Signs You Have a Generator That Needs Repairs
October 3rd, 2022Reasons You Aren’t Getting Enough Hot Water From Your Water Heater
September 19th, 2022Are people in your house starting to fight over who gets to shower first in the morning because the hot water has started to run out early? This is one of the first signs of a water heater that’s struggling to meet its normal capacity demands. This isn’t a problem you should ignore, since it often warns of a growing malfunction that can end up leaving you with a broken water heater and no hot water at all!
We offer professional water heater repair in Fairfax, VA to rescue faulty water heaters. We also handle replacing water heaters when repairs are too expensive or won’t deliver a long-term solution to the problem. Below are some of the possible reasons your water heater isn’t meeting your household’s customary hot water demands.
Why Your AC Is Leaving Hot Spots in Your House
September 5th, 2022The heat at the end of summer is often intense, so it might not surprise you to find your air conditioning system, after months of steady work, has started to struggle to keep all of your house comfortably cool. Even if it isn’t surprising, it’s still something you want fixed as soon as possible. When you’ve got an AC leaving rooms in the house too hot, it may mean the whole system is in jeopardy.
We’ll explain some of the different reasons an AC can start to provide uneven cooling and when you’ll need to call our team for air conditioning repair in Fairfax, VA.
Why Is My Heat Pump Not Switching to Cooling Mode?
August 22nd, 2022We think heat pumps are fantastic choices for home comfort, and we wish more people would look into them as an option for central heating and cooling around the year.
But heat pumps do have a few specific problems that can crop up during their service lives. One is when a heat pump becomes stuck in one mode or the other, such as a heat pump that won’t change over to cooling mode and will only provide heat or room temperature air.
If you’ve currently got a heat pump that staunchly refuses to cool your house, you may need to call our technicians for heat pump service in Damascus, MD. Below we’ll look at some possible causes of the “no-cool” heat pump and what can be done to resolve the problem.
Leaking Ducts Can Cause Many Problems for Your Home
August 8th, 2022No matter how well-built or durable your ductwork may be, leaks still happen. This is because HVAC systems are highly complex, and one small issue can affect the entire system. Moreover, although people often underestimate the negative effects of leaking ducts, they can actually wreak havoc on your home. Here is a closer look at how leaking ducts can cause many problems for your home.
A Guide to Air Conditioner Efficiency Ratings
July 25th, 2022When you’re planning for a new AC installation in Rockville, MD, you’ll have many bits of data to sort through. For example, the cooling capacity of the system (the amount of heat it can remove from a house in an hour) is a critical piece of information. Our technicians will help you locate the ideal capacity for your AC, since this has to be exact—too little or too much are both problems.
The other important AC stat you’ll look at is efficiency, or how well the AC uses electrical power to cool your house. Modern air conditioners are more efficient than ever before, and choosing a high-efficiency system can mean savings on your energy bills.
Below we’ll go over what you need to know about air conditioner efficiency ratings.
How Cool Can an AC Make My House?
July 11th, 2022You know your air conditioning system has limits. It can’t make your house as cold as the inside of the freezer in your refrigerator, after all. But when you look at the thermostat for your home, you might wonder if the AC could potentially go lower than the lowest setting on the thermostat. Most thermostats have a temperature setting low of 60–63°F, which is colder than most people want their homes to be. But theoretically, how cool can your central air conditioner make your home?
This is much more than a theoretical question! Understanding the limits on your AC’s cooling can help you know why air conditioning system sizing is so important and how air conditioners operate.
Why We Recommend Regular Duct Cleaning
June 27th, 2022People often think that duct cleaning isn’t something they need to have done regularly for their home—if it needs to be done at all. Because ducts remain mostly out of sight, it’s hard to tell just how dirty they can get, and this is why so many homeowners don’t even think about scheduling duct cleaning in Fairfax, VA.
But duct cleaning is an immensely beneficial service. You probably don’t need it done every year, but we recommend a schedule of every three to five years. If you’ve lived in your current home for five years or more, then we strongly recommend you call us up soon to have the job done. We provide thorough duct cleaning that will provide multiple benefits to your home. We’ve listed the reasons we recommend regular duct cleaning below.

The Trouble With AC Refrigerant Leaks
June 13th, 2022If you take good care of your home’s central air conditioner and regularly schedule maintenance for it, it should work with few problems for most of its service life. Repair problems can still crop up, however, and one we advise you to look out for is leaking refrigerant. This is a common issue with AC systems and also one of the most damaging.
