"I called last week to schedule a time to have someone come in and install a chandelier. Also discussed troubleshooting a switch for a bedroom ceiling fan. They recommended I have a new switch in hand before they came out. The day of I got a courtesy call when they were on their way. Nick arrived right on time. I showed him both issues. He was friendly and professional. He wore an N95 mask for protection the whole time so it felt very safe. He replaced the switch and receiver for the fan and it’s working as expected. He installed the chandelier, and checked the height before finishing up. He cleaned everything up well. Total cost was $275 for both tasks. I highly recommend them. I have used them before and will use them again."

"I had a new electrical line I wanted to run for a display light attached to a grandfather clock in our foyer. I also requested a switch be added to our wall panel by the front door to operate it. The job involved seeking a route for running wire behind the ceiling and drywall from our basement to the first floor of the house. The installation was complicated and obviously required a healthy amount of expertise in all respects. The work was accomplished with a minimal amount of mess (two small holes) and the quad switch panel added by our front door operates flawlessly. During the same visit they also replaced four decorative ceiling light fixtures and repaired a bad electrical outlet to boot. The workers were fast, efficient and friendly (even to my dog). I can't say enough about this company to do this justice. Very satisfied with my decision to give them a call."

"i have been using Shaw for 10 years and they have installed all my AC. i have told them that they do a good service but overcharging. they replace a dual run start device which should cost between $150 to $250 (hardware cost $30) for $500. it is upsetting to see them taking advantage of old clients."

"I claimed one of the “2 Toilet Tune-Up” Angi’s special with 4 Service Pros (Snell). When I contacted Snell I talked with a very nice lady who scheduled me to get 2 plumbers to come out the next day from Noon - 4pm. I was told they would call 20 minutes to 30 minutes before hand to let me know they were coming. I waited from Noon to 4:05pm, never received a phone call, and so I called Snell to find out if my plumbers were still coming. I was told that there was an emergency situation in Chantilly, VA, that required my 2 plumbers to go to Chantilly instead of my place that morning. I understand emergencies do happen, but Snell knew that my plumbers were needed for that major Chantilly, VA, leak from the morning. They should have called me once they found out that my assigned plumbers would not be able to come out to my place within my scheduled time appointment. I should not have had to wait from noon to 4pm and then have to call them to find out that they were not coming. I rescheduled with them, and set another appointment for the next day The next day Brandon Thomas came out, and he was outstanding. He is very friendly, professional, knowledgeable, efficient, and a very good plumber. My problems turned out to be quite different than I originally had thought and he explained my options. I went with the option that he recommended and am very happy with the results. He also gave me discounts to help make-up for my inconvenience for having to re-schedule the appointment. I definitely recommend Snell (4 Service Pros) to all my friends and family."

Heating Oil questions, answered by experts

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

Regular inspections, loop flushing, and checking heat exchangers help extend system lifespan.

Your HVAC manufacturer will give you instructions on how often you should service your system. Have your unit professionally serviced at least once a year when in doubt. 

Heat pump systems are different because they provide heating and cooling solutions for your home. In this case, you should have it serviced at least twice a year.

Leaks, poor airflow, reduced efficiency, and loop blockages are common problems requiring service.

Costs depend on system age, type, labor, and whether part replacements are necessary.

The homeowners guide to home care is here

From average costs to expert advice, get all the answers you need to get your job done.
