"I had them replace my entire HVAC system (furnance + AC). They did a great job through the whole process. Out of four quotes I received, they were the only ones that took the time to do a full heating and cooling load calculation for my house when they came to do an estimate in addition to making detailed measurements of our utility room to make sure anything they installed would fit. They gave me three proposals ranging from low-end, mid-range, and high end options and explained the equipment in each of them in detail, including documenting all the model numbers, efficiency ratings, and specs. What they recommended matched up with my research I did prior to receiving estimates. They were very responsive, knowledgeable, and professional so I gave them the job. The crew arrived on time, worked hard the whole day, were respectful of my house, and did not require supervision (although, they told me I was more than welcome to ask questions and watch anything they were doing). They cleaned up, explained the warranty and rebate options with all the paperwork already filled out so that all I had to do was sign--they even mailed both the warranty and rebate off for me. The whole process went great. While their prices were fair they were not the cheapest, but I have no doubt they did a great job, didn't cut corners, and will stand by their work if I experience any problems. They are a reasonably sized HVAC business and not a one-man-band shop like many places in the area, so I know they will likely still be around through the life of the warranty and are well staffed to respond to emergencies, including a 24/7 emergency service number. Overall, we're very happy with the new system and it's a huge improvement over what it replaced--both the AC and furnace are much quieter than the old units, more energy efficient, and perform better. It's been a month since the install and everything has been working fine without problems."

"My experience was fine. I went with this company instead of another company because of the reviews I read on Angie's List. It took them about a half a day to install the air conditioning unit. I think it was 3 workers that came out."

"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."

"The 2 techs first showed up after my dryer had died and cleaned the vents (inside - out and also from outside-in) as much as they could but said they needed me to have an operating dryer so that they could make sure everything was pushed out the side vent and airflow was good. They were very knowledgeable and honest which I appreciate when hiring any company without a first hand recommendation from my own friends/relatives first. They rescheduled a follow up appointment after my new dryer was delivered and were here the same morning and finished the cleaning and confirmed that everything was cleaned and working as it should now. I'll definitely hire them again next year and try to keep up an annual cleaning so it doesn't get so clogged next time. Highly recommended."
"We are very pleased with the job Dave did for us today. He was prompt and very courteous and did a professional job cleaning our carpets. Thank you for keeping the planned schedule as promised. We will recommend your company to our family and friends.

Stan"

Air Conditioning questions, answered by experts

When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.

You may be able to clean mold from your air conditioner in some cases. If the mold growth only takes up a small area, you can use either vinegar or bleach mixed with water to remove it. Larger areas of mold should be left to the professionals, though. It's also a good idea to leave mold removal to the pros if you are sensitive to mold or have asthma. 

AC leaks are common, and an HVAC pro can usually fix them. You may be able to resolve some leaks on your own, but a professional HVAC technician should handle most AC leak repair. If left ignored, an AC leak could cause serious damage to your system or leave you with expensive water damage, usually leading to more costly repairs or replacements.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.
