"Of all the HVAC companies I contacted, these guys had the best rates to come out and diagnose why my A/C was blowing hot air. Will came out and was very thorough and professional in diagnosing the issue and got me up and running in the same visit! He had great communication leading up to the meeting, and also spent a good amount of time talking to me about what was going on with my HVAC and giving advice. Very honest, knowledgeable, and didn't try to pressure upcharge me on anything but did offer additional services. I will definitely be hiring Will again for any other work and when it's time to replace my 14-year old HVAC (but hopefully not too soon!)"

"My HVAC air conditioning was not cooling my condo. The technician climbed a ladder to check my outdoor unit on the roof and noticed that the outdoor unit was not coming on. He discovered a loose wire and tightened it to fix the problem. He also checked the unit pressure and found that the charge was a little low. He added two pounds of refrigerant to charge up the system. Finally, he recommended using better filters and changing them more frequently. My HVAC air conditioning is now performing very efficiently. I'm very satisfied with the service received from SM Mechanical."

McCrea is a family owned business that has served our area since 1936. Financing and rebates are available on Trane systems installed by McCrea. Resistrictions apply and these are limited time offers call for details. "Its hard to stop a Trane"

"I had an absolutely terrible experience with McRae Air Conditioning and Heating. I purchased a home equipped with their HVAC system, and within just five months, the heat stopped working—right in the middle of winter during a snowstorm. My home was freezing at 50°F, so I called for service, which should have been covered under warranty. I scheduled an appointment, and the technician, after being several hours late, went to the wrong address, left a sticker on someone else’s door, and left without even trying to contact me. When I called back, the customer service rep was rude, dismissive, and completely unhelpful. He initially told me the technician was on the way and just 12 miles away—but after another hour of waiting, I called again only to be told that the technician had already “been to my house 2 hours ago” (the wrong one) and left a note. If the rep actually wanted to help, he would have told me this during my first call instead of wasting my time and leaving me sitting in the cold. Not once did the technician call me to confirm the address or check in after knocking on the wrong door. When I expressed my frustration, the rep rudely dismissed my concerns, saying, “Well, I had nothing to do with that,” and then interrupted me with, “Do you still want to rebook or not?” as if I had to stop talking or risk not getting another appointment. This was an emergency call in the middle of winter, and McRae handled it in the most unprofessional, careless, and disappointing way possible. If you’re considering using them for HVAC service, do yourself a favor and go with another company. I’ll update this review after the (hopefully successful) service call and speaking to the manager who was not there at 4 pm on a Wednesday."

"Rob was great from the estimate visit, to estimate delivery, and in coordinating the installation appointment (had to sub-contract in a roofer). On the day of service, Rob and Austin arrived on time (as did the roofers) and made quick work of the installation. It seems a rarity to find truly knowledgeable and friendly contractors that are both prompt and excellent communicators. This experience shined on all fronts. Will definitely be using Tim Kyle again. Appreciate the work Rob/Austin!"

"Horrible company, horrible service, still waiting after 14 days for an update. Claimed they ordered part, then found out they didn’t order the part, then they schedule an appointment and didn’t show up. Dispatch was rude and they didn’t return calls and messages. Same company misdiagnosed my mom’s HVAC system and she ended up getting it replaced only to find it still kept shutting off because it was a gas regulator that was the problem all along."

FAQs for ducts & vents installation and replacement projects in Ellicott City, MD

Return air vents aren't required in every room, but proper placement is essential for system efficiency. According to industry standards, you'll need one return vent for every 100 to 150 square feet of living space. Ideally, each room would have its own return vent, especially larger rooms exceeding 100 square feet. 

Without adequate return airflow, your HVAC system works harder, energy costs increase, and comfort decreases. A professional assessment can determine the optimal number and placement of return vents for your specific home layout.

Signs that your home needs additional return air vents include rooms that feel consistently stuffy, noticeable temperature variations between rooms, doors that slam shut when the HVAC system operates, or unexpectedly high energy bills. Excessive dust accumulation around supply vents can also indicate inadequate return airflow. 

If you experience these issues, consulting with an HVAC professional can help determine if adding return vents would improve your system's performance.

Supply vents deliver conditioned air into your living spaces, while return air vents draw room air back to your HVAC system for reconditioning. Supply vents push treated air into rooms, while return vents pull air from rooms back toward your heating and cooling equipment. 

Both components are essential for proper air circulation and system balance. Without sufficient return capacity, your HVAC system may experience pressure imbalances that reduce efficiency and comfort.

You should inspect and clean your return air vents at least once annually, according to industry recommendations. However, homes with pets, allergy sufferers, or noticeable dust buildup may benefit from more frequent cleaning. 

Regular maintenance helps maintain good indoor air quality and ensures your HVAC system operates efficiently. Professional duct cleaning, which addresses the entire system beyond just the visible vents, is recommended every few years, depending on your home's specific conditions.
