Just because your system is off does not mean debris will not be building up on your filter. Imagine not dusting a table for 4 months. There would certainly be a lot of dust. The same thing will happen to your AC filters. You don't want the first blast of your AC next year to be filled with dust and allergens.

2. Keep it clean. Even when not in use, you don't want debris or weather to block your system. If you have central air conditioning, make sure sticks, leaves and other debris are consistently cleared from around the unit. For both windows and ground units, you do not want too much snow to build up on your system. While the units are weatherproof, it is not good for moisture to sit on the unit for a long period of time. 

3. Protect your unit. When possible, take window units out and store them in a safe place. For central AC units, you can use a protective cover to protect from debris and other elements.

4. Clean coils. Just like the filters, you do not want the coils to get dirt build-up. Clean your coils before putting your unit to bed for the winter and it will run more efficiently at the first sign of warm weather.

If you have any questions about winterizing your unit, give us a call!


hvac-new homeSo, you made the leap and went from renting to buying! Congratulations. Now what? The hard part begins. Before you close on a house you want to make sure the HVAC unit you just bought along with that cute new house is in good shape.

The G-Man has a few tips to help you out:

1. Look at the unit. This may seem obvious, but visually inspecting the unit is important. If it looks dirty or rusty that means the current owners have not taken good care of it. While you are looking the outside unit, make sure to look for any leaks. On the inside, check out the air filters. If they are filthy, they haven't been changed in a while and the system is not running at peak performance.

2. Figure out the age of the unit. It is okay to ask questions. This is a big purchase you are making. An HVAC unit has a typical lifespan of 15 years. 

3. Check out the SEER rating. This has to do with how energy efficient the system is. Check out to see if the system has a good rating.

4. Run the system while you are in the house. Does every room feel cool? How long does it take for the system to get up to speed? All of these questions can be indicators to how well the system is working.

 Bonus: If you are unsure, have a qualified professional come check out the system for you.     

It has been a HOT summer in Richmond. We hit 100 degrees over the weekend and it surely won't be the last time. With these hot temperatures, your air conditioning may have some trouble keeping up. Here are a few quick and easy tips to keep your home nice and cool on these warm days:air conditioning service

1. Change the filter. Dirt and grime can block the air conditioning unit from doing its best work. If it looks dusty or discolored switch it out. Your home will thank you!

2. Check that all the ducts are connected. Overtime ducts can become loose and may become disconnected. Make sure that all your air ducts are fully connected.

3. Check for cracks or air leaks. You don't need to air-condition the outside. Make sure all windows and doors have a tight seal to keep all your cool air inside.

4. Shade your unit. If possible, place your unit in the shade. Your unit will run more efficiently if it is placed in a nice cool spot.

5. Call a professional. If you feel like your unit is not performing at its best, give us a call. Our trained technicians can do an all-points inspection to insure your unit is running at maximum capacity.

Summer has just begun and RVA is already feeling the heat. With temperatures well above 90 degrees, are you prepared?

The G-Man has a few tips for surviving the summer in Richmond:

Hot Summer-Air Conditioning

  • Use your blinds. Keeping your house shaded is key to keeping those air conditioning costs lower. Don't allow that hot sun to creep in by closing your blinds during the hottest parts of the day.
  • Make sure your air conditioner is running at maximum efficiency. We see it over and over, without regular checkups, your AC falls behind and doesn't keep you as cool as it could. Call us today and schedule a maintenance check. Your energy bill will thank you.
  • Bring water with you wherever you go. Don't get stuck outside without some H2O. Our bodies need more water to stay hydrated when it is hot outside. 
  • Find a shady spot to park in. Sure, the shade may be at the back of the parking lot, but it will pay off when you get back in your car a few hours later. If left in the sun, your car can reach up to 172 degrees. Also, never leave children or pets in a car, even if it's only for a minute!


The temperature is rising in RVA and we hope these tips will help you out.

Gilman Bros Heating Plumbing Old PicturesOur President, Winston Hancock, talks about celebrating 100 years with Gilman.

"Gilman has come a long way over the past 100 years. When we opened in 1917, our plumbers carried homemade wooden toolboxes and rode the trolley to service calls. At that time, two service calls a day was a lot. In 2017, we no longer take the trolley and our number of service calls per day has greatly increased with technology.

We opened our original location on Cary Street and have moved several times before building our current facility in Ashland. No matter where we are in Richmond or the surrounding areas, we remember our humble beginnings. I have been in this business for a long time. Plumbing is in my genes; my grandfather was also in the business.

I have been the owner and president of Gilman Heating, Cooling & Plumbing for 21 years. It is an honor and pleasure to serve our customers, some of whom have been with us since before I owned the company and others who are brand new homeowners. One thing has not changed in the last century – our commitment to customer service and to each and every one of you. Thank you for being a loyal Gilman customer. We look forward to the next 100 years!"
