"Comfort by Design did a fantastic job with my water heater from start to finish. When I called, the receptionist was highly knowledgeable about scheduling and pricing, and she was quite willing to let me call other places since I was researching price and availability. I ended up sticking with Comfort by Design largely because the receptionist was not pushy, listened well to me, and had technicians available that day. I like hiring companies with whose employees listen to me and work with me to solve a problem, as opposed to pressuring me to choose them or to buy more than I'm comfortable with. My initial interaction with Comfort by Design met those criteria. A technician arrived within the time-frame I was quoted, and he had the part I thought was broken on my water heater. After diagnosing the issue, though, he discovered that there was at least one other broken/malfunctioning part that needed to be replaced. He showed me the problem and explained the process of replacing it. After discussing my options with the technician, I decided to replace the water heater. At no point did I feel pressured into making that decision. The best surprise of the day was that Comfort by Design was able to replace the water heater immediately. Another technician was available to immediately bring the water heater, and the two techs worked together to install the new one and remove the old one. They also carted the old one away. Before leaving, they patiently answered several other questions I had, and they explained and scheduled the necessary inspection of their installation. They did a great job respecting my property while moving the large water heaters, and they did a great job cleaning up after themselves. Finally, the cost was reasonable and about what I expected to pay. Custom by Design is definitely going to be the first place I call should I have any plumbing or HVAC (they also do HVAC!) needs in the future."

Heating and Air Conditioning questions, answered by experts

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

A dual evaporator coil is a specific design that allows the AC system to cool different compartments at different levels. It’s usually seen in refrigerators and similar appliances, but not in whole-house air conditioning systems. Talk with your AC technician about the best uses for a dual evaporator coil.

A one-stage air conditioner only has one setting, while a two-stage air conditioner has a high and low setting. A two-stage air conditioner costs between $500 and $2,500 more than a traditional air conditioner, but it has a longer lifespan and helps to increase energy efficiency. To make this decision, you should consider your energy needs and available budget.

A dirty AC filter can lower the efficiency of your system, so depending on how dirty it was, you may notice a temperature difference when you clean your filter. You can try other solutions if your AC isn’t blowing as cold as it used to. You can call in a local HVAC tech to make sure everything is running correctly, fix your air seal if it’s a window unit, and clean your coils.
