"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."

"Brian was the one who installed my air conditioning unit. excellent work, not only on time, took several hours but he did an excellent job. after the installation, he cleaned my room where it was installed. He worked neat clean. costumer support conact was provided for future service. He was very efficient. Very fair pricing, they also provide a discount on service during the winter time. He was the repairman for my old air conditioning unit. I am very very pleased with the service, I would highly recommend them."

"Valpo Services provided a great service from start to finish. Our house was built in 1925 and did not have air duct only window air conditioning units.
After we made the necessary research and requested several quotes, we decided
to use Valpo Services for the installation of a Central Air Unit. Walter came
to our home and provided us with several different options for a Central Air
Unit that would fit our home and needs. For the first time we did not feel pressured
to buy a specific Unit. At the end of the day Walter provided us with a really
competitive quote and showed us a timeline for the installation. Our questions
were always answered on a timely manner. Walter, Hector, Alex and the rest of
the team were always on time, worked hard to make sure the unit was installed on
time and always made sure we were satisfied with the work.  We are very pleased with the quality of work,
service and professionalism the company provided us with. We will highly
recommend Valpo Services to colleagues and friends and we will certainly continue
to use their services.

Air Conditioning questions, answered by experts

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.

Yes, it's normal for air conditioners to leak tiny amounts of water due to condensation. Under normal circumstances, all excess moisture travels to the drain pan to be pumped through your system's drain line. You should call a technician to diagnose the issue if you're noticing frequent leaking or pooling. It's also important to investigate if your homeowners insurance can cover water damage.

Deciding whether to replace just the AC coil or the entire system depends on the age of your unit and the overall cost. Replacing a coil is less expensive than a full system replacement, but it can still be a pricey repair. If your HVAC system is relatively new and still under warranty, or if the replacement cost is significantly lower than a new system, replacing the coil can be a worthwhile investment that restores efficiency and extends the unit's life. However, for older systems (nearing the end of their 10-15 year lifespan) or those with extensive damage, it is often more cost-effective to replace the entire AC unit. Mismatched coils in an older system can lead to inefficiency and future breakdowns, so a full replacement ensures optimal performance and avoids further costly repairs.

Look up your model number online to find additional information. Usually, you can just take a look at the old filter and find the brand name and dimensions to order a new one. When replacing the filter, always check that it’s pointed the right way to match the direction of your airflow. Many filters have arrows on them to help with this step.
