"They were thoughtful from the initial phone call, to the assessment of the problem, to the three options to replace my 17 year old HVAC system, to the installation of my new Lennox System. I absolutely recommend Chris and his team . Too, they all made friends with my exuberant 2 yr old dog!"

"The inspection went extremely well! The HVAC technician, Mike B., was extremely professional, arriving within the set 2 hour timeframe, even calling me within 10 mins of his arrival. I had a list of questions for the technician and the technician happily answered all of my questions along with showing me how to change the filter on our system. The technician explained the services that Grove Heating and Cooling offers without any pressure to purchase future services. We liked the service so much that we signed up for our next service with Grove Heating and Cooling, receiving a great discount off the flat rete price of $125."

"I couldn't be happier with the service I received from McCrea Heating and Air Conditioning Services of Maryland. Upon returning from vacation on a 100 degree July day, I found my old HVAC system basically dead (90 degrees in my kitchen!) ... Shane immediately came out to provide an estimate, we signed a contract on the spot, and he kindly provided some freon to hold me over until the new system could be installed. Brian and Nick showed up exactly on time to install the unit, used drop cloths to protect my flooring, and were exceedingly polite and professional throughout. I'd highly recommend this organization."

"I couldn?t be happier with the experience. Graham Solution handled the entire installation from start to finish, and the quality of the work was outstanding. He was professional, knowledgeable, punctual, and paid close attention to every detail. The installation was completed efficiently, everything was left clean when the job was finished, and the system works perfectly. It?s hard to find someone who takes this much pride in their work, and it definitely shows. I highly recommend him to anyone looking for reliable, high-quality HVAC installation. Excellent workmanship and great customer service from start to finish!"

"Carroll Mechanical delivered a 10/10 experience, from start to finish. From the first call, the Carroll Mechanical team demonstrated that they were knowledgable, ethical, and customer-first. First, they offered to help me troubleshoot, and they gave me some great tips that allowed me to try and fix the problem myself before they made a service call. As a not-so-handy guy, I realized that I needed the pros, so I requested on-site help. They immediately offered to come over on the day and time most convenient for me, and they spent time with me walking through the pros/cons of different HVAC options. Ultimately, the team explained the pros/cons of different remediation options, offered me an extremely competitive quote, and was transparent all along the way. I moved forward with a system replacement, which they were able to accommodate the same week(!!). The Carroll Mechanical team was timely, detail-oriented, and respectful of my home, and the HVAC system was installed as expected."

Heating and Air Conditioning FAQs, answered by experts

You may never need an AC recharge if there are no leaks. However, if your AC unit has a leak that cannot be patched appropriately, you’ll need an AC recharge every time the freon level drops low enough that it disrupts your system—this could be once every two to three years. It all depends on the size and frequency of the leak.

Yes, you can clean AC coils yourself. Just make sure that the power to your AC system is off before you begin. You’ll need some basic tools and supplies, including a soft brush, cloth, screwdriver, and a commercial or homemade cleaning solution. Cleaning your coils will only cost about $10.

Freon will go in the refrigerant lines near the back of your AC unit. Look for small ports with caps on a thin copper line—the Freon goes into those ports. You are best off hiring a licensed HVAC professional who can complete the job safely and correctly.

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.
